Regulation of aromatase activity, between Sc and Om adipocytes, by cortisol (F) and insulin (500 nm) in males (A) (Sc n = 9; Om n = 9) and females (B) (n = 17; n = 10, respectively). Activity is expressed as mean ± sem pmol/mg protein·h. Statistical analysis compared basal with treatments using ANOVA (*, P < 0.05; **, P < 0.001).
