CYP17A1 and polycystic ovary syndrome: The control-RSV group was excluded from the gene expression analysis since we did not detect any significant metabolic or reproductive changes in this group compared to the control-vehicle group. Cyp17a1 was upregulated and Cyp11a1 was downregulated in PCOS-vehicle rats compared to vehicle controls, but neither exercise nor resveratrol treatment had any affect on the gene expression levels (Table 5).
