Finally, disruption of three genes significantly attenuated fungal virulence, but their mutations had different influences. CONCLUSIONS In addition to their consistent roles in mitochondrial division and mitophagy, three fission-related genes perform divergent roles in the development and virulence of the entomopathogenic fungus B. bassiana. SIGNIFICANCE AND IMPACT OF THE STUDY This study shows that mitochondrial fission is associated with lifecycle of B. bassiana. These findings provide information for the manipulation of fungal physiology and facilitate the application of entomopathogenic fungi. © 2020 The Society for Applied Microbiology.Theory on the evolution of niche width argues that resource heterogeneity selects for niche breadth. For parasites, this theory predicts that parasite populations will evolve, or maintain, broader host ranges when selected in genetically diverse host populations relative to homogeneous host populations. To test this prediction, we selected the bacterial parasite Serratia marcescens to kill Caenorhabditis elegans in populations that were genetically heterogeneous (50% mix of two experimental genotypes) or homogeneous (100% of either genotype). After 20 rounds of selection, we compared the host range of selected parasites by measuring parasite fitness (i.e. virulence, the selected fitness trait) on the two focal host genotypes and on a novel host genotype. As predicted, heterogeneous host populations selected for parasites with a broader host range these parasite populations gained or maintained virulence on all host genotypes. This result contrasted with selection in homogeneous populations of one host genotype. Here, host range contracted, with parasite populations gaining virulence on the focal host genotype and losing virulence on the novel host genotype. This pattern was not, however, repeated with selection in homogeneous populations of the second host genotype these parasite populations did not gain virulence on the focal host genotype, nor did they lose virulence on the novel host genotype. Our results indicate that host heterogeneity can maintain broader host ranges in parasite populations. Individual host genotypes, however, vary in the degree to which they select for specialization in parasite populations. © 2020 European Society For Evolutionary Biology.

METHODS OF STUDY The study was designed as a prospective cohort study. Forty-five women with two or more RPL of unknown etiology and twenty fertile women who had at least one or more live-born infants were enrolled prospectively from Jan 2017 to Jul 2019. RESULTS The proportions of PD-1+ Th1 (CD4+ /IFN-γ+ /CD279+ and CD4+ /TNF-α+ /CD279+ ) and PD-1+ Th17 cells (CD4+ /IL17+ /CD279+ ) were significantly lower in RPL group than those of controls ( p 0.05, respectively). In Th1, Th17 and Treg cells, the proportions of PD-L1+ (CD274+ ) cells were significantly higher than those of PD-1+ (CD279+ ) cells in both RPL group and controls ( p less then 0.05, respectively). CONCLUSION PD-1 and PD-L1 expressions on Th17 cells as well as PD-1 expression on Th1 cells were significantly down-regulated in women with RPL, which may lead to increased Th1 and Th17 immunity, and imbalance between Th17, Th1 and Treg cells in women with RPL.

To investigate the role of lncRNA PRRT3-AS1 in the regulation of PPARγ gene-mediated mTOR signaling pathway in proliferation, apoptosis and autophagy of PC cells. What is the main finding and its importance? This study verified the targeting relation between lncRNA PRRT3-AS1 and PPARγ, and demonstrated that silencing of lncRNA PRRT3-AS1 can upregulate apoptosis and autophagy yet downregulate proliferation, migration and invasion of PC cells through the mTOR signaling pathway. Greater efforts are still necessitated to consolidate the therapeutic values of lncRNA PRRT3-AS1 in clinical trials and treatment of PC in the future. ABSTRACT Although long noncoding RNAs (lncRNAs) are correlated with multiple cancers, their molecular mechanisms in prostate cancer (PC) remain inadequately understood. This study investigated the effects of lncRNA PRRT3-AS1 on the progression of prostate cancer (PC) with involvement of peroxisome proliferator-activated receptor gamm in the regression of xenografts in nude mice. Based on the in vitro and in vivo experiments, silencing of lncRNA PRRT3-AS1 was observed to activate the PPARγ gene, which in turn could inhibit PC cell proliferation and promote apoptosis and autophagy by blocking the mTOR signaling pathway.

Interdigitating secondary foot processes form a highly selective filter for proteins in the kidney, the slit membrane. Knockdown of slit membrane components such as Nephrin or Neph1 and cytoskeletal adaptor proteins such as CD2AP in mice leads to breakdown of the filtration barrier with foot process effacement, proteinuria, and early death of the mice. Less is known about the crosstalk between the slit membrane-associated proteins and cytoskeletal components inside the podocyte foot processes. Our study shows that LASP-1, an actin-binding protein, is highly expressed in podocytes. Electron microscopy studies demonstrate that LASP-1 is found at the slit membrane suggesting a role in anchoring slit membrane components to the actin cytoskeleton. Live cell imaging experiments with transfected podocytes reveal that LASP-1 is either part of a highly dynamic granular complex or a static, actin cytoskeleton-bound protein. We identify CD2AP as a novel LASP-1 binding partner that regulates its association with the actin cytoskeleton. Activation of the renin-angiotensin-aldosterone system, which is crucial for podocyte function, leads to phosphorylation and altered localization of LASP-1. In vivo studies using the Drosophila nephrocyte model indicate that Lasp is necessary for the slit membrane integrity and functional filtration. © 2020 The Authors.
