Effect of EMPA on protein expression on antioxidant enzymes in subcutaneous white adipose tissue in PCOS. Effect of EMPA on subcutaneous white adipose tissue (WAT) protein expression of A cytosolic superoxide dismutase (SOD1, ~ 18 kDa), B mitochondrial superoxide dismutase (SOD2, ~ 22 kDa), and C catalase (~ 60 kDa) after 3 weeks of EMPA treatment. Data were normalized by total protein content (TPC). Data are expressed as mean ± SEM and were analyzed by two-way ANOVA followed by Tukey post hoc tests. Significant interactions were observed for SOD1 and SOD2 in subcutaneous WAT. *P < 0.05. n = 3–4 per group
