Biochemical and structural insights into how amino acids regulate pyruvate kinase muscle isoform 2 [Enzymology]

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.

COVID-19 is a sharp reminder of why trade policy matters. As the UK works to forge new trade deals, it must align its trade policy agenda with its climate ambition.

COVID-19 is a sharp reminder of why trade and climate policy matters. How can governments maintain access to critical goods and services, and ensure global supply chains function in times of crisis?

The timing of many trade negotiations is now increasingly uncertain, as are the UK’s plans to host COP26 in November. Policy work continues, however, and the EU has released its draft negotiating text for the new UK-EU trade deal, which includes a sub-chapter specifically devoted to climate. 

This is a timely reminder both of the pressing need for the UK to integrate its trade and climate policymaking and to use the current crisis-induced breathing space in international negotiations - however limited - to catch up on both strategy and priorities on this critical policy intersection.

The UK government has moved fast to reset its external trade relations post-Brexit. In the past month it formally launched bilateral negotiations with the EU and took up a seat at the World Trade Organization (WTO) as an independent member. Until the COVID-19 crisis hit, negotiations were also poised to start with the US.

The UK is also in the climate spotlight as host of COP26, the most important international climate negotiation since Paris in 2015, which presents a vital opportunity for the government to show leadership by aligning its trade agenda with its climate and sustainability commitments in bold new ways.

Not just an empty aspiration

This would send a signal that ‘Global Britain’ is not just an empty aspiration, but a concrete commitment to lead.

Not only is concerted action on the climate crisis a central priority for UK citizens, a growing and increasingly vocal group of UK businesses committed to decarbonization are calling on the government to secure a more transparent and predictable international market place that supports climate action by business.

With COP26, the UK has a unique responsibility to push governments to ratchet up ambition in the national contributions to climate action – and to promote coherence between climate ambition and wider economic policymaking, including on trade. If Britain really wants to lead, here are some concrete actions it should take.

At the national level, the UK can pioneer new ways to put environmental sustainability – and climate action in particular - at the heart of its trade agenda. Achieving the government’s ambitious Clean Growth Strategy - which seeks to make the UK the global leader in a range of industries including electric cars and offshore wind – should be a central objective of UK trade policy.

The UK should re-orient trade policy frameworks to incentivize the shift toward a more circular and net zero global economy. And all elements of UK trade policy could be assessed against environmental objectives - for example, their contribution to phasing out fossil fuels, helping to reverse overexploitation of natural resources, and support for sustainable agriculture and biodiversity.

In its bilateral and regional trade negotiations, the UK can and should advance its environment, climate and trade goals in tandem, and implementation of the Paris Agreement must be a core objective of the UK trade strategy.

A core issue for the UK is how to ensure that efforts to decarbonise the economy are not undercut by imports from high-carbon producers. Here, a ‘border carbon adjustment (BCA)’ - effectively a tax on the climate pollution of imports - would support UK climate goals. The EU draft negotiating text released yesterday put the issue of BCAs front and centre, making crystal clear that the intersection of climate, environment and trade policy goals will be a central issue for UK-EU trade negotiations.

Even with the United States, a trade deal can and should still be seized as a way to incentivize the shift toward a net zero and more circular economy. At the multilateral level, as a new independent WTO member, the UK has an opportunity to help build a forward-looking climate and trade agenda.

The UK could help foster dialogue, research and action on a cluster of ‘climate and trade’ issues that warrant more focused attention at the WTO. These include the design of carbon pricing policies at the border that are transparent, fair and support a just transition; proposals for a climate waiver for WTO rules; and identification of ways multilateral trade cooperation could promote a zero carbon and more circular global economy.  

To help nudge multilateral discussion along, the UK could also ask to join a critical ‘path finder’ effort by six governments, led by New Zealand, to pursue an agreement on climate change, trade and sustainability (ACCTS). This group aims to find ways forward on three central trade and climate issues: removing fossil fuel subsidies, climate-related labelling, and promoting trade in climate-friendly goods and services.

At present, the complex challenges at the intersection of climate, trade and development policy are too often used to defer or side-step issues deemed ‘too hard’ or ‘too sensitive’ to tackle. The UK could help here by working to ensure multilateral climate and trade initiatives share adjustment burdens, recognise the historical responsibility of developed countries, and do not unfairly disadvantage developing countries - especially the least developed.

Many developing countries are keen to promote climate-friendly exports as part of wider export diversification strategies  and want to reap greater returns from greener global value chains. Further, small island states and least-developed countries – many of which are Commonwealth members – that are especially vulnerable to the impacts of climate change and natural disasters, need support to adapt in the face of trade shocks and to build climate-resilient, trade-related infrastructure and export sectors.

As an immediate next step, the UK should actively support the growing number of WTO members in favour of a WTO Ministerial Statement on environmental sustainability and trade. It should work with its key trading partners in the Commonwealth and beyond to ensure the agenda is inclusive, supports achievement of the UN Sustainable Development Goals (SDGs) and helps developing countries benefit from a more environmentally sustainable global economy.

As the UK prepares to host COP26, negotiates deals with the EU and US, and prepares for its first WTO Ministerial meeting as an independent member, it must show it can lead the way nationally, bilaterally, and multilaterally. And to ensure the government acts, greater engagement from the UK’s business, civil society and research sectors is critical – we need all hands on deck to forge and promote concrete proposals for aligning UK trade policy with the climate ambition our world needs.

Asian States Must Rethink Their Approach to Digital Governance

17 January 2020

Vasuki Shastry

Associate Fellow, Asia-Pacific Programme
Too many governments in the region are focusing on control and surveillance instead of citizens’ rights.

2020-01-17-KashInt.jpg

Asia’s political class learnt many lessons on digital governance in 2019, not all of them positive.

The prolonged protests in Hong Kong and India, led by disaffected young citizenry and enabled by social media tools, powerfully demonstrated how things could spiral out of control when the virtual and the real streets come together.

Not surprisingly, governments across the region are taking a step back. Instead of placing the citizen at the heart of digital public policy – with privacy, trust, security and inclusion as drivers of digital governance – Asian governments are focusing instead on surveillance and command and control, which contradicts the spirit of a decentralized Internet and undermines citizen’s rights.

Asia’s digital governance is fragmenting from the global norm and morphing into two platforms with remarkably similar characteristics.

One is a China-driven model aptly called the Great Firewall where surveillance of citizens is an explicit objective and any external material deemed to be subversive is kept out. A complementary model has also emerged more recently, which can best be described as China-light, which seeks to emulate the control aspects of the Great Firewall.

There are of course overlaps between emulators of the China model (this list includes Vietnam, Myanmar, Cambodia and Laos) and those pursuing China-light (Singapore, India, Indonesia, Bangladesh, Sri Lanka, the Philippines, Thailand and Malaysia). A common thread running through these two approaches, which differ only in intensity and scope, is the belief that the state is best positioned to police social media and protect the rights of citizens.

This was not how it was supposed to be. A decade ago, Asian political leaders spoke about the virtues of an open internet. Such talk has faded, and a narrowing of Asia’s digital space is taking place against a backdrop of an intensifying trade war between America and China, where regional supply chains run the risk of a decoupling into distinct Sino and American spheres, upending Asia’s durable economic model of the past few decades.

Digital fragmentation in the world’s fastest growing region, with five G20 members, will complicate efforts to build global governance and standards.

Asia’s digital landscape

Asian governments, including democratic ones, have developed an unhealthy obsession with what their citizens are up to on a daily basis. Their solution is round-the-clock monitoring in cities and towns, powered by new surveillance technologies.

Name tagging and facial recognition to track movement of citizens has become pervasive across the region, with China emerging as the preferred source of technology, knowledge, and techniques. While India’s Supreme Court has ruled that privacy is a fundamental right, translating this into concrete citizen’s protections will be difficult with the Modi government eager to emulate China’s approach.

Asian governments are also following China in requiring that their citizen’s data be housed within national borders and are rebelling against the established practice of data offshoring.

In the post-Snowden era and amidst increasing cyber risks, there are rational national security reasons for why governments may want to ring-fence customer data within national boundaries. However, Asian governments are paying little or no attention to how companies are using customer data within national boundaries, with widespread abuses going unchecked.

Global standards are still evolving and there is a strong case here for a uniform regional approach, perhaps via ASEAN or APEC, on standards governing customer privacy, payments, data collection and handling. Big tech companies and platforms operate across much of Asia and a regional approach will curb their current instinct of conducting regulatory arbitrage.

There is a genuine problem in Asia, as elsewhere in the world, with the proliferation of fake news and extremism. But instead of addressing the source of this problem, governments are clamping down by generously expanding the definition of fake news (Singapore) or by shutting down the internet altogether (India, Sri Lanka, and China being serial offenders).

As disseminators of news of all stripes, including the fake variant, the big tech firms have a primary responsibility in policing their platforms. However, the regulatory capacity of many Asian governments to monitor this is weak and in crisis situations, governments prefer to shut the pipes altogether.

Digitalization of course is not all about surveillance and holds the promise of driving inclusion. There is considerable hype within Asia on the promise of fintech as an enabler of this inclusion.

Hong Kong and Singapore are licensing new digital banks, India’s UPI (unified payments interface) is reducing friction in domestic payments and China’s BAT companies (Baidu, Alibaba, Tencent) are disrupting traditional commerce and payments, and seeking to expand in the region.

However, there is an elite focus in many of these initiatives, with the target market being the region’s rising middle class rather than those at the bottom of the income ladder. Making fintech work for all will require micro-initiatives with the support of NGOs, local governments and small enterprises, with the objective of digitalizing microfinance.

Here developing Asia will again benefit from learning from each other and in building regional approaches. India’s Aadhar for example, with appropriate security safeguards, is a model for Asia in terms of building digital identity.

Given differing regional and national objectives, it is difficult to imagine a global accord for digital governance any time soon. However, by signing on to the Regional Comprehensive Economic Partnership (RCEP) and the Comprehensive and Progressive Agreement for Transpacific Partnership (CPTPP, the successor to the TPP), Asia has consistently demonstrated its leadership in trade and regional governance.

This is why the region needs to come together to ensure that the promise and potential of digitalization flows evenly and equitably to the region, with the region’s 3.8 billion citizens at the heart, rather than at the margins of sensible public policy.

Putting Music on the Map

Mathematics and music have long been closely associated. Now a recent mathematical breakthrough uses topology (a generalization of geometry) to represent musical chords as points in a space called an orbifold, which twists and folds back on itself much like a Mobius strip does. This representation makes sense musically in that sounds that are far apart in one sense yet similar in another, such as two notes that are an octave apart, are identified in the space.This latest insight provides a way to analyze any type of music. In the case of Western music, pleasing chords lie near the center of the orbifolds and pleasing melodies are paths that link nearby chords. Yet despite the new connection between music and coordinate geometry, music is still more than a connect-the-dots exercise, just as mathematics is more than addition and multiplication.

Nuclear Tensions Must Not Be Sidelined During Coronavirus

1 May 2020

Ana Alecsandru

Research Assistant, International Security Programme
Although the pandemic means the Nuclear Non-Proliferation Treaty (NPT) Review Conference (RevCon) is postponed, the delay could be an opportunity to better the health of the NPT regime.

Despite face-to-face diplomatic meetings being increasingly rare during the current disruption, COVID-19 will ultimately force a redefinition of national security and defence spending priorities, and this could provide the possibility of an improved political climate at RevCon when it happens in 2021.

With US presidential elections due in November and a gradual engagement growing between the EU and Iran, there could be a new context for more cooperation between states by 2021. Two key areas of focus over the coming months will be the arms control talks between the United States and Russia, and Iran’s compliance with the 2015 Joint Comprehensive Plan of Action (JCPOA), also known as the Iran Nuclear Deal.

It is too early to discern the medium- and longer-term consequences of COVID-19 for defence ministries, but a greater focus on societal resilience and reinvigorating economic productivity will likely undercut the rationale for expensive nuclear modernization.

Therefore, extending the current New START (Strategic Arms Reduction Treaty) would be the best, most practical option to give both Russia and the United States time to explore more ambitious multilateral arms control measures, while allowing their current focus to remain on the pandemic and economic relief.

Continuing distrust

But with the current treaty — which limits nuclear warheads, missiles, bombers, and launchers — due to expire in February 2021, the continuing distrust between the United States and Russia makes this extension hard to achieve, and a follow-on treaty even less likely.

Prospects for future bilateral negotiations are hindered by President Donald Trump’s vision for a trilateral arms control initiative involving both China and Russia. But China opposes this on the grounds that its nuclear arsenal is far smaller than that of the two others.

While there appears to be agreement that the nuclear arsenals of China, France, and the UK (the NPT nuclear-weapons states) and those of the states outside the treaty (India, Pakistan, North Korea, and Israel) will all have to be taken into account going forward, a practical mechanism for doing so proves elusive.

If Joe Biden wins the US presidency he seems likely to pursue an extension of the New START treaty and could also prevent a withdrawal from the Open Skies treaty, the latest arms control agreement targeted by the Trump administration.

Under a Biden administration, the United States would also probably re-join the JCPOA, provided Tehran returned to strict compliance with the deal. Biden could even use the team that negotiated the Iran deal to advance the goal of denuclearization of the Korean peninsula.

For an NPT regime already confronted by a series of longstanding divergences, it is essential that Iran remains a signatory especially as tensions between Iran and the United States have escalated recently — due to the Qassim Suleimani assassination and the recent claim by Iran’s Revolutionary Guard Corps to have successfully placed the country’s first military satellite into orbit.

This announcement raised red flags among experts about whether Iran is developing intercontinental ballistic missiles due to the dual-use nature of space technology. The satellite launch — deeply troubling for Iran’s neighbours and the EU countries — may strengthen the US argument that it is a cover for the development of ballistic missiles capable of delivering nuclear weapons.

However, as with many other countries, Iran is struggling with a severe coronavirus crisis and will be pouring its scientific expertise and funds into that rather than other efforts — including the nuclear programme.

Those European countries supporting the trading mechanism INSTEX (Instrument in Support of Trade Exchanges) for sending humanitarian goods into Iran could use this crisis to encourage Iran to remain in compliance with the JCPOA and its NPT obligations.

France, Germany and the UK (the E3) have already successfully concluded the first transaction, which was to facilitate the export of medical goods from Europe to Iran. But the recent Iranian escalatory steps will most certainly place a strain on the preservation of this arrangement.

COVID-19 might have delayed Iran’s next breach of the 2015 nuclear agreement but Tehran will inevitably seek to strengthen its hand before any potential negotiations with the United States after the presidential elections.

As frosty US-Iranian relations — exacerbated by the coronavirus pandemic — prevent diplomatic negotiations, this constructive engagement between the E3 and Iran might prove instrumental in reviving the JCPOA and ensuring Iran stays committed to both nuclear non-proliferation and disarmament.

While countries focus their efforts on tackling the coronavirus pandemic, it is understandable resources may be limited for other global challenges, such as the increasing risk of nuclear weapons use across several regions.

But the potential ramifications of the COVID-19 crisis for the NPT regime are profound. Ongoing tensions between the nuclear-armed states must not be ignored while the world’s focus is elsewhere, and the nuclear community should continue to work together to progress nuclear non-proliferation and disarmament, building bridges of cooperation and trust that can long outlast the pandemic.

COVID-19 is a sharp reminder of why trade policy matters. As the UK works to forge new trade deals, it must align its trade policy agenda with its climate ambition.

COVID-19 is a sharp reminder of why trade and climate policy matters. How can governments maintain access to critical goods and services, and ensure global supply chains function in times of crisis?

The timing of many trade negotiations is now increasingly uncertain, as are the UK’s plans to host COP26 in November. Policy work continues, however, and the EU has released its draft negotiating text for the new UK-EU trade deal, which includes a sub-chapter specifically devoted to climate. 

This is a timely reminder both of the pressing need for the UK to integrate its trade and climate policymaking and to use the current crisis-induced breathing space in international negotiations - however limited - to catch up on both strategy and priorities on this critical policy intersection.

The UK government has moved fast to reset its external trade relations post-Brexit. In the past month it formally launched bilateral negotiations with the EU and took up a seat at the World Trade Organization (WTO) as an independent member. Until the COVID-19 crisis hit, negotiations were also poised to start with the US.

The UK is also in the climate spotlight as host of COP26, the most important international climate negotiation since Paris in 2015, which presents a vital opportunity for the government to show leadership by aligning its trade agenda with its climate and sustainability commitments in bold new ways.

Not just an empty aspiration

This would send a signal that ‘Global Britain’ is not just an empty aspiration, but a concrete commitment to lead.

Not only is concerted action on the climate crisis a central priority for UK citizens, a growing and increasingly vocal group of UK businesses committed to decarbonization are calling on the government to secure a more transparent and predictable international market place that supports climate action by business.

With COP26, the UK has a unique responsibility to push governments to ratchet up ambition in the national contributions to climate action – and to promote coherence between climate ambition and wider economic policymaking, including on trade. If Britain really wants to lead, here are some concrete actions it should take.

At the national level, the UK can pioneer new ways to put environmental sustainability – and climate action in particular - at the heart of its trade agenda. Achieving the government’s ambitious Clean Growth Strategy - which seeks to make the UK the global leader in a range of industries including electric cars and offshore wind – should be a central objective of UK trade policy.

The UK should re-orient trade policy frameworks to incentivize the shift toward a more circular and net zero global economy. And all elements of UK trade policy could be assessed against environmental objectives - for example, their contribution to phasing out fossil fuels, helping to reverse overexploitation of natural resources, and support for sustainable agriculture and biodiversity.

In its bilateral and regional trade negotiations, the UK can and should advance its environment, climate and trade goals in tandem, and implementation of the Paris Agreement must be a core objective of the UK trade strategy.

A core issue for the UK is how to ensure that efforts to decarbonise the economy are not undercut by imports from high-carbon producers. Here, a ‘border carbon adjustment (BCA)’ - effectively a tax on the climate pollution of imports - would support UK climate goals. The EU draft negotiating text released yesterday put the issue of BCAs front and centre, making crystal clear that the intersection of climate, environment and trade policy goals will be a central issue for UK-EU trade negotiations.

Even with the United States, a trade deal can and should still be seized as a way to incentivize the shift toward a net zero and more circular economy. At the multilateral level, as a new independent WTO member, the UK has an opportunity to help build a forward-looking climate and trade agenda.

The UK could help foster dialogue, research and action on a cluster of ‘climate and trade’ issues that warrant more focused attention at the WTO. These include the design of carbon pricing policies at the border that are transparent, fair and support a just transition; proposals for a climate waiver for WTO rules; and identification of ways multilateral trade cooperation could promote a zero carbon and more circular global economy.  

To help nudge multilateral discussion along, the UK could also ask to join a critical ‘path finder’ effort by six governments, led by New Zealand, to pursue an agreement on climate change, trade and sustainability (ACCTS). This group aims to find ways forward on three central trade and climate issues: removing fossil fuel subsidies, climate-related labelling, and promoting trade in climate-friendly goods and services.

At present, the complex challenges at the intersection of climate, trade and development policy are too often used to defer or side-step issues deemed ‘too hard’ or ‘too sensitive’ to tackle. The UK could help here by working to ensure multilateral climate and trade initiatives share adjustment burdens, recognise the historical responsibility of developed countries, and do not unfairly disadvantage developing countries - especially the least developed.

Many developing countries are keen to promote climate-friendly exports as part of wider export diversification strategies  and want to reap greater returns from greener global value chains. Further, small island states and least-developed countries – many of which are Commonwealth members – that are especially vulnerable to the impacts of climate change and natural disasters, need support to adapt in the face of trade shocks and to build climate-resilient, trade-related infrastructure and export sectors.

As an immediate next step, the UK should actively support the growing number of WTO members in favour of a WTO Ministerial Statement on environmental sustainability and trade. It should work with its key trading partners in the Commonwealth and beyond to ensure the agenda is inclusive, supports achievement of the UN Sustainable Development Goals (SDGs) and helps developing countries benefit from a more environmentally sustainable global economy.

As the UK prepares to host COP26, negotiates deals with the EU and US, and prepares for its first WTO Ministerial meeting as an independent member, it must show it can lead the way nationally, bilaterally, and multilaterally. And to ensure the government acts, greater engagement from the UK’s business, civil society and research sectors is critical – we need all hands on deck to forge and promote concrete proposals for aligning UK trade policy with the climate ambition our world needs.

Nuclear Tensions Must Not Be Sidelined During Coronavirus

1 May 2020

Research Assistant, International Security Programme
Although the pandemic means the Nuclear Non-Proliferation Treaty (NPT) Review Conference (RevCon) is postponed, the delay could be an opportunity to better the health of the NPT regime.

Despite face-to-face diplomatic meetings being increasingly rare during the current disruption, COVID-19 will ultimately force a redefinition of national security and defence spending priorities, and this could provide the possibility of an improved political climate at RevCon when it happens in 2021.

With US presidential elections due in November and a gradual engagement growing between the EU and Iran, there could be a new context for more cooperation between states by 2021. Two key areas of focus over the coming months will be the arms control talks between the United States and Russia, and Iran’s compliance with the 2015 Joint Comprehensive Plan of Action (JCPOA), also known as the Iran Nuclear Deal.

It is too early to discern the medium- and longer-term consequences of COVID-19 for defence ministries, but a greater focus on societal resilience and reinvigorating economic productivity will likely undercut the rationale for expensive nuclear modernization.

Therefore, extending the current New START (Strategic Arms Reduction Treaty) would be the best, most practical option to give both Russia and the United States time to explore more ambitious multilateral arms control measures, while allowing their current focus to remain on the pandemic and economic relief.

Continuing distrust

But with the current treaty — which limits nuclear warheads, missiles, bombers, and launchers — due to expire in February 2021, the continuing distrust between the United States and Russia makes this extension hard to achieve, and a follow-on treaty even less likely.

Prospects for future bilateral negotiations are hindered by President Donald Trump’s vision for a trilateral arms control initiative involving both China and Russia. But China opposes this on the grounds that its nuclear arsenal is far smaller than that of the two others.

While there appears to be agreement that the nuclear arsenals of China, France, and the UK (the NPT nuclear-weapons states) and those of the states outside the treaty (India, Pakistan, North Korea, and Israel) will all have to be taken into account going forward, a practical mechanism for doing so proves elusive.

If Joe Biden wins the US presidency he seems likely to pursue an extension of the New START treaty and could also prevent a withdrawal from the Open Skies treaty, the latest arms control agreement targeted by the Trump administration.

Under a Biden administration, the United States would also probably re-join the JCPOA, provided Tehran returned to strict compliance with the deal. Biden could even use the team that negotiated the Iran deal to advance the goal of denuclearization of the Korean peninsula.

For an NPT regime already confronted by a series of longstanding divergences, it is essential that Iran remains a signatory especially as tensions between Iran and the United States have escalated recently — due to the Qassim Suleimani assassination and the recent claim by Iran’s Revolutionary Guard Corps to have successfully placed the country’s first military satellite into orbit.

This announcement raised red flags among experts about whether Iran is developing intercontinental ballistic missiles due to the dual-use nature of space technology. The satellite launch — deeply troubling for Iran’s neighbours and the EU countries — may strengthen the US argument that it is a cover for the development of ballistic missiles capable of delivering nuclear weapons.

However, as with many other countries, Iran is struggling with a severe coronavirus crisis and will be pouring its scientific expertise and funds into that rather than other efforts — including the nuclear programme.

Those European countries supporting the trading mechanism INSTEX (Instrument in Support of Trade Exchanges) for sending humanitarian goods into Iran could use this crisis to encourage Iran to remain in compliance with the JCPOA and its NPT obligations.

France, Germany and the UK (the E3) have already successfully concluded the first transaction, which was to facilitate the export of medical goods from Europe to Iran. But the recent Iranian escalatory steps will most certainly place a strain on the preservation of this arrangement.

COVID-19 might have delayed Iran’s next breach of the 2015 nuclear agreement but Tehran will inevitably seek to strengthen its hand before any potential negotiations with the United States after the presidential elections.

As frosty US-Iranian relations — exacerbated by the coronavirus pandemic — prevent diplomatic negotiations, this constructive engagement between the E3 and Iran might prove instrumental in reviving the JCPOA and ensuring Iran stays committed to both nuclear non-proliferation and disarmament.

While countries focus their efforts on tackling the coronavirus pandemic, it is understandable resources may be limited for other global challenges, such as the increasing risk of nuclear weapons use across several regions.

But the potential ramifications of the COVID-19 crisis for the NPT regime are profound. Ongoing tensions between the nuclear-armed states must not be ignored while the world’s focus is elsewhere, and the nuclear community should continue to work together to progress nuclear non-proliferation and disarmament, building bridges of cooperation and trust that can long outlast the pandemic.

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.

Tacrolimus-Induced BMP/SMAD Signaling Associates With Metabolic Stress-Activated FOXO1 to Trigger {beta}-Cell Failure

Active maintenance of β-cell identity through fine-tuned regulation of key transcription factors ensures β-cell function. Tacrolimus, a widely used immunosuppressant, accelerates onset of diabetes after organ transplantation, but underlying molecular mechanisms are unclear. Here we show that tacrolimus induces loss of human β-cell maturity and β-cell failure through activation of the BMP/SMAD signaling pathway when administered under mild metabolic stress conditions. Tacrolimus-induced phosphorylated SMAD1/5 acts in synergy with metabolic stress–activated FOXO1 through formation of a complex. This interaction is associated with reduced expression of the key β-cell transcription factor MAFA and abolished insulin secretion, both in vitro in primary human islets and in vivo in human islets transplanted into high-fat diet–fed mice. Pharmacological inhibition of BMP signaling protects human β-cells from tacrolimus-induced β-cell dysfunction in vitro. Furthermore, we confirm that BMP/SMAD signaling is activated in protocol pancreas allograft biopsies from recipients on tacrolimus. To conclude, we propose a novel mechanism underlying the diabetogenicity of tacrolimus in primary human β-cells. This insight could lead to new treatment strategies for new-onset diabetes and may have implications for other forms of diabetes.
