Figure 7. Time-course changes in the expression of genes involved in ovarian steroidogenesis of 3-month-old control and PCOS-model mice at 0,48 and 56 h after PMSG injection and 4, 8, 12, 24, 48 h after hCG injection. Data were expressed relative to mRNA expression in the ovaries atdiestrus (=1.0). Different letters (a, b, c and d) indicate significant changes in the expression of each gene (p<0.05). *p<0.05 significant differencebetween PMSG-primed mice at 56 h with or without hCG. Straight line and dotted line indicate hCG treatment at 48 h after PMSG treatment andno hCG treatment, respectively. n=5 in each group.
