The rise of drug-resistant tuberculosis poses a major risk to public health. Statins, which inhibit both cholesterol biosynthesis and protein prenylation branches of the mevalonate pathway, increase anti-tubercular antibiotic efficacy in animal models. However, the underlying molecular mechanisms are unknown. In this study, we used an in vitro macrophage infection model to investigate simvastatin’s anti-tubercular activity by systematically inhibiting each branch of the mevalonate pathway and evaluating the effects of the branch-specific inhibitors on mycobacterial growth. The anti-tubercular activity of simvastatin used at clinically relevant doses specifically targeted the cholesterol biosynthetic branch rather than the prenylation branches of the mevalonate pathway. Using Western blot analysis and AMP/ATP measurements, we found that simvastatin treatment blocked activation of mechanistic target of rapamycin complex 1 (mTORC1), activated AMP-activated protein kinase (AMPK) through increased intracellular AMP:ATP ratios, and favored nuclear translocation of transcription factor EB (TFEB). These mechanisms all induce autophagy, which is anti-mycobacterial. The biological effects of simvastatin on the AMPK-mTORC1-TFEB-autophagy axis were reversed by adding exogenous cholesterol to the cells. Our data demonstrate that the anti-tubercular activity of simvastatin requires inhibiting cholesterol biosynthesis, reveal novel links between cholesterol homeostasis, the AMPK-mTORC1-TFEB axis, and Mycobacterium tuberculosis infection control, and uncover new anti-tubercular therapy targets.

Ion mobility brings an additional dimension of separation to LC–MS, improving identification of peptides and proteins in complex mixtures. A recently introduced timsTOF mass spectrometer (Bruker) couples trapped ion mobility separation to TOF mass analysis. With the parallel accumulation serial fragmentation (PASEF) method, the timsTOF platform achieves promising results, yet analysis of the data generated on this platform represents a major bottleneck. Currently, MaxQuant and PEAKS are most used to analyze these data. However, because of the high complexity of timsTOF PASEF data, both require substantial time to perform even standard tryptic searches. Advanced searches (e.g. with many variable modifications, semi- or non-enzymatic searches, or open searches for post-translational modification discovery) are practically impossible. We have extended our fast peptide identification tool MSFragger to support timsTOF PASEF data, and developed a label-free quantification tool, IonQuant, for fast and accurate 4-D feature extraction and quantification. Using a HeLa data set published by Meier et al. (2018), we demonstrate that MSFragger identifies significantly (~30%) more unique peptides than MaxQuant (1.6.10.43), and performs comparably or better than PEAKS X+ (~10% more peptides). IonQuant outperforms both in terms of number of quantified proteins while maintaining good quantification precision and accuracy. Runtime tests show that MSFragger and IonQuant can fully process a typical two-hour PASEF run in under 70 min on a typical desktop (6 CPU cores, 32 GB RAM), significantly faster than other tools. Finally, through semi-enzymatic searching, we significantly increase the number of identified peptides. Within these semi-tryptic identifications, we report evidence of gas-phase fragmentation before MS/MS analysis.

Communication between individuals via molecules, termed chemosignaling, is widespread among animal and plant species. However, we lack knowledge on the specific functions of the substances involved for most systems. The femoral gland is an organ that secretes a waxy substance involved in chemical communication in lizards. Although the lipids and volatile substances secreted by the femoral glands have been investigated in several biochemical studies, the protein composition and functions of secretions remain completely unknown. Applying a proteomic approach, we provide the first attempt to comprehensively characterize the protein composition of femoral gland secretions from the Galápagos marine iguana. Using samples from several organs, the marine iguana proteome was assembled by next-generation sequencing and MS, resulting in 7513 proteins. Of these, 4305 proteins were present in the femoral gland, including keratins, small serum proteins, and fatty acid-binding proteins. Surprisingly, no proteins with discernible roles in partner recognition or inter-species communication could be identified. However, we did find several proteins with direct associations to the innate immune system, including lysozyme C, antileukoproteinase (ALP), pulmonary surfactant protein (SFTPD), and galectin (LGALS1) suggesting that the femoral glands function as an important barrier to infection. Furthermore, we report several novel anti-microbial peptides from the femoral glands that show similar action against Escherichia coli and Bacillus subtilis such as oncocin, a peptide known for its effectiveness against Gram-negative pathogens. This proteomics data set is a valuable resource for future functional protein analysis and demonstrates that femoral gland secretions also perform functions of the innate immune system.

As the COVID-19 pandemic continues to spread, thousands of scientists around the globe have changed research direction to understand better how the virus works and to find out how it may be tackled. The number of manuscripts on preprint servers is soaring and peer-reviewed publications using MS-based proteomics are beginning to emerge. To facilitate proteomic research on SARS-CoV-2, the virus that causes COVID-19, this report presents deep-scale proteomes (10,000 proteins; >130,000 peptides) of common cell line models, notably Vero E6, Calu-3, Caco-2, and ACE2-A549 that characterize their protein expression profiles including viral entry factors such as ACE2 or TMPRSS2. Using the 9 kDa protein SRP9 and the breast cancer oncogene BRCA1 as examples, we show how the proteome expression data can be used to refine the annotation of protein-coding regions of the African green monkey and the Vero cell line genomes. Monitoring changes of the proteome on viral infection revealed widespread expression changes including transcriptional regulators, protease inhibitors, and proteins involved in innate immunity. Based on a library of 98 stable-isotope labeled synthetic peptides representing 11 SARS-CoV-2 proteins, we developed PRM (parallel reaction monitoring) assays for nano-flow and micro-flow LC–MS/MS. We assessed the merits of these PRM assays using supernatants of virus-infected Vero E6 cells and challenged the assays by analyzing two diagnostic cohorts of 24 (+30) SARS-CoV-2 positive and 28 (+9) negative cases. In light of the results obtained and including recent publications or manuscripts on preprint servers, we critically discuss the merits of MS-based proteomics for SARS-CoV-2 research and testing.

In-depth coverage of proteomic analysis could enhance our understanding to the mechanism of the protein functions. Unfortunately, many highly hydrophobic proteins and low-abundance proteins, which play critical roles in signaling networks, are easily lost during sample preparation, mainly attributed to the fact that very few extractants can simultaneously satisfy the requirements on strong solubilizing ability to membrane proteins and good enzyme compatibility. Thus, it is urgent to screen out ideal extractant from the huge compound libraries in a fast and effective way. Herein, by investigating the interior mechanism of extractants on the membrane proteins solubilization and trypsin compatibility, a molecular dynamics simulation system was established as complement to the experimental procedure to narrow down the scope of candidates for proteomics analysis. The simulation data shows that the van der Waals interaction between cation group of ionic liquid and membrane protein is the dominant factor in determining protein solubilization. In combination with the experimental data, 1-dodecyl-3-methylimidazolium chloride (C12Im-Cl) is on the shortlist for the suitable candidates from comprehensive aspects. Inspired by the advantages of C12Im-Cl, an ionic liquid-based filter-aided sample preparation (i-FASP) method was developed. Using this strategy, over 3,300 proteins were confidently identified from 10³ HeLa cells (~100 ng proteins) in a single run, an improvement of 53% over the conventional FASP method. Then the i-FASP method was further successfully applied to the label-free relative quantitation of human liver cancer and para-carcinoma tissues with obviously improved accuracy, reproducibility and coverage than the commonly used urea-based FASP method. The above results demonstrated that the i-FASP method could be performed as a versatile tool for the in-depth coverage proteomic analysis of biological samples.

Natural compounds that can stimulate salivary secretion are of interest in developing treatments for xerostomia, the perception of a dry mouth, that affects between 10 and 30% of the adult and elderly population. Chemesthetic transient receptor potential (TRP) channels are expressed in the surface of the oral mucosa. The TRPV1 agonists capsaicin and piperine have been shown to increase salivary flow when introduced into the oral cavity but the sialogogic properties of other TRP channel agonists have not been investigated. In this study we have determined the influence of different TRP channel agonists on the flow and protein composition of saliva. Mouth rinsing with the TRPV1 agonist nonivamide or menthol, a TRPM8 agonist, increased whole mouth saliva (WMS) flow and total protein secretion compared with unstimulated saliva, the vehicle control mouth rinse or cinnamaldehyde, a TRPA1 agonist. Nonivamide also increased the flow of labial minor gland saliva but parotid saliva flow rate was not increased. The influence of TRP channel agonists on the composition and function of the salivary proteome was investigated using a multi-batch quantitative MS method novel to salivary proteomics. Inter-personal and inter-mouth rinse variation was observed in the secreted proteomes and, using a novel bioinformatics method, inter-day variation was identified with some of the mouth rinses. Significant changes in specific salivary proteins were identified after all mouth rinses. In the case of nonivamide, these changes were attributed to functional shifts in the WMS secreted, primarily the over representation of salivary and nonsalivary cystatins which was confirmed by immunoassay. This study provides new evidence of the impact of TRP channel agonists on the salivary proteome and the stimulation of salivary secretion by a TRPM8 channel agonist, which suggests that TRP channel agonists are potential candidates for developing treatments for sufferers of xerostomia.

After ejaculation, mammalian spermatozoa must undergo a process known as capacitation in order to successfully fertilize the oocyte. Several post-translational modifications occur during capacitation, including sialylation, which despite being limited to a few proteins, seems to be essential for proper sperm-oocyte interaction. Regardless of its importance, to date, no single study has ever identified nor quantified which glycoproteins bearing terminal sialic acid (Sia) are altered during capacitation. Here we characterize sialylation during mouse sperm capacitation. Using tandem MS coupled with liquid chromatography (LC–MS/MS), we found 142 nonreductant peptides, with 9 of them showing potential modifications on their sialylated oligosaccharides during capacitation. As such, N-linked sialoglycopeptides from C4b-binding protein, endothelial lipase (EL), serine proteases 39 and 52, testis-expressed protein 101 and zonadhesin were reduced following capacitation. In contrast, mitochondrial aconitate hydratase (aconitase; ACO2), a TCA cycle enzyme, was the only protein to show an increase in Sia content during capacitation. Interestingly, although the loss of Sia within EL (N62) was accompanied by a reduction in its phospholipase A₁ activity, a decrease in the activity of ACO2 (i.e. stereospecific isomerization of citrate to isocitrate) occurred when sialylation increased (N612). The latter was confirmed by N612D recombinant protein tagged with both His and GFP. The replacement of Sia for the negatively charged Aspartic acid in the N612D mutant caused complete loss of aconitase activity compared with the WT. Computer modeling show that N612 sits atop the catalytic site of ACO2. The introduction of Sia causes a large conformational change in the alpha helix, essentially, distorting the active site, leading to complete loss of function. These findings suggest that the switch from oxidative phosphorylation, over to glycolysis that occurs during capacitation may come about through sialylation of ACO2.

Amino acid hydroxylation is a common post-translational modification, which generally regulates protein interactions or adds a functional group that can be further modified. Such hydroxylation is currently considered irreversible, necessitating the degradation and re-synthesis of the entire protein to reset the modification. Here we present evidence that the cellular machinery can reverse FIH-mediated asparagine hydroxylation on intact proteins. These data suggest that asparagine hydroxylation is a flexible and dynamic post-translational modification akin to modifications involved in regulating signaling networks, such as phosphorylation, methylation and ubiquitylation.

Coronavirus disease 2019 (COVID-19) is a highly contagious infection and threating the human lives in the world. The elevation of cytokines in blood is crucial to induce cytokine storm and immunosuppression in the transition of severity in COVID-19 patients. However, the comprehensive changes of serum proteins in COVID-19 patients throughout the SARS-CoV-2 infection is unknown. In this work, we developed a high-density antibody microarray and performed an in-depth proteomics analysis of serum samples collected from early COVID-19 (n = 15) and influenza (n = 13) patients. We identified a large set of differentially expressed proteins (n = 132) that participate in a landscape of inflammation and immune signaling related to the SARS-CoV-2 infection. Furthermore, the significant correlations of neutrophil and lymphocyte with the CCL2 and CXCL10 mediated cytokine signaling pathways was identified. These information are valuable for the understanding of COVID-19 pathogenesis, identification of biomarkers and development of the optimal anti-inflammation therapy.

Plasmodium, the malaria parasite, undergoes a complex life cycle alternating between a vertebrate host and a mosquito vector of the genus Anopheles. In red blood cells of the vertebrate host, Plasmodium multiplies asexually or differentiates into gamete precursors, the male and female gametocytes, responsible for parasite transmission. Sexual stage maturation occurs in the midgut of the mosquito vector, where male and female gametes egress from the host erythrocytes to fuse and form a zygote. Gamete egress entails the successive rupture of two membranes surrounding the parasite, the parasitophorous vacuole membrane and the erythrocyte plasma membrane. In this study, we used the rodent model parasite Plasmodium berghei to design a label-free quantitative proteomic approach aimed at identifying gender-related proteins differentially released/secreted by purified mature gametocytes when activated to form gametes. We compared the abundance of molecules secreted by wild type gametocytes of both genders with that of a transgenic line defective in male gamete maturation and egress. This enabled us to provide a comprehensive data set of egress-related molecules and their gender specificity. Using specific antibodies, we validated eleven candidate molecules, predicted as either gender-specific or common to both male and female gametocytes. All of them localize to punctuate, vesicle-like structures that relocate to cell periphery upon activation, but only three of them localize to the gametocyte-specific secretory vesicles named osmiophilic bodies. Our results confirm that the egress process involves a tightly coordinated secretory apparatus that includes different types of vesicles and may put the basis for functional studies aimed at designing novel transmission-blocking molecules.

Mallory-Denk-bodies (MDBs) are hepatic protein aggregates associated with inflammation both clinically and in MDB-inducing models. Similar protein aggregation in neurodegenerative diseases also triggers inflammation and NF-B activation. However, the precise mechanism that links protein aggregation to NF-B-activation and inflammatory response remains unclear. Herein we find that treating primary hepatocytes with MDB-inducing agents (N-methylprotoporphyrin (NMPP), protoporphyrin IX (PPIX), or Zinc-protoporphyrin IX (ZnPP)) elicited an IBα-loss with consequent NF-B activation. Four known mechanisms of IBα-loss i.e. the canonical ubiquitin-dependent proteasomal degradation (UPD), autophagic-lysosomal degradation, calpain degradation and translational inhibition, were all probed and excluded. Immunofluorescence analyses of ZnPP-treated cells coupled with 8 M urea/CHAPS-extraction revealed that this IBα-loss was due to its sequestration along with IBβ into insoluble aggregates, thereby releasing NF-B. Through affinity pulldown, proximity biotinylation by antibody recognition, and other proteomic analyses, we verified that NF-B subunit p65, which stably interacts with IBα under normal conditions, no longer binds to it upon ZnPP-treatment. Additionally, we identified 10 proteins that interact with IBα under baseline conditions, aggregate upon ZnPP-treatment, and maintain the interaction with IBα after ZnPP-treatment, either by cosequestering into insoluble aggregates or through a different mechanism. Of these 10 proteins, the nucleoporins Nup153 and Nup358/RanBP2 were identified through RNA-interference, as mediators of IBα-nuclear import. The concurrent aggregation of IBα, NUP153, and RanBP2 upon ZnPP-treatment, synergistically precluded the nuclear entry of IBα and its consequent binding and termination of NF-B activation. This novel mechanism may account for the protein aggregate-induced inflammation observed in liver diseases, thus identifying novel targets for therapeutic intervention. Because of inherent commonalities this MDB cell model is a bona fide protoporphyric model, making these findings equally relevant to the liver inflammation associated with clinical protoporphyria.

Glycosylation is a prevalent, yet heterogeneous modification with a broad range of implications in molecular biology. This heterogeneity precludes enrichment strategies that can be universally beneficial for all glycan classes. Thus, choice of enrichment strategy has profound implications on experimental outcomes. Here we review common enrichment strategies used in modern mass spectrometry (MS)-based glycoproteomic experiments, including lectins and other affinity chromatographies, hydrophilic interaction chromatography (HILIC) and its derivatives, porous graphitic carbon (PGC), reversible and irreversible chemical coupling strategies, and chemical biology tools that often leverage bioorthogonal handles. Interest in glycoproteomics continues to surge as MS instrumentation and software improve, so this review aims to help equip researchers with necessary information to choose appropriate enrichment strategies that best complement these efforts.

Esophageal squamous cell cancer (ESCC) is an aggressive malignancy with poor therapeutic outcomes. However, the alterations in proteins and post-translational modifications (PTMs) leading to the pathogenesis of ESCC remains unclear. Here, we provide the comprehensive characterization of the proteome, phosphorylome, lysine acetylome and succinylome for ESCC and matched control cells using quantitative proteomic approach. We identify abnormal protein and post-translational modification (PTM) pathways, including significantly downregulated lysine succinylation sites in cancer cells. Focusing on hyposuccinylation, we reveal that this altered PTM was enriched on enzymes of metabolic pathways inextricably linked with cancer metabolism. Importantly, ESCC malignant behaviors such as cell migration are inhibited once the level of succinylation was restored in vitro or in vivo. This effect was further verified by mutations to disrupt succinylation sites in candidate proteins. Meanwhile, we found that succinylation has a negative regulatory effect on histone methylation to promote cancer migration. Finally, hyposuccinylation is confirmed in primary ESCC specimens. Our findings together demonstrate that lysine succinylation may alter ESCC metabolism and migration, providing new insights into the functional significance of PTM in cancer biology.

The choice for adjuvant chemotherapy in stage II colorectal cancer (CRC) is controversial as many patients are cured by surgery alone and it is difficult to identify patients with high-risk of recurrence of the disease. There is a need for better stratification of this group of patients. Mass spectrometry imaging could identify patients at risk. We report here the N-glycosylation signatures of the different cell populations in a group of stage II CRC tissue samples. The cancer cells, compared to normal epithelial cells, have increased levels of sialylation and high-mannose glycans, as well as decreased levels of fucosylation and highly branched N-glycans. When looking at the interface between cancer and its microenvironment, it seems that the cancer N-glycosylation signature spreads into the surrounding stroma at the invasive front of the tumor. This finding was more outspoken in patients with a worse outcome within this sample group.

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.

The early detection of pancreatic ductal adenocarcinoma is a complex clinical obstacle yet is key to improving the overall likelihood of patient survival. Current and prospective carbohydrate biomarkers CA19-9 and sTRA are sufficient for surveilling disease progression yet are not approved for delineating PDAC from other abdominal cancers and non-cancerous pancreatic pathologies. To further understand these glycan epitopes, an imaging mass spectrometry approach was utilized to assess the N-glycome of the human pancreas and pancreatic cancer in a cohort of PDAC patients represented by tissue microarrays and whole tissue sections. Orthogonally, these same tissues were characterized by multi-round immunofluorescence which defined expression of CA19-9 and sTRA as well as other lectins towards carbohydrate epitopes with the potential to improve PDAC diagnosis. These analyses revealed distinct differences not only in N-glycan spatial localization across both healthy and diseased tissues but importantly between different biomarker-categorized tissue samples. Unique sulfated bi-antennary N-glycans were detected specifically in normal pancreatic islets. N-glycans from CA19-9 expressing tissues tended to be bi-, tri- and tetra-antennary structures with both core and terminal fucose residues and bisecting N-acetylglucosamines. These N-glycans were detected in less abundance in sTRA-expressing tumor tissues, which favored tri- and tetra-antennary structures with polylactosamine extensions. Increased sialylation of N-glycans was detected in all tumor tissues. A candidate new biomarker derived from IMS was further explored by fluorescence staining with selected lectins on the same tissues. The lectins confirmed the expression of the epitopes in cancer cells and revealed different tumor-associated staining patterns between glycans with bisecting GlcNAc and those with terminal GlcNAc. Thus, the combination of lectin-IHC and IMS techniques produces more complete information for tumor classification than the individual analyses alone. These findings potentiate the development of early assessment technologies to rapidly and specifically identify PDAC in the clinic that may directly impact patient outcomes.

The histopathological subtype of lung adenocarcinoma (LUAD) is closely associated with prognosis. Micropapillary or solid predominant LUAD tends to relapse after surgery at an early stage, whereas lepidic pattern shows a favorable outcome. However, the molecular mechanism underlying this phenomenon remains unknown. Here, we recruited 31 lepidic predominant LUADs (LR: low-risk subtype group) and 28 micropapillary or solid predominant LUADs (HR: high-risk subtype group). Tissues of these cases were obtained and label-free quantitative proteomic and bioinformatic analyses were performed. Additionally, prognostic impact of targeted proteins was validated using The Cancer Genome Atlas databases (n=492) and tissue microarrays composed of early-stage LUADs (n=228). A total of 192 differentially expressed proteins were identified between tumor tissues of LR and HR and three clusters were identified via hierarchical clustering excluding eight proteins. Cluster 1 (65 proteins) showed a sequential decrease in expression from normal tissues to tumor tissues of LR and then to HR and was predominantly enriched in pathways such as tyrosine metabolism and ECM-receptor interaction, and increased matched mRNA expression of 18 proteins from this cluster predicted favorable prognosis. Cluster 2 (70 proteins) demonstrated a sequential increase in expression from normal tissues to tumor tissues of LR and then to HR and was mainly enriched in pathways such as extracellular organization, DNA replication and cell cycle, and high matched mRNA expression of 25 proteins indicated poor prognosis. Cluster 3 (49 proteins) showed high expression only in LR, with high matched mRNA expression of 20 proteins in this cluster indicating favorable prognosis. Furthermore, high expression of ERO1A and FEN1 at protein level predicted poor prognosis in early-stage LUAD, supporting the mRNA results. In conclusion, we discovered key differentially expressed proteins and pathways between low-risk and high-risk subtypes of early-stage LUAD. Some of these proteins could serve as potential biomarkers in prognostic evaluation.

Deep proteome coverage in bottom-up proteomics requires peptide-level fractionation to simplify the complex peptide mixture before analysis by tandem mass spectrometry. By decreasing the number of co-eluting precursor peptide ions, fractionation effectively reduces the complexity of the sample leading to higher sample coverage and reduced bias towards high abundance precursors that are preferentially identified in data-dependent acquisition strategies. To achieve this goal, we report a bead-based off-line peptide fractionation method termed CIF or Carboxylate modified magnetic bead-based isopropanol gradient peptide fractionation. CIF is an extension of the SP3 (single-pot solid-phase-enhanced sample preparation) strategy and provides an effective but complementary approach to other commonly used fractionation methods including strong cation exchange (SCX) and reversed phase (RP)-based chromatography. We demonstrate that CIF is an effective offline separation strategy capable of increasing the depth of peptide analyte coverage both when used alone or as a second dimension of peptide fractionation in conjunction with high pH RP. These features make it ideally suited for a wide range of proteomic applications including the affinity purification of low abundance bait proteins.

Nuclear Disarmament and the Protection of Cultural Heritage Research paper sysadmin 6 October 2017

States possessing nuclear weapons should be called upon to consider and publish the risks posed to cultural heritage, and their mitigation strategies, in their nuclear-weapons doctrines and policies.

Summary

• Renewed risk assessments for nuclear weapons and policies are taking place around the world in light of nuclear modernization and the changing geostrategic environment that is making the use of nuclear weapons more likely. As such the humanitarian impacts of nuclear weapons and tests have received increased attention. However, the effect on cultural heritage has so far been neglected.
• The potential for armed conflict to destroy cultural heritage has been recognized in international law since 1954. There is significant evidence on the impact of nuclear weapons on cultural heritage including the consequences of their use in Hiroshima and Nagasaki and the effect of nuclear-testing programmes in places of cultural significance since 1945. States that possess nuclear weapons have increased liabilities and responsibilities to protect cultural heritage and cultural rights. The need to protect cultural heritage should strengthen the case for reducing and eliminating nuclear weapons.
• Failure to take into account the protection of heritage in the development of nuclear weapons policies – including disarmament, non-proliferation and arms-control negotiations – significantly undermines states’ existing commitments to protecting heritage threatened by conflict.
• Risk assessments of the impact of nuclear weapons on cultural heritage and important cultural artefacts – and methods of preventing such catastrophic damage – should be part of protecting cultural heritage in every country and the subject of informed public debate. A new body of knowledge on the full range of nuclear weapons impacts would introduce a fresh perspective to inform decision-makers, international organizations and the public in thinking about nuclear weapons policies and practices.
• Risk and resilience frameworks, which provide sets of solutions for risk assessments, would allow assessments of nuclear weapons threats to heritage and highlight vulnerabilities that need to be addressed. Such frameworks would provide a basis for policymakers to identify the world’s cultural heritage most at risk and help develop mitigation strategies to ensure that it is protected. In particular, states possessing nuclear weapons should be called upon to consider and publish the risks posed to cultural heritage, and their mitigation strategies, in their nuclear weapons doctrines and policies, as a contribution to transparency and confidence-building, and as a responsibility to the world’s shared heritage. International organizations, such as the UN Educational, Scientific, and Cultural Organization (UNESCO), have a role to play in bridging security perspectives with protecting cultural heritage.

Cooking in Displacement Settings: Engaging the Private Sector in Non-wood-based Fuel Supply Research paper sysadmin 22 January 2019

In displacement settings, providing cooking solutions that reduce negative impacts on the environment and health remains a challenge for local governments, humanitarian agencies, businesses and refugees.

Summary

• Providing adequate cooking fuel and clean-burning, fuel-efficient stoves in displacement settings has long been a major challenge for local authorities, humanitarian agencies, non-governmental organizations, local communities and refugees themselves. Refugees generally have limited access to modern cooking solutions. Most either depend on insufficient humanitarian agency handouts of ‘in-kind’ firewood or have to travel long distances to collect firewood.
• There is significant potential for private-sector engagement in this context – which, though largely overlooked to date, could result in win-win scenarios for all stakeholders. Refugee camps and other displacement settings present opportunities for private-sector cooking fuel companies to expand their customer bases, with the added advantage for vendors of offering concentrated demand and scope for economies of scale.
• For the Kakuma refugee camp complex in Kenya, the Moving Energy Initiative (MEI) decided to engage with the private sector directly. The MEI requested expressions of interest from local private-sector companies for expanding sales and distribution of fuels in the complex through the concession. The winning company – National Oil Corporation of Kenya – is to receive a prize of $50,000 for its proposed concession to supply liquefied petroleum gas both to refugees in the Kakuma complex and to the surrounding host community.
• The MEI also conducted interviews with various stakeholders in other contexts and countries who are engaged in efforts to develop market-based approaches to providing clean, fuel-efficient cooking solutions to refugees.
• Based on the interviews and the concession process, the MEI recommends greater donor investment and longer-term guaranteed funding for cooking interventions. This is needed to allow sufficient time to build sustainable markets and secure the requisite engagement and investments from the private sector.
• Larger, longer-term investments by the private sector – supported through partnerships with donors and humanitarian agencies – in infrastructure and demand creation (both in and outside the refugee community) can reduce the price of alternative solutions and support a gradual transition away from subsidies.

Infrastructure Management Contracts: Improving Energy Asset Management in Displacement Settings Research paper sysadmin 17 April 2019

This paper highlights a number of options for managing electricity infrastructure in refugee camps and outlines the challenges, opportunities and operational implications associated with them. It takes the Kalobeyei settlement in Kenya as a case study.

• Building and maintaining electricity infrastructure to power offices, businesses, households and other operations in displacement settings is difficult. It is especially challenging for the Office of the United Nations High Commissioner for Refugees (UNHCR) and its partner agencies, because supplying electricity is not their core business.
• Private-sector companies exist that are willing and able to develop infrastructure management contracts to provide energy as a service in displacement settings. However, institutional barriers within humanitarian agencies persist, with short budgeting cycles in particular preventing humanitarian agencies from entering into the sorts of long-term service agreements required by the private sector.
• A number of options exist to leverage the expertise of the private sector through ‘public–private partnership’ (P3) structures. Such mechanisms can promote more efficient management of infrastructure by drawing on private-sector experience and expertise, incentivizing appropriate risk-sharing and providing options to leverage private capital in project development.
• Field work from the Kalobeyei settlement in Kenya suggests that a solar/diesel hybrid mini-grid solution was the most economical option to power camp services and infrastructure there. Compared to distributed diesel generation, the annual savings in operating costs were estimated at $49,880, with the additional investment paid back within 3.6 years.
• Humanitarian agencies need to be willing to change their policies to enable long-term service agreements. Alternatively (or, more likely, in conjunction with this option), financial mechanisms such as partial risk guarantees need to be developed to offset some of the risks. This change will need high-level support from donors and humanitarian agencies.
• Once the first infrastructure management contracts can be signed and tested in displacement locations (through the use of donor funding or otherwise) and associated data collected, it will ease the way for future investments in these types of projects.

Tectonic Politics: Global Political Risk in an Age of Transformation Book sysadmin 7 May 2019

Political risk now affects more markets and countries than ever before and that risk will continue to rise. But traditional methods of managing political risk are no longer legitimate or effective.

In Tectonic Politics, Nigel Gould-Davies explores the complex, shifting landscape of political risk and how to navigate it. He analyses trends in each form of political risk: the power to destroy, seize, regulate, and tax.

He shows how each of these forms reflects a deeper transformation of the global political economy that is reordering the relationship between power, wealth, and values. In a world where everything is political, the craft of engagement is as important as the science of production and the art of the deal.

The successful company must integrate that craft—the engager’s way of seeing and doing—into strategy and culture.

Drawing on a career in academia, business, and diplomacy, Gould-Davies provides corporate leaders, scholars, and engaged citizens with a groundbreaking study of the fastest-rising political risk today. ‘As tectonic plates shape the earth,’ he writes, ‘so tectonic politics forges its governance.’

The book is published as part of the Insights series.

Subsidies and Sustainable Agriculture: Mapping the Policy Landscape Research paper sysadmin 10 December 2019

Agricultural subsidies shape production and consumption patterns, with potentially significant effects on poverty, nutrition and other sustainability concerns. This paper maps the different types of support provided by governments to the agricultural sector, and highlights some of the complex political economy dynamics that underpin the relevant policies.

Summary

• Agricultural subsidies, a mainstay of government policy, have a large part in shaping production and consumption patterns, with potentially significant effects as regards poverty, food security, nutrition, and other sustainability concerns such as climate change, land use practices and biodiversity.
• There are multiple types of direct and indirect support provided by governments to various actors in the agricultural sector; and in terms of political economy, there are complex dynamics underpinning the policies that sustain these subsidies.
• Overall, subsidies targeting producers have the most significant effect on production, and the greater trade-distorting effect. These subsidies promote domestic production and discourage imports, leading to overproduction that is largely disposed of on the international market, with the help of export subsidies. This can tend to intensify negative environmental agricultural practices, such as cultivating marginal land, unsustainable types of intensification, or incentivizing excessive pesticide and fertilizer use.
• On the other hand, producer subsidies that are not tied to output of a specific commodity (i.e. delinked) have far fewer distorting impacts and could help to deliver sustainable outcomes. For example, this type of subsidies can require crop diversification or be linked to conservation of permanent grassland.
• Subsidies that enable transfers to consumers, for example through food stamp programmes, also serve to delink production from consumption, can foster healthier diets, can play an important role in delivering food accessibility and security among low-income groups, and can represent one of the less trade-distorting subsidies.
• If subsidies are to be reformed to help promote healthier diets and encourage more sustainable production, it is essential to understand not only the type and amount of support that key countries provide, but also the domestic dynamics that can shape such policies.
• While price support, input subsidies or investment aids remain the central pillars of programmes in large developing countries such as Brazil, China or India, other economies – notably including the EU and Japan – focus on direct payments, support for general services and set-aside schemes, as well as significant border protection. The US, for its part, has tended to focus on subsidized insurance schemes and food programmes for poorer consumers.
• If subsidies are to deliver policy objectives, their design and implementation should delink production from consumption. For example, consumer subsidies designed to deliver nutrition and food security, or payments for environmental services to enable more environmentally friendly production systems, could prove to be the most effective, least trade-distorting means of achieving more sustainable and equitable agricultural production.
• The political economy of food means that the removal of subsidies is often highly sensitive, and tends to be met with significant resistance. However, reform that delinks support from production through a gradual transition process could ultimately prove successful in delivering effective subsidy schemes.
• Effective subsidy schemes must by design be truly result- and performance-based, supported by robust and objective indicators. At the same time, engaging multiple actors along key commodity value chains – including leading importing and exporting countries, traders and transporters – could lead to the development of international, commodity-specific arrangements that are able to deliver effective nutrition and sustainability goals.

Diagnosing social behavioural dynamics of corruption Other resource dora.popova 8 December 2021

This interactive toolkit identifies the types of social expectations which sustain selected corrupt practices and provides behaviourally-informed recommendations for changing them.

When tackling a problem as complex as corruption, it is important to understand why and how people behave in different situations where corruption occurs. In contexts where it is easier to engage in corruption than avoid it, identifying the social expectations and informal rules which sustain corrupt practices can advance corruption prevention and deepen collective action.  

Behavioural approaches to corruption offer a better understanding of diverse social settings, group dynamics, power distribution, social motivations, and expectations that contribute to a more tolerant environment for certain forms of the phenomenon. They are also highly complementary to traditional corruption measures, which tend to focus on the enforcement of legal sanctions and deterrents. Behavioural approaches, especially those inspired by social norms theory, highlight complex social characteristics and informal rules of specific corrupt practices, and effectively support implementation of more dynamic context-specific anti-corruption interventions.

Since 2016, the Chatham House Africa programme’s Social Norms and Accountable Governance (SNAG) project has adopted a behavioural approach based on social norms methodology to investigate the social beliefs which motivate different forms of corruption. Drawing on the project’s extensive evidence-gathering and analysis, this toolkit offers users navigable behavioural mapping of contextual factors, beliefs, and expectations surrounding common corrupt practices. 

It aims to support anti-corruption actors in diagnosing informal rules and social expectations which sustain corruption in some societies. It also proposes behavioural-informed guidance for developing or adapting anti-corruption interventions and activities, so they account for informal rules of behaviour such as social norms. 
 
The toolkit supports users to:

• Identify whether and how widespread corrupt practices are motivated by social beliefs and expectations.

• Understand how society influences the types of corrupt activity individuals engage in, or avoid, and the factors informing these choices

• Integrate empirical evidence and behavioural insights into anti-corruption strategies from diagnostics to design, and eventual implementation and evaluation

The toolkit presents evidence from SNAG’s research into three key corrupt practices – bribery, embezzlement, and electoral fraud. Each was examined in the context of typical situations in which they occur, such as law enforcement, healthcare, the power sector, voting, and education while critical factors such as religion, gender, and ethnicity were considered. 

The toolkit presents an overview of specific contexts and behavioural features of the practices and provides behavioural-informed recommendations. It also contains pop-up features with definitions and explanations of key concepts. The toolkit is designed to be expandable, allowing further content and behavioural dynamics to be added.   

In nucleotide excision repair, bulky DNA lesions such as UV-induced cyclobutane pyrimidine dimers are removed from the genome by concerted dual incisions bracketing the lesion, followed by gap filling and ligation. So far, two dual-incision patterns have been discovered: the prokaryotic type, which removes the damage in 11–13-nucleotide-long oligomers, and the eukaryotic type, which removes the damage in 24–32-nucleotide-long oligomers. However, a recent study reported that the UvrC protein of Mycobacterium tuberculosis removes damage in a manner analogous to yeast and humans in a 25-mer oligonucleotide arising from incisions at 15 nt from the 3´ end and 9 nt from the 5´ end flanking the damage. To test this model, we used the in vivo excision assay and the excision repair sequencing genome-wide repair mapping method developed in our laboratory to determine the repair pattern and genome-wide repair map of Mycobacterium smegmatis. We find that M. smegmatis, which possesses homologs of the Escherichia coli uvrA, uvrB, and uvrC genes, removes cyclobutane pyrimidine dimers from the genome in a manner identical to the prokaryotic pattern by incising 7 nt 5´ and 3 or 4 nt 3´ to the photoproduct, and performs transcription-coupled repair in a manner similar to E. coli.

Timely repair of DNA double-strand breaks (DSBs) is essential to maintaining genomic integrity and preventing illnesses induced by genetic abnormalities. We previously demonstrated that the E3 ubiquitin ligase SMURF2 plays a critical tumor suppressing role via its interaction with RNF20 (ring finger protein 20) in shaping chromatin landscape and preserving genomic stability. However, the mechanism that mobilizes SMURF2 in response to DNA damage remains unclear. Using biochemical approaches and MS analysis, we show that upon the onset of the DNA-damage response, SMURF2 becomes phosphorylated at Ser384 by ataxia telangiectasia mutated (ATM) serine/threonine kinase, and this phosphorylation is required for its interaction with RNF20. We demonstrate that a SMURF2 mutant with an S384A substitution has reduced capacity to ubiquitinate RNF20 while promoting Smad3 ubiquitination unabatedly. More importantly, mouse embryonic fibroblasts expressing the SMURF2 S384A mutant show a weakened ability to sustain the DSB response compared with those expressing WT SMURF2 following etoposide treatment. These data indicate that SMURF2-mediated RNF20 ubiquitination and degradation controlled by ataxia telangiectasia mutated–induced phosphorylation at Ser384 constitutes a negative feedback loop that regulates DSB repair.

The Phillies continued to bolster their infield depth on Friday by signing versatile veteran Sean Rodriguez to a Minor League contract with an invite to big league Spring Training, MLB.com has learned.

Spring Training is officially here for the Angels, with pitchers and catchers reporting to Tempe Diablo Stadium on Tuesday. And there's a new face at manager, with Brad Ausmus replacing longtime skipper Mike Scioscia this offseason.

The Angels announced their Minor League coaching staffs on Saturday, including former Major League catcher Lou Marson being named the new manager of Triple-A Salt Lake and former big leaguer David Newhan as the new skipper at Double-A Birmingham.

Rebuilding Zimbabwe's Economy: Emmerson Mnangagwa’s Immediate Priorities Expert comment sysadmin 13 December 2017

Zimbabwe cannot expect to rebuild in the same economic model that brought previous prosperity.

Returning to Harare as Zimbabwe’s president-designate Emmerson Mnangagwa declared, ‘We want to grow our economy, we want peace, we want jobs, jobs, jobs.’

Robert Mugabe leaves a legacy of an independent Zimbabwe in a deep economic crisis. Much remains uncertain as to what a new government in Zimbabwe will look like, and there is sure to be continuity as well as considerable change.

What is clear is that a new administration under Mnangagwa will need to turn the economy around to garner support and legitimacy from the Zimbabwean people. Zimbabwe’s economic output halved over the period 1997–2008, and it has not recovered. With more than 80 per cent of Zimbabweans in the informal economy, and with social and economic resilience undermined by previous crises and decades of mismanagement, the stakes for the new leader are very high.

Reform will be difficult particularly because politically connected elites have acquired businesses through uncompetitive means. They will be reluctant to see significantly more competition. But they will also want an improved economic environment. And there is scope for the people of Zimbabwe to benefit from this.

An important change will be in the prioritization of economic stability. Mugabe demonstrated that he was willing to make political decisions irrespective of the economic consequences. Mnangagwa is thought to be less ideological and more of a pragmatist. For him, delivering economic recovery will be crucial to building political support.

The most pressing fiscal priority is the public wage bill. Employment costs account for over 80 per cent of government expenditure, crowding out spending on social programmes, health and education. But the fragility of the economy means that reform cannot be fast-tracked. The public wage bill accounts for over 20 per cent of GDP and is an essential driver of demand. Public sector workers are also politically influential. Another further priority is the reform of state-owned enterprises that are pressuring the fiscus.

A new administration will need to rebuild confidence. Policymakers have been operating in a low-confidence environment for a long time, but for any meaningful change to take root there has to be trust between the government, businesses and the people of Zimbabwe. Businesses and citizens will want to see a plan of action for remonetizing the economy. Zimbabwe faces an acute liquidity crisis. A shortage of US dollars and a lack of confidence in government-issued bond notes are testing resilience.

The financial system has recovered from a crisis of nonperforming loans – triggered by high debt amassed during the post-dollarization boom, and weak corporate governance. But the system remains highly fragile and swamped with government debt. Hard cash US dollar deposits fell from 49 per cent ($582 million) in 2009 to just six per cent ($269 million) in 2016. In 2015, industrial utilization stood at just 34.3 per cent of installed capacity, and it was estimated that just five per cent of the country’s businesses were viable.

The crux of the Zimbabwean economy is the linkage between agriculture and manufacturing. Commercial agriculture contributes approximately 12 per cent of the country’s GDP, and more than 60 per cent of inputs into the manufacturing sector. Tobacco in particular is a vital earner of much needed foreign exchange. Policies to support mid-scale farmers will have multiplier effects. They drive agricultural growth and generate jobs throughout the supply chain.

Zimbabwe also has world-class natural resource endowments including ferrochrome, gold, copper, iron ore, lithium, diamonds and platinum group metals. But longer investment-gestation periods and industry risk adversity will mean that payoffs from fresh investments in this sector will take longer to materialize.

Domestic finance will need to be mobilized to generate recovery, and this will need to be supported by international investment. But international investors entering the country must be cognizant of Zimbabwean’s expectations and also historical perceptions – especially around the scepticism of neoliberal economics as a result of failed structural adjustment programmes in the 1990s.

Zimbabweans have high social expectations for international investors. Educated, tech-savvy, internationally connected youth are at the core of the consumer class that investors will be targeting, to both sell products to but also to staff offices in country. But this cohort also has a greater expectation of international companies to adhere to the norms and standards that they abide by at home and not take advantage of weak governance or poor regulation to exploit citizens.

Investors in Zimbabwe must also recognize that behind the controversial Mugabe policies of land reform and indigenization – the empowerment of local citizens through shared ownership – was a popular desire for postcolonial economic transformation. This sentiment remains. Working in partnership with local entities and communicating the economic contribution made to society will be necessary to build a long-term presence in Zimbabwe, and reap the dividend of what many hope to be a new start for the country.

Fresh thinking is required from domestic policymakers and international partners. A skilled population and estimated 3-5 million-strong diaspora will bring international experience and make a considerable contribution to this process. Some of this thinking has been done. The Lima process of re-engagement with international financial institutions that was agreed at the end of 2015 has laid some of the groundwork, especially around international expectations regarding both economic and governance reform – the substance of which was analysed in a 2016 Chatham House paper. The implementation of recommendations of the well-regarded auditor-general’s report on SOE reform will also be a key prerequisite for long-term reform.

Zimbabweans are not alone in processing what has happened and how to react. Investors have long been poised to capitalize on what is perceived to be one of the continent’s best long-term prospects. A lot will remain unchanged following the transition. But significantly, for the first time in decades, there is a real opportunity to effect positive change and improve the livelihoods of millions of Zimbabweans.

Improving Economic Management for Sustainable Growth in Zambia 13 July 2018 — 9:00AM TO 10:00AM Anonymous (not verified) 19 June 2018 Chatham House, London

THIS EVENT IS POSTPONED.

High levels of infrastructure investment funded by commercial loans, against a backdrop of subdued economic growth, resulted in an increase in Zambia’s public external debt from $8.7 billion in 2017 to $9.3 billion in March 2018.

In June 2018 Zambia’s Ministry of Finance announced new austerity measures aimed at reducing the country’s debt burden, as part of an ongoing reform agenda that is hoped to stabilise the economy.

In the meantime Zambia grapples with severe social and development challenges. Decreased spending in health, education and social protection, and poor access in rural areas, have already left Zambia ranked 139th out of 188 countries in the UNDP’s 2016 human development index.

At this meeting Margaret Mwanakatwe, minister of finance, discusses the government’s financial reform agenda, its engagement with creditors and IFIs, and plans for generating sustainable growth and job creation.

Zimbabwe Futures 2030: Policy Priorities for Industrialization, Agri-Business and Tourism 6 June 2019 — 9:30AM TO 1:15PM Anonymous (not verified) 21 June 2019 Bulawayo, Zimbabwe

Economic Recovery and Anticorruption in South Africa: Assessing Progress on the Reform Agenda 4 December 2019 — 3:00PM TO 4:00PM Anonymous (not verified) 25 November 2019 Chatham House | 10 St James's Square | London | SW1Y 4LE

South Africa has significant economic potential based on its resource endowment, quality human capital and well-developed infrastructure compared to the region. However, the country’s economic growth rate has not topped 2 per cent since 2013, and in 2018, was below 1 per cent. This has put a strain on citizens and communities in a country that still suffers from structural inequality, poverty and high unemployment. Economic recovery and anti-corruption were the central pillars of President Cyril Ramaphosa’s 2019 electoral campaign and he has set an investment target of $100 billion. However, voters and investors alike are demanding faster and more visible progress from the country’s enigmatic leader who has a reputation for caution and calculation.

At this event, Professor Nick Binedell will discuss the progress of and opposition to the president’s economic reform agenda and the opportunities for international investment to support long term inclusive and sustainable growth in South Africa.

Attendance at this event is by invitation only.

Mozambique’s Peace and National Reconciliation Agreement: One Year On 6 August 2020 — 2:30PM TO 4:30PM Anonymous (not verified) 29 July 2020 Online

August 6, 2020 marks one year since the Peace and National Reconciliation Agreement was signed in Maputo. The agreement, signed by the President of Mozambique Filipe Nyusi and RENAMO leader Ossufo Momade, and witnessed by regional and international political and religious leaders, ended the return to conflict that started in 2013.

It also paved the way for Mozambique’s national elections in October 2019. Since the agreement, the Mozambique Liberation Front (FRELIMO) won a landslide victory in the elections, weakening RENAMO, and a splinter group has conducted targeted armed violence in Manica and Sofala provinces. Yet, the disarmament, demobilization, and reintegration (DDR) process has made progress.

At this event, senior figures reflect on the peace agreement and the key factors of its success. The event also draws upon insights from the authors of recent publications on the latest peace agreement in the context of longer term trends of democratization and peace-building in Mozambique.

A Chatham House Africa Programme research paper published in August 2019, Prospects for a Sustainable Elite Bargain in Mozambique: Third Time Lucky?, examined how the deal was achieved. The Portuguese version includes the full text of the peace accord. Read the research paper in Portuguese or English here.

Inclusion, agency and influence: The role of women in Zimbabwe’s economy 8 July 2021 — 3:00PM TO 4:30PM Anonymous (not verified) 2 July 2021 Online

Speakers discuss the changing role of women in Zimbabwe’s economic structures and the priorities for promoting greater economic inclusion, agency and influence of women.

Zimbabwe’s National Development Strategy of 2021-2025 highlights the importance of gender sensitivity in policymaking and of women’s economic participation in attaining the government’s Vision 2030.

However, women have been among the worst affected groups by the devastating effects that COVID-19 has had on Zimbabwe’s already floundering economy, which has exacerbated the challenges they face in economic life, such as access to credit, financial services and social security.

Leveraging existing structures such as women’s groups, micro-finance facilities, education and training, and national gender mechanisms, as well as supporting wider financial and digital inclusion in Zimbabwe, is central for the country’s sustained economic recovery.

This event also focuses on the differing impacts of COVID-19 on women’s economic activities across various sectors, as well as along rural-urban and formal-informal economy lines.
