Cells and tissues generate and are exposed to various mechanical forces that act across a range of scales, from tissues to cells to organelles. Forces provide crucial signals to inform cell behaviour during development and adult tissue homeostasis, and alterations in forces and in their downstream mechanotransduction pathways can influence disease progression. Recent advances have been made in our understanding of the mechanisms by which forces regulate chromatin organization and state, and of the mechanosensitive transcription factors that respond to the physical properties of the cell microenvironment to coordinate gene expression, cell states and behaviours. These insights highlight the relevance of mechanosensitive transcriptional regulation to physiology, disease and emerging therapies.
细胞和组织产生并受到各种机械力的作用,这些力作用于不同的尺度,从组织到细胞到细胞器。力为细胞在发育和成人组织稳态过程中的行为提供了重要的信号,力及其下游机械转导途径的改变会影响疾病的进展。近年来,我们对力调节染色质组织和状态的机制以及对细胞微环境物理特性做出响应的机械敏感性转录因子有了更深入的理解,这些转录因子协调基因表达、细胞状态和行为。这些发现凸显了机械敏感性转录调控与生理学、疾病和新兴疗法的相关性。
