As shown in Fig. 2, compared with Ctl individuals, patients in the PCOS group exhibited decreased expression of progesterone (0.667 ± 0.096 versus 1.000 ± 0.047 for PCOS versus Ctl groups, respectively; P < 0.01; n = 8; Fig. 3A) and STAR (0.631 ± 0.100 versus 1.000 ± 0.130 for PCOS versus Ctl, respectively; P < 0.05; n = 7; Fig. 3B). This evidence concerns the gene STAR and polycystic ovary syndrome.
