rc The FKH domain in FOXP3 mRNA frequently contains mutations in hepatocellular carcinoma that influence the subcellular localization and functions of FOXP3 [Molecular Bases of Disease] By feedproxy.google.com Published On :: 2020-04-17T00:06:05-07:00 The transcription factor forkhead box P3 (FOXP3) is a biomarker for regulatory T cells and can also be expressed in cancer cells, but its function in cancer appears to be divergent. The role of hepatocyte-expressed FOXP3 in hepatocellular carcinoma (HCC) is unknown. Here, we collected tumor samples and clinical information from 115 HCC patients and used five human cancer cell lines. We examined FOXP3 mRNA sequences for mutations, used a luciferase assay to assess promoter activities of FOXP3's target genes, and employed mouse tumor models to confirm in vitro results. We detected mutations in the FKH domain of FOXP3 mRNAs in 33% of the HCC tumor tissues, but in none of the adjacent nontumor tissues. None of the mutations occurred at high frequency, indicating that they occurred randomly. Notably, the mutations were not detected in the corresponding regions of FOXP3 genomic DNA, and many of them resulted in amino acid substitutions in the FKH region, altering FOXP3's subcellular localization. FOXP3 delocalization from the nucleus to the cytoplasm caused loss of transcriptional regulation of its target genes, inactivated its tumor-inhibitory capability, and changed cellular responses to histone deacetylase (HDAC) inhibitors. More complex FKH mutations appeared to be associated with worse prognosis in HCC patients. We conclude that mutations in the FKH domain of FOXP3 mRNA frequently occur in HCC and that these mutations are caused by errors in transcription and are not derived from genomic DNA mutations. Our results suggest that transcriptional mutagenesis of FOXP3 plays a role in HCC. Full Article
rc The streptococcal multidomain fibrillar adhesin CshA has an elongated polymeric architecture [Microbiology] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 The cell surfaces of many bacteria carry filamentous polypeptides termed adhesins that enable binding to both biotic and abiotic surfaces. Surface adherence is facilitated by the exquisite selectivity of the adhesins for their cognate ligands or receptors and is a key step in niche or host colonization and pathogenicity. Streptococcus gordonii is a primary colonizer of the human oral cavity and an opportunistic pathogen, as well as a leading cause of infective endocarditis in humans. The fibrillar adhesin CshA is an important determinant of S. gordonii adherence, forming peritrichous fibrils on its surface that bind host cells and other microorganisms. CshA possesses a distinctive multidomain architecture comprising an N-terminal target-binding region fused to 17 repeat domains (RDs) that are each ∼100 amino acids long. Here, using structural and biophysical methods, we demonstrate that the intact CshA repeat region (CshA_RD1–17, domains 1–17) forms an extended polymeric monomer in solution. We recombinantly produced a subset of CshA RDs and found that they differ in stability and unfolding behavior. The NMR structure of CshA_RD13 revealed a hitherto unreported all β-fold, flanked by disordered interdomain linkers. These findings, in tandem with complementary hydrodynamic studies of CshA_RD1–17, indicate that this polypeptide possesses a highly unusual dynamic transitory structure characterized by alternating regions of order and disorder. This architecture provides flexibility for the adhesive tip of the CshA fibril to maintain bacterial attachment that withstands shear forces within the human host. It may also help mitigate deleterious folding events between neighboring RDs that share significant structural identity without compromising mechanical stability. Full Article
rc The resource curse has not been lifted By feedproxy.google.com Published On :: Fri, 09 Oct 2015 15:40:02 +0000 5 August 2015 20150804ResourceCurse2.jpg Hoping to make a little money from Sudan's ocean of black gold, a woman sells tea to roughnecks at an oil rig near Bentiu, Sudan. Photo by Getty Images. During a decade-long commodities boom, new or emerging producers of oil, gas or mineral resources registered some of the fastest rates of economic growth in the world. Development banks, governments giving foreign aid, extractives companies and major consultancies broadly agreed that ‘extractives-led growth’ is a viable path to socio-economic development for poor countries. Following over a year of decline in global commodities prices and as efforts to tackle climate change mount, a new paper re-examines the 'curse of natural resources'. It finds that a policy of extractives-led growth entails serious risks. As governments of countries as diverse as Afghanistan, Mauritania, Somalia, Liberia and Cuba prepare to follow an extractives-led growth path, both the advice being handed to them and the growth model itself require a fundamental rethink.The Resource Curse Revisited argues that:The steep decline in the oil price in the second half of 2014 demolished the main assumption of the extractives-led growth agenda. The assumption that prices of raw materials would continue to increase as global demand grew and well-established sources were exhausted has actually led several low- to middle-income producers such as Ghana into unmanageable debt. At the very least, the current price context puts new producers at a serious disadvantage, as the focus on cost-cutting has made investors reluctant to accept the risks of developing projects in countries with little infrastructure or capacity to support them.Good governance initiatives are not the antidote to the resource curse. There has often been a mismatch in terms of policy advice given (for example on transparency and revenue management) and the capacity of a country to implement it. Furthermore, basing economic growth on the extraction of below-ground resources will create strong pressures towards poor governance. In the absence of strong institutions, this path leads to the enrichment of minority elite groups, whose interest in capturing rents is likely to become a barrier to improving governance.Both governments with extractives potential and those advising them give too little consideration to the size and nature of the resource base. If extractives-led growth is to be sustained, resource extraction must persist long enough for new economic sectors to emerge and generate revenues that can support government spending and import needs as income from extractives declines.The extractives-led growth model, in its current form, is at odds with green growth strategies. The advice from international agencies and initiatives to countries with extractive resources offers no suggestions on how governments should manage the risk of stranded assets or how they can reconcile extractives-led growth with national sustainable-development goals.The report concludes that the extractives-led growth agenda has tended to reinforce domestic, government and investor pressures to ‘develop fast’. However, this can threaten long-term opportunities for robust economic diversification. In many cases, there is a strong case for slowing development of extractives projects to allow time to develop the capacity of the government and the private sector to maximize the linkages with the rest of the economy.Avoiding the resource curse needs not only good governance but also an economic policy that provides for the transition of an economy over time in accordance with its competitive advantages. This report recommends that countries considering extractives development, and their would-be advisors, take into account a wider set of issues at the outset including the likely value of the asset to the economy over time, the options for slow or indeed no development of extractives, and how the rest of the economy would lessen reliance on support from the extractives sector over time.
