Cells within tissues are subject to various mechanical forces, including hydrostatic pressure, shear stress, compression, and tension. These mechanical stimuli can be converted into biochemical signals through mechanoreceptors or cytoskeleton-dependent response processes, shaping the microenvironment and maintaining cellular physiological balance. Several studies have demonstrated the roles of Yes-associated protein (YAP) and its homolog transcriptional coactivator with PDZ-binding motif (TAZ) as mechanotransducers, exerting dynamic influence on cellular phenotypes including differentiation and disease pathogenesis. This regulatory function entails the involvement of the cytoskeleton, nucleoskeleton, integrin, focal adhesions (FAs), and the integration of multiple signaling pathways, including extracellular signal-regulated kinase (ERK), wingless/integrated (WNT), and Hippo signaling. Furthermore, emerging evidence substantiates the implication of long non-coding RNAs (lncRNAs) as mechanosensitive molecules in cellular mechanotransduction. In this review, we discuss the mechanisms through which YAP/TAZ and lncRNAs serve as effectors in responding to mechanical stimuli. Additionally, we summarize and elaborate on the crucial signal molecules involved in mechanotransduction.
组织内的细胞会受到各种机械力的影响,包括静水压力、切应力、压缩和张力。这些机械刺激可以通过机械感受器或细胞骨架依赖的反应过程转化为生化信号,从而塑造微环境并维持细胞生理平衡。多项研究表明,Yes 相关蛋白(YAP)及其同源转录共激活因子 PDZ 结合基序(TAZ)作为机械转导子的作用,对细胞表型的分化和疾病发病机制产生动态影响。这种调节功能需要细胞骨架、核骨架、整合素、黏着斑(FA)以及多个信号通路的整合,包括细胞外信号调节激酶(ERK)、无翅型(WNT)和 Hippo 信号通路。此外,新出现的证据证实了长链非编码 RNA(lncRNA)作为细胞机械转导中机械敏感分子的作用。在这篇综述中,我们讨论了 YAP/TAZ 和 lncRNA 作为机械刺激反应中的效应物的机制。此外,我们还总结并详细阐述了机械转导中涉及的关键信号分子。
