orm A comprehensive evaluation of a typical plant telomeric G-quadruplex (G4) DNA reveals the dynamics of G4 formation, rearrangement, and unfolding [Plant Biology] By www.jbc.org Published On :: 2020-04-17T00:06:05-07:00 Telomeres are specific nucleoprotein structures that are located at the ends of linear eukaryotic chromosomes and play crucial roles in genomic stability. Telomere DNA consists of simple repeats of a short G-rich sequence: TTAGGG in mammals and TTTAGGG in most plants. In recent years, the mammalian telomeric G-rich repeats have been shown to form G-quadruplex (G4) structures, which are crucial for modulating telomere functions. Surprisingly, even though plant telomeres are essential for plant growth, development, and environmental adaptions, only few reports exist on plant telomeric G4 DNA (pTG4). Here, using bulk and single-molecule assays, including CD spectroscopy, and single-molecule FRET approaches, we comprehensively characterized the structure and dynamics of a typical plant telomeric sequence, d[GGG(TTTAGGG)3]. We found that this sequence can fold into mixed G4s in potassium, including parallel and antiparallel structures. We also directly detected intermediate dynamic transitions, including G-hairpin, parallel G-triplex, and antiparallel G-triplex structures. Moreover, we observed that pTG4 is unfolded by the AtRecQ2 helicase but not by AtRecQ3. The results of our work shed light on our understanding about the existence, topological structures, stability, intermediates, unwinding, and functions of pTG4. Full Article
orm Biochemical and structural insights into how amino acids regulate pyruvate kinase muscle isoform 2 [Enzymology] By www.jbc.org Published On :: 2020-04-17T00:06:05-07:00 Pyruvate kinase muscle isoform 2 (PKM2) is a key glycolytic enzyme involved in ATP generation and critical for cancer metabolism. PKM2 is expressed in many human cancers and is regulated by complex mechanisms that promote tumor growth and proliferation. Therefore, it is considered an attractive therapeutic target for modulating tumor metabolism. Various stimuli allosterically regulate PKM2 by cycling it between highly active and less active states. Several small molecules activate PKM2 by binding to its intersubunit interface. Serine and cysteine serve as an activator and inhibitor of PKM2, respectively, by binding to its amino acid (AA)-binding pocket, which therefore represents a potential druggable site. Despite binding similarly to PKM2, how cysteine and serine differentially regulate this enzyme remains elusive. Using kinetic analyses, fluorescence binding, X-ray crystallography, and gel filtration experiments with asparagine, aspartate, and valine as PKM2 ligands, we examined whether the differences in the side-chain polarity of these AAs trigger distinct allosteric responses in PKM2. We found that Asn (polar) and Asp (charged) activate PKM2 and that Val (hydrophobic) inhibits it. The results also indicate that both Asn and Asp can restore the activity of Val-inhibited PKM2. AA-bound crystal structures of PKM2 displayed distinctive interactions within the binding pocket, causing unique allosteric effects in the enzyme. These structure-function analyses of AA-mediated PKM2 regulation shed light on the chemical requirements in the development of mechanism-based small-molecule modulators targeting the AA-binding pocket of PKM2 and provide broader insights into the regulatory mechanisms of complex allosteric enzymes.

orm Mechanistic insights explain the transforming potential of the T507K substitution in the protein-tyrosine phosphatase SHP2 [Signal Transduction] By www.jbc.org Published On :: 2020-05-01T00:06:09-07:00 The protein-tyrosine phosphatase SHP2 is an allosteric enzyme critical for cellular events downstream of growth factor receptors. Mutations in the SHP2 gene have been linked to many different types of human diseases, including developmental disorders, leukemia, and solid tumors. Unlike most SHP2-activating mutations, the T507K substitution in SHP2 is unique in that it exhibits oncogenic Ras-like transforming activity. However, the biochemical basis of how the SHP2/T507K variant elicits transformation remains unclear. By combining kinetic and biophysical methods, X-ray crystallography, and molecular modeling, as well as using cell biology approaches, here we uncovered that the T507K substitution alters both SHP2 substrate specificity and its allosteric regulatory mechanism. We found that although SHP2/T507K exists in the closed, autoinhibited conformation similar to the WT enzyme, the interactions between its N-SH2 and protein-tyrosine phosphatase domains are weakened such that SHP2/T507K possesses a higher affinity for the scaffolding protein Grb2-associated binding protein 1 (Gab1). We also discovered that the T507K substitution alters the structure of the SHP2 active site, resulting in a change in SHP2 substrate preference for Sprouty1, a known negative regulator of Ras signaling and a potential tumor suppressor. Our results suggest that SHP2/T507K's shift in substrate specificity coupled with its preferential association of SHP2/T507K with Gab1 enable the mutant SHP2 to more efficiently dephosphorylate Sprouty1 at pTyr-53. This dephosphorylation hyperactivates Ras signaling, which is likely responsible for SHP2/T507K's Ras-like transforming activity. Full Article
orm Glucose availability but not changes in pancreatic hormones sensitizes hepatic AMPK activity during nutritional transition in rodents [Metabolism] By www.jbc.org Published On :: 2020-05-01T00:06:09-07:00 The cellular energy sensor AMP-activated protein kinase (AMPK) is a metabolic regulator that mediates adaptation to nutritional variations to maintain a proper energy balance in cells. We show here that suckling-weaning and fasting-refeeding transitions in rodents are associated with changes in AMPK activation and the cellular energy state in the liver. These nutritional transitions were characterized by a metabolic switch from lipid to glucose utilization, orchestrated by modifications in glucose levels and the glucagon/insulin ratio in the bloodstream. We therefore investigated the respective roles of glucose and pancreatic hormones on AMPK activation in mouse primary hepatocytes. We found that glucose starvation transiently activates AMPK, whereas changes in glucagon and insulin levels had no impact on AMPK. Challenge of hepatocytes with metformin-induced metabolic stress strengthened both AMPK activation and cellular energy depletion under limited-glucose conditions, whereas neither glucagon nor insulin altered AMPK activation. Although both insulin and glucagon induced AMPKα phosphorylation at its Ser485/491 residue, they did not affect its activity. Finally, the decrease in cellular ATP levels in response to an energy stress was additionally exacerbated under fasting conditions and by AMPK deficiency in hepatocytes, revealing metabolic inflexibility and emphasizing the importance of AMPK for maintaining hepatic energy charge. Our results suggest that nutritional changes (i.e. glucose availability), rather than the related hormonal changes (i.e. the glucagon/insulin ratio), sensitize AMPK activation to the energetic stress induced by the dietary transition during fasting. This effect is critical for preserving the cellular energy state in the liver. Full Article

Kaiser Chair in International Law, University of OklahomaBarbora Bukovská, Senior Director for Law and Policy, Article 19Kate Jones, Director, Diplomatic Studies Programme, University of OxfordChair: Harriet Moynihan, Associate Fellow, International Law Programme, Chatham House Register Interest Cyber operations are increasingly used by political parties, their supporters and foreign states to influence electorates – from algorithms promoting specific messages to micro-targeting based on personal data and the creation of filter bubbles. The risks of digital tools spreading disinformation and polarizing debate, as opposed to deepening democratic engagement, have been highlighted by concerns over cyber interference in the UK’s Brexit referendum, the 2016 US presidential elections and in Ukraine. While some governments are adopting legislation in an attempt to address some of these issues, for example Germany’s ‘NetzDG’ law and France’s ‘Law against the manipulation of information’, other countries have proposed an independent regulator as in the case of the UK’s Online Harms white paper. Meanwhile, the digital platforms, as the curators of content, are under increasing pressure to take their own measures to address data mining and manipulation in the context of elections. How do international human rights standards, for example on freedom of thought, expression and privacy, guide the use of digital technology in the electoral context? What practical steps can governments and technology actors take to ensure policies, laws and practices are in line with these fundamental standards? And with a general election looming in the UK, will these steps come soon enough? This event brings together a wide range of stakeholders including civil society, the tech sector, legal experts and government, coincides with the publication of a Chatham House research paper on disinformation, elections and the human rights framework.

Photo: Getty Images. SummaryOnline political campaigning techniques are distorting our democratic political processes. These techniques include the creation of disinformation and divisive content; exploiting digital platforms’ algorithms, and using bots, cyborgs and fake accounts to distribute this content; maximizing influence through harnessing emotional responses such as anger and disgust; and micro-targeting on the basis of collated personal data and sophisticated psychological profiling techniques. Some state authorities distort political debate by restricting, filtering, shutting down or censoring online networks.Such techniques have outpaced regulatory initiatives and, save in egregious cases such as shutdown of networks, there is no international consensus on how they should be tackled. Digital platforms, driven by their commercial impetus to encourage users to spend as long as possible on them and to attract advertisers, may provide an environment conducive to manipulative techniques.International human rights law, with its careful calibrations designed to protect individuals from abuse of power by authority, provides a normative framework that should underpin responses to online disinformation and distortion of political debate. Contrary to popular view, it does not entail that there should be no control of the online environment; rather, controls should balance the interests at stake appropriately.The rights to freedom of thought and opinion are critical to delimiting the appropriate boundary between legitimate influence and illegitimate manipulation. When digital platforms exploit decision-making biases in prioritizing bad news and divisive, emotion-arousing information, they may be breaching these rights. States and digital platforms should consider structural changes to digital platforms to ensure that methods of online political discourse respect personal agency and prevent the use of sophisticated manipulative techniques.The right to privacy includes a right to choose not to divulge your personal information, and a right to opt out of trading in and profiling on the basis of your personal data. Current practices in collecting, trading and using extensive personal data to ‘micro-target’ voters without their knowledge are not consistent with this right. Significant changes are needed.Data protection laws should be implemented robustly, and should not legitimate extensive harvesting of personal data on the basis of either notional ‘consent’ or the data handler’s commercial interests. The right to privacy should be embedded in technological design (such as by allowing the user to access all information held on them at the click of a button); and political parties should be transparent in their collection and use of personal data, and in their targeting of messages. Arguably, the value of personal data should be shared with the individuals from whom it derives.The rules on the boundaries of permissible content online should be set by states, and should be consistent with the right to freedom of expression. Digital platforms have had to rapidly develop policies on retention or removal of content, but those policies do not necessarily reflect the right to freedom of expression, and platforms are currently not well placed to take account of the public interest. Platforms should be far more transparent in their content regulation policies and decision-making, and should develop frameworks enabling efficient, fair, consistent internal complaints and content monitoring processes. Expertise on international human rights law should be integral to their systems.The right to participate in public affairs and to vote includes the right to engage in public debate. States and digital platforms should ensure an environment in which all can participate in debate online and are not discouraged from standing for election, from participating or from voting by online threats or abuse.

Photo: Getty Images. EU and US cooperation on tackling disinformation needs to be grounded in an international human rights framework in order to bridge the differences of both parties and include other countries facing this challenge.The disinformation debate needs to be reformulated to cover systemic issues rather than merely technical or security concerns. A lag in regulatory development has led to systemic vulnerabilities. In this context, policymakers need to push for more evidence-based analysis, which is only attainable if technology companies engage in honest debate and allow meaningful access to data – as determined by government appointed researchers rather than the companies themselves – taking into account and respecting users’ privacy.Data governance needs to be the focus of attempts to tackle disinformation. Data’s implications for information, market and power asymmetries, feed into and exacerbate the problem.Policymakers should focus on regulating the distribution of online content rather than the subject matter itself, which may have implications for freedom of speech.Disinformation is mainly the result of inefficient gatekeeping of highly extractive digital companies. The old gatekeepers, journalists and their respective regulators, need to be actively engaged in devising the new regulatory framework.Legacy media need to urgently consider the issue of ‘strategic silence’ and avoid being co-opted by political actors aiming to manipulate the accelerated, reactive news cycle by engaging in divisive ‘clickbait’ rhetoric verging on disinformation and propaganda. When strategic silence is not an option, contextual analysis is fundamental. The EU delegation should assist the coordination of EU–US efforts to tackle disinformation by drawing on the work and expertise at the G7 Rapid Response Mechanism (RRM), the Transatlantic Commission on Election Integrity (TCEI), the European Centre of Excellence for Countering Hybrid Threats (Hybrid CoE), the High-level Panel on Digital Cooperation, and work with the International Telecommunication Union (ITU) to foster a long-term interdisciplinary forum to harness technological innovation to protect and support democracy from threats such as disinformation.The EU and US must avoid rushed regulation that may condone enhanced surveillance or vilify journalism that scrutinizes those in power in the name of security.

orm Prospects for Reforming Libya’s Economic Governance: Ways Forward By feedproxy.google.com Published On :: Mon, 27 Jan 2020 15:45:02 +0000 Invitation Only Research Event 6 February 2020 - 10:30am to 12:30pm Chatham House | 10 St James's Square | London | SW1Y 4LE Event participants Jason Pack, Non-Resident Fellow, Middle East InstituteTim Eaton, Senior Research Fellow, Middle East and North Africa Programme, Chatham HouseChair: Elham Saudi, Director, Lawyers for Justice Libya There is a broad consensus that Libya’s rentier, patronage-based system of governance is a driver, and not only a symptom, of Libya’s continuing conflict. The dysfunction of Libya’s economic system of governance has been exacerbated by the governance split that has prevailed since 2014 whereby rival administrations of state institutions have emerged. Despite these challenges, a system of economic interdependence, whereby forces aligned with Field Marshal Haftar control much of the oil and gas infrastructure and the UN-backed Government of National Accord controls the means of financial distribution, has largely prevailed. Yet, at the time of writing, this is under threat: a damaging oil blockade is being implemented by forces aligned with Haftar and those state institutions that do function on a national basis are finding it increasingly difficult to avoid being dragged into the conflict.This roundtable will bring together analysts and policymakers to discuss these dynamics and look at possible remedies. Jason Pack, non-resident fellow at the Middle East Institute, will present the findings of his latest paper on the issue which recommends the formation of 'a Libyan-requested and Libyan-led International Financial Commission vested with the requisite authorities to completely restructure the economy.' Tim Eaton, who has been leading Chatham House’s work on Libya’s conflict economy, supporting UNSMIL’s efforts in this field, will act as respondent.Attendance at this event is by invitation only.

orm Why is it So Hard for Iraq to Form A Government?

Photo by Fariq Faraj Mahmood/Anadolu Agency via Getty Images. On April 9, Iraqi President Barham Salih gathered the Shia, Kurdish and Sunni political blocs at the presidential palace to task head of intelligence Mustafa al-Kadhimi with forming a government.Kadhimi is the third prime minister-designate assigned since Prime Minister Adil abd al-Mehdi resigned in November, in the wake of mass protests against government corruption and the country’s ethno-sectarian based political system.Kadhimi’s two predecessors, Muhammad Tawfiq Allawi and Adnan al-Zurfi, both failed to form a government. This third attempt came as Iraq struggles with repeated crises since October 2019, when the government began responding with deadly force to large-scale mass protests, killing more than 600 and injuring tens of thousands.In January, the assassination of Qasem Soleimani escalated tensions between the United States and Iran, with Iraq stuck in the middle and becoming the home for regular tit-for-tat attacks. The Islamic State — never completely defeated — took advantage of these crises and increased its attacks in disputed territories.The outbreak of COVID-19 challenges the country’s fragile public health sector, while the decline in the price of oil will make it harder for leaders to pay the public salaries that keep the system (and patronage) moving.What does the delay in forming a government amid multiple crises mean for the post-2003 Iraqi political system? Iraq’s post-2003 political system is designed to withstand crisis. Over the years, political parties reflecting the country’s ethnic and sectarian divides have had a tacit understanding that crises represent a risk to their collective interests. These elite stakeholders have together weathered civil war, insurgency and multiple protests — despite deep conflicts with one another.For instance, in September 2018 protesters attacked most major political party headquarters and the Iranian consulate in Basra, and authorities killed some 20 protesters.Since the May election of that year, the fragmented Shia elite had been unable to even declare which side has the largest parliamentary bloc, let alone decide on a government.But after the September crisis, the previously gridlocked parties swiftly came together to form an “understanding” that pushed through the impasse leading to the Mehdi government. In 2020, however, Iraq’s political parties were slower to come back together despite the multiple crises — far greater than 2018. The system is less able to swiftly fix itself, based primarily on the fragmentation of the elite — and their determination to prevent any challenge to their rule.Why did the two prior attempts fail? The two previous prime minister-designates each fell short for different reasons. When I met Allawi in February at the prime minister’s guesthouse in Baghdad, he was very clearly convinced that his mandate was to sideline the parties.He hoped that simply choosing technocratic ministers outside the elite pact, with the support of Moqtada al-Sadr behind him, would garner support from protesters and the disillusioned public. He failed, however, because his cabinet had to go through parliament and the parties rejected what they saw a threat to the elite pact and the system.Zurfi similarly failed after being directly appointed in March by Salih after the Shia parties failed to come up with a candidate. From the beginning, then, Zurfi faced challenges because parties were not in agreement. He attempted to directly confront his opposition, and spoke out against Iranian influence in Iraq. As a result, Zurfi was unable to even get to parliament with his proposed cabinet, as the Shia parties got back together to bring him down.The failure of both strategies — Allawi attempting to work outside the elite party system and Zurfi trying to target certain parties — reveals tensions in Iraq’s political system. This fragmentation strains the parties’ ability to swiftly unite, and the system’s ability to withstand crises.The endemic problems are a consequence of fragmentation, including the failure following the 2018 elections to declare governing parliamentary bloc. Moreover, after that election, newcomers into the political system (two-thirds of the MPs are serving their first term) are increasingly making their own demands and less willing to blindly toe party lines.Can Kadhimi overcome the impasse?Kadhimi’s appointment as prime minister-designate nonetheless is on shaky foundations. His appointment had previously faced a veto from Iran and its allied groups which make up the Fateh bloc. Kataeb Hezbollah, an armed group close to Iran and linked to the Popular Mobilization Units, issued a statement accusing Kadhimi with blood on his hands for the deaths of Soleimani and Abu Mahdi al-Muhandis.Many Fateh bloc members had for months vetoed Kadhimi’s name due to this allegation. Immediately before Kadhimi addressed the nation for the first time, Iraqi state television broadcast a prerecorded statement by PMU (and Fateh) leader Qais al-Khazali, who had also previously accused Kadhimi of spying for the Americans and being complicit in the two killings.Khazali, who commands the second-largest party within Fateh, accepted the party line to back Kadhimi but came out with his own conditions on television. However, the concerns about the COVID-19 crisis and the collapse of the price of oil finally brought all sides to compromise — a design of the political system.Kadhimi has signalled he will play by the old rules with these stakeholders. Because of the magnitude of these simultaneous crises, Iraqi politics is moving back to the post-2003 norm. The ethno-sectarian based political system is geared to weather such existential crises more than it is to handling day-to-day governance. Despite the notion of “post-sectarianism” in Iraq, this system is based on ethno-sectarian political party compromise.In his television address, Khazali, who had previously attempted to move away from sectarian language, explained that the process of selecting a prime minister is reserved to the Shia, who have the right as the majority, and not to Salih, a Kurd.Over the years Kadhimi has expressed an admiration of the bravery of the protesters and of the importance of civil society. Many Iraqi civil society activists owe their lives to the work of the former intelligence chief. However, he has also been part of the same system that has violently suppressed protesters.As the compromise prime minister-designate, he will find it difficult to transform his country as long as he plays by the rules of post-2003 Iraq — an irony not lost on the protesters who immediately rejected the candidacy of a man whom until recently many protesters had supported.This article was originally published in The Washington Post Full Article
orm Soundscapes of war: the audio-visual performance of war by Shi'a militias in Iraq and Syria By feedproxy.google.com Published On :: Thu, 07 May 2020 09:16:54 +0000 7 May 2020 , Volume 96, Number 3 Helle Malmvig Read online This article sets out to bring sound and music to the field of visual studies in International Relations. It argues that IR largely has approached the visual field as if it was without sound; neglecting how audial landscapes frame and direct our interpretation of moving imagery. Sound and music contribute to making imagery intelligible to us, we ‘hear the pictures’ often without noticing. The audial can for instance articulate a visual absence, or blast visual signs, bring out certain emotional stages or subjects’ inner life. Audial frames steer us in distinct directions, they can mute the cries of the wounded in war, or amplify the sounds of joy of soldiers shooting in the air. To bring the audial and the visual analytically and empirically together, the article therefore proposes four key analytical themes: 1) the audial–visual frame, 2) point of view/point of audition, 3) modes of audio-visual synchronization and 4) aesthetics moods. These are applied to a study of ‘war music videos’ in Iraq and Syria made and circulated by Shi'a militias currently fighting there. Such war music videos, it is suggested, are not just artefacts of popular culture, but have become integral parts of how warfare is practiced today, and one that is shared by soldiers in the US and Europe. War music videos are performing war, just as they shape how war is known by spectators and participants alike. Full Article
orm Quantitative test-retest measurement of 68Ga-PSMA-HBED-CC (PSMA-11) in tumor and normal tissue By jnm.snmjournals.org Published On :: 2019-12-05T10:37:42-08:00 The PET radiotracer 68Ga-PSMA-HBED-CC (68Ga-PSMA-11) shows potential as an imaging biomarker for recurrent and metastatic prostate cancer. The purpose of this study was to determine repeatability of 68Ga-PSMA-HBED-CC in a test-retest trial in subjects with metastatic prostate adenocarcinoma. Methods: Subjects with metastatic prostate cancer underwent two PET/CT scans with 68Ga-PSMA-HBED-CC within 14 days (mean 6 ± 4 d). Lesions in bone, nodes, prostate/bed, and visceral organs as well as representative normal tissues (salivary glands and spleen) were segmented separately by two readers. Absolute and percent differences in SUVmax and SUVmean were calculated for all test-retest regions. Repeatability was assessed using percentage difference, within-subject coefficient of variation (wCV), repeatability coefficient (RC), and Bland-Altman analysis. Results: 18 subjects were evaluated, 16 of which demonstrated local or metastatic disease on 68Ga-PSMA-HBED-CC PET/CT. A total of 136 lesions were segmented in bone (n = 99), nodes (n = 27), prostate/bed (n = 7), and viscera (n = 3). The wCV for SUVmax was 11.7% for bone lesions and 13.7% for nodes. The RC was ±32.5% SUVmax for bone lesions and ±37.9% SUVmax for nodal lesions, meaning 95% of the normal variability between two measurements will be within these numbers, so larger differences are likely attributable to true biological changes in tumor rather than normal physiologic or measurement variability. wCV in the salivary glands and spleen was 8.9% and 10.7% SUVmean, respectively. Conclusion: Repeatability measurements for PET/CT test-retest with 68Ga-PSMA-HBED-CC show a wCV 12-14% SUVmax and RC ±33-38% SUVmax in bone and nodal lesions. These estimates are an important aspect of 68Ga-PSMA-HBED-CC as a quantitative imaging biomarker. These estimates are similar to those reported for 18F-FDG, suggesting that 68Ga-PSMA-HBED-CC PET/CT may be useful in monitoring response to therapy. Full Article
