Feeding the diabetes mellitus (DM) mice with the RSV‐enriched diet inhibited mitophagy in the quadriceps muscle. A) Representative western blots using antibodies against NIP3‐like protein X (BNIP3L), PTEN‐induced putative kinase‐1 (PINK1), p‐Parkin, Parkin, and voltage‐dependent anion channel (VDAC). After quantification, the B) BNIP3L/VDAC, C) PINK‐1/VDAC, and D) p‐Parkin (S65)/Parkin ratios were calculated in mice fed either the control (CTL) or RSV‐enriched diet. The mitochondrial protein VDAC was used as a loading control. Data are expressed as fold change versus CTL and reported as mean ± SD, n = 4–6 per group; *p < 0.05; **p < 0.01 between CTL and DM groups. #p < 0.05; ##p < 0.01 between DM and DM+RSV groups.
