摘要: 肿瘤细胞在生长、浸润和转移过程中经历的缺氧、低糖等多种环境压力会对肿瘤细胞造成内质网应激,为应对内质网应激,肿瘤细胞会诱发未折叠蛋白反应(Unfolded protein response,UPR)。PERK通路作为激活UPR的一条关键通路可通过提高肿瘤对不良微环境的耐受程度、诱导新生血管生成、诱导自噬体形成、激活凋亡信号分子等促进肿瘤细胞生长、增殖、侵袭及保护性自噬,并且在UPR达到一定程度时诱导肿瘤细胞凋亡及自噬性死亡。

关键词: 内质网应激未折叠蛋白反应, 肿瘤细胞, PERK通路

Abstract: During growth,invasion and metastasis,tumor cells undergo endoplasmic reticulum stress(ERS)under hypoxia,hypoglycemia and other environmental stresses.In response to ERS,tumor cells induce unfolded protein response(UPR).PERK signaling pathway as a key pathway to activate UPR can promote survival,proliferation,invasion and protection of tumor cells by increasing tumor tolerance to adverse microenvironment,inducting angiogenesis,inducing autophagosome formation and activating apoptotic signal molecules.Tumor cells are induced apoptotic and autophagic death when UPR reaches a certain extent.

Key words: ERS, UPR, Tumor cells, PERK signaling pathway
