平滑肌细胞骨架结构及其信号调节途径
The Cytoskeleton and Its Signal Regulation in Smooth Muscle Cells
【摘要】 平滑肌细胞骨架是一个复杂的动态性网络,是细胞生命活动不可缺少的细胞结构。Rho通过活化其下游靶分子促进应力纤维的形成,其中Rho-associated coiled-coil kinase(ROCK)和Dial在该过程中起关键作用;PKC通过在细胞内不同定位的亚型使细胞骨架蛋白磷酸化,发挥其调节细胞骨架重构的作用。两条信号转导途径通过Src途径相互联系,共同参与细胞骨架动力学的调节。
【Abstract】 The cytoskeleton of smooth muscle cells (SMC) is a complex and dynamic network, which is an essential cellular structure for cell survive. Rho-associated coiled-coil kinase (ROCK) and Dial, as the downstream targets of Rho, induce the formation of the stress fibres. Protein kinase C plays a key role during the reorganization of cytoskeleton by different isoforms on subcellular location. The Rho and PKC develop cross-talk through Src signal pathway, regulating the cytoskeleton of SMC.
