lec Mutation of an atypical oxirane oxyanion hole improves regioselectivity of the {alpha}/{beta}-fold epoxide hydrolase Alp1U [Enzymology] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 Epoxide hydrolases (EHs) have been characterized and engineered as biocatalysts that convert epoxides to valuable chiral vicinal diol precursors of drugs and bioactive compounds. Nonetheless, the regioselectivity control of the epoxide ring opening by EHs remains challenging. Alp1U is an α/β-fold EH that exhibits poor regioselectivity in the epoxide hydrolysis of fluostatin C (compound 1) and produces a pair of stereoisomers. Herein, we established the absolute configuration of the two stereoisomeric products and determined the crystal structure of Alp1U. A Trp-186/Trp-187/Tyr-247 oxirane oxygen hole was identified in Alp1U that replaced the canonical Tyr/Tyr pair in α/β-EHs. Mutation of residues in the atypical oxirane oxygen hole of Alp1U improved the regioselectivity for epoxide hydrolysis on 1. The single site Y247F mutation led to highly regioselective (98%) attack at C-3 of 1, whereas the double mutation W187F/Y247F resulted in regioselective (94%) nucleophilic attack at C-2. Furthermore, single-crystal X-ray structures of the two regioselective Alp1U variants in complex with 1 were determined. These findings allowed insights into the reaction details of Alp1U and provided a new approach for engineering regioselective epoxide hydrolases. Full Article

lec Calpain activation mediates microgravity-induced myocardial abnormalities in mice via p38 and ERK1/2 MAPK pathways [Molecular Bases of Disease] By www.jbc.org Published On :: 2020-12-04T00:06:06-08:00 The human cardiovascular system has adapted to function optimally in Earth's 1G gravity, and microgravity conditions cause myocardial abnormalities, including atrophy and dysfunction. However, the underlying mechanisms linking microgravity and cardiac anomalies are incompletely understood. In this study, we investigated whether and how calpain activation promotes myocardial abnormalities under simulated microgravity conditions. Simulated microgravity was induced by tail suspension in mice with cardiomyocyte-specific deletion of Capns1, which disrupts activity and stability of calpain-1 and calpain-2, and their WT littermates. Tail suspension time-dependently reduced cardiomyocyte size, heart weight, and myocardial function in WT mice, and these changes were accompanied by calpain activation, NADPH oxidase activation, and oxidative stress in heart tissues. The effects of tail suspension were attenuated by deletion of Capns1. Notably, the protective effects of Capns1 deletion were associated with the prevention of phosphorylation of Ser-345 on p47phox and attenuation of ERK1/2 and p38 activation in hearts of tail-suspended mice. Using a rotary cell culture system, we simulated microgravity in cultured neonatal mouse cardiomyocytes and observed decreased total protein/DNA ratio and induced calpain activation, phosphorylation of Ser-345 on p47phox, and activation of ERK1/2 and p38, all of which were prevented by calpain inhibitor-III. Furthermore, inhibition of ERK1/2 or p38 attenuated phosphorylation of Ser-345 on p47phox in cardiomyocytes under simulated microgravity. This study demonstrates for the first time that calpain promotes NADPH oxidase activation and myocardial abnormalities under microgravity by facilitating p47phox phosphorylation via ERK1/2 and p38 pathways. Thus, calpain inhibition may be an effective therapeutic approach to reduce microgravity-induced myocardial abnormalities. Full Article
lec M8R tropomyosin mutation disrupts actin binding and filament regulation: The beginning affects the middle and end [Molecular Bases of Disease] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 Dilated cardiomyopathy (DCM) is associated with mutations in cardiomyocyte sarcomeric proteins, including α-tropomyosin. In conjunction with troponin, tropomyosin shifts to regulate actomyosin interactions. Tropomyosin molecules overlap via tropomyosin–tropomyosin head-to-tail associations, forming a continuous strand along the thin filament. These associations are critical for propagation of tropomyosin's reconfiguration along the thin filament and key for the cooperative switching between heart muscle contraction and relaxation. Here, we tested perturbations in tropomyosin structure, biochemistry, and function caused by the DCM-linked mutation, M8R, which is located at the overlap junction. Localized and nonlocalized structural effects of the mutation were found in tropomyosin that ultimately perturb its thin filament regulatory function. Comparison of mutant and WT α-tropomyosin was carried out using in vitro motility assays, CD, actin co-sedimentation, and molecular dynamics simulations. Regulated thin filament velocity measurements showed that the presence of M8R tropomyosin decreased calcium sensitivity and thin filament cooperativity. The co-sedimentation of actin and tropomyosin showed weakening of actin-mutant tropomyosin binding. The binding of troponin T's N terminus to the actin-mutant tropomyosin complex was also weakened. CD and molecular dynamics indicate that the M8R mutation disrupts the four-helix bundle at the head-to-tail junction, leading to weaker tropomyosin–tropomyosin binding and weaker tropomyosin–actin binding. Molecular dynamics revealed that altered end-to-end bond formation has effects extending toward the central region of the tropomyosin molecule, which alter the azimuthal position of tropomyosin, likely disrupting the mutant thin filament response to calcium. These results demonstrate that mutation-induced alterations in tropomyosin–thin filament interactions underlie the altered regulatory phenotype and ultimately the pathogenesis of DCM. Full Article
lec High affinity binding of SARS-CoV-2 spike protein enhances ACE2 carboxypeptidase activity [Molecular Bases of Disease] By www.jbc.org Published On :: 2020-12-25T00:06:31-08:00 The novel severe acute respiratory syndrome coronavirus (SARS-CoV-2) has emerged to a pandemic and caused global public health crisis. Human angiotensin-converting enzyme 2(ACE2) was identified as the entry receptor for SARS-CoV-2. As a carboxypeptidase, ACE2 cleaves many biological substrates besides angiotensin II to control vasodilatation and vascular permeability. Given the nanomolar high affinity between ACE2 and SARS-CoV-2 spike protein, we investigated how this interaction would affect the enzymatic activity of ACE2. Surprisingly, SARS-CoV-2 trimeric spike protein increased ACE2 proteolytic activity ∼3-10 fold against model peptide substrates, such as caspase-1 substrate and Bradykinin-analog. The enhancement in ACE2 enzymatic function was mediated by the binding of SARS-CoV-2 spike RBD domain. These results highlighted the potential for SARS-CoV-2 infection to enhance ACE2 activity, which may be relevant to the cardiovascular symptoms associated with COVID-19. Full Article
lec Naturally occurring hotspot cancer mutations in G{alpha}13 promote oncogenic signaling [Molecular Bases of Disease] By www.jbc.org Published On :: 2020-12-04T00:06:06-08:00 Heterotrimeric G-proteins are signaling switches broadly divided into four families based on the sequence and functional similarity of their Gα subunits: Gs, Gi/o, Gq/11, and G12/13. Artificial mutations that activate Gα subunits of each of these families have long been known to induce oncogenic transformation in experimental systems. With the advent of next-generation sequencing, activating hotspot mutations in Gs, Gi/o, or Gq/11 proteins have also been identified in patient tumor samples. In contrast, patient tumor-associated G12/13 mutations characterized to date lead to inactivation rather than activation. By using bioinformatic pathway analysis and signaling assays, here we identified cancer-associated hotspot mutations in Arg-200 of Gα13 (encoded by GNA13) as potent activators of oncogenic signaling. First, we found that components of a G12/13-dependent signaling cascade that culminates in activation of the Hippo pathway effectors YAP and TAZ is frequently altered in bladder cancer. Up-regulation of this signaling cascade correlates with increased YAP/TAZ activation transcriptional signatures in this cancer type. Among the G12/13 pathway alterations were mutations in Arg-200 of Gα13, which we validated to promote YAP/TAZ-dependent (TEAD) and MRTF-A/B-dependent (SRE.L) transcriptional activity. We further showed that this mechanism relies on the same RhoGEF-RhoGTPase cascade components that are up-regulated in bladder cancers. Moreover, Gα13 Arg-200 mutants induced oncogenic transformation in vitro as determined by focus formation assays. In summary, our findings on Gα13 mutants establish that naturally occurring hotspot mutations in Gα subunits of any of the four families of heterotrimeric G-proteins are putative cancer drivers.

lec Disease-associated mutations in inositol 1,4,5-trisphosphate receptor subunits impair channel function [Molecular Bases of Disease] By www.jbc.org Published On :: 2020-12-25T00:06:30-08:00 The inositol 1,4,5-trisphosphate (IP3) receptors (IP3Rs), which form tetrameric channels, play pivotal roles in regulating the spatiotemporal patterns of intracellular calcium signals. Mutations in IP3Rs have been increasingly associated with many debilitating human diseases such as ataxia, Gillespie syndrome, and generalized anhidrosis. However, how these mutations affect IP3R function, and how the perturbation of as-sociated calcium signals contribute to the pathogenesis and severity of these diseases remains largely uncharacterized. Moreover, many of these diseases occur as the result of autosomal dominant inheritance, suggesting that WT and mutant subunits associate in heterotetrameric channels. How the in-corporation of different numbers of mutant subunits within the tetrameric channels affects its activities and results in different disease phenotypes is also unclear. In this report, we investigated representative disease-associated missense mutations to determine their effects on IP3R channel activity. Additionally, we designed concatenated IP3R constructs to create tetrameric channels with a predefined subunit composition to explore the functionality of heteromeric channels. Using calcium imaging techniques to assess IP3R channel function, we observed that all the mutations studied resulted in severely attenuated Ca2+ release when expressed as homotetramers. However, some heterotetramers retained varied degrees of function dependent on the composition of the tetramer. Our findings suggest that the effect of mutations depends on the location of the mutation in the IP3R structure, as well as on the stoichiometry of mutant subunits assembled within the tetrameric channel. These studies provide insight into the pathogenesis and penetrance of these devastating human diseases. Full Article

Speakers explore policy opportunities to bridge the energy access gap, the key barriers that remain and the transformative potential of energy transition in delivering sustainable access for all. African countries face an uphill battle as they confront the shocks of the coronavirus pandemic, seeking recovery in the context of global socio-economic difficulty and fragmented geopolitics. With deficits in terms of governance, public health systems, social protection, and basic service delivery presenting challenges even before the outbreak, careful analysis and creative evidence-based policy solutions, as well as emphasis on implementation, will be crucial if Africa is to progress towards the SDGs and Agenda 2063. The Policy for Recovery in Africa series brings together expert speakers and decision makers to examine and exchange on key challenges, potential solutions, and approaches for implementation. The energy access gap in Africa presents one of the most serious obstacles to the long-term pandemic recovery effort, with almost half of the continent’s population estimated to still lack access to electricity, creating a negative annual GDP impact estimated to be over 25 billion USD.

lec Why America’s midterm elections matter for the world By www.chathamhouse.org Published On :: Wed, 28 Sep 2022 10:03:03 +0000 Why America’s midterm elections matter for the world The World Today mhiggins.drupal 28 September 2022 The outcome could threaten the fight against climate change and the future of democracy itself, warns Leslie Vinjamuri. As the November 8 midterm elections in the United States approach, the sense of urgency among the Democrats and Republicans is escalating. Early voter turnout is on track to surpass the 2018 midterms, when a record 122 million Americans voted ahead of election day. The midterms – when congressional, state and local seats are determined – used to pass almost unnoticed, especially outside the US. The midterms will be the first real litmus test for the continued relevance of Donald Trump and Trumpism Since 2018, though, they have become a matter of global concern. The 2022 midterm elections will be the first major elections in the US since the January 6 insurrection at the US Capitol. As such, they will be the first real litmus test for the continued relevance of Donald Trump and Trumpism. For both parties, winning is more important than ever and it is not only a matter of policy. Today, a majority of members of both parties – 72 per cent of Republicans and 63 per cent of Democrats – see those belonging to the opposing party as immoral, according to a Pew Research Center poll in September, representing a significant rise since 2016. In many states, the midterms will have a direct impact on the 2024 presidential elections, influencing who decides how voting takes place, how votes are counted and, especially, who controls the certification of election results. Given this context, the stakes in elections are especially high. The winners will have the upper hand not only in defining many procedural rules but also the values that constitute the nation, such as on abortion rights, education and healthcare. Republicans and Democrats align on most key foreign policy Though foreign policy will bear a strong resemblance to its former self even if Republicans gain a majority in the House of Representatives, as many anticipate, the outcome of the elections on US global influence could impact efforts to combat climate change and to support the defence of Ukraine. The Republican Party has become known for its embrace of climate deniers and the radicalized anti-immigrant rhetoric of many of its party’s most established figures. The failure to address rampant gun violence – and, instead, to defend a historically suspect interpretation of the right to bear arms – and the push for a national abortion ban mean that the party is imposing a version of America onto itself that is out-of-step with virtually all other rich democratic countries. The choices voters make in November are likely to shape the values that come to the fore in the US, and with this the affinity that America’s closest partners feel for it. Domestic policy is likely to be more heavily affected by the elections. A Republican majority in the House would stall progress on President Joe Biden’s domestic agenda and undercut his ability to raise the taxes he needs to pay for his spending plans. The drive to hold the former President Trump accountable will also be affected by the choices voters make in November. A Republican majority in the House would spell an end to congressional investigations of Donald Trump A Republican majority in the House would spell an end to congressional investigations of Donald Trump. Instead, Republicans would use their electoral gains to launch their investigations into the Democrats. One anti-Trump Republican on the January 6 committee investigating the storming of the Capitol building last year warned of a vengeful and obstructive turn against Biden from his Republican colleagues if they took the House. ‘They’re going to demand an impeachment vote on President Biden every week,’ said congressman Adam Kinzinger. It is under this shadow that the January 6 Committee is pressing ahead to finish its proceedings and publish its report. On foreign policy, the parties are more aligned than divided on most of the key issues. Their differences are a matter of diplomacy, which matters, and degree. Support for Ukraine has had bipartisan backing, but in recent weeks the issue has become politicized. Some congressional Republicans are more hawkish than their Democratic counterparts in their ambition to support Ukraine. Yet, the congressman set to be Speaker of the House if Republicans gain a majority, Kevin McCarthy, is leading an effort to exercise far stronger oversight of any additional funds for Ukraine. Ultimately, though, the president and his advisers maintain considerable control over foreign policy. Bipartisan support for a tougher stance on China was consolidated under Trump. He mobilized US voters by blaming China for the loss of manufacturing jobs. Later he held China responsible for the outbreak of Covid and for covering it up. China’s crackdown on democracy in Hong Kong, its assertiveness in the South China Seas, tensions over Taiwan and reports of human rights abuse against the Uighur in Xinjiang have cemented a bipartisan consensus on America’s China policy. But a more empowered Republican base looks likely to lead to a more ideologically driven anti-China rhetoric. The ground has also shifted over Russia. During President Trump’s tenure, Republican attitudes towards Vladimir Putin softened. But the Russian president’s aggressive invasion of Ukraine has entrenched American opposition to him and bolstered support for NATO. Democrats and Republicans are also more aligned on policy towards Iran today than they were before Trump abandoned the Iran Deal negotiating the Middle Eastern country’s nuclear programme. On some contentious issues, such as immigration reform, progress is already stalled and that is unlikely to change. US climate change policy may depend on the results The upshot of all this is that the president is unlikely to make radical changes to US foreign policy regardless of the results of the midterms. The most important exception to this is climate change, which continues to be the unwanted stepchild of the Republican Party. Domestic infighting in the US would inevitably detract even further from the bold policy that is needed. Republicans are unlikely to get the two-thirds majority needed to pass legislation that would undermine President Biden’s climate bill. Republican control of House committees, however, would add more politically driven oversight of any climate spending, including what has already been authorized by the Inflation Reduction Act. Policy convergence and clear executive authority cannot mitigate the sheer disruption that would be unleashed if the Republicans were to gain majorities in both the Senate and the House, however. For the rest of the world, and especially within Europe, this would send warning signs about the future trajectory of US foreign policy commitments and set off alarm bells that an ‘America First’ president might return to the White House after 2024. Especially within Europe, Republican victories would send warning signs about future US foreign policy A Republican majority in the House with a Democratic majority in the Senate would be disruptive, if less so, but would probably spell the end of business as usual, unsettling people, states and markets. All of this is unfolding at a time when many of the world’s rich democracies face internal divisions, rising inequality and populist challenges at home and so are ill-equipped to lead. Democracies face a trust deficit. This is especially apparent in the US where only 43 per cent of Americans have trust in US institutions, according to the 2022 Edelman Trust Barometer. Internal threats to democracy also unsettle the promise of US global leadership at a time when concerted and determined leadership is needed to maintain a strong and united response to Russia, and to tackle global food insecurity and the energy, climate and debt crises. In addition, the failure to lead a global response that can help developing countries is feeding a trust deficit between rich and poor countries. The midterms will reveal a greater truth about the future of the Republican Party. Even more so, it will reveal the values held by the American electorate. In the run-up to the 2020 US presidential elections, Europeans frequently said that they would not give Americans a pass if they voted for Donald Trump twice – and indeed only 17 per cent of those in European Union countries would have cast a vote for Trump if they could. A Republican midterm victory in both the Senate and the House of Representatives would have ripple effects across the Atlantic at a time when the threat from Russia has intensified. The US is judged around the world for what it does, but also for who it is. The perception that democracy is failing in America creates a permissive environment for aspiring autocrats. At a time when democracy has been in decline around the world for more than 15 years, it is essential that the US fix its own democracy and that it demonstrates to the rest of the world that democracy can deliver. The midterms will signal to the world what Americans value, sending a message about what it can expect from the US. This article was updated on October 31, 2022 to reflect developments such as early voting turnout, and the impact of the midterms on the 2024 presidential election, support for Ukraine and climate change spending.

lec Reflections on Iraq since 2003 By www.chathamhouse.org Published On :: Mon, 20 Feb 2023 13:42:13 +0000 Reflections on Iraq since 2003 6 March 2023 — 11:00AM TO 12:15PM Anonymous (not verified) 20 February 2023 Chatham House This event reflects on the legacy of the invasion and occupation for Iraq, the Middle East, and the West. When a US-led coalition invaded Iraq and overthrew the Saddam Hussein regime 20 years ago, many Iraqis hoped that a more democratic, prosperous future lay ahead. But in reality, their lives have been marred by different forms of violent conflict, fuelled by a corrupt system through which a new class of leaders gutted state finances and enriched themselves at the expense of the people. Today, almost two-thirds of the Iraqi population are under 25 and have no memory of life under Saddam Hussein. For many, the legacy of the war is only a failed political system that kills every day by means of corruption and neglect. At this roundtable, part of the Iraq Initiative, Chatham House welcomes journalist and author Ghaith Abdul-Ahad to discuss his book on this subject, called A Stranger in Your Own City: Travels in the Middle East’s Long War, alongside a panel of experts who will explore the profound legacy of the war for the Iraqi people. This marks the first in a series of Chatham House Iraq Initiative events and analysis reflecting on the legacy of the invasion and occupation for Iraq, the Middle East and the West. Full Article
