摘要(Abstract):
目的:探讨Egr-1、Gadd45α在小鼠卵泡发育不同阶段的表达及其相互关系。方法:选择不同发育阶段的昆明种小鼠卵巢,用免疫组化法检测不同发育阶段卵泡中Egr-1、Gadd45α蛋白的表达。结果:Egr-1、Gadd45α蛋白在卵泡不同发育阶段的卵母细胞及颗粒细胞中均有表达,而且随卵泡发育表达增强。卵泡不同发育阶段中卵母细胞及颗粒细胞中Egr-1、Gadd45α蛋白表达差异有统计学意义(P<0.05)。闭锁卵泡Egr-1、Gadd45α蛋白表达强烈,其表达强度明显高于各级生长卵泡。黄体及间质中亦有Egr-1、Gadd45α表达。同时Egr-1、Gadd45α在各级卵母细胞的表达有较强的相关性(rs=0.993,P<0.05)。结论:卵泡发育不同阶段Egr-1、Gadd45α均有表达,在卵泡发育后期和闭锁卵泡中强表达。提示Egr-1、Gadd45α在卵泡生长发育及闭锁过程中可能起重要的调控作用。
