Muscle expression of MYH7 (encoding MHC I, slow-oxidative type 1 fibres) and MYH2 (encoding MHC IIa, fast-oxidative type 2a fibres) did not differ between groups, but the expression of MYH1 (encoding MHC IIx, glycolytic type 2x fibres) tended (p = 0.061) to be increased in patients with T2D (Supplementary Table S3). Here, MYH7 is linked to type 2 diabetes mellitus.
