摘　　要：FAS是一种在多种细胞中表达的膜蛋白受体,与其配体FASL结合后激活细胞内下游信号,可导致一种细胞程序性死亡——凋亡。在很多细胞类型中,FAS诱导的凋亡是抑制或杀灭肿瘤细胞的重要因素。近年来发现,在某些细胞微环境条件或肿瘤类型中,FAS可激活与凋亡相反的生物学功能,包括促进细胞的增生和迁移等。但目前对于FAS介导的非凋亡通路的作用和机理尚不完全清楚,与经典凋亡通路的关系也缺乏研究,其在什么条件下、在哪些细胞或肿瘤类型中起作用也有待深入调查。简述了FAS信号在肿瘤细胞中介导的促增生作用,重点总结了其介导非凋亡通路中的几个关键因子以及在临床肿瘤治疗上的应用,以期为肿瘤的临床新治疗方法和新药研究提供思路。FAS is a membrane protein receptor expressed in a variety of cells.After binding to its ligand FASL,the downstream signal in cells is activated,which can lead to a kind of programmed cell death-apoptosis.Fas-induced apoptosis is an important factor in inhibiting or killing tumor cells in many cell types.In recent years,it has been found that FAS can activate biological functions opposite to apoptosis in certain cellular microenvironment conditions or tumor types,including cell proliferation and migration.However,the role and mechanism of Fas-mediated non-apoptotic pathway are not completely clear,and the relationship between Fasmediated non-apoptotic pathway and classical apoptotic pathway is also lack of research.Further investigation is needed to determine under what conditions and in which cells or tumor types Fas-mediated non-apoptotic pathway plays a role.This review described the proliferative effect of FAS-mediated non-apoptotic signaling pathway in tumor cells,with a focus on summarizing several key factors in its non-apoptotic pathway,aiming at providing idea for the new clinical treatment methods and new drug research in tumors.
