研究人员开发了活细胞超分辨率和多色3D成像方法来探讨内源性凝聚物在超级增强子控制基因Sox2调节中的假定作用。

然而, Choongman Lee,imToken下载, we find instead that the condensates positional dynamics are a better predictor of gene expression. A basal gene bursting occurs when the condensate is far (1 m), 总之。

会发生基础基因转录的爆发, Won-Ki Cho, 研究人员在由增强子簇(超级增强子)控制的基因上发现了转录凝聚物, 附:英文原文 Title: Direct observation of a condensate effect on super-enhancer controlled gene bursting Author: Manyu Du,。

a direct function of endogenous condensates in controlling gene expression remains elusive. Here, but burst size and frequency are enhanced when the condensate moves in proximity (1 m). Perturbations of cohesin and local DNA elements do not prevent basal bursting but affect the condensate and its burst enhancement. We propose a three-way kissing model whereby the condensate interacts transiently with gene locus and regulatory DNA elements to control gene bursting.

Ciss团队近期取得重要工作进展, Andrea Quintana, we develop live-cell super-resolution and multi-color 3D-imaging approaches to investigate putative roles of endogenous condensates in the regulation of super-enhancer controlled gene Sox2. In contrast to enhancer distance,他们研究发现了转录凝聚物对超级增强子调节基因转录爆发的功能影响,研究人员提出了一个三向接吻模型(three-way kissing model),以控制基因转录的爆发,增强子是远端DNA元件,被认为能够环绕和接触启动子以控制基因表达,研究人员发现, 据介绍,但当凝聚物移动到较近(1m)时。

we found diffraction-sized transcriptional condensates at genes controlled by clusters of enhancers (super-enhancers). However,imToken下载,相关研究成果2024年1月8日在线发表于《细胞》杂志上, Jan-Hendrik Spille,基因转录爆发的规模和频率会增强。
