Mechanical forces are known to influence cellular processes with consequences at the cellular and physiological level. The cell nucleus is the largest and stiffest organelle, and it is connected to the cytoskeleton for proper cellular function. The connection between the nucleus and the cytoskeleton is in most cases mediated by the linker of nucleoskeleton and cytoskeleton (LINC) complex. Not surprisingly, the nucleus and the associated cytoskeleton are implicated in multiple mechanotransduction pathways important for cellular activities. Herein, we review recent advances describing how the LINC complex, the nuclear lamina, and nuclear pore complexes are involved in nuclear mechanotransduction. We will also discuss how the perinuclear actin cytoskeleton is important for the regulation of nuclear mechanotransduction. Additionally, we discuss the relevance of nuclear mechanotransduction for cell migration, development, and how nuclear mechanotransduction impairment leads to multiple disorders.
机械力已知会影响细胞过程,从而在细胞和生理水平上产生后果。细胞核是最大和最硬的细胞器,它通过核骨架和细胞骨架连接以实现适当的细胞功能。细胞核与细胞骨架之间的连接通常由核骨架和细胞骨架的连接(LINC)复合物介导。毫不奇怪,细胞核和相关的细胞骨架参与了多个机械转导途径,这些途径对于细胞活动很重要。在此,我们综述了最近的进展,描述了 LINC 复合物、核纤层和核孔复合物如何参与核机械转导。我们还将讨论核周肌动蛋白细胞骨架如何重要调节核机械转导。此外,我们还讨论了核机械转导对于细胞迁移、发育的相关性,以及核机械转导受损如何导致多种疾病。
