X连锁细胞凋亡抑制剂(XIAP)表达的增加和卵泡细胞凋亡的抑制是FSH调节卵泡发育的重要决定因素。本研究的目的是探讨核因子-κB (NFκB) 在体外促性腺控制颗粒细胞 XIAP 表达和卵泡生长中的作用和调节。 FSH (100 ng/ml) 增加大鼠颗粒细胞 XIAP mRNA 丰度和蛋白质含量。促性腺激素还诱导含有 p65 亚基的颗粒细胞 NFκB 从细胞质易位到细胞核,并增加 NFκB-DNA 结合活性。 Supershift EMSA 表明 FSH 激活的 NFκB 包含 p65 和 p50 亚基。与 TNFα 不同,FSH 未能在体外引起颗粒细胞磷酸化和总抑制性 NFκB (IκB) IκB 含量的显着变化,并且显性失活 IκB 表达无法有效阻止促性腺激素诱导的 NFκB-DNA 结合活性和 XIAP 蛋白含量的增加。相比之下,SN50(一种细胞渗透...
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...
