Increased X-linked inhibitor of apoptosis (XIAP) expression and suppressed follicular apoptosis are important determinants in the regulation of follicular development by FSH. The objective of the present study was to examine the role and regulation of nuclear factor-κB (NFκB) in the gonadotropic control of granulosa cell XIAP expression and follicular growth in vitro. FSH (100 ng/ml) increased rat granulosa cell XIAP mRNA abundance and protein content. The gonadotropin also induced granulosa cell p65 subunit-containing NFκB translocation from cytoplasm to nucleus and increased NFκB-DNA binding activity. Supershift EMSA indicated the FSH-activated NFκB contained p65 and p50 subunits. Unlike TNFα, FSH failed to elicit a significant change in granulosa cell phospho- and total-inhibitory NFκB (IκB) IκB contents in vitro and dominant-negative IκB expression was ineffective in blocking the increase in NFκB-DNA-binding activity and XIAP protein content induced by the gonadotropin. In contrast, SN50 (a cell perme...
