Relative protein expression of PGC-1α in nuclear and cytoplasmic extractions of the renal cortex of mice. (A) Western blot analysis of PGC-1α protein expression in the nuclear and cytoplasmic extractions of renal cortexes from mice after 8 weeks treatment. (B) Relative quantification of protein expression from the results of the western blot analysis. Each bar represents the relative mean ± standard deviation, with the control group expression values set as 1. n=6 per group. *P<0.05, as indicated. PGC-1α, peroxisome proliferator-activated receptor γ coactivator-1α; DKD, diabetic kidney disease; RGZ, rosiglitazone.
