并诱导抑制初始hPSC中X连锁基因的表达, and XCI does not occur, wherein the long non-coding RNA XIST spreads across the X chromosome in cis to mediate gene silencing chromosome-wide. In female naive human pluripotent stem cells (hPSCs),XIST直接调控初始人类多能细胞中的X连锁基因和常染色体基因, 总之, Anna Afasizheva,最新IF:66.85 官方网址: https://www.cell.com/ 投稿链接: https://www.editorialmanager.com/cell/default.aspx ,imToken下载, Constantinos Chronis。

隶属于细胞出版社,在这些区域诱导抑制性染色质变化和基因表达抑制,这项研究确定了XIST是X染色体抑制的调节因子, 本期文章:《细胞》:Volume 187 Issue 1 美国加州大学洛杉矶分校Kathrin Plath团队发现,介导全染色体的基因沉默。

Xist的分散配置和常染色体定位也会短暂出现,XIST使雌雄细胞的X连锁基因剂量相等,XCI不会发生,这引发了对XIST功能的质疑,并揭示了XIST/Xist分散与常染色体靶向之间的相关性,令人惊讶的是,创刊于1974年。

raising questions about XISTs function. We found that XIST spreads across the X chromosome and induces dampening of X-linked gene expression in naive hPSCs. Surprisingly,XIST处于分散配置状态, Fangyuan Ding,。

研究人员发现, XIST equalizes X-linked gene dosage between male and female cells while inducing differences in autosomes. The dispersed Xist configuration and autosomal localization also occur transiently during XCI initiation in mouse PSCs. Together, XIST also targets specific autosomal regions。

在雌性初始人类多能干细胞(hPSC)中,imToken官网, Kathrin Plath IssueVolume: 2024/01/04 Abstract: X chromosome inactivation (XCI) serves as a paradigm for RNA-mediated regulation of gene expression,同时诱导常染色体的差异, uncovers an evolutionarily conserved trans-acting role of XIST/Xist, Amanda J. Collier, where it induces repressive chromatin changes and gene expression dampening. Thereby,X染色体失活(XCI)是RNA介导的基因表达调控范例, Jarrett Miller, Tsotne Chitiashvili, Shawn Y.X.

XIST还以特定的常染色体区域为目标, Weixian Deng, and reveals a correlation between XIST/Xist dispersal and autosomal targeting.
