液-液相分离(LLPS)是一种生物物理过程,介导细胞过程的精确和复杂的时空协调。蛋白质和核酸通过LLPS被分隔成微米级的无膜液滴。这些液滴,称为生物分子凝聚物,是高度动态的,具有浓缩的组分,并执行特定的功能。已经观察到生物分子浓缩物组织多种关键生物过程,包括基因转录、信号转导、DNA损伤修复、染色质组织和自噬。由于异常LLPS导致的这些生物活性的失调在心血管疾病中是重要的。本文综述了生物分子凝聚物的调节和功能,全面描述了LLPS在几种常见心血管疾病中的作用,并讨论了调节LLPS在心血管疾病中的革命性治疗前景和与LLPS相关的新治疗策略。
Liquid–liquid phase separation (LLPS) is a biophysical process that mediates the precise and complex spatiotemporal coordination of cellular processes. Proteins and nucleic acids are compartmentalized into micron-scale membrane-less droplets via LLPS. These droplets, termed biomolecular condensates, are highly dynamic, have concentrated components, and perform specific functions. Biomolecular condensates have been observed to organize diverse key biological processes, including gene transcription, signal transduction, DNA damage repair, chromatin organization, and autophagy. The dysregulation of these biological activities owing to aberrant LLPS is important in cardiovascular diseases. This review provides a detailed overview of the regulation and functions of biomolecular condensates, provides a comprehensive depiction of LLPS in several common cardiovascular diseases, and discusses the revolutionary therapeutic perspective of modulating LLPS in cardiovascular diseases and new treatment strategies relevant to LLPS.
