| Outline of Final Research Achievements |
We examined the mechanism of regulation of LH-receptor expression in granulosa cell of rat ovary. Under normal physiological conditions, IL-6 is produced in granulosa cells, but some studies have suggested that IL-6 negatively affects reproductive functions in the ovary. Our previous study showed that FSH upregulates LH-receptor expression. We examined the effect of IL-6 on FSH-induced LHR mRNA and protein expression levels and mechanisms of regulation in rat primary granulosa cells. Our results indicated that IL-6 increased FSH-induced expression of LHR. We also studied the effect of TNFα, and our results indicated TNFα decreased FSH-induced expression of LHR.
