项目摘要
In mammals, hundreds of thousands of oocytes are contained in adult ovaries, and small part of oocytes restart meiosis in each estrous cycle. More than 99% of follicles are regenerated as atresia, however, molecular control mechanism to select ovulating oocytes which is an important strategy to get excellent offspring has not been revealed. The present study performed to elucidate the molecular control mechanism that regulates a selective killing of ovarian follicles in porcine ovaries, in other words, to examine the apoptosis regulating molecular mechanism in granulosa cells. I analyzed the transmission system of apoptotic signal in granulosa cells. I revealed that granulosa cell was a type II apoptosis cell in which apoptotic signal transduced via mitochondria. I found that a novel soluble receptor, an outside factor of cell membrane, inhibited cell death in garnulosa cells. Moreover, I demonstrated two inhibitors, cFLIP and XIAP, which interrupted apoptotic signaling within the cells. For application of these apoptosis inhibiting factors, I created the rescue system for potential oocytes in frozen small ovarian tissues by apoptosis inhibitory factor gene transfer and xenotransplantation techniques to raise the follicle survival rate.
在哺乳动物中,成体卵巢中含有数十万个卵母细胞,在每个发情周期中,有一小部分卵母细胞重新开始减数分裂。99%以上的卵泡再生为闭锁,但选择排卵卵母细胞作为获得优良后代的重要策略的分子调控机制尚不清楚。本研究旨在阐明猪卵巢卵泡选择性杀伤的分子调控机制,即探讨颗粒细胞凋亡的分子调控机制。分析了颗粒细胞中凋亡信号的传递系统。我发现颗粒细胞是一种通过线粒体传递凋亡信号的II型凋亡细胞。我发现了一种新型的可溶性受体,一种细胞膜的外部因素,可以抑制大环细胞中的细胞死亡。此外,我还展示了两种抑制剂,cFLIP和XIAP,它们可以阻断细胞内的凋亡信号。为了应用这些凋亡抑制因子,本研究通过凋亡抑制因子基因转移和异种移植技术,建立了冷冻小卵巢组织中潜在卵母细胞的挽救系统,以提高卵泡存活率。
