As an important intracellular genetic and regulatory center, the nucleus is not only a terminal effector of intracellular biochemical signals, but also has a significant impact on cell function and phenotype through direct or indirect regulation of nuclear mechanistic cues after the cell senses and responds to mechanical stimuli. The nucleus relies on chromatin-nuclear membrane-cytoskeleton infrastructure to couple signal transduction, and responds to these mechanical stimuli in the intracellular and extracellular physical microenvironments. Changes in the morphological structure of the nucleus are the most intuitive manifestation of this mechanical response cascades and are the basis for the direct response of the nucleus to mechanical stimuli. Based on such relationships of the nucleus with cell behavior and phenotype, abnormal nuclear morphological changes are widely used in clinical practice as disease diagnostic tools. This review article highlights the latest advances in how nuclear morphology responds and adapts to mechanical stimuli. Additionally, this article will shed light on the factors that mechanically regulate nuclear morphology as well as the tumor physio-pathological processes involved in nuclear morphology and the underlying mechanobiological mechanisms. It provides new insights into the mechanisms that nuclear mechanics regulates disease development and its use as a potential target for diagnosis and treatment.
作为重要的细胞内遗传和调控中心,细胞核不仅是细胞内生化信号的终端效应器,而且在细胞感知并响应机械刺激后,通过直接或间接调节核机械信号对细胞功能和表型产生重大影响。细胞核依靠染色质-核膜-细胞骨架基础设施来耦合信号转导,并在细胞内和细胞外物理微环境中对这些机械刺激作出反应。细胞核形态结构的变化是这种机械反应级联的最直观表现,也是细胞核对机械刺激直接反应的基础。基于细胞核与细胞行为和表型的这种关系,异常的核形态变化在临床实践中被广泛用作疾病诊断工具。这篇综述文章重点介绍了核形态如何响应和适应机械刺激的最新进展。此外,本文将阐明机械调节核形态的因素以及涉及核形态的肿瘤生理病理过程和潜在的力学生物学机制。它为核力学调节疾病发展的机制及其作为诊断和治疗潜在靶点的应用提供了新的见解。
