This study aimed to explore the protective effect of exosomal miR-30a-5p on podocyte pyroptosis in DN. Methods: Streptozotocin was used to establish the mouse model of DN. Human bone marrow MSC-derived exosomes were extracted and identi fi ed via transmission electron microscopy, nanoparticle tracking analysis, and western blotting. MiR-30a-5p mimics and non-control (NC) mimics were transfected into MSCs and podocytes, and exosomes were isolated from the MSCs. High glucose (HG)-induced podocyte model was established to determine the effect of exosomal miR-30a-5p on pyroptosis and in fl ammation in vitro . Results: MiR-30a-5p was expressed at low levels in DN models, while NLR family pyrin domain containing 3 (NLRP3), caspase-1, gasdermin-N (GSDMD-N), and pro-in fl ammatory factors (tumor necrosis factor-alpha, interleukin (IL)-1beta, and IL-18) were augmented. In vitro , miR-30a-5p expression in the HG-damaged podocytes was down-regulated, while NLRP3 was up-regulated. Interestingly, miR-30a-5p overexpression diminished HG-induced podocyte injury, as proven by increased activity and decreased pyroptosis of podocytes. Concurrently, the up-regulation of miR-30a-5p could inhibit the expression of pro-in fl ammatory factors, caspase-1, GSDMD-N, and NLRP3 in HG-induced podocytes. MSC-derived exosomal miR-30a-5p treatment of HG-damaged cells has similar effects to miR-30a-5p mimics treatment. Overexpression of NLRP3 reversed the effect of miR-30a-5p mimics on HG-induced podocytes. Conclusion: This research con fi rmed that exosomal miR-30a-5p regulates pyroptosis via mediating NLRP3 in DN.","PeriodicalId":55384,"journal":{"name":"Biocell","volume":"36 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73838290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A safe and effective nano-drug system of functionalized selenium-containing nanoparticles (SeNPs) was developed with lentinan (LNT) (SeNPs@LNT). Mice spermatocyte line GC2-spg cells were treated with SeNPs@LNT (1, 2, 4, 8, 16, 32 μM) for 24–72 h to evaluate the cytotoxicity of selenium. GC2-spg cells were randomly divided into the following groups: control, hydrogen peroxide (H2O2), SeNPs@LNT, and H2O2+SeNPs@LNT groups. H2O2+SeNPs@LNT group was pretreated with SeNPs@LNT 4 μM for 12 h, followed by H2O2 600 μM for 8 h. The cell viability decreased in the H2O2 group and increased significantly in the SeNPs@LNT group. Compared with the H2O2 group, the SeNPs@LNT+H2O2 group exhibited obvious red fluorescence, indicating a higher level of mitochondrial membrane potential. The content of intracellular reactive oxygen species (ROS) in the SeNPs@LNT group reduced significantly, and the intensity of green fluorescence in the SeNPs@LNT+H2O2 group decreased significantly compared with the H2O2 group, indicating the inhibitory effect of SeNPs@LNT on the generation of ROS-induced oxidative stress. The activity of GPx and SOD increased significantly in the SeNPs@LNT group. The expression of p53 decreased significantly under the intervention of nano-selenium, and GPx1 expression increased. In the oxidative stress group, the expressions of DNA damage-related proteins and apoptosis-related proteins were higher than those in other groups. Thus, SeNPs@LNT can promote GC2-spg cell proliferation, improve GPx and SOD activities, remove intracellular ROS, and reduce mitochondrial damage and functional abnormalities caused by oxidative stress by regulating the ERK and p53 protein levels. SeNPs@LNT has good biological activity and antioxidant effect, which can be used to protect the male reproductive system from","PeriodicalId":55384,"journal":{"name":"Biocell","volume":"333 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77390487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BTLA is associated with a variety of diseases, especially cancer immunity. However, the function of BTLA in various cancers and its clinical prognostic value have still not been comprehensively analyzed. This study aimed to identify the relationship between BTLA and cancer from the perspectives of differences in BTLA expression, its clinical value, immune infiltration, and the correlation with immune-related genes in various cancers. Data regarding mRNA expression, miRNA expression, lncRNA expression, and clinical data of patients of 33 existing cancers were collected from the TCGA database. Target miRNA of BTLA and the lncRNA that interacts with the target miRNA were obtained from the StarBase database. Based on bioinformatics analysis methods, the relationship between various types of cancers and BTLA was thoroughly investigated, and a competing endogenous RNA network of BTLA, target miRNA, and interacting lncRNA was constructed. The Kaplan-Meier (KM) prognostic analysis of BTLA and target miRNA (has-miR-137) in various types of cancers was completed using the KM plotter. BTLA expression varied in different cancers, with statistical significance in nine cancer types. KM plotter to analyze the overall survival (OS) and regression-free survival prognosis of cancer patients revealed that the BTLA expression was statistically different in the OS of 11 types of cancers out of 21 types of cancers; the OS of 8 type of cancers was also statistically different. Correlation analysis of tumor immune genes revealed a positive correlation of BTLA expression with immunosuppressive gene (CTLA4 and PDCD1) expression. Gene Set Enrichment Analysis showed that BTLA and its co-expressed genes mainly act through biological processes and pathways, including immune response regulation, cell surface receptor signaling pathway, antigen binding, antigen receptor-mediated signaling pathway, and leukocyte migration. BTLA has the potential as a prognostic marker for CLL, COAD, NSCLC, and OV and a diagnostic marker for CLL, COAD, and KIRC. BTLA has a close and complex relationship with the occurrence and development of tumors, and cancer immunotherapy for BTLA is worthy of further analysis.","PeriodicalId":55384,"journal":{"name":"Biocell","volume":"246 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76755198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
