Living organisms can detect and respond to physical forces at the cellular level. The pathways that transmit these forces to the nucleus allow cells to react quickly and consistently to environmental changes. Mechanobiology involves the interaction between physical forces and biological processes and is crucial for driving embryonic development and adapting to environmental cues during adulthood. Molecular studies have shown that cells can sense mechanical signals directly through membrane receptors linked to the cytoskeleton or indirectly through biochemical cascades that can influence gene expression for environmental adaptation. This review will explore the role of epigenetic modifications, emphasizing the 3D genome architecture and nuclear structures as responders to mechanical stimuli, which ensure cellular memory and adaptability. Understanding how mechanical cues are transduced and regulate cell functioning, governing processes such as cell programming and reprogramming, is essential for advancing our knowledge of human diseases.
生物体能在细胞水平上检测和响应物理力。传递这些力到细胞核的途径使细胞能够快速且一致地对环境变化做出反应。机械生物学涉及物理力与生物过程的相互作用,对于驱动胚胎发育和成年期适应环境线索至关重要。分子研究表明,细胞可以通过与细胞骨架相连的膜受体直接感知机械信号,或通过可以影响环境适应的基因表达的生化级联反应间接感知机械信号。本综述将探讨表观遗传修饰的作用,强调 3D 基因组结构和核结构作为机械刺激的响应者,以确保细胞记忆和适应性。了解机械线索如何转导并调节细胞功能,控制细胞编程和重编程等过程,对于增进我们对人类疾病的认识至关重要。
