mali 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

mali Amyloid precursor protein is a restriction factor that protects against Zika virus infection in mammalian brains [Gene Regulation] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 Zika virus (ZIKV) is a neurotropic flavivirus that causes several diseases including birth defects such as microcephaly. Intrinsic immunity is known to be a frontline defense against viruses through host anti-viral restriction factors. Limited knowledge is available on intrinsic immunity against ZIKV in brains. Amyloid precursor protein (APP) is predominantly expressed in brains and implicated in the pathogenesis of Alzheimer's diseases. We have found that ZIKV interacts with APP, and viral infection increases APP expression via enhancing protein stability. Moreover, we identified the viral peptide, HGSQHSGMIVNDTGHETDENRAKVEITPNSPRAEATLGGFGSLGL, which is capable of en-hancing APP expression. We observed that aging brain tissues with APP had protective effects on ZIKV infection by reducing the availability of the viruses. Also, knockdown of APP expression or blocking ZIKV-APP interactions enhanced ZIKV replication in human neural progenitor/stem cells. Finally, intracranial infection of ZIKV in APP-null neonatal mice resulted in higher mortality and viral yields. Taken together, these findings suggest that APP is a restriction factor that protects against ZIKV by serving as a decoy receptor, and plays a protective role in ZIKV-mediated brain injuries.

mali Stop codon read-through of mammalian MTCH2 leading to an unstable isoform regulates mitochondrial membrane potential [Gene Regulation] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 Stop codon read-through (SCR) is a process of continuation of translation beyond a stop codon. This phenomenon, which occurs only in certain mRNAs under specific conditions, leads to a longer isoform with properties different from that of the canonical isoform. MTCH2, which encodes a mitochondrial protein that regulates mitochondrial metabolism, was selected as a potential read-through candidate based on evolutionary conservation observed in the proximal region of its 3' UTR. Here, we demonstrate translational read-through across two evolutionarily conserved, in-frame stop codons of MTCH2 using luminescence- and fluorescence-based assays, and by analyzing ribosome-profiling and mass spectrometry (MS) data. This phenomenon generates two isoforms, MTCH2x and MTCH2xx (single- and double-SCR products, respectively), in addition to the canonical isoform MTCH2, from the same mRNA. Our experiments revealed that a cis-acting 12-nucleotide sequence in the proximal 3' UTR of MTCH2 is the necessary signal for SCR. Functional characterization showed that MTCH2 and MTCH2x were localized to mitochondria with a long t1/2 (>36 h). However, MTCH2xx was found predominantly in the cytoplasm. This mislocalization and its unique C terminus led to increased degradation, as shown by greatly reduced t1/2 (<1 h). MTCH2 read-through–deficient cells, generated using CRISPR-Cas9, showed increased MTCH2 expression and, consistent with this, decreased mitochondrial membrane potential. Thus, double-SCR of MTCH2 regulates its own expression levels contributing toward the maintenance of normal mitochondrial membrane potential. Full Article

mali Development of a novel mammalian display system for selection of antibodies against membrane proteins [Immunology] By www.jbc.org Published On :: 2020-12-25T00:06:31-08:00 Reliable, specific polyclonal and monoclonal antibodies are important tools in research and medicine. However, the discovery of antibodies against their targets in their native forms is difficult. Here, we present a novel method for discovery of antibodies against membrane proteins in their native configuration in mammalian cells. The method involves the co-expression of an antibody library in a population of mammalian cells that express the target polypeptide within a natural membrane environment on the cell surface. Cells that secrete a single-chain fragment variable (scFv) that binds to the target membrane protein thereby become self-labeled, enabling enrichment and isolation by magnetic sorting and FRET-based flow sorting. Library sizes of up to 109 variants can be screened, thus allowing campaigns of naïve scFv libraries to be selected against membrane protein antigens in a Chinese hamster ovary cell system. We validate this method by screening a synthetic naïve human scFv library against Chinese hamster ovary cells expressing the oncogenic target epithelial cell adhesion molecule and identify a panel of three novel binders to this membrane protein, one with a dissociation constant (KD) as low as 0.8 nm. We further demonstrate that the identified antibodies have utility for killing epithelial cell adhesion molecule–positive cells when used as a targeting domain on chimeric antigen receptor T cells. Thus, we provide a new tool for identifying novel antibodies that act against membrane proteins, which could catalyze the discovery of new candidates for antibody-based therapies. Full Article
mali Why the Mali Coup Should Matter to the UK By www.chathamhouse.org Published On :: Thu, 20 Aug 2020 09:24:41 +0000 20 August 2020 Dr Alex Vines OBE Managing Director, Ethics, Risk & Resilience; Director, Africa Programme This coup was not unexpected as it followed months of mass protests against alleged corruption, a worsening economy and disputed elections. 2020-08-20-Mali-Coup-Military Press conference in Kati after the military arrested Malian president Ibrahim Boubacar Keita and he officially resigned. Photo by ANNIE RISEMBERG / AFP via Getty Images. The coup in Mali is not a putsch by disgruntled soldiers in a distant land. It is an extended European neighbourhood and matters to Britain. The UK already has three Chinook helicopters deployed in country and 250 British troops are scheduled to take up UN peacekeeping duties in December in what could be the ministry of defence’s most dangerous deployment since Afghanistan.This coup was not unexpected as it followed months of mass protests against alleged corruption, a worsening economy, disputed legislative election results and deteriorating security in this West African country. Mali’s military is struggling to stop the insurgents, some of them now also affiliated with the ISIL (ISIS) armed group, despite UN, EU, French and regional military support.The departure of Mali's President Ibrahim Boubacar Keita was met with jubilation by anti-government demonstrators in Bamako and the leaders of the military coup say they would enact a political transition and stage elections within a 'reasonable time'.Coups, followed by transitional arrangements and then new elections, are not rare in this region and have happened before in Mali when Keita’s predecessor Amadou Toumani Toure was overthrown by the military in 2012. The current cycle of insecurity followed despite a significant military intervention by France to restore elected government and stop the spread of Islamic extremist insurgency.This is a reminder of how fragile the Sahel regon is and the importance of seeking stability and state building in a region of spreading Islamic extremist insurgency and rapidly-eroding state legitimacy.The regional bloc ECOWAS (Economic Community of West African States) has denounced the coup and ordered the closing of regional borders with Mali as well as the suspension of all financial flows between Mali and its 15 members states. What follows now will be negotiations over the transitional arrangements and the timetable for new elections.This will not be straightforward. Although the opposition was united in their demand for Keita's resignation there is little consensus on what to do next, while the UN Security Council and ECOWAS are divided on how to respond beyond initial condemnation.It is urgent that three UK cabinet ministers, led by the first secretary of state Dominic Raab, who are currently reviewing the UK’s Sahel strategy complete this and decide upon its future direction.The UK government needs crystal clarity on its Mali objectives as the clock ticks down to the deployment of British troops there. Increasingly this UN duty looks to become more peacemaking than peacekeeping.This article was originally published in The Telegraph. Full Article

Key issues for the new administration are a deteriorating situation with regards to drought as close to half the population are facing food insecurity due to a fourth failed rainy season. Combined with an inflation rate above ten per cent, many Somalis are at risk of famine and starvation. Many areas of the country are affected from the pastoralist regions to those which house IDP camps around the capital city and other towns, all being exacerbated by the war in Ukraine as Somalia was importing much of its wheat imports from Ukraine and Russia.

mali Dietary sphinganine is selectively assimilated by members of the mammalian gut microbiome [Research Articles] By www.jlr.org Published On :: 2020-07-09T14:33:39-07:00 Functions of the gut microbiome have a growing number of implications for host metabolic health, with diet being one of the most significant influences on microbiome composition. Compelling links between diet and the gut microbiome suggest key roles for various macronutrients, including lipids, yet how individual classes of dietary lipids interact with the microbiome remains largely unknown. Sphingolipids are bioactive components of most foods and are also produced by prominent gut microbes. This makes sphingolipids intriguing candidates for shaping diet–microbiome interactions. Here, we used a click chemistry–based approach to track the incorporation of bioorthogonal dietary omega-alkynyl sphinganine (sphinganine alkyne [SAA]) into the murine gut microbial community (Bioorthogonal labeling). We identified microbial and SAA-specific metabolic products through fluorescence-based sorting of SAA-containing microbes (Sort), 16S rRNA gene sequencing to identify the sphingolipid-interacting microbes (Seq), and comparative metabolomics to identify products of SAA assimilation by the microbiome (Spec). Together, this approach, termed Bioorthogonal labeling-Sort-Seq-Spec (BOSSS), revealed that SAA assimilation is nearly exclusively performed by gut Bacteroides, indicating that sphingolipid-producing bacteria play a major role in processing dietary sphinganine. Comparative metabolomics of cecal microbiota from SAA-treated mice revealed conversion of SAA to a suite of dihydroceramides, consistent with metabolic activities of Bacteroides and Bifidobacterium. Additionally, other sphingolipid-interacting microbes were identified with a focus on an uncharacterized ability of Bacteroides and Bifidobacterium to metabolize dietary sphingolipids. We conclude that BOSSS provides a platform to study the flux of virtually any alkyne-labeled metabolite in diet–microbiome interactions. Full Article
mali Transcriptome and secretome analysis of intra-mammalian life-stages of the emerging helminth pathogen, Calicophoron daubneyi reveals adaptation to a unique host environment. [Research] By www.mcponline.org Published On :: 2020-10-20T14:35:18-07:00 Paramphistomosis, caused by the rumen fluke, Calicophoron daubneyi, is a parasitic infection of ruminant livestock which has seen a rapid rise in prevalence throughout Western Europe in recent years. Following ingestion of metacercariae (parasite cysts) by the mammalian host, newly-excysted juveniles (NEJs) emerge and invade the duodenal submucosa which causes significant pathology in heavy infections. The immature larvae then migrate upwards, along the gastrointestinal tract, and enter the rumen where they mature and begin to produce eggs. Despite their emergence, and sporadic outbreaks of acute disease, we know little about the molecular mechanisms used by C. daubneyi to establish infection, acquire nutrients and to avoid the host immune response. Here, transcriptome analysis of four intra-mammalian life-cycle stages, integrated with secretome analysis of the NEJ and adult parasites (responsible for acute and chronic disease respectively), revealed how the expression and secretion of selected families of virulence factors and immunomodulators are regulated in accordance with fluke development and migration. Our data show that whilst a family of cathepsins B with varying S2 sub-site residues (indicating distinct substrate specificities) are differentially secreted by NEJs and adult flukes, cathepsins L and F are secreted in low abundance by NEJs only. We found that C. daubneyi has an expanded family of aspartic peptidases, which is up-regulated in adult worms, although they are underrepresented in the secretome. The most abundant proteins in adult fluke secretions were helminth defence molecules (HDMs) that likely establish an immune environment permissive to fluke survival and/or neutralise pathogen-associated molecular patterns (PAMPs) such as bacterial lipopolysaccharide in the microbiome-rich rumen. The distinct collection of molecules secreted by C. daubneyi allowed the development of the first coproantigen-based ELISA for paramphistomosis which, importantly, did not recognise antigens from other helminths commonly found as co-infections with rumen fluke.

Weaponizing data, ransomware attacks and other illicit cyber activity represent significant threats to national security. Governments and malicious cyber actors around the world exploit disruptive technology to engage in criminal activity, track citizens and coerce other countries thereby weakening the rules-based order and fundamental principles of democracy. Lisa Monaco discusses how the world is at an inflection point when it comes to meeting this challenge and describes how the US and partner nations are responding to protect their citizens and the broader international community. Key questions to discuss include: What steps does the US government need to take to properly address this threat? How are countries coordinating policies to confront the problem? To what extent does this challenge go beyond US-China competition? As with all member events, questions from the audience drive the conversation. Read the transcript. Full Article
