In this study, we found that BRG1 improved the efficiency of porcine iPSC generation, and upregulated the expression of pluripotency-related factors. Further analysis revealed that BRG1 promoted cellular glycolysis, and increased levels of glycolysis-related metabolites. It enhanced the transcriptional activity of glycolysis-related gene HK2, PKM2, and PFK-1 promoters, and decreased the enrichment of H3K9me3 in glycolysis- and pluripotency-related gene promoters. BRG1 also increased the phosphorylation level at the Ser473 site of AKT protein. The specific PI3K/AKT signaling pathway inhibitor, LY294002, impaired the generation of porcine iPSCs, downregulated the expression of pluripotency-related factors, and inhibited cellular glycolysis, overexpressing BRG1 rescued those changes caused by LY294002 treatment. In addition, the glycolysis inhibitor 2-DG and BRG1 inhibitor PFI-3 had similar effects to LY294002.

MTSS1 has attracted much attention for its role as a tumor suppressor, being absent or expressed at reduced levels in advanced and metastasizing cancers. Occasionally, MTSS1 is, instead, upregulated in metastasis and, in some cases, even in primary tumors. In addition to these well-established functions of MTSS1 linked to its I-BAR- and WH2-domains, the protein is involved in modulating cell-cell contacts, cell differentiation, lipid metabolism, and vesicle formation and acts as a scaffolding protein for several E3 ubiquitin ligases. MTSS1 is classified as a housekeeping protein and is never mutated despite the several pathologic phenotypes linked to its dysregulation. Despite MTSS1's involvement in fundamental signaling pathways, MTSS1 gene ablation is not ubiquitously lethal, although it affects embryonic development. Due to MTSS1´s involvement in many seemingly disparate processes, with many cases lacking mechanistic explanations, we found it timely to review the recent data on MTSS1's role at the cellular level, as well as in health and disease, to direct further studies on this interesting multifunctional protein.</p>","PeriodicalId":10007,"journal":{"name":"Cellular and Molecular Life Sciences","volume":"81 1","pages":"472"},"PeriodicalIF":6.2,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11615175/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142766629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
