CircRNA serves a crucial role in the development of heart failure (HF). Nevertheless, the regulatory mechanisms of circ_0062389 in HF are unknown. This study aims to examine the effect and mechanism of circ_0062389 on cardiomyocyte apoptosis in HF rats and H9C2 cells. Rats were divided into 5 groups (n = 8/group) the Control group, Sham group, HF group, HF + si-NC group, and HF + si-circRNA group. The echocardiography was used to examine the cardiac function, including LVIDd, LVIDs, IVSd, and IVSs. The apoptosis of myocardial tissue was detected through TUNEL method. H9C2 cells were randomly assigned into Control group (untransfected H9C2 cells), H/R group (untransfected H/R H9C2 cells), H/R + si-NC group (transfected si-NC) and H/R + si-circRNA group (transfect si-circ_0062389). Cell apoptosis was assessed through flow cytometry. The expression of circ_0062389 in myocardial tissues of HF rats was significantly higher than that of Control group and Sham group. Silencing circ_0062389 significantly reduced the levels of LVIDd, LVIDs, IVSd, and IVSs. Additionally, silencing circ_0062389 could significantly reduce the apoptosis rate of rat cardiomyocytes. Besides, silencing circ_0062389 significantly reduced the expression of TGF-β1 and Smad3 protein. Silencing circ_0062389 could alleviate cardiomyocyte apoptosis in HF rats via modulating TGF-β1/Smad3 signaling pathway, which might be a promising target for the treatment of HF.Ischemic stroke is a common clinical cardiovascular disease and often accompanied by central nervous system injury. It often causes paralysis or loss of motor function after central nervous system injury and significantly reduces the patient's quality of life. find more At present, there is no effective treatment strategy for nerve damage caused by ischemic stroke. Therefore, it is urgently need to explore effective treatment targets. The protein expression of SOX5, VEGF and apoptosis related proteins were measured by western blot. The mRNA expression of SOX5 and VEGF were detected by RT-qPCR. The concentration of S100B and GFAP which are related to nerve damage were detected using ELISA assay. The transcriptional regulation of SOX5 on VEGF was detected using ChIP-PCR and dual luciferase reporter gene assays. The cell apoptosis was measured by TUNEL assay and cell viability was detected by CCK-8 assay. In our study, we found that the expression of SOX5 was significantly reduced when LPS induced apoptosis in PC-12 cells. Overexpression of SOX5 repaired LPS-induced apoptosis. SOX5 promotes VEGF expression as a transcription factor to activate the PI3K/AKT pathway. VEGF also repairs nerve injury and brain tissue injury caused by ischemic stroke. In conclusion, SOX5 transcription regulates the expression of VEGF to activate the PI3K/AKT pathway, which repaired nerve damage caused by ischemic stroke. Therefore, SOX5 could be a new targetto regulate VEGF which can repair nerve injury induced by ischemic stroke.Glycolytic potential (GP) calculated based on glucose, glycogen, glucose-6-phosphate, and lactate contents is a critical factor for multiple meat quality characteristics. However, the genetic basis of glycolytic metabolism is still unclear. In this study, we constructed six RNA-Seq libraries using longissimus dorsi (LD) muscles from pigs divergent for GP phenotypic values and generated the whole genome-wide gene expression profiles. Furthermore, we identified 25,880 known and 220 novel genes from these skeletal muscle libraries, and 222 differentially expressed genes (DEGs) between the higher and lower GP groups. Notably, we found that the Lactate dehydrogenase B (LDHB) and Fructose-2, 6-biphosphatase 3 (PFKFB3) expression levels were higher in the higher GP group than the lower GP group, and positively correlated with GP and lactic acid (LA), and reversely correlated with pH value at 45 min postmortem (pH45min). Besides, LDHB and PFKFB3 expression were positively correlated with drip loss measured at 48 h postmortem (DL48h) and drip loss measured at 24 h postmortem (DL24h). Collectively, we identified a serial of DEGs as the potential key candidate genes affecting GP and found that LDHB and PFKFB3 are closely related to GP and GP-related traits. Our results lay a solid basis for in-depth studies of the regulatory mechanisms on GP and GP-related traits in pigs.Plant Glycogen Synthase Kinase 3 (GSK3)/SHAGGY-like kinase (GSK) proteins play important roles in modulating growth, development, and stress responses in several plant species. However, little is known about the members of the potato GSK (StGSK) family. Here, nine StGSK genes were identified and phylogenetically grouped into four clades. Gene duplication analysis revealed that segmental duplication contributed to the expansion of the StGSK family. Gene structure and motif pattern analyses indicated that similar exon/intron and motif organizations were found in StGSKs from the same clade. Conserved motif and kinase activity analyses indicated that the StGSKs encode active protein kinases, and they were shown to be distributed throughout whole cells. Cis-acting regulatory element analysis revealed the presence of many growth-, hormone-, and stress-responsive elements within the promoter regions of the StGSKs, which is consistent with their expression in different organs, and their altered expression in response to hormone and stress treatments. Association network analysis indicated that various proteins, including two confirmed BES1 family transcription factors, potentially interact with StGSKs. Overexpression of StSK21 provides enhanced sensitivity to salt stress in Arabidopsis thaliana plants. Overall, these results reveal that StGSK proteins are active protein kinases with purported functions in regulating growth, development, and stress responses.There are a few studies indicating that small molecular compounds affect the proliferation, differentiation, apoptosis, and autophagy of female germline stem cells (FGSCs). However, whether small molecular compound 28 (C28) affect development of FGSCs remains unknown. In this study, we found that C28 reduced the viability and proliferation of FGSCs, respectively. Additionally, western blotting showed that the expression of autophagy marker light chain 3 beta II (LC3B-II) was significantly increased and expression of sequestosome-1 (SQSTM1) was significantly reduced in C28-treated groups. Immunofluorescence showed that, in C28-treated groups, the number of LC3B-II-positive puncta was increased significantly. These results indicated that C28 induced autophagy of FGSCs in vitro. Furthermore, data from Chromatin Immunoprecipitation Sequencing for H3K27ac showed that autophagy-related biological processes such as regulation of mitochondrial membrane potential, Golgi vesicle transport, and cellular response to reactive oxygen species were different after C28-treated.
