Vitamin D receptor expression in primary myotubes correlates with characteristics of lipid metabolism in vitro. Lipid metabolism was assessed by radioactive assays, using saturated14C-labeled palmitic fatty acid, and normalized to protein content. VDR, Vitamin D receptor; Fox, fatty acid oxidation. Individual complexes of mitochondrial oxidative phosphorylation (OxPHOS) are presented as % from the total signal, obtained as a sum of signals of all 5 protein complexes (immunoblotting). The bivariate relationships between variables were assessed using the Pearson correlation coefficient. Points colour scheme: white – HC, light grey—IIM before PT, dark grey – IIM after PT PT – personal training
