Western blotting analyses on whole liver protein samples were performed as previously described [31 (link)]. The separated proteins on the PVDF membranes were detected using the following antibodies: mouse monoclonal antibodies against ubiquinol-cytochrome c reductase, Rieske iron-sulfur polypeptide 1 (anti-Uqcrfs1 [5A5] ab14746), ubiquinol-cytochrome C reductase core protein I (anti-Uqcrc1 [16D10AD9AH5] ab110252), ubiquinol-cytochrome C reductase core protein II (anti-Uqcrc2 [13G12AF12BB11] ab14745) from Abcam (Cambridge, MA, USA) and mouse monoclonal antibody β-actin (A5441) from Sigma-Aldrich (Oakville, ON, Canada).
