摘要
Wnt信号通路包括经典通路和非经典通路,Wnt5a-Frizzled-2通路参与非经典通路中的Wnt/Ca2+信号通路,该通路由Wnt相关蛋白Wnt5a与其配体Frizzled-2结合后被激活,可调控细胞中的部分关键位点影响细胞的信号转导,且与细胞的生长进程密切相关.在某些血供丰富的组织,如心脏和脑组织等发生缺血再灌注时,均存在Wnt5a-Fizzled-2通路的激活.Wnt5a-Frizzled-2通路激活后引起细胞内钙超载,最终促进细胞凋亡.本文综述Wnt5a-Frizzled-2信号通路在缺血再灌注损伤类疾病中的异常激活和引起的钙超载导致细胞凋亡,以期为缺血再灌注损伤的生理机制研究提供参考.
Abstract
The Wnt signaling pathway includes both classical and non classical pathways,Wnt5a-Frizzled-2 pathway participates in the Wnt/Ca2+signaling pathway in the non-classical pathway,which is activated by the Wnt-related protein Wnt5a and its ligand Frizzled-2.It can regulate some key sites in cells to affect cell signal transduction,and is closely related to cell growth process.Activation of Wnt5a-Fizzled-2 pathway occurs in some tissues with abundant blood supply,such as heart and brain tissues,during ischemia-reperfusion.Activation of the Wnt5a-Frizzled-2 pathway causes these intracellular calcium overload,ultimately promoting apoptosis.This article reviews the abnormal activation of Wnt5a-Frizzled-2 signaling pathway in ischemia-reperfusion injury diseases and the induced calcium overload leading to apoptosis,in order to provide reference for the study of physiological mechanisms of ischemia-reperfusion injury.
