Then, we identified the potential KIAA1429 regulating gene as c-Jun by mRNAs high-throughput sequencing and RIP assay. By luciferase assay, we verified that KIAA1429 regulated the expression of c-Jun in an m6A-independent manner. Finally, the overexpression of c-Jun rescued the inhibition of proliferation caused by KIAA1429 knockdown in gastric cancer cells. KIAA1429 could act as an oncogene in gastric cancer by stabilizing c-Jun mRNA in an m6A-independent manner. This highlights the functional role for KIAA1429 as a potential prognostic biomarker and therapeutic target in gastric cancer. © 2020 Wiley Periodicals, Inc.Neural stem/progenitor cells (NSPCs) persist in the mammalian subventricular zone throughout life, where they can be activated in response to physiological and pathophysiological stimuli. A recent study indicates metabotropic glutamate receptor 4 (mGluR4) is involved in regulating NSPCs behaviors. Therefore, defining mGluR4 function in NSPCs is necessary for determining novel strategies to enhance the intrinsic potential for brain regeneration after injuries. In this study, mGluR4 was functionally expressed in SVZ-derived NSPCs from male Sprague-Dawley rats, in which the cyclic adenosine monophosphate concentration was reduced after treatment with the mGluR4-specific agonist VU0155041. Additionally, lateral ventricle injection of VU0155041 significantly decreased 5-bromo-2'-deoxyuridine (BrdU)+ and Ki67+ cells, while increased Doublecortin (DCX)/BrdU double-positive cells in SVZ. In cultured NSPCs, mGluR4 activation decreased the ratio of BrdU+ cells, G2/M-phase cells, and inhibited Cyclin D1 expression, whereas it increased neuron-specific class III β-tubulin (Tuj1) expression and the number of Tuj1, DCX, and PSA-NCAM-positive cells. However, pharmacological blocking mGluR4 with the antagonist MSOP or knockdown of mGluR4 abolished the effects of VU0155041 on NSPCs proliferation and neuronal differentiation. Further investigation demonstrated that VU0155041 treatment down-regulated AKT phosphorylation and up-regulated expression of the phosphatase and tensin homolog protein (PTEN) in NSPCs culture. Moreover VU0155041-induced proliferating inhibition and neuronal differentiating amplification in NSPCs were significantly hampered by VO-OHpic, a PTEN inhibitor. We conclude that activation of mGluR4 in SVZ-derived NSPCs suppresses proliferation and enhances their neuronal differentiation, and regulation of PTEN may be involved as a potential intracellular target of mGluR4 signal. © 2020 International Society for Neurochemistry.Environmentally transmitted parasites spend time in the abiotic environment, where they are subjected to a variety of stressors. Learning how they face this challenge is essential if we are to understand how host-parasite interactions may vary across environmental gradients. We used a zooplankton-bacteria host-parasite system where availability of sunlight (solar radiation) influences disease dynamics to look for evidence of parasite local adaptation to sunlight exposure. We also examined how variation in sunlight tolerance among parasite strains impacted host reproduction. Parasite strains collected from clearer lakes (with greater sunlight penetration) were most tolerant of the negative impacts of sunlight exposure, suggesting local adaptation to sunlight conditions. This adaptation came with both a cost and a benefit for parasites parasite strains from clearer lakes produced relatively fewer transmission stages (spores) but these strains were more infective. After experimental sunlight exposure, the most sunlight-tolerant parasite strains reduced host fecundity just as much as spores that were never exposed to sunlight. Sunlight availability varies greatly among lakes around the world. Our results suggest that the selective pressure sunlight exposure exerts on parasites may impact both parasite and host fitness, potentially driving variation in disease epidemics and host population dynamics across sunlight availability gradients. © 2020 The Authors.

The gel structure and properties were studied with or without Ultraviolet A (UVA) irradiation. Electron spin resonance results showed that riboflavin produced ·OH under UVA irradiation, which subsequently oxidized the MP. https://www.selleckchem.com/products/tegatrabetan.html Compared with the control group, the addition of riboflavin with UVA irradiation increased the strength of the MP gel. The rheological results showed that under UVA irradiation, addition of riboflavin facilitated the sol-gel transition between 45 and 52°C, indicating that oxidation led to significant structural changes which in turn resulted in a more compact and uniform gel network. The presence of riboflavin led to increased carbonyl content and decreased sulfhydryl and free amino groups, which decreased the protein solubility and promoted alpha-helical conformational loss in the secondary structure of the MP. These results all indicated that the MP has been oxidized. Electrophoresis revealed that myosin heavy chains were aggregated in the UVA-treated riboflavin-added MP gel, indicating that protein cross-linking has been induced. All the results indicated that the ·OH produced by riboflavin under UVA irradiation oxidized the MP, and improved protein crosslinking and gel properties. © 2020 Wiley Periodicals, Inc.PREMISE Plant flowering time plays an important role in plant fitness and thus evolutionary processes. Soil microbial communities are diverse and have a large impact, both positive and negative, on the host plant. However, owing to few available studies, how the soil microbial community may influence the evolutionary response of plant populations is not well understood. Here we sought to uncover whether belowground microbial communities act as an agent of selection on flowering and growth traits in the common morning glory, Ipomoea purpurea. METHODS We performed a controlled greenhouse experiment in which genetic lines of I. purpurea were planted into either sterilized soils or in soils that were sterilized and inoculated with the microbial community from original field soil. We could thus directly test the influence of alterations to the microbial community on plant growth, flowering, and fitness and assess patterns of selection in both soil microbial environments. RESULTS A more complex soil microbial community resulted in larger plants that produced more flowers.
