Journal ArticleDOI

TL;DR: It is shown that conditional knockout (cKO) of Mtor in either primordial or growing oocytes caused infertility but differentially affected oocyte quality, granulosa cell fate, and follicular development.
Journal ArticleDOI
Oocyte-dependent activation of MTOR in cumulus cells controls the development and survival of cumulus-oocyte complexes.
Jing Guo,Lanying Shi,Xuhong Gong,Mengjie Jiang,Yaoxue Yin,Xiaoyun Zhang,Hong Yin,Hui Li,Chihiro Emori,Koji Sugiura,John J. Eppig,You-Qiang Su +11 more
TL;DR: By suppressing Ddit4l expression, thereby enabling MTOR activation in cumulus cells, oocytes promote cumulus cell development and survival, which in turn ensures the production of functionally normal eggs.
Journal ArticleDOI
Ribonuclease activity of MARF1 controls oocyte RNA homeostasis and genome integrity in mice.
Qingqing Yao,Guangyi Cao,Mingzhe Li,Baixing Wu,Xiaoyun Zhang,Teng Zhang,Jing Guo,Hong Yin,Lanying Shi,Jiayi Chen,Xiang Yu,Lina Zheng,Jinbiao Ma,You-Qiang Su +13 more
TL;DR: The crystal structures of key domains of MARF1 are resolved and it is demonstrated by biochemical and mutagenic analyses that the ribonuclease activity of MARf1 controls oocyte meiotic progression and retrotransposon surveillance.
