To understand the role of the catalytic α2 subunit of AMPK in skeletal muscle energy metabolism, myotube cultures were established from AMPKα2+/+ and AMPKα2-/- mice. Myotubes from AMPKα2-/- mice had lower basal oleic acid and glucose oxidation compared to myotubes from AMPKα2+/+ mice. However, the relative response to mitochondrial uncoupling was increased for oleic acid oxidation. Incorporation of acetate into lipids was also lower in myotubes from AMPKα2-/- mice. Proteomics analysis revealed that AMPKα2-/- myotubes had upregulated pathways related to mitochondrial function and fatty acid oxidation, and decreased pathways related to fatty acid biosynthesis. In conclusion, ablation of AMPKα2 catalytic subunit in skeletal muscle cells resulted in reduced basal oxidation of glucose and fatty acids, however upregulated pathways related to mitochondrial function and fatty acid oxidation and reduced lipid formation.","PeriodicalId":8331,"journal":{"name":"Archives of Physiology and Biochemistry","volume":" ","pages":"1-10"},"PeriodicalIF":2.5,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142943384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This abstract explores the intricate interplay between three essential pathways: The Triggering Pathway, The Metabolic Amplifying Pathway, and Cellular Transduction, in orchestrating glucose-dependent biphasic insulin secretion.Mechanism: During the triggering pathway, glucose metabolism in pancreatic beta-cells leads to ATP production, closing ATP-sensitive potassium channels and initiating insulin exocytosis. The metabolic amplifying pathway enhances insulin secretion via key metabolites like NADH and glutamate, enhancing calcium influx and insulin granule exocytosis. Additionally, the cellular transduction pathway involves G-protein coupled receptors and cyclic AMP, modulating insulin secretion.Result and conclusion: These interconnected pathways ensure a dynamic insulin response to fluctuating glucose levels, with the initial rapid phase and the subsequent sustained phase. Understanding these pathways' complexities provides crucial insights into insulin dysregulation in diabetes and highlights potential therapeutic targets to restore glucose-dependent insulin secretion.","PeriodicalId":8331,"journal":{"name":"Archives of Physiology and Biochemistry","volume":" ","pages":"854-865"},"PeriodicalIF":2.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139401617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Western blot analysis was used to detect protein levels and co-immunoprecipitation (Co-IP) was used to detect the association between the proteins.

This data have shown that BPA induces lipid metabolism dysfunction and pyroptosis by upregulating O-GlcNAc transferase (OGT) level. NLRP3 directly interacts with OGT, and elevated OGT enhanced the stability of NLRP3 protein. BPA promoted OGT-mediated O-GlcNAcylation to stabilised NLRP3, thus accelerating NAFLD progress in vitro.
