Deletion of fatty acid transport protein 2 (FATP2) in the mouse liver changes the metabolic landscape by increasing the expression of PPAR{alpha}-regulated genes [Lipids]

Fatty acid transport protein 2 (FATP2) is highly expressed in the liver, small intestine, and kidney, where it functions in both the transport of exogenous long-chain fatty acids and the activation of very-long-chain fatty acids. Here, using a murine model, we investigated the phenotypic impacts of deleting FATP2, followed by a transcriptomic analysis using unbiased RNA-Seq to identify concomitant changes in the liver transcriptome. WT and FATP2-null (Fatp2−/−) mice (5 weeks) were maintained on a standard chow diet for 6 weeks. The Fatp2−/− mice had reduced weight gain, lowered serum triglyceride, and increased serum cholesterol levels and attenuated dietary fatty acid absorption. Transcriptomic analysis of the liver revealed 258 differentially expressed genes in male Fatp2−/− mice and a total of 91 in female Fatp2−/− mice. These genes mapped to the following gene ontology categories: fatty acid degradation, peroxisome biogenesis, fatty acid synthesis, and retinol and arachidonic acid metabolism. Targeted RT-quantitative PCR verified the altered expression of selected genes. Of note, most of the genes with increased expression were known to be regulated by peroxisome proliferator–activated receptor α (PPARα), suggesting that FATP2 activity is linked to a PPARα-specific proximal ligand. Targeted metabolomic experiments in the Fatp2−/− liver revealed increases of total C16:0, C16:1, and C18:1 fatty acids; increases in lipoxin A4 and prostaglandin J2; and a decrease in 20-hydroxyeicosatetraenoic acid. We conclude that the expression of FATP2 in the liver broadly affects the metabolic landscape through PPARα, indicating that FATP2 provides an important role in liver lipid metabolism through its transport or activation activities.

Coronavirus: All Citizens Need an Income Support

16 March 2020

Jim O'Neill

Chair, Chatham House
We cannot expect policies such as the dramatic monetary steps announced by the Federal Reserve Board and others like it, to end this crisis. A People's Quantitative Easing (QE) could be the answer.

2020-03-16-coronavirus-delivery.jpg

Linked to the call for a global response to the Covid-19 pandemic that I, Robin Niblett and Creon Butler have outlined, the case for a specific dramatic economic policy gesture from many policymakers in large economies is prescient.

It may not be warranted from all G20 nations, although given the uncertainties, and the desire to show collective initiative, I think it should be G20 driven and inclusive.

We need some sort of income support for all our citizens, whether employees or employers. Perhaps one might call it a truly People’s QE (quantitative easing).

Against the background of the previous economic crisis from 2008, and the apparent difficulties that more traditional forms of economic stimulus have faced in trying to help their economies and their people - especially against a background of low wage growth, and both actual, and perception of rising inequality - other ideas have emerged.

Central banks printing money

Both modern monetary theory (MMT) and universal basic income (UBI) essentially owe their roots to the judgement that conventional economic policies have not been helping.

At the core of these views is the notion of giving money to people, especially lower income people, directly paid for by our central banks printing money. Until recently, I found myself having very little sympathy with these views but, as a result of COVID-19, I have changed my mind.

This crisis is extraordinary in so far as it is both a colossal demand shock and an even bigger colossal supply shock. The crisis epicentre has shifted from China - and perhaps the rest of Asia - to Europe and the United States. We cannot expect policies, however unconventional by modern times, such as the dramatic monetary steps announced by the Federal Reserve Board and others like it, to put a floor under this crisis.

We are consciously asking our people to stop going out, stop travelling, not go to their offices - in essence, curtailing all forms of normal economic life. The only ones not impacted are those who entirely work through cyberspace. But even they have to buy some forms of consumer goods such as food and, even if they order online, someone has to deliver it.

As a result, markets are, correctly, worrying about a collapse of economic activity and, with it, a collapse of companies, not just their earnings. Expansion of central bank balance sheets is not going to do anything to help that, unless it is just banks we are again worried about saving.

What is needed in current circumstances, are steps to make each of us believe with high confidence that, if we take the advice from our medical experts, especially if we self-isolate and deliberately restrict our personal incomes, then we will have this made good by our governments. In essence, we need smart, persuasive People’s QE.

Having discussed the idea with a couple of economic experts, there are considerable difficulties with moving beyond the simple concept. In the US for example, I believe the Federal Reserve is legally constrained from pursuing a direct transfer of cash to individuals or companies, and this may be true elsewhere.

But this is easily surmounted by fiscal authorities issuing a special bond, the proceeds of which could be transferred to individuals and business owners. And central banks could easily finance such bonds.

It is also the case that such a step would encroach on the perception and actuality of central bank independence, but I would be among those that argue central banks can only operate this independence if done wisely. Others will argue that, in the spirit of the equality debate, any income support should be targeted towards those on very low incomes, while higher earners or large businesses, shouldn’t be given any, or very little.

I can sympathise with such spirit, but this also ignores the centrality of this particular economic shock. All of our cafes and restaurants, and many of our airlines, and such are at genuine risk of not being able to survive, and these organisations are considerable employers of people on income.

It is also the case that time is of the essence, and we need our policymakers to act as soon as possible, otherwise the transmission mechanisms, including those about the permanent operation of our post World War 2 form of life may be challenged.

We need some kind of smart People’s QE now.

Lipid-tuned Zinc Transport Activity of Human ZnT8 Protein Correlates with Risk for Type-2 Diabetes [Molecular Bases of Disease]

Zinc is a critical element for insulin storage in the secretory granules of pancreatic beta cells. The islet-specific zinc transporter ZnT8 mediates granular sequestration of zinc ions. A genetic variant of human ZnT8 arising from a single nonsynonymous nucleotide change contributes to increased susceptibility to type-2 diabetes (T2D), but it remains unclear how the high risk variant (Arg-325), which is also a higher frequency (>50%) allele, is correlated with zinc transport activity. Here, we compared the activity of Arg-325 with that of a low risk ZnT8 variant (Trp-325). The Arg-325 variant was found to be more active than the Trp-325 form following induced expression in HEK293 cells. We further examined the functional consequences of changing lipid conditions to mimic the impact of lipid remodeling on ZnT8 activity during insulin granule biogenesis. Purified ZnT8 variants in proteoliposomes exhibited more than 4-fold functional tunability by the anionic phospholipids, lysophosphatidylcholine and cholesterol. Over a broad range of permissive lipid compositions, the Arg-325 variant consistently exhibited accelerated zinc transport kinetics versus the Trp-form. In agreement with the human genetic finding that rare loss-of-function mutations in ZnT8 are associated with reduced T2D risk, our results suggested that the common high risk Arg-325 variant is hyperactive, and thus may be targeted for inhibition to reduce T2D risk in the general populations.

Supporting NHS Cybersecurity During COVID-19 is Vital

2 April 2020

Joyce Hakmeh

Senior Research Fellow, International Security Programme; Co-Editor, Journal of Cyber Policy
The current crisis is an opportunity for the UK government to show agility in how it deals with cyber threats and how it cooperates with the private sector in creating cyber resilience.

2020-04-02-NHS-nurse-tech-cyber

The World Health Organization, US Department of Health and Human Services, and hospitals in Spain, France and the Czech Republic have all suffered cyberattacks during the ongoing COVID-19 crisis.

In the Czech Republic, a successful attack targeted a hospital with one of the country’s biggest COVID-19 testing laboratories, forcing its entire IT network to shut down, urgent surgical operations to be rescheduled, and patients to be moved to nearby hospitals. The attack also delayed dozens of COVID-19 test results and affected the hospital’s data transfer and storage, affecting the healthcare the hospital could provide.

In the UK, the National Health Service (NHS) is already in crisis mode, focused on providing beds and ventilators to respond to one of the largest peacetime threats ever faced. But supporting the health sector goes beyond increasing human resources and equipment capacity.

Health services ill-prepared

Cybersecurity support, both at organizational and individual level, is critical so health professionals can carry on saving lives, safely and securely. Yet this support is currently missing and the health services may be ill-prepared to deal with the aftermath of potential cyberattacks.

When the NHS was hit by the Wannacry ransomware attack in 2017 - one of the largest cyberattacks the UK has witnessed to date – it caused massive disruption, with at least 80 of the 236 trusts across England affected and thousands of appointments and operations cancelled. Fortunately, a ‘kill-switch’ activated by a cybersecurity researcher quickly brought it to a halt.

But the UK’s National Cyber Security Centre (NCSC), has been warning for some time against a cyber attack targeting national critical infrastructure sectors, including the health sector. A similar attack, known as category one (C1) attack, could cripple the UK with devastating consequences. It could happen and we should be prepared.

Although the NHS has taken measures since Wannacry to improve cybersecurity, its enormous IT networks, legacy equipment and the overlap between the operational and information technology (OT/IT) does mean mitigating current potential threats are beyond its ability.

And the threats have radically increased. More NHS staff with access to critical systems and patient health records are increasingly working remotely. The NHS has also extended its physical presence with new premises, such as the Nightingale hospital, potentially the largest temporary hospital in the world.

Radical change frequently means proper cybersecurity protocols are not put in place. Even existing cybersecurity processes had to be side-stepped because of the outbreak, such as the decision by NHS Digital to delay its annual cybersecurity audit until September. During this audit, health and care organizations submit data security and protection toolkits to regulators setting out their cybersecurity and cyber resilience levels.

The decision to delay was made to allow the NHS organizations to focus capacity on responding to COVID-19, but cybersecurity was highlighted as a high risk, and the importance of NHS and Social Care remaining resilient to cyberattacks was stressed.

The NHS is stretched to breaking point. Expecting it to be on top of its cybersecurity during these exceptionally challenging times is unrealistic, and could actually add to the existing risk.

Now is the time where new partnerships and support models should be emerging to support the NHS and help build its resilience. Now is the time where innovative public-private partnerships on cybersecurity should be formed.

Similar to the economic package from the UK chancellor and innovative thinking on ventilator production, the government should oversee a scheme calling on the large cybersecurity capacity within the private sector to step in and assist the NHS. This support can be delivered in many different ways, but it must be mobilized swiftly.

The NCSC for instance has led the formation of the Cyber Security Information Sharing Partnership (CiSP)— a joint industry and UK government initiative to exchange cyber threat information confidentially in real time with the aim of reducing the impact of cyberattacks on UK businesses.

CiSP comprises organizations vetted by NCSC which go through a membership process before being able to join. These members could conduct cybersecurity assessment and penetration testing for NHS organizations, retrospectively assisting in implementing key security controls which may have been overlooked.

They can also help by making sure NHS remote access systems are fully patched and advising on sensible security systems and approved solutions. They can identify critical OT and legacy systems and advise on their security.

The NCSC should continue working with the NHS to enhance provision of public comprehensive guidance on cyber defence and response to potential attack. This would show they are on top of the situation, projecting confidence and reassurance.

It is often said in every crisis lies an opportunity. This is an opportunity for the UK government to show agility in how it deals with cyber threats and how it cooperates with the private sector in creating cyber resilience.

It is an opportunity to lead a much-needed cultural change showing cybersecurity should never be an afterthought.

Can Protest Movements in the MENA Region Turn COVID-19 Into an Opportunity for Change?

29 April 2020

Dr Georges Fahmi

Associate Fellow, Middle East and North Africa Programme
The COVID-19 pandemic will not in itself result in political change in the MENA region, that depends on the ability of both governments and protest movements to capitalize on this moment. After all, crises do not change the world - people do.

2020-04-28-covid-19-protest-movement-mena.jpg

COVID-19 has offered regimes in the region the opportunity to end popular protest. The squares of Algiers, Baghdad, and Beirut – all packed with protesters over the past few months – are now empty due to the pandemic, and political gatherings have also been suspended. In Algeria, Iraq and Lebanon, COVID-19 has achieved what snipers, pro-regime propaganda, and even the economic crisis, could not.

Moreover, political regimes have taken advantage of the crisis to expand their control over the political sphere by arresting their opponents, such as in Algeria where the authorities have cracked down on a number of active voices of the Hirak movement. Similarly, in Lebanon, security forces have used the pandemic as an excuse to crush sit-ins held in Martyr’s Square in Beirut and Nour Square in Tripoli.

However, despite the challenges that the pandemic has brought, it also offers opportunities for protest movements in the region. While the crisis has put an end to popular mobilization in the streets, it has  created new forms of activism in the shape of solidarity initiatives to help those affected by its consequences.

In Iraq, for example, protest groups have directed their work towards awareness-raising and sharing essential food to help mitigate the problem of food shortages and rising prices across the country. In Algeria, Hirak activists have run online campaigns to raise awareness about the virus and have encouraged people to stay at home. Others have been cleaning and disinfecting public spaces. These initiatives increase the legitimacy of the protest movement, and if coupled with political messages, could offer these movements an important chance to expand their base of popular support.

Exposes economic vulnerability

Economic grievances, corruption and poor provision of public services have been among the main concerns of this recent wave of protests. This pandemic only further exposes the levels of economic vulnerability in the region. COVID-19 is laying bare the socio-economic inequalities in MENA countries; this is particularly evident in the numbers of people engaged in the informal economy with no access to social security, including health insurance and pensions.

Informal employment, approximately calculated by the share of the labour force not contributing to social security, is estimated to amount to 65.5% of total employment in Lebanon, 64.4% in Iraq, and 63.3% in Algeria. The crisis has underscored the vulnerability of this large percentage of the labour force who have been unable to afford the economic repercussions of following state orders to stay at home.

The situation has also called attention to the vital need for efficient public services and healthcare systems. According to the fifth wave of the Arab Barometer, 74.4% of people in Lebanon are dissatisfied with their country’s healthcare services, as are 67.8% of people in Algeria and 66.5% in Iraq.

Meanwhile, 66.2% of people in Lebanon believe it is necessary to pay a bribe in order to receive better healthcare, as do 56.2% of people in Iraq and 55.9% in Algeria. The COVID-19 crisis has highlighted the need for more government investment in public healthcare systems to render them more efficient and less corrupt, strengthening the protesters’ case for the need for radical socio-economic reforms.

On the geopolitical level, the crisis puts into question the stability-focused approach of Western powers towards the region. For years, Western powers have directed their aid towards security forces in the interests of combating terrorism but COVID-19 has proved itself to be a much more lethal challenge to both the region and the West.

Facing this new challenge requires international actors to reconsider their approach to include supporting health and education initiatives, as well as freedom of expression and transparency. As argued by Western policymakers themselves, it was China’s lack of transparency and slow response that enabled the proliferation of the virus, when it could have been contained in Wuhan back in December 2019.

This crisis therefore offers regional protest movements the opportunity to capitalize on this moment and push back against the policies of Western powers that have invested in regional stability only to the extent of combating Islamic jihad. 

But crises do not change the world, people do. The COVID-19 pandemic will not in itself result in political change in the MENA region. Rather, it brings opportunities and risks that, when exploited, will allow political actors to advance their own agendas. While the crisis has put an end to popular mobilization and allowed regimes to tighten their grip over the political sphere, behind these challenges lie real opportunities for protest movements.

The current situation represents a possibility for them to expand their popular base through solidarity initiatives and has exposed more widely the importance of addressing socio-economic inequalities. Finally, it offers the chance to challenge the stability-focused approach of Western powers towards the region which until now has predominantly focused on combating terrorism.

Proteomics of Campylobacter jejuni growth in deoxycholate reveals Cj0025c as a cystine transport protein required for wild-type human infection phenotypes [Research]

Campylobacter jejuni is a major cause of food-borne gastroenteritis. Proteomics by label-based two-dimensional liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) identified proteins associated with growth in 0.1% sodium deoxycholate (DOC, a component of gut bile salts), and system-wide validation was performed by data-independent acquisition (DIA-SWATH-MS). LC-MS/MS quantified 1326 proteins (~82% of the predicted C. jejuni proteome), of which 1104 were validated in additional biological replicates by DIA-SWATH-MS. DOC resulted in a profound proteome shift with 512 proteins showing significantly altered abundance. Induced proteins were associated with flagellar motility and antibiotic resistance; and these correlated with increased DOC motility and resistance to polymyxin B and ciprofloxacin. DOC also increased human Caco-2 cell adherence and invasion. Abundances of proteins involved in nutrient transport were altered by DOC and aligned with intracellular changes to their respective carbon sources. DOC increased intracellular levels of sulfur-containing amino acids (cysteine and methionine) and the dipeptide cystine (Cys-Cys), which also correlated with reduced resistance to oxidative stress. A DOC induced transport protein was Cj0025c, which has sequence similarity to bacterial Cys-Cys transporters. Deletion of cj0025c (cj0025c) resulted in proteome changes consistent with sulfur starvation, as well as attenuated invasion, reduced motility, atypical morphology, increased antimicrobial susceptibility and poor biofilm formation. Targeted metabolomics showed cj0025c was capable of utilizing known C. jejuni amino and organic acid substrates commensurate with wild-type. Medium Cys-Cys levels however, were maintained in cj0025c relative to wild-type. A toxic Cys-Cys mimic (selenocystine) inhibited wild-type growth, but not cj0025c. Provision of an alternate sulfur source (2 mM thiosulfate) restored cj0025c motility. Our data confirm that Cj0025c is a Cys-Cys transporter that we have named TcyP consistent with the nomenclature of homologous proteins in other species.

Rethinking youth bulge theory in policy and scholarship: incorporating critical gender analysis

7 May 2020 , Volume 96, Number 3

Lesley Pruitt

For decades ‘youth bulge’ theory has dominated understandings of youth in mainstream International Relations. Youth bulge theory has also become part of some public media analyses, mainstream political rhetoric, and even officially enshrined in the foreign policy of some states. Through the ‘youth bulge’ lens, youth—especially males—have been presented as current or future perpetrators of violence. However, this article argues that the youth bulge thesis postulated in mainstream IR is based on flawed theoretical assumptions. In particular, supporters of youth bulge theory fail to engage with existing research by feminist IR scholars and thus take on a biological essentialist approach. This has led to theoretical and practical misunderstandings of the roles youth play in relation to conflict, peace and security. These partial and biased understandings have also resulted in less effective policy-making. In critically reflecting on the ‘youth bulge’ thesis, this article argues that applying gender analysis is crucial to understanding the involvement of young people in general—and young men in particular—in conflict. Doing so will contribute to advancing more accurate analysis in scholarship and policy-making.

The widespread practice of illicit acquisition of a business or part of a business in the former Soviet states, known as ‘reiderstvo’ or asset-grabbing, is a major risk that disincentivises investment in the region.

It is distinct from the way corporate raiding occurs in the West and enabled by factors such as corruption and weak protection of property rights.

This roundtable will assess the practice of corporate raiding in Russia, Ukraine and Kazakhstan: its evolution over time, knock-on effects and potential solutions. The speakers will also address the implications for the UK legal system and possible policy responses.

In January 2019, the Ecumenical Patriarchate of Constantinople granted the Orthodox Church of Ukraine a self-governing status, ending its centuries-long subordination to the Moscow Patriarchate. The Russian Orthodox Church condemned this decision and severed its links with the Constantinople Patriarchate.

More than 500 parishes have left the Ukrainian Orthodox Church of the Moscow Patriarchate to join the newly independent Ukrainian Orthodox Church (UOC).

What challenges is the new church facing? Has its independence been recognized by other Orthodox churches? How is it affected by the schism between Constantinople and Moscow? What are UOC’s priorities in relations with the West and with the Orthodox world?

Serum amyloid A is not incorporated into HDL during HDL biogenesis [Research Articles]

Liver-derived serum amyloid A (SAA) is present in plasma where it is mainly associated with HDL and from which it is cleared more rapidly than are the other major HDL-associated apolipoproteins. Although evidence suggests that lipid-free and HDL-associated forms of SAA have different activities, the pathways by which SAA associates and disassociates with HDL are poorly understood. In this study, we investigated SAA lipidation by hepatocytes and how this lipidation relates to the formation of nascent HDL particles. We also examined hepatocyte-mediated clearance of lipid-free and HDL-associated SAA. We prepared hepatocytes from mice injected with lipopolysaccharide or an SAA-expressing adenoviral vector. Alternatively, we incubated primary hepatocytes from SAA-deficient mice with purified SAA. We analyzed conditioned media to determine the lipidation status of endogenously produced and exogenously added SAA. Examining the migration of lipidated species, we found that SAA is lipidated and forms nascent particles that are distinct from apoA-I-containing particles and that apoA-I lipidation is unaltered when SAA is overexpressed or added to the cells, indicating that SAA is not incorporated into apoA-I-containing HDL during HDL biogenesis. Like apoA-I formation, generation of SAA-containing particles was dependent on ABCA1, but not on scavenger receptor class B type I. Hepatocytes degraded significantly more SAA than apoA-I. Taken together, our results indicate that SAA’s lipidation and metabolism by the liver is independent of apoA-I and that SAA is not incorporated into HDL during HDL biogenesis.

Hexacosenoyl-CoA is the most abundant very long-chain acyl-CoA in ATP binding cassette transporter D1-deficient cells [Patient-Oriented and Epidemiological Research]

X-linked adrenoleukodystrophy (X-ALD) is an inherited disorder caused by deleterious mutations in the ABCD1 gene. The ABCD1 protein transports very long-chain FAs (VLCFAs) from the cytosol into the peroxisome where the VLCFAs are degraded through β-oxidation. ABCD1 dysfunction leads to VLCFA accumulation in individuals with X-ALD. FAs are activated by esterification to CoA before metabolic utilization. However, the intracellular pools and metabolic profiles of individual acyl-CoA esters have not been fully analyzed. In this study, we profiled the acyl-CoA species in fibroblasts from X-ALD patients and in ABCD1-deficient HeLa cells. We found that hexacosenoyl (26:1)-CoA, but not hexacosanoyl (26:0)-CoA, was the most abundantly concentrated among the VLCFA-CoA species in these cells. We also show that 26:1-CoA is mainly synthesized from oleoyl-CoA, and the metabolic turnover rate of 26:1-CoA was almost identical to that of oleoyl-CoA in both WT and ABCD1-deficient HeLa cells. The findings of our study provide precise quantitative and metabolic information of each acyl-CoA species in living cells. Our results suggest that VLCFA is endogenously synthesized as VLCFA-CoA through a FA elongation pathway and is then efficiently converted to other metabolites, such as phospholipids, in the absence of ABCD1.

SSO and other putative inhibitors of FA transport across membranes by CD36 disrupt intracellular metabolism, but do not affect FA translocation [Research Articles]

Membrane-bound proteins have been proposed to mediate the transport of long-chain FA (LCFA) transport through the plasma membrane (PM). These proposals are based largely on reports that PM transport of LCFAs can be blocked by a number of enzymes and purported inhibitors of LCFA transport. Here, using the ratiometric pH indicator (2',7'-bis-(2-carboxyethyl)-5-(and-6-)-carboxyfluorescein and acrylodated intestinal FA-binding protein-based dual fluorescence assays, we investigated the effects of nine inhibitors of the putative FA transporter protein CD36 on the binding and transmembrane movement of LCFAs. We particularly focused on sulfosuccinimidyl oleate (SSO), reported to be a competitive inhibitor of CD36-mediated LCFA transport. Using these assays in adipocytes and inhibitor-treated protein-free lipid vesicles, we demonstrate that rapid LCFA transport across model and biological membranes remains unchanged in the presence of these purported inhibitors. We have previously shown in live cells that CD36 does not accelerate the transport of unesterified LCFAs across the PM. Our present experiments indicated disruption of LCFA metabolism inside the cell within minutes upon treatment with many of the "inhibitors" previously assumed to inhibit LCFA transport across the PM. Furthermore, using confocal microscopy and a specific anti-SSO antibody, we found that numerous intracellular and PM-bound proteins are SSO-modified in addition to CD36. Our results support the hypothesis that LCFAs diffuse rapidly across biological membranes and do not require an active protein transporter for their transmembrane movement.

Substrate recognition and ATPase activity of the E. coli cysteine/cystine ABC transporter YecSC-FliY [Microbiology]

Sulfur is essential for biological processes such as amino acid biogenesis, iron–sulfur cluster formation, and redox homeostasis. To acquire sulfur-containing compounds from the environment, bacteria have evolved high-affinity uptake systems, predominant among which is the ABC transporter family. Theses membrane-embedded enzymes use the energy of ATP hydrolysis for transmembrane transport of a wide range of biomolecules against concentration gradients. Three distinct bacterial ABC import systems of sulfur-containing compounds have been identified, but the molecular details of their transport mechanism remain poorly characterized. Here we provide results from a biochemical analysis of the purified Escherichia coli YecSC-FliY cysteine/cystine import system. We found that the substrate-binding protein FliY binds l-cystine, l-cysteine, and d-cysteine with micromolar affinities. However, binding of the l- and d-enantiomers induced different conformational changes of FliY, where the l- enantiomer–substrate-binding protein complex interacted more efficiently with the YecSC transporter. YecSC had low basal ATPase activity that was moderately stimulated by apo FliY, more strongly by d-cysteine–bound FliY, and maximally by l-cysteine– or l-cystine–bound FliY. However, at high FliY concentrations, YecSC reached maximal ATPase rates independent of the presence or nature of the substrate. These results suggest that FliY exists in a conformational equilibrium between an open, unliganded form that does not bind to the YecSC transporter and closed, unliganded and closed, liganded forms that bind this transporter with variable affinities but equally stimulate its ATPase activity. These findings differ from previous observations for similar ABC transporters, highlighting the extent of mechanistic diversity in this large protein family.

Detailed analyses of the crucial functions of Zn transporter proteins in alkaline phosphatase activation [Enzymology]

Numerous zinc ectoenzymes are metalated by zinc and activated in the compartments of the early secretory pathway before reaching their destination. Zn transporter (ZNT) proteins located in these compartments are essential for ectoenzyme activation. We have previously reported that ZNT proteins, specifically ZNT5–ZNT6 heterodimers and ZNT7 homodimers, play critical roles in the activation of zinc ectoenzymes, such as alkaline phosphatases (ALPs), by mobilizing cytosolic zinc into these compartments. However, this process remains incompletely understood. Here, using genetically-engineered chicken DT40 cells, we first determined that Zrt/Irt-like protein (ZIP) transporters that are localized to the compartments of the early secretory pathway play only a minor role in the ALP activation process. These transporters included ZIP7, ZIP9, and ZIP13, performing pivotal functions in maintaining cellular homeostasis by effluxing zinc out of the compartments. Next, using purified ALP proteins, we showed that zinc metalation on ALP produced in DT40 cells lacking ZNT5–ZNT6 heterodimers and ZNT7 homodimers is impaired. Finally, by genetically disrupting both ZNT5 and ZNT7 in human HAP1 cells, we directly demonstrated that the tissue-nonspecific ALP-activating functions of both ZNT complexes are conserved in human cells. Furthermore, using mutant HAP1 cells, we uncovered a previously-unrecognized and unique spatial regulation of ZNT5–ZNT6 heterodimer formation, wherein ZNT5 recruits ZNT6 to the Golgi apparatus to form the heterodimeric complex. These findings fill in major gaps in our understanding of the molecular mechanisms underlying zinc ectoenzyme activation in the compartments of the early secretory pathway.

MtrP, a putative methyltransferase in Corynebacteria, is required for optimal membrane transport of trehalose mycolates [Lipids]

Pathogenic bacteria of the genera Mycobacterium and Corynebacterium cause severe human diseases such as tuberculosis (Mycobacterium tuberculosis) and diphtheria (Corynebacterium diphtheriae). The cells of these species are surrounded by protective cell walls rich in long-chain mycolic acids. These fatty acids are conjugated to the disaccharide trehalose on the cytoplasmic side of the bacterial cell membrane. They are then transported across the membrane to the periplasm where they act as donors for other reactions. We have previously shown that transient acetylation of the glycolipid trehalose monohydroxycorynomycolate (hTMCM) enables its efficient transport to the periplasm in Corynebacterium glutamicum and that acetylation is mediated by the membrane protein TmaT. Here, we show that a putative methyltransferase, encoded at the same genetic locus as TmaT, is also required for optimal hTMCM transport. Deletion of the C. glutamicum gene NCgl2764 (Rv0224c in M. tuberculosis) abolished acetyltrehalose monocorynomycolate (AcTMCM) synthesis, leading to accumulation of hTMCM in the inner membrane and delaying its conversion to trehalose dihydroxycorynomycolate (h2TDCM). Complementation with NCgl2764 normalized turnover of hTMCM to h2TDCM. In contrast, complementation with NCgl2764 derivatives mutated at residues essential for methyltransferase activity failed to rectify the defect, suggesting that NCgl2764/Rv0224c encodes a methyltransferase, designated here as MtrP. Comprehensive analyses of the individual mtrP and tmaT mutants and of a double mutant revealed strikingly similar changes across several lipid classes compared with WT bacteria. These findings indicate that both MtrP and TmaT have nonredundant roles in regulating AcTMCM synthesis, revealing additional complexity in the regulation of trehalose mycolate transport in the Corynebacterineae.

Maternal Obesity and Western-Style Diet Impair Fetal and Juvenile Offspring Skeletal Muscle Insulin-Stimulated Glucose Transport in Nonhuman Primates

Infants born to mothers with obesity have a greater risk for childhood obesity and metabolic diseases; however, the underlying biological mechanisms remain poorly understood. We used a Japanese macaque model to investigate whether maternal obesity combined with a western-style diet (WSD) impairs offspring muscle insulin action. Adult females were fed a control or WSD prior to and during pregnancy through lactation, and offspring subsequently weaned to a control or WSD. Muscle glucose uptake and signaling were measured ex vivo in fetal (n=5-8/group) and juvenile offspring (n=8/group). In vivo signaling was evaluated after an insulin bolus just prior to weaning (n=4-5/group). Maternal WSD reduced insulin-stimulated glucose uptake and impaired insulin signaling at the level of Akt phosphorylation in fetal muscle. In juvenile offspring, insulin-stimulated glucose uptake was similarly reduced by both maternal and post-weaning WSD and corresponded to modest reductions in insulin-stimulated Akt phosphorylation relative to controls. We conclude that maternal WSD leads to a persistent decrease in offspring muscle insulin-stimulated glucose uptake even in the absence of increased offspring adiposity or markers of systemic insulin resistance. Switching offspring to a healthy diet did not reverse the effects of maternal WSD on muscle insulin action suggesting earlier interventions may be warranted.

Inhibition of glycosphingolipid biosynthesis reverts multidrug resistance by differentially modulating ABC transporters in chronic myeloid leukemias [Cell Biology]

Multidrug resistance (MDR) in cancer arises from cross-resistance to structurally- and functionally-divergent chemotherapeutic drugs. In particular, MDR is characterized by increased expression and activity of ATP-binding cassette (ABC) superfamily transporters. Sphingolipids are substrates of ABC proteins in cell signaling, membrane biosynthesis, and inflammation, for example, and their products can favor cancer progression. Glucosylceramide (GlcCer) is a ubiquitous glycosphingolipid (GSL) generated by glucosylceramide synthase, a key regulatory enzyme encoded by the UDP-glucose ceramide glucosyltransferase (UGCG) gene. Stressed cells increase de novo biosynthesis of ceramides, which return to sub-toxic levels after UGCG mediates incorporation into GlcCer. Given that cancer cells seem to mobilize UGCG and have increased GSL content for ceramide clearance, which ultimately contributes to chemotherapy failure, here we investigated how inhibition of GSL biosynthesis affects the MDR phenotype of chronic myeloid leukemias. We found that MDR is associated with higher UGCG expression and with a complex GSL profile. UGCG inhibition with the ceramide analog d-threo-1-(3,4,-ethylenedioxy)phenyl-2-palmitoylamino-3-pyrrolidino-1-propanol (EtDO-P4) greatly reduced GSL and monosialotetrahexosylganglioside levels, and co-treatment with standard chemotherapeutics sensitized cells to mitochondrial membrane potential loss and apoptosis. ABC subfamily B member 1 (ABCB1) expression was reduced, and ABCC-mediated efflux activity was modulated by competition with nonglycosylated ceramides. Consistently, inhibition of ABCC-mediated transport reduced the efflux of exogenous C6-ceramide. Overall, UGCG inhibition impaired the malignant glycophenotype of MDR leukemias, which typically overcomes drug resistance through distinct mechanisms. This work sheds light on the involvement of GSL in chemotherapy failure, and its findings suggest that targeted GSL modulation could help manage MDR leukemias.

POSTPONED: Supporting Civic Space: The Role and Impact of the Private Sector

Invitation Only Research Event

16 March 2020 - 11:00am to 5:00pm

Chatham House | 10 St James's Square | London | SW1Y 4LE

A healthy civic space is vital for an enabling business environment. In recognition of this, a growing number of private sector actors are challenging, publicly or otherwise, the deteriorating environment for civic freedoms.

However, this corporate activism is often limited and largely ad hoc. It remains confined to a small cluster of multinationals leaving potential routes for effective coordination and collaboration with other actors underexplored.

This roundtable will bring together a diverse and international group of business actors, civil society actors and foreign policy experts to exchange perspectives and experiences on how the private sector can be involved in issues around civic space. The meeting will provide an opportunity to explore the drivers of – and barriers to – corporate activism, develop a better understanding of existing initiatives, identify good practice and discuss practical strategies for the business community.

This meeting will be the first of a series of roundtables at Chatham House in support of initiatives to build broad alliances for the protection of civic space. 

Attendance at this event is by invitation only. 

PLEASE NOTE THIS EVENT IS POSTPONED UNTIL FURTHER NOTICE.

Exploring the Obstacles and Opportunities for Expanded UK-Latin American Trade and Investment

Invitation Only Research Event

14 January 2020 - 8:30am to 11:00am

Chatham House | 10 St James's Square | London | SW1Y 4LE

Trade and investment between the UK and Latin America is woefully underdeveloped. Latin America’s agricultural powerhouses Brazil and Argentina only accounted for a total of 1.6% of the UK’s agricultural market across eight sectors in 2018, all of those areas in which Argentina and Brazil have substantial comparative advantages. 

Conversely, UK exports to the large Latin American economies remain far below their potential.  To cite a few examples, in 2018 in the electrical equipment sector, the UK only exported $95.7 million of those products to Brazil, making the ninth largest economy in the world only the 42nd export market for those goods from the UK; Mexico only imported $91.4 million of UK-made electrical goods, placing it directly behind Brazil as UK’s market for those goods.

As we look to the future, any improvement to the relationship will depend on two factors: 1) how the UK leaves the EU and 2) whether Latin American agricultural producers can improve their environmental practices and can meet the production standards established by the EU and likely maintained by a potential post-Brexit Britain.

In the first meeting of the working group,  Chatham House convened a range of policymakers, practitioners and academics to explore this topic in depth, identify the key issues driving this trend, and begin to consider how improvements might best be made. Subsequent meetings will focus on specific sectors in commerce and investment.

We would like to thank BTG Pactual, Cairn Energy plc, Diageo, Equinor, Fresnillo Management Services, HSBC Holdings plc and Wintershall Dea for their generous support of the Latin America Initiative.

The widespread practice of illicit acquisition of a business or part of a business in the former Soviet states, known as ‘reiderstvo’ or asset-grabbing, is a major risk that disincentivises investment in the region.

It is distinct from the way corporate raiding occurs in the West and enabled by factors such as corruption and weak protection of property rights.

This roundtable will assess the practice of corporate raiding in Russia, Ukraine and Kazakhstan: its evolution over time, knock-on effects and potential solutions. The speakers will also address the implications for the UK legal system and possible policy responses.

Archbishop Yevstraty (Zoria) of Chernihiv, Deputy Head of Department for External Church Relations, Ukrainian Orthodox Church (Orthodox Church of Ukraine)

In January 2019, the Ecumenical Patriarchate of Constantinople granted the Orthodox Church of Ukraine a self-governing status, ending its centuries-long subordination to the Moscow Patriarchate. The Russian Orthodox Church condemned this decision and severed its links with the Constantinople Patriarchate.

More than 500 parishes have left the Ukrainian Orthodox Church of the Moscow Patriarchate to join the newly independent Ukrainian Orthodox Church (UOC).

What challenges is the new church facing? Has its independence been recognized by other Orthodox churches? How is it affected by the schism between Constantinople and Moscow? What are UOC’s priorities in relations with the West and with the Orthodox world?
