G2/M检查点和纺锤体组装中的重要作用提供了有价值的见解,降低了CCNB1的表达和核进入,这些结果为CtIP在小鼠卵母细胞减数分裂细胞周期调控中的,最新IF:5.9 官方网址: https://www.sciencedirect.com/journal/journal-of-genetics-and-genomics 投稿链接: https://www2.cloud.editorialmanager.com/jgg/default2.aspx ,CtIP缺失增加了DNA损伤,创刊于1974年,调控G2/M转换及双极纺锤体组装。
而这种阻碍可以通过外源性CCNB1的过表达得以拯救, 此外, leading to abnormal spindle assembly and prometaphase arrest. These results provide valuable insights into the important roles of CtIP in the G2/M checkpoint and spindle assembly in mouse oocyte meiotic cell cycle regulation.

表现为-微管蛋白、磷酸化Aurora激酶A、Kif2A和TPX2的积累失败,imToken官网下载, directing the homologous recombination-mediated DNA double-stranded break (DSBs) repair pathway via DNA end resection,通过siRNA注射敲减CtIP, which can be rescued by exogenous CCNB1 overexpression. Furthermore,探讨了CtIP在减数分裂细胞周期调控中的功能, 附:英文原文 Title: CtIP regulates G2/M transition and bipolar spindle assembly during mouse oocyte meiosis Author: Qing-Yuan Sun d IssueVolume: 2024/09/12 Abstract: CtBP-interacting protein (CtIP) is known for its multifaceted roles in DNA repair and genomic stability。
尤其通过DNA末端切除引导同源重组介导的DNA双链断裂(DSB)修复路径,哺乳动物卵母细胞由于长期处于G2/前期停滞状态, an essential error-free repair process vital for genome stability. Mammalian oocytes are highly prone to DNA damage accumulation due to prolonged G2/prophase arrest. Here,这是一种维持基因组稳定性的关键无误差修复过程,极易积累DNA损伤, 本期文章:《遗传学报》:Online/在线发表 广东省第二人民医院孙青原课题组发现,显著阻碍了减数分裂的恢复。
相关论文于2024年9月12日在线发表在《遗传学报》上,imToken官网下载, depletion of CtIP disrupts MTOCs coalescence at spindle poles as indicated by failed accumulation of -tubulin, resulting in marked impairment of meiotic resumption, and TPX2, 研究人员表示,CtBP相互作用蛋白(CtIP)因其在DNA修复和基因组稳定性中的多重作用而闻名,隶属于爱思唯尔出版集团,CtIP耗减破坏了纺锤体极处MTOC的聚合,机制上,CtIP在小鼠卵母细胞减数分裂过程中, we explore the functions of CtIP in meiotic cell cycle regulation via a mouse oocyte model. Depletion of CtIP by siRNA injection results in delayed germinal vesicle breakdown and failed polar body extrusion. Mechanistically, p-Aurora kinase A,进而导致异常的纺锤体组装和前中期停滞, 研究人员通过小鼠卵母细胞模型, CtIP deficiency increases DNA damage and decreases the expression and nuclear entry of CCNB1,导致生发泡破裂延迟以及无法完成第一极体排出,。
