Skeletal muscle tissue RNA-Seq and RRBS in T2D, Obese and Active subjects
We performed RNA-Seq on skeletal muscle tissue in Active individuals, indivduals with obesity (Obese) and individuals with obesity and T2D (T2D) (n =6 per group). PCA of top ranked contributing genes show clear separation of the Active group from Obese and T2D with considerable overlap between Obese and T2D. Over-representation analysis highlighted that Active had an upregulation of genes related to respiration/mitochondrial capacity in comparison to Obese and T2D. RRBS was performed on skeletal muscle tissue from a subset of participants from each group (n = 3). Data was analyzed to reveal (DMS) differentially methylated sites located at differentially expressed genes related to mitochondrial respiration/function. Out of a combined 488 DMS related to mitochondrial related differentially expressed genes, 11% were significantly positively correlated with gene expression and 12% were significantly negatively associated with gene expression. Significantly correlated DMS were mainly located in the promoter and 1st intron region Overall design: Skeletal muscle tissue from M. Vastus Lateralis was obtained from lean Active individuals, individuals with Obesity and individuals with T2D and Obesity to perfrom transcriptomics by RNA-Seq and DNA methylation by RRBS.
