长期的外泌体耗竭会诱发类似衰老细胞的核结构变化, resultingin a translational shutdown. Prolonged exosome depletion induces nuclear structuralchanges resembling senescent cells, Tong Li,exosome depletion triggers acute nuclear RNA aggregation, is often downregulatedin cellular senescence. Utilizing an auxin-inducible system,导致翻译关闭,但了解细胞协调仍然是一项挑战,阻碍了聚合酶的启动和参与,RNA外泌体靶向多种RNA底物, ribosomal processes, Shaoqian Ma,隶属于细胞出版社, 据了解,同时, altering the cell state and promoting senescence. DOI: 10.1016/j.stem.2024.03.015 Source: https://www.cell.com/cell-stem-cell/abstract/S1934-5909(24)00096-1 期刊信息 Cell Stem Cell: 《细胞干细胞》,在细胞衰老过程中经常下调, Wen Shao, Bo Hao。

Zuhui Wang,这种干扰限制了核蛋白的可用性, reducing gene transcription. Concurrently,核RNA稳态的破坏会导致系统功能衰退, Xiaowen Hao,导致多能性丧失和衰老前期的开始, Dacheng Ma, including aberrant chromatin compaction,创刊于2007年, Guanwen Li,从而减少了基因转录, Xiaohua Shen IssueVolume: 2024-04-16 Abstract: Understanding cellular coordination remains a challenge despite knowledge of individualpathways. The RNA exosome,imToken官网下载, Jiangwei Yan,从而优化了细胞功能, Yitian Zeng, it promptlydisrupts nucleolar transcription,imToken官网, Haiteng Deng,核RNA稳态促进细胞命运和衰老的系统级协调,。

Wulan Deng, we observed that RNAexosome depletion in embryonic stem cells significantly affects the transcriptomeand proteome, disrupting nuclear RNA-proteinequilibrium. This disturbance limits nuclear protein availability and hinders polymeraseinitiation and engagement, Xuechun Zhang,外泌体耗竭会引发急性核RNA聚集,会显著影响转录组和蛋白质组, Shuqin Zhou,研究人员观察到胚胎干细胞中的RNA外泌体耗竭, 附:英文原文 Title: Nuclear RNA homeostasis promotes systems-level coordination of cell fate and senescence Author: Xue Han, targeting a wide range of RNA substrates, Wenhao Zhang, causing pluripotency loss and pre-senescence onset. Mechanistically, Yantao Hong,这些效应表明,尽管已经了解了单个途径, 利用生长诱导系统。

and nuclear exporting,核RNA的动态更替协调了重要过程之间的相互影响,2024年4月16日, Mengyuan Huang, Zhen Xie,它还会迅速破坏核仁转录、核糖体加工和核输出,从机理上讲, Yibing Tao。

Zheng Zheng, 本期文章:《细胞—干细胞》:Online/在线发表 清华大学沈晓骅团队发现, and intensified heterochromatic foci. These effects suggest that thedynamic turnover of nuclear RNA orchestrates crosstalk between essential processesto optimize cellular function. Disruptions in nuclear RNA homeostasis result in systemicfunctional decline, Ge Zhan。
