We previously showed that ketoisocaproic acid (KIC) suppressed insulin-stimulated glucose transport in L6 myotubes, especially in myotubes depleted of branched-chain ketoacid dehydrogenase (BCKD), the enzyme that decarboxylates BCKA. This suggests that upregulating BCKD activity might improve insulin sensitivity. We hypothesised that increasing BCAA catabolism would upregulate insulin-stimulated glucose transport and attenuate insulin resistance induced by BCKA. L6 myotubes were either depleted of BCKD kinase (BDK), the enzyme that inhibits BCKD activity, or treated with BT2, a BDK inhibitor. Myotubes were then treated with KIC (200 μM), leucine (150 μM), BCKA (200 μM), or BCAA (400 μM) and then treated with or without insulin (100 nM). BDK depletion/inhibition rescued the suppression of insulin-stimulated glucose transport by KIC/BCKA. This was consistent with the attenuation of IRS-1 (Ser612) and S6K1 (Thr389) phosphorylation but there was no effect on Akt (Ser473) phosphorylation. The effect of leucine or BCAA on these measures was not as pronounced and BT2 did not influence the effect. Induction of the mTORC1/IRS-1 (Ser612) axis abolished the attenuating effect of BT2 treatment on glucose transport in cells treated with KIC. Surprisingly, rapamycin co-treatment with BT2 and KIC further reduced glucose transport. Our data suggests that the suppression of insulin-stimulated glucose transport by KIC/BCKA in muscle is mediated by mTORC1/S6K1 signalling. This was attenuated by upregulating BCAA catabolic flux. Thus, interventions targeting BCAA metabolism may provide benefits against insulin resistance and its sequelae.</p>","PeriodicalId":47536,"journal":{"name":"Journal of Nutritional Science","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11503859/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142510355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The stratification variables were race, ethnicity (Afro-Colombian and Indigenous), and educational level (secondary or higher). Based on a literature review of qualitative studies that commonly explored food culture, nutritional status, and physical activity in analysing obesity within racial and ethnic populations, we incorporated these categories into our research methodology through semi-structured interviews. A framework analysis was used as a qualitative methodology to organise and analyse the collected data. We conducted 21 semi-structured interviews, 13 with the Afro-Colombian population and eight with indigenous inhabitants. The results indicate that cultural beliefs, forced displacement/migration, and alterations in public order have resulted in changes in food security, food culture, and physical activity practices, affecting the onset of obesity. Notably, distinctions in cultural beliefs regarding food culture and health as factors influencing obesity were observed between Afro-Colombians and the Indigenous populations; however, educational differences within the same racial ethnic group were not predominant.
