der Deplatforming Trump puts big tech under fresh scrutiny By www.chathamhouse.org Published On :: Fri, 22 Jan 2021 16:32:14 +0000 Deplatforming Trump puts big tech under fresh scrutiny Expert comment NCapeling 22 January 2021 The response of digital platforms to the US Capitol riots raises questions about online content governance. The EU and UK are starting to come up with answers. The ‘deplatforming’ of Donald Trump – including Twitter’s announcement that it has permanently banned him due to ‘the risk of further incitement of violence’ after the riots in the US – shows once more not only the sheer power of online platforms but also the lack of a coherent and consistent framework for online content governance. Taking the megaphone away from Trump during the Capitol riots seems sensible, but was it necessary or proportionate to ban him from the platform permanently? Or consistent with the treatment of other ‘strongmen’ world leaders such as Modi, Duterte and Ayatollah Ali Khamenei who have overseen nationalistic violence but whose accounts remain intact? Such complex decisions on online expression should not made unilaterally by powerful and unregulated tech actors, but instead should be subject to democratic oversight and grounded in the obligations of states and responsibilities of companies under international human rights law. The speed and scale of digital information has left governments across the world struggling with how to tackle online harms such as hate speech, extremist content and disinformation since the emergence of mass social media 15 years ago. The US’s hallowed approach to the First Amendment, under which speech on public issues – even hate speech – occupies the highest rank and is entitled to special protection, has contributed to a reluctance to regulate Silicon Valley’s digital platforms. But the irony is that by not regulating them, the government harmed freedom of expression by leaving complex speech decisions in the hands of private actors. Meanwhile at the other extreme is the growing number of illiberal and authoritarian governments using a combination of vague laws, censorship, propaganda, and internet blackouts to severely restrict online freedom of expression, control the narrative and, in some cases, incite atrocities. Regulation is on the way The happy medium – flexible online content regulation providing clarity, predictability, transparency, and accountability – has until now been elusive. But even before the deplatforming of Trump, 2021 was set to be the year when this approach finally gained some traction, at least in Europe. The EU’s recently-published draft Digital Services Act puts obligations on dominant social media platforms to manage ‘systemic risks’, for example through requirements for greater transparency about their content decisions, algorithms used for recommendations, and online advertising systems. The UK will shortly publish its Online Safety Bill, which will establish a new regulatory framework for tackling online harms, including the imposition of a duty of care and codes of conduct on Big Tech, to be overseen by an independent regulator (Ofcom). Both proposals are based on a ‘co-regulatory’ model under which the regulator sets out a framework substantiated with rules by the private sector, with the regulator performing a monitoring function to ensure the rules are complied with. Both also draw on international human rights standards and the work of civil society in applying these standards in relation to the online public square, with the aim of increasing control for users over what they see online, requiring transparency about tech companies’ policies in a number of areas, and strengthening the accountability of platforms when they fall foul of the regulation. The procedure for both proposals has also been inclusive, involving extensive multi-stakeholder consultations with civil society organizations and Big Tech, and the proposals will be subject to scrutiny in 2021, notably from the EU and UK parliaments. Both proposals are at an early stage, and it remains to be seen whether they go far enough – or indeed will have a chilling effect on online platforms. But as an attempt to initiate a dialogue on globally coherent principles, they are positive first steps. They also provide food for thought for the new Joe Biden administration in the US as it turns its attention to the regulation of Big Tech. For some time civil society – most prominently David Kaye, the former UN Special Rapporteur on freedom of expression and opinion – have called for content regulation to be informed by universal international human rights law standards. The EU and UK are peculiarly well-placed to take the lead in this area because European countries have for decades been on the receiving end of judgments from the European Court of Human Rights on the appropriate limits to freedom of expression in cases brought under the European Convention on Human Rights. In deciding these cases, the court has to balance the right to freedom of expression against the restrictions imposed – for example in the context of incitement to violence, political debate, and satire. Deciding where to draw the line on what can and cannot be expressed in a civilised society which prizes freedom of expression is inevitably a difficult exercise. International human rights law provides a methodology that inquires whether the interference to freedom of expression was prescribed by law and pursues a legitimate aim, and also whether it was necessary in a democratic society to achieve those aims – including whether the interference was necessary and proportionate (as for example in Delfi AS v Estonia, which involved a news portal failing to take down unlawful hate speech). To be effective, online content regulation has to bite on tech companies, which is a challenge given the internet is global but domestic law normally applies territorially. The EU’s proposals have an extraterritorial element as they apply to any online platforms providing services in the EU regardless of where the platform is headquartered. Further, both the EU and UK want to give the regulator strong enforcement powers – it is proposed for example that Ofcom will have powers to fine platforms up to ten per cent of their turnover for breaches. Although the proposals would not apply directly to the deplatforming of Trump which occurred in the US, the philosophy behind the EU and UK approach is likely to have an impact beyond European shores in promoting a co-regulatory model that some of the bigger tech companies have been inviting for some time, reluctant as they are to ‘play God’ on content moderation decisions without reference to any regulatory framework. In the absence of regulation, the standards of tech platforms such as Facebook and Twitter have already evolved over time in response to pressure from civil rights groups, users, and advertisers, including updated policies on protecting civic conversation and hate speech. Facebook has also set up an independent Oversight Board, whose members include leading human rights lawyers, to review decisions on content including – at its own request – the decision to indefinitely suspend Trump from Facebook and Instagram. Decisions on the Board’s first tranche of cases are expected imminently. Gatekeeper status is key Online content regulation also needs to address the role of Big Tech as the ‘digital gatekeepers’, because their monopoly power extends not just to editorial control of the news and information we consume, but also to market access. The decision of Apple, Google, and Amazon to stop hosting right-wing social network Parler after it refused to combat calls for violence during the US Capitol riots was understandable in the circumstances, but also underlined the unilateral ability of Big Tech to decide the rules of the market. Again, it is Europe where efforts are underway to tackle this issue: the EU’s draft Digital Market Act imposes obligations on online gatekeepers to avoid certain unfair practices, and the UK’s new Digital Markets Unit will have powers to write and enforce a new code of practice on those technology companies with ‘substantial and enduring’ market power.

Enter email address Subscribe In the US, Biden’s team will be following these developments with interest, given the growing bipartisan support for strengthening US antitrust rules and reviving antitrust enforcement. The EU’s recently published proposals for an EU-US tech agenda include a transatlantic dialogue on the responsibility of tech platforms and strengthened cooperation between antitrust authorities on digital markets. Ultimately a consistent – and global – approach to online content is needed instead of fragmented approaches by different companies and governments. It is also important the framework is flexible so that it is capable of applying not only to major democracies but also to countries where too often sweeping state regulation has been used as a pretext to curtail online expression online. The pursuit of a pluralistic framework tailored to different political and cultural contexts is challenging, and international human rights law cannot provide all the answers but, as a universal framework, it is a good place to start. The raft of regulatory measures from the EU and UK means that, regardless of whether Trump regains his online megaphone, 2021 is set to be a year of reckoning for Big Tech. Full Article
der Facebook's power under scrutiny as Trump ban upheld By www.chathamhouse.org Published On :: Thu, 06 May 2021 09:04:43 +0000 Facebook's power under scrutiny as Trump ban upheld Expert comment NCapeling 6 May 2021 Keeping Donald Trump’s Facebook ban in place shows the vast power social media platforms hold, raising questions of whether that power is appropriately used. Kate Jones From a human rights perspective, the Oversight Board’s decision is a strong one, and not at all surprising. The board decided Facebook was right to suspend the former president’s access to post content on Facebook and Instagram, but not indefinitely. It found Donald Trump’s posts violated Facebook’s community standards because they amounted to praise or support of people engaged in violence and that, applying a human rights assessment, Facebook’s suspension of Trump was a necessary and proportionate restriction of his right to freedom of expression. It is in content amplification, not just content moderation, that Facebook should face scrutiny and accountability for the sake of the human rights of its users However the board also found Trump’s indefinite suspension was neither in conformity with a clear Facebook procedure nor consistent with its commitment to respect human rights. Its decision requires Facebook to make a new decision on the future of Donald Trump’s account, grounded in its rules. While opinions on this result will differ, the increased call for clear and accessible rules and respect for human rights in their implementation that the Oversight Board brings to Facebook’s operations is welcome. But the Oversight Board’s powers are limited to content moderation – Facebook declined to answer the board’s questions about amplification of Trump’s posts through the platform’s design decisions and algorithms. This limitation on the board’s role should be lifted. It is in content amplification, not just content moderation, that Facebook should face scrutiny and accountability for the sake of the human rights of its users. Fundamentally, human rights is not a veneer which can mask or legitimize underlying power dynamics or public policy – those still fall to be assessed for themselves. The Trump/Facebook saga does highlight the vast power Facebook and other major social media platforms have over political discussion and persuasion. Through granting or denying, or through amplifying or quietening the voices of political figures, Facebook has the power to shape politics, electorates, and democratic processes. Improving content moderation through the Oversight Board, although important, does little to constrain that power. Facebook itself, unlike a government, has no accountability to the general public, and the Oversight Board must not distract us from the need for a full conversation about the extent to which Facebook’s power is appropriately held and properly wielded. Emily Taylor This decision marks a coming of age for Facebook’s content moderation process. For years, decisions to take down content or ban users have been opaque, conducted by a human workforce that Facebook and other platforms have been hesitant to acknowledge. The platforms have also been worried that being seen to exercise an editorial function might put at risk the legal protections which prevent the platforms being held responsible for user-generated content. When the Oversight Board was first posited, observers questioned whether a body funded by Facebook could properly exercise a legitimate appeals function. Now there is a reasoned decision which partly supports the decision to de-platform a serving president, but also takes issue with the indefinite nature of the ban. If the process is to gain respect as a truly independent oversight on the platform’s decisions, greater transparency over the identity of decision-makers will be needed Facebook specifically asked the Oversight Board to consider specific challenges involved when the person involved is a political leader. The board concluded that Trump’s ‘status as head of state with a high position of trust not only imbued his words with greater force and credibility but also created risks that his followers would understand they could act with impunity’. The storming of the US Capitol and role President Trump played in stirring up the violence underlined that political leaders’ words can motivate others to take harmful actions. Just as the events of January 6 remain shocking, it remains shocking that private platforms have exercised the power to curb the speech of a US president. It also remains shocking that the platforms sat back and took no action over the previous four years, but waited until the final days of the transition. The board’s decision is an evolution in private-sector content moderation, with a diverse board giving a reasoned opinion on a Facebook decision. But to fully comply with the principles of open justice, board decisions should include more detail on the individuals who have made the decision – at present, it appears all members of the board review the decision but it is not clear which individuals were involved in its drafting, or that they were clear from conflicts. If the process is to gain respect as a truly independent oversight on the platform’s decisions, greater transparency over the identity of decision-makers will be needed.

Just because companies have the financial resources to do it, does not mean they necessarily should. Yet no other international governance or arbitration system has emerged to handle the complexities of platform power over speech. In the context of that vacuum, the Oversight Board’s decision is a welcome step. Full Article

And how will Merkel be remembered? In the wake of the storming of Capitol Hill on 6 January 2021, social media platforms took steps to remove former President Donald Trump from their websites for infringing community standards. This step was welcomed by many, but also raised serious questions about the power of social media companies to limit free speech and censor elected officials. The suspension of President Trump from Facebook was referred to the Oversight Board, an independent body of experts set up to scrutinise the platform’s content moderation decisions. In this episode, Ben speaks to Thomas Hughes and Kate Jones about the outcome of the Oversight Board’s inquiry into the Trump suspension, and the wider implications for content moderation on social media. Then Lara is joined by Hans Kundnani to assess the political outlook in Germany and reflect on the legacy of outgoing Chancellor Angela Merkel. Full Article
der A novel stress-inducible CmtR-ESX3-Zn2+ regulatory pathway essential for survival of Mycobacterium bovis under oxidative stress [Microbiology] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 Reactive oxygen species (ROS) are an unavoidable host environmental cue for intracellular pathogens such as Mycobacterium tuberculosis and Mycobacterium bovis; however, the signaling pathway in mycobacteria for sensing and responding to environmental stress remains largely unclear. Here, we characterize a novel CmtR-Zur-ESX3-Zn2+ regulatory pathway in M. bovis that aids mycobacterial survival under oxidative stress. We demonstrate that CmtR functions as a novel redox sensor and that its expression can be significantly induced under H2O2 stress. CmtR can physically interact with the negative regulator Zur and de-represses the expression of the esx-3 operon, which leads to Zn2+ accumulation and promotion of reactive oxygen species detoxication in mycobacterial cells. Zn2+ can also act as an effector molecule of the CmtR regulator, using which the latter can de-repress its own expression for further inducing bacterial antioxidant adaptation. Consistently, CmtR can induce the expression of EsxH, a component of esx-3 operon involved in Zn2+ transportation that has been reported earlier, and inhibit phagosome maturation in macrophages. Lastly, CmtR significantly contributes to bacterial survival in macrophages and in the lungs of infected mice. Our findings reveal the existence of an antioxidant regulatory pathway in mycobacteria and provide novel information on stress-triggered gene regulation and its association with host–pathogen interaction.

Cities are critical to tackling the pressing environmental challenges of our time. While they now account for an estimated 75 per cent of global CO2 emissions, cities also offer a unique opportunity for devolved leadership on climate action. At the recent COP26, some significant progress was made in elevating cities’ position on climate action with a flurry of announcements and commitments. For example, more than 1,000 cities are now committed to the Cities Race to Zero and C40’s Clean Construction Declaration saw multiple cities committing to at least halving emissions from initial construction of buildings by 2030. A raft of financing commitments were also made to improve urban resilience in the face of climate change. This builds on existing momentum before COP26. Over 50 world cities are now on track to meet Paris Agreement and the Marrakech Partnership is further enabling collaboration between governments and cities within the UNFCCC processes. Therefore, how we design, build, govern and use our urban places will be a key factor for decarbonization and climate change adaptation. On the back of COP26, this panel brings together leaders from across urban development sectors to discuss the progress cities have already made, whether progress at COP26 was enough, and what more needs to be done to scale action and ambition internationally.

der ARID4B is critical for mouse embryonic stem cell differentiation towards mesoderm and endoderm, linking epigenetics to pluripotency exit [Developmental Biology] By www.jbc.org Published On :: 2020-12-18T00:06:18-08:00 Distinct cell types emerge from embryonic stem cells through a precise and coordinated execution of gene expression programs during lineage commitment. This is established by the action of lineage specific transcription factors along with chromatin complexes. Numerous studies have focused on epigenetic factors that affect embryonic stem cells (ESC) self-renewal and pluripotency. However, the contribution of chromatin to lineage decisions at the exit from pluripotency has not been as extensively studied. Using a pooled epigenetic shRNA screen strategy, we identified chromatin-related factors critical for differentiation toward mesodermal and endodermal lineages. Here we reveal a critical role for the chromatin protein, ARID4B. Arid4b-deficient mESCs are similar to WT mESCs in the expression of pluripotency factors and their self-renewal. However, ARID4B loss results in defects in up-regulation of the meso/endodermal gene expression program. It was previously shown that Arid4b resides in a complex with SIN3A and HDACS 1 and 2. We identified a physical and functional interaction of ARID4B with HDAC1 rather than HDAC2, suggesting functionally distinct Sin3a subcomplexes might regulate cell fate decisions Finally, we observed that ARID4B deficiency leads to increased H3K27me3 and a reduced H3K27Ac level in key developmental gene loci, whereas a subset of genomic regions gain H3K27Ac marks. Our results demonstrate that epigenetic control through ARID4B plays a key role in the execution of lineage-specific gene expression programs at pluripotency exit. Full Article
der Structural and biochemical characteristics of two Staphylococcus epidermidis RNase J paralogs RNase J1 and RNase J2 [Protein Structure and Folding] By www.jbc.org Published On :: 2020-12-04T00:06:06-08:00 RNase J enzymes are metallohydrolases that are involved in RNA maturation and RNA recycling, govern gene expression in bacteria, and catalyze both exonuclease and endonuclease activity. The catalytic activity of RNase J is regulated by multiple mechanisms which include oligomerization, conformational changes to aid substrate recognition, and the metal cofactor at the active site. However, little is known of how RNase J paralogs differ in expression and activity. Here we describe structural and biochemical features of two Staphylococcus epidermidis RNase J paralogs, RNase J1 and RNase J2. RNase J1 is a homodimer with exonuclease activity aided by two metal cofactors at the active site. RNase J2, on the other hand, has endonuclease activity and one metal ion at the active site and is predominantly a monomer. We note that the expression levels of these enzymes vary across Staphylococcal strains. Together, these observations suggest that multiple interacting RNase J paralogs could provide a strategy for functional improvisation utilizing differences in intracellular concentration, quaternary structure, and distinct active site architecture despite overall structural similarity.

der Mapping the transition state for a binding reaction between ancient intrinsically disordered proteins [Molecular Biophysics] By www.jbc.org Published On :: 2020-12-18T00:06:18-08:00 Intrinsically disordered protein domains often have multiple binding partners. It is plausible that the strength of pairing with specific partners evolves from an initial low affinity to a higher affinity. However, little is known about the molecular changes in the binding mechanism that would facilitate such a transition. We previously showed that the interaction between two intrinsically disordered domains, NCBD and CID, likely emerged in an ancestral deuterostome organism as a low-affinity interaction that subsequently evolved into a higher-affinity interaction before the radiation of modern vertebrate groups. Here we map native contacts in the transition states of the low-affinity ancestral and high-affinity human NCBD/CID interactions. We show that the coupled binding and folding mechanism is overall similar but with a higher degree of native hydrophobic contact formation in the transition state of the ancestral complex and more heterogeneous transient interactions, including electrostatic pairings, and an increased disorder for the human complex. Adaptation to new binding partners may be facilitated by this ability to exploit multiple alternative transient interactions while retaining the overall binding and folding pathway. Full Article
der EU Budget Battle Could Undermine its International Ambitions By www.chathamhouse.org Published On :: Fri, 17 Jul 2020 13:09:58 +0000 17 July 2020 Alice Billon-Galland Research Associate, Europe Programme @alicebillon LinkedIn Vassilis Ntousas Stavros Niarchos Foundation Academy Fellow, Europe Programme @vntousas LinkedIn EU’s heated budget negotiations risk producing a compromise at the expense of its longer-term international agenda.

Photo by Thierry Monasse/Getty Images. With all EU economies still reeling from COVID-19, the ongoing heated deliberations on the bloc’s next budget, which will determine the amount of money matching its priorities for the next seven years, have taken on an urgency rarely felt in Brussels.Relying in part on an unprecedentedly large volume of jointly issued debt, the European Commission’s plan for a €750 billion coronavirus recovery instrument is embedded within a revamped proposal for the EU’s long-term budget, of €1.1 trillion for the 2021-27 period. Now the ball is in the member states’ court. All seem to agree that getting the EU budget right is crucial to fostering an economic recovery and ensuring the Union is on the right track towards its long-term pre-COVID objectives, from increasing its strategic autonomy to reaching climate neutrality by 2050. However, stark differences persist as to what that means in practice.Most of the core divisions predate the pandemic’s outbreak. In a special European Council meeting in February, leaders failed to find common ground on the Union’s first post-Brexit budget. Net contributor countries, such as Austria, Denmark, Sweden and the Netherlands — the so-called ‘Frugal Four’— refused to agree to higher overall spending and instead advocated for cuts in the Common Agricultural Policy or cohesion funds, meeting the resistance of states like France and Portugal.These early divisions foreshadowed the risk of a budget compromise that would leave little space for new policy priorities. The COVID-induced economic crisis has made a traditionally fraught political process even more difficult, putting the squeeze on what were previously priority areas of funding.The Frugal Four agree on the need for the coronavirus recovery plan but vehemently oppose the volume of grants or the issuance of too much common debt in the proposed instrument, reflecting the unpopularity of these proposals with their domestic audiences. Hungary has also threatened to derail progress on the EU’s rescue plan if rule of law criteria are weaved into mechanisms for the allocation of EU funding.As European leaders reconvene at the 17-18 July Council meeting, EU Council President Michel proposed a revised 'negotiating box' in preparation for the discussions. The document, which tries to bridge these intra-bloc divisions, bolts the demands for short-term recovery onto the EU’s longer-term ambitions. For instance, it sets an increased target of 30 per cent of funding to go toward climate-related projects, which is necessary for the Union’s green transformation. It also retains the link between the rule of law and EU funding — despite Budapest’s opposition — which is critical for the bloc’s internal accountability and transparency, and external credibility. Furthermore, it proposes a set of new mechanisms through which the EU can sustainably raise its own revenue, including a plastics levy as well as more controversial carbon border tax and digital levy.Yet in several other critical ways, Michel’s proposals fall short. This is particularly true for some of the more ‘geopolitical’ goals of the Union, as previously expressed by Commission president Ursula von der Leyen, or the repeated calls by the Union’s high representative that the EU should learn to use the language of power.For all the rhetoric around the EU’s need to boost its ability to act more autonomously in the field of security and defence, reductions in important thematic programmes in this domain could result in a critical loss of momentum, if confirmed. For instance, in Michel’s proposals, flagship defence initiatives such as the European defence fund and the military mobility plan are facing cuts of about 39 per cent and 74 per cent respectively (to some €7 billion for the former and €1.5 billion for the latter) compared with the initial Commission proposal of 2018.Moreover, the tragic developments at the Greece-Turkey border in the beginning of the year might have brought migration back to the forefront of the EU’s attention, but the overall funding for migration and border management is also significantly lower compared to initial proposals. This serves as another example of a discrepancy between the figures on the table today and those that the EU commission had previously regarded as necessary to address the challenges the bloc faces.Similarly, under the Council president’s latest proposal, the combined funding allocated for the EU’s external action (under the ‘Neighbourhood and the World’ heading) is lower than the figures in the Commission’s May announcements – from €118.2 billion to €113.9 billion overall. This represents an increase compared to the previous EU budget, but it is not in line with the elevated ambitions recognized by the Commission in May, which have only been made more compelling by the pandemic.Brokering a deal in EU budget negotiations has always been a brutal affair, requiring sacrifices and compromise under the pressure of a ticking clock. 2020 was never likely to be an exception to this rule; but the pandemic has complicated the politics and raised the stakes.The risk is that the budget negotiations lead to a compromise which, while delivering a historic coronavirus package, does not adequately support some of the key elements of the Union’s long-term agenda, especially its international ambitions.

der Unrest Threatens Ethiopia’s Transition Under Abiy Ahmed By www.chathamhouse.org Published On :: Fri, 24 Jul 2020 10:40:55 +0000 24 July 2020 Abel Abate Demissie Associate Fellow, Africa Programme @abele_a LinkedIn Ahmed Soliman Research Fellow, Horn of Africa, Africa Programme @AhmedSolHoA Ethiopia is experiencing a turbulent transition. The uncompromising approach of political forces threatens to tear the country apart and reverse the hard-won gains made in recent years. GettyImages-1227453952.jpg Burned buildings which were set on fire during the violence after the assassination of Oromo's pop singer Hachalu Hundessa are seen in Shashamene, Ethiopia on 12 July 2020. Photo: Getty Images. Violent unrest in Addis Ababa and the surrounding Oromia region has led to the loss of over 177 lives, with the detention of thousands and widespread destruction to property. The rise of identity-based conflict and related political tension is the most severe test of Prime Minister Abiy Ahmed’s leadership since he came to power two years ago.Protests erupted after the assassination on the 29th of June of Hachalu Hundessa, a prominent Oromo singer and activist. They spiralled into widespread rioting, looting and arson which devastated some towns. Targeted attacks and killings, particularly against ethnic minorities in Oromia, have damaged communities’ social fabric and heightened regional tensions.The motives behind Hachalu’s murder are not fully understood. Suspects linked to a militant faction of the Oromo Liberation Front (OLF) have been arrested, while the government has blamed the Tigray People’s Liberation Front (TPLF) and certain prominent activist-politicians for inciting ethnic violence and attempting to derail Ethiopia’s fragile political liberalization. With investigations not yet concluded, any exploitation of this tragedy for political gain and without adequate due process is likely to further erode trust in the government and public institutions. Ethiopia’s progress halting under Abiy AhmedThe prime minister came to power with a vision of national unity – encapsulated in his ideology of Medemer – and implemented a raft of reforms aimed at strengthening institutions and increasing political space, inclusivity and freedoms. Abiy was awarded the 2019 Nobel Peace Prize for Ethiopia’s rapprochement with Eritrea, alongside domestic progress. He was lauded for mediating within the region, including in Sudan following the ouster of Omar al-Bashir.However, Ethiopia’s simmering ethnic and political divisions have deep roots, with structural problems that have been insufficiently addressed under Abiy’s helm. These include conflicting narratives about Ethiopia’s history, an unfinished federal project and tensions over the division of power between the centre and the regions.There is also the desire for better representation from various ethnic groups, linked to the pursuit of greater autonomy in many places, notably in the ethnically diverse southern region. Reforms have increased expectations among competing constituencies, heightening tensions further.There are signs that Ethiopia is sliding dangerously backwards, particularly on security and democracy. The country has seen worsening levels of militant ethno-nationalism and inter-communal violence, a dangerous standoff between the federal government and Tigray region, and an increase in politically motivated deaths.This has been compounded by the government turning to familiar, heavy-handed and securitized responses to law and order challenges, including intimidation and mass arrests of civilians, opposition politicians and journalists, and shutting off the internet. The Ethiopian Human Rights Commission called for security forces to refrain from punitive measures and pursue conciliatory approaches in implementing the state of emergency measures brought in to deal with COVID-19.The country is also facing a triple economic shock caused by the pandemic, renewed instability and devastating desert locust swarms. The IMF recently reduced Ethiopia’s GDP growth projections for 2019/2020 to 3.2 percent down from 6.2 percent and the country has estimated that 1.4 million workers will be affected by the pandemic, particularly in the service and manufacturing sectors.The impact on agriculture, which accounts for a third of GDP and on which most Ethiopian’s depend for their livelihoods, is expected to be severe. In addition to shaking investor confidence, the likely impact on livelihoods, food security and poverty levels makes it harder for the government to maintain public support and could add to instability.Political turmoil caused by election delayThe situation has been exacerbated by the indefinite postponement of elections that were due in August 2020, as a result of COVID-19.Efforts to avoid a crisis of legitimacy for the government caused by the end of parliament’s term in October 2020, led to a decision on the way forward being taken by the Council of Constitutional Inquiry (CCI). This group of legal experts led by the President of the Supreme Court, gave the ruling Prosperity Party (PP) an open-ended extension of their term, rubberstamped by the House of Federation, with no limits set on their powers during the interim period.This decision sets a dangerous precedent and is a missed opportunity to achieve compromise and advance the democratic process. The lack of inclusion has angered opposition groups, with whom the government has had little genuine dialogue. Many in the opposition had advocated for a transitional or technocratic government during the interim, despite risks of further divisions and a vacuum of authority, and accuse the PP of manipulating institutions to stay in power.Furthermore, the TPLF, the ruling party in the Tigray region and formerly the dominant national political force, is pushing forward with its intention to hold unilateral regional elections. It formed a new regional electoral commission, in spite of objections from the national electoral board and the government, which has implied it could use force to stop the elections. This rising enmity between the PP and the TPLF is extremely worrying and requires immediate de-escalation.A pathway to genuine dialogue and reconciliationEthiopia’s problems can only be resolved through dialogue, compromise and reconciliation. Escalating tensions, particularly between the federal government, Tigray and Oromo opposition groups risk furthering instability and fragmentation. One way to establish confidence would be for a group of respected Ethiopian personalities (elders and religious leaders) to lead a political dialogue, with actors carefully chosen and vetted to ensure the buy-in of government, opposition parties and the public, and supported by Ethiopia’s regional and international partners.Once established, an initial goal of such a platform would be to induce elites, populist leaders, activists and influential regional media to stop exploiting division and violence for narrow gain. Priority agenda issues include the election timetable and required institutional and legal reforms, the role of the opposition during the interim period, strengthening reconciliation efforts, and the need to carefully manage autonomous security forces within regional states.The prime minister can still weather the storm and implement his vision of a unified multinational Ethiopia based on the values of democracy, rule of law and justice, but only if the government and other stakeholders do all they can to reduce tensions and preserve peace at this critical juncture. COVID-19 and the associated economic impacts have deepened the country’s multifaceted problems, which can only be resolved by political actors committing themselves towards inclusive dialogue and reconciliation, as they seek to forge a shared common future.

der Conflict-Related Sexual Violence in Ukraine: An Opportunity for Gender-Sensitive Policymaking? By www.chathamhouse.org Published On :: Mon, 17 Aug 2020 23:55:05 +0000 18 August 2020 Kateryna Busol Robert Bosch Stiftung Academy Fellow, Russia and Eurasia Programme @KaterynaBusol LinkedIn Meaningful change is needed in Ukraine’s response to the conflict-related sexual violence, which affects both women and men. 2020-08-18-Ukraine-Intl-Womens-Day.jpg Ukrainian feminists and human rights activists carry posters at an International Women's Day protest in Kyiv, Ukraine on 8 March 2019. Photo: Getty Images. The virus of violenceAccording to the UN (para. 7) and the International Criminal Court (ICC, para. 279), conflict-related sexual violence (CRSV) is quite prevalent in hostilities-affected eastern Ukraine. Both sexes are subjected to sexualized torture, rape, forced nudity, prolonged detention in unsanitary conditions with members of the other sex and threats of sexual violence towards detainees or their relatives to force confessions. Men are castrated. Women additionally suffer from sexual slavery, enforced and survival prostitution, and other forms of sexual abuse. Women are more exposed to CRSV: in the hostilities-affected area, every third woman has experienced or witnessed CRSV as opposed to every fourth man.COVID-19 has redirected funding priorities, affecting the availability of medical and psychological help for CRSV survivors worldwide. In Ukraine, the very reporting of such violence, stigmatized even before the pandemic, has been further undermined by the country-wide quarantine-induced restrictions on movement and the closure of checkpoints between the government-controlled and temporarily uncontrolled areas.Addressing CRSV in UkraineThe stigma of CRSV, the patchy domestic legislation, and the unpreparedness of the criminal justice system to deal with such cases prevent the authorities from properly helping those harmed in the ongoing Russia-Ukraine armed conflict.CRSV is equally traumatizing yet different in nuance for men and women. Female victims often choose not to report the violence. Women avoid protracted proceedings likely to cause re-traumatization and the disclosure of their experience, which could be particularly excruciating in small communities where everybody knows everyone.Men also struggle to provide their accounts of CRSV. Their suppressed pain and shame of genital mutilation and other CRSV result in sexual and other health disfunctions. Combined with the post-conflict mental health struggles, this has been shown to lead to increased domestic violence and even suicide.The very investigation of CRSV in Ukraine is challenging. Certain tests and examinations need to be done straight after an assault, which in the context of detention and grey zones of hostilities is often impossible. Specialized medical and psychological support is lacking. Investigators and prosecutors are hardly trained to deal with CRSV to the point that they do not ask questions about it during the interviews. Burdened by trauma and stigma, survivors are inclined to report torture or inhuman treatment, but not the sexualized aspects thereof.Seven years into the conflict, the state still has not criminalized the full spectrum of CRSV in its domestic law. Ukraine’s Criminal Code contains a brief list of the violations of the rules and customs of warfare in article 438. It prohibits the inhuman treatment of civilians and POWs but does not list any types of CRSV.The article has an open-ended reference to Ukraine’s ratified international treaties, from which the responsibility for other armed conflict violations may be derived. For the more detailed norms on CRSV, Ukraine should refer at least to Geneva Convention IV protecting civilians and two additional protocols to the Geneva Conventions, to which it is a party.However, the novelty of the war context for Ukrainian investigators, prosecutors and judges and their overcautiousness about the direct application of international conventions mean that in practice, observing the treaty or jurisprudential instruction on CRSV has been slow.Use of the Criminal Code’s articles on sexual violence not related to an armed conflict is not viable. Such provisions fail to reflect the horrible variety and complexity of CRSV committed in hostilities. They also envisage lesser punishment than a war crime of sexual violence would entail. Cumulatively, this fails to account for the intention of a perpetrator, the gravity of the crime and the trauma of its victims.The lack of public debate and state action on CRSV understates its magnitude. Ukraine should break its silence about CRSV in Donbas and make addressing this violence part of its actionable agenda - in law and in implementation.Ukraine should incorporate all war crimes and crimes against humanity of CRSV in its domestic legislation; ensure a more gendered psychological and medical support for both sexes; establish rehabilitation and compensation programmes for CRSV survivors; create special victims and witness protection schemes; consider the different stigmatizing effects of CRSV on men and women in criminal proceedings and engage the professionals of the same sex as the victim; map CRSV in the bigger picture of other crimes in Donbas to better understand the motives of the perpetrators; submit more information about CRSV to the ICC and educate the public to destigmatize the CRSV survivors.The drafters of Ukraine’s transitional justice roadmap should ensure that it highlights CRSV, adopts a gendered approach to it and endorses female participation as a crucial component of reconciliation and broader policymaking.Embracive policymakingAlthough ‘the discriminatory line almost inevitably hurts women,’ 'every gender discrimination is a two-edged sword’, Ruth Bader Ginsburg famously argued before the US Supreme Court. This could not be more relevant for Ukraine. The conflict - and lockdown-related violence has reverberated deeper within Ukrainian society, raising fundamental questions about the roles of both sexes and gender equality.The failure to address CRSV and its different stigmas for both sexes mirrors the general lack of sustainable gender lenses in Ukraine's policymaking. It is no coincidence that a June 2020 proposal for gender parity in political parties coincided with another spike of sexist remarks by top officials. While women get access to more positions in the army, sexual harassment in the military is investigated slowly. Despite all the impressive female professionals, no woman made it to the first four-member consultative civic group in the Minsk process. Such lack of diversity sends an unfortunate message that women are not important for Ukraine’s peace process.Ginsburg said, ‘women belong in all places where decisions are being made.’ CRSV against either sex won’t be addressed properly until both sexes contribute with their talents and their grievances to all pillars of Ukraine’s state governance and strategy. Ukraine should look to engage professional women - and there are plenty - to join its public service not just in numbers, but as the indispensable equal voices of a powerful choir. Full Article
der Saudi Leadership Must Focus on Innovation for the Future By www.chathamhouse.org Published On :: Wed, 16 Sep 2020 11:43:35 +0000 16 September 2020 Dr Neil Quilliam Associate Fellow, Middle East and North Africa Programme @NeilQuilliam1 A glorious year beckoned for Saudi Arabia, in leading the G20 and hosting the G20 Leaders' Summit in Riyadh in November. Instead, empowering its people and capitalizing on its youth should become the focus for an embattled leadership. 2020-09-16-Saudi-G20 Meeting of finance ministers and central bank governors of the G20 nations in the Saudi capital Riyadh on February 23, 2020. Photo by FAYEZ NURELDINE/AFP via Getty Images. The G20 summit in November was to be a moment when the world focused its attention on Saudi Arabia. As the leaders of the world's 20 largest economies came together for the first time in an Arab capital and presided over the world’s greatest challenges and opportunities, King Salman would have taken centre stage with his son and crown prince Mohammed bin Salman not far behind in the spotlight.However this will now be a virtual summit, and that is probably a blessing in disguise for the kingdom and its leadership which has not enjoyed a good year. It shares responsibility for crashing the price of oil, which, in conjunction with COVID-19, has brought the global economy to its knees. And it continues to be mired in the Yemen conflict, whereas its ally the United Arab Emirates (UAE) has, by and large, managed to extract itself while also seeking to rescue its reputation by signing a ‘peace deal’ with Israel.More recently, it has been forced to push back plans to host the next instalment of ‘Davos in Desert’ until 2021 and the crown prince’s flagship charity Misk is currently under review. The Public Investment Fund (PIF) made a wholly unsuccessful bid to secure a major stake in Newcastle United Football Club which brought an unfavourable ruling at the World Trade Organization (WTO) and a heap of damaging media attention.Squandered opportunityNothing washes away the stain of Jamal Khashoggi’s murder or the continuing imprisonment of women and men charged with being traitors. But in many ways, leading the G20 offered the Saudi leadership, especially Mohammed bin Salman, a chance to press reset and atone for some of the excesses of his more controversial policies, such as the war in Yemen and blockade of Qatar. But he appears to have squandered the opportunity so far and there are no signs that is about to change.Hosting the summit in Riyadh would have given Mohammed bin Salman an opportunity to try and recapture the heady days of 2018, when many of the world's leaders and even the media still viewed him as a force for good. He would have had a captive audience and, instead of staying away from Western capitals which he has chosen to do recently, he could have been feted by world leaders on his home turf. Moreover, the presidency agenda — empowering people, safeguarding the planet, and shaping new frontiers — would have lent itself to meaningful engagement on key policy issues.Although many analysts and commentators quite rightly argue that Riyadh’s focus on empowerment and safeguarding the planet is widely hypocritical given the kingdom has lurched further towards quashing any signs of opposition and remains highly dependent upon hydrocarbons, at least the ambitious goals of Vision 2030 ought to align with the G20 agenda. The goals of Vision 2030 remain aspirational and are far from ever being met, but there is synchronicity between the two agendas. In fact, the overview of Saudi Arabia’s G20 Presidency documentation states ‘the G20 agenda has a strong echo in the daily lives of the people in the Kingdom’.Saudi Arabia really needs to empower its people and capitalize upon its youth dividend but that requires, as so many have argued persuasively, long-term investment in education, training, and skills acquisition, and will not be achieved overnight. It needs strategic thinking, capacity-building, commitment, scope for course correction, and patience. There are no quick wins, no shortcuts.Safeguarding the planet is common to one and all but breaking a dependency upon hydrocarbons, diversifying its economy, and mitigating against the growing impact of climate change are all pressing issues Saudi Arabia needs to address. A failure to achieve these goals in a time-sensitive fashion poses a threat to the well-being of the kingdom and, in order to do so, it must empower its people and use technology wisely to advance the process. Saudi Arabia should be at the front of the pack, but is being surpassed by its neighbours and is in danger of being left way behind.With its wealth and youthful population, the kingdom can be at the cutting edge of shaping new frontiers. It can deploy its substantive funds to support its own innovators and — to borrow the jargon — create an ecosystem that not only offers Saudis an environment fostering creativity, but also one that draws talent into the kingdom.This does not mean investing in ‘white elephant’ projects that fail to spark the imagination of Saudis, or following the crowd to buy football clubs without rhyme or reason. It means gearing up to address everyday issues that preoccupy minds of Saudis, such as employment, housing, healthcare, and the well-being of family members. It is notable how the excitement of ‘bread and circus’ issues has abated and the focus moved once again towards family, faith and finance.The Saudi presidency of the G20 is in danger of passing by with a whimper and the November summit may now be unremarkable. This does not mean the hard work of the continuously active engagement groups will go unnoticed or to waste, but it does mean the photo-opportunity will be passed up and the joint statement garner less interest than usual.While it may feel like a lost opportunity for the kingdom and, in particular, Mohammed bin Salman, they should both breathe a sigh of relief. In many ways, they will be let off the hook by avoiding the direct scrutiny of the world’s media and human rights organizations. However, the crown prince could still seize the initiative given the spotlight will be on him, albeit from afar, and take bold steps towards resolving the thorny issues that have come to mar his pathway to power.

der Serum lipoprotein-derived fatty acids regulate hypoxia-inducible factor [Metabolism] By www.jbc.org Published On :: 2020-12-25T00:06:31-08:00 Oxygen regulates hypoxia-inducible factor (HIF) transcription factors to control cell metabolism, erythrogenesis, and angiogenesis. Whereas much has been elucidated about how oxygen regulates HIF, whether lipids affect HIF activity is un-known. Here, using cultured cells and two animal models, we demonstrate that lipoprotein-derived fatty acids are an independent regulator of HIF. Decreasing extracellular lipid supply inhibited HIF prolyl hydroxylation, leading to accumulation of the HIFα subunit of these heterodimeric transcription factors comparable with hypoxia with activation of downstream target genes. The addition of fatty acids to culture medium suppressed this signal, which required an intact mitochondrial respiratory chain. Mechanistically, fatty acids and oxygen are distinct signals integrated to control HIF activity. Finally, we observed lipid signaling to HIF and changes in target gene expression in developing zebrafish and adult mice, and this pathway operates in cancer cells from a range of tissues. This study identifies fatty acids as a physiological modulator of HIF, defining a mechanism for lipoprotein regulation that functions in parallel to oxygen. Full Article
der Why Ethiopia must close its political gender gap By www.chathamhouse.org Published On :: Fri, 29 Jul 2022 18:40:47 +0000 Why Ethiopia must close its political gender gap The World Today mhiggins.drupal 29 July 2022 Women urgently need to gain access to high office if the country hopes to survive, say Hilina Berhanu Degefa and Emebet Getachew. At the end of 2021, Prime Minister Abiy Ahmed’s government announced the formation of a three-year national dialogue to address Ethiopia’s political crisis, looking at the ongoing civil war and conflict, inflation, unemployment, drought and other urgent domestic issues. But, while efforts have been made to ensure the participation of women in this dialogue, it must be more than symbolic otherwise gaps in meaningful gender inclusion could have significant implications on the very survival of the country. One of the challenges for meaningful inclusion is that Ethiopia is a highly patriarchal society. Patriarchal norms and practices permeate all aspects of the country’s social, economic and political life. Women constitute over half of the Ethiopian population and represent 41 per cent of the national parliament. Nevertheless, most political parties, including those with liberal credentials, are exclusively governed by men, with women taking almost no part in key decision-making processes. As a result, women are relegated to the margins of political and economic activities. Prime Minister Abiy Ahmed won praise for appointing a gender-balanced cabinet in 2018. By 2021, women accounted for just 36 per cent of positions Though there has been little systematic study of the structural challenges faced by Ethiopian women in politics, women members of political parties encounter many barriers, including political violence, male-coded norms and sexist discourses across Ethiopian society. The nature and scale of political violence perpetrated against women is particularly disempowering and affects their ability to participate in political spaces. While attitudes to gender equality, sexual violence and gender discrimination are often trivialized, they remain ever-present threats in women’s lives. As late as 2016, a significant minority of men still believed wife-beating to be justified in certain situations. Even when women overcome social pressure to pursue their political ambitions, patriarchal views and practices within political party structures about the role of women significantly undermine their active participation and engagement. The political space is even more inaccessible to women with disabilities and in conflict and climate-related crises such as among internally displaced people and in pastoral communities. Male-coded norms ingrained at both party and community levels remain a significant concern. Specifically, sex in exchange for candidacy, inconsiderate working schedules affecting women with children and denial of access to equal information and financial resources are frequently reported as major internal hurdles among political parties. Closing the gender gap could offer Ethiopia a new beginning Many political initiatives designed to tackle these gender imbalances often have been driven by short-term political considerations without proper gender-gap assessment and policy analysis. In most cases, the authorities have viewed gender-targeted reforms as acts of benevolence, dispensed by the government, without adopting the legal and financial measures necessary to ensure sustainability and impact. Take, for example, Abiy’s appointment of a 50:50 gender-balanced cabinet in 2018. At the time, much was made about its transformative potential, with the prime minister attracting widespread global approval. Yet, a cabinet reshuffle in 2021 reduced female representation to 36.3 per cent, with far less scrutiny or accountability. The proposed national dialogue presents an ideal opportunity for Ethiopian women to begin reshaping attitudes This indicates that gender equality in Ethiopia is not considered a priority but rather an endeavour for more opportune, ‘stable’ times. Without thorough measures that create the conditions for real change, the aspiration of having a gender-balanced cabinet will always be challenging to translate into lasting equal representation. The proposed national dialogue presents an ideal opportunity for Ethiopian women to begin reshaping attitudes and closing the gender gap through their inclusion and participation in the political process. To do so, three issues must be addressed. First, the varying rights of women need to be consolidated, including on identity, constitutional reform and economic issues . Second, gender equality considerations must be absorbed into mainstream political discourse at all levels. Third, the experiences of women in the recent war, other ongoing conflicts and past and lingering legacies of political violence targeting women from specific communities, must be acknowledged and remedied. If Ethiopia is indeed serious about addressing its asymmetric gender power dynamics, this national dialogue provides an excellent opportunity to begin the process. Genuine participation of women as independent actors, with their own agency, could offer Ethiopia a new beginning. Full Article

In Tigray, the world’s largest armed conflict rages between Ethiopian federal government troops and the Tigray Defence Forces. With estimates placing those killed in the fighting at 600,000, how did Ethiopia, one of Africa’s great success stories, descend into civil war, and what hopes are there for recent peace initiatives? Meanwhile in Ukraine, all eyes are on Zaporizhzhia, as Europe’s largest nuclear plant continues to be occupied by Russian forces. With fresh reports of explosions near the reactors, how is the international community responding? Finally, what role does Turkey, a middle power country with great power ambitions, play in both conflicts?

der Human pancreatic cancer cells under nutrient deprivation are vulnerable to redox system inhibition [Cell Biology] By www.jbc.org Published On :: 2020-12-04T00:06:05-08:00 Large regions in tumor tissues, particularly pancreatic cancer, are hypoxic and nutrient-deprived because of unregulated cell growth and insufficient vascular supply. Certain cancer cells, such as those inside a tumor, can tolerate these severe conditions and survive for prolonged periods. We hypothesized that small molecular agents, which can preferentially reduce cancer cell survival under nutrient-deprived conditions, could function as anticancer drugs. In this study, we constructed a high-throughput screening system to identify such small molecules and screened chemical libraries and microbial culture extracts. We were able to determine that some small molecular compounds, such as penicillic acid, papyracillic acid, and auranofin, exhibit preferential cytotoxicity to human pancreatic cancer cells under nutrient-deprived compared with nutrient-sufficient conditions. Further analysis revealed that these compounds target to redox systems such as GSH and thioredoxin and induce accumulation of reactive oxygen species in nutrient-deprived cancer cells, potentially contributing to apoptosis under nutrient-deprived conditions. Nutrient-deficient cancer cells are often deficient in GSH; thus, they are susceptible to redox system inhibitors. Targeting redox systems might be an attractive therapeutic strategy under nutrient-deprived conditions of the tumor microenvironment. Full Article
der Iron-mediated degradation of ribosomes under oxidative stress is attenuated by manganese [Cell Biology] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 Protein biosynthesis is fundamental to cellular life and requires the efficient functioning of the translational machinery. At the center of this machinery is the ribosome, a ribonucleoprotein complex that depends heavily on Mg2+ for structure. Recent work has indicated that other metal cations can substitute for Mg2+, raising questions about the role different metals may play in the maintenance of the ribosome under oxidative stress conditions. Here, we assess ribosomal integrity following oxidative stress both in vitro and in cells to elucidate details of the interactions between Fe2+ and the ribosome and identify Mn2+ as a factor capable of attenuating oxidant-induced Fe2+-mediated degradation of rRNA. We report that Fe2+ promotes degradation of all rRNA species of the yeast ribosome and that it is bound directly to RNA molecules. Furthermore, we demonstrate that Mn2+ competes with Fe2+ for rRNA-binding sites and that protection of ribosomes from Fe2+-mediated rRNA hydrolysis correlates with the restoration of cell viability. Our data, therefore, suggest a relationship between these two transition metals in controlling ribosome stability under oxidative stress. Full Article

der Lipid Conformational Order and the Etiology of Cataract and Dry Eye [Thematic Reviews] By www.jlr.org Published On :: 2020-06-18T14:30:29-07:00 Lens and tear film lipids are as unique as the systems they reside in. The major lipid of the human lens is dihydrosphingomylein, found in quantity only in the lens. The lens contains a cholesterol to phospholipid molar ratio as high as 10:1, more than anywhere in the body. Lens lipids contribute to maintaining lens clarity, and alterations in lens lipid composition due to age are likely to contribute to cataract. Lens lipid composition reflects adaptations to the unique characteristics of the lens: no turnover of lens lipids or proteins; the lowest amount of oxygen than any other tissue and contains almost no intracellular organelles. The tear film lipid layer (TFLL) is also unique. The TFLL is a thin, 100 nm layer of lipid on the surface of tears covering the cornea that contributes to tear film stability. The major lipids of the TFLL are wax esters and cholesterol esters that are not found in the lens. The hydrocarbon chains associated with the esters are longer than those found anywhere in the body, as long as 32 carbons, and many are branched. Changes in the composition and structure of the 30,000 different moieties of TFLL contribute to the instability of tears. The focus of the current review is how spectroscopy has been used to elucidate the relationships between lipid composition, conformational order and function and the etiology of cataract and dry eye.

der Update on LIPID MAPS classification, nomenclature, and shorthand notation for MS-derived lipid structures [Special Reports] By www.jlr.org Published On :: 2020-12-01T00:05:39-08:00 A comprehensive and standardized system to report lipid structures analyzed by MS is essential for the communication and storage of lipidomics data. Herein, an update on both the LIPID MAPS classification system and shorthand notation of lipid structures is presented for lipid categories Fatty Acyls (FA), Glycerolipids (GL), Glycerophospholipids (GP), Sphingolipids (SP), and Sterols (ST). With its major changes, i.e., annotation of ring double bond equivalents and number of oxygens, the updated shorthand notation facilitates reporting of newly delineated oxygenated lipid species as well. For standardized reporting in lipidomics, the hierarchical architecture of shorthand notation reflects the diverse structural resolution powers provided by mass spectrometric assays. Moreover, shorthand notation is expanded beyond mammalian phyla to lipids from plant and yeast phyla. Finally, annotation of atoms is included for the use of stable isotope-labeled compounds in metabolic labeling experiments or as internal standards. This update on lipid classification, nomenclature, and shorthand annotation for lipid mass spectra is considered a standard for lipid data presentation. Full Article
der A Comprehensive Gender-related Secretome of Plasmodium berghei Sexual Stages [Research] By www.mcponline.org Published On :: 2020-12-01T00:05:33-08:00 Plasmodium, the malaria parasite, undergoes a complex life cycle alternating between a vertebrate host and a mosquito vector of the genus Anopheles. In red blood cells of the vertebrate host, Plasmodium multiplies asexually or differentiates into gamete precursors, the male and female gametocytes, responsible for parasite transmission. Sexual stage maturation occurs in the midgut of the mosquito vector, where male and female gametes egress from the host erythrocytes to fuse and form a zygote. Gamete egress entails the successive rupture of two membranes surrounding the parasite, the parasitophorous vacuole membrane and the erythrocyte plasma membrane. In this study, we used the rodent model parasite Plasmodium berghei to design a label-free quantitative proteomic approach aimed at identifying gender-related proteins differentially released/secreted by purified mature gametocytes when activated to form gametes. We compared the abundance of molecules secreted by wild type gametocytes of both genders with that of a transgenic line defective in male gamete maturation and egress. This enabled us to provide a comprehensive data set of egress-related molecules and their gender specificity. Using specific antibodies, we validated eleven candidate molecules, predicted as either gender-specific or common to both male and female gametocytes. All of them localize to punctuate, vesicle-like structures that relocate to cell periphery upon activation, but only three of them localize to the gametocyte-specific secretory vesicles named osmiophilic bodies. Our results confirm that the egress process involves a tightly coordinated secretory apparatus that includes different types of vesicles and may put the basis for functional studies aimed at designing novel transmission-blocking molecules.
