基质金属蛋白酶对胃癌微环境调控作用的研究进展

Research Progress of Promoting Function of Matrix Metalloproteinases in Gastric Cancer via Regulating Microenvironment

目的介绍基质金属蛋白酶(MMPs)在胃癌发生、发展中的作用。方法收集近年来国内、外有关MMPs与胃癌关系的文献并作综述。结果胃癌的发生、发展是多步骤、多因素的复杂过程,其病因和发病机理仍未完全阐明。MMPs是一类蛋白水解酶,它们通过对肿瘤生长的微环境进行调控,进而在胃癌演进中的增殖、转移、新生血管形成和调控肿瘤细胞及其周围正常细胞凋亡的过程中均起着重要的作用。结论MMPs从不同的方面促进胃癌的演进,了解这些方面的机理可以为未来胃癌的治疗提供理论依据。

Objective To summarize the role of matrix metalloproteinases （MMPs） in occurrence and development of gastric cancer. Methods Domestic and international publications online involving MMPs of gastric cancer in recent years were collected and reviewed. Results The occurrence and development of gastric cancer was a multi- step and multi factorial complicated progress, whose etiology and pathogenesis were still unclarified. MMPs were a class of proteolytic enzymes, which played an important role in the proliferation, metastasis, angiogenesis of gastric cancer and apoptosis of tumor cells and their surrounding normal cells by regulating the microenvironment of the growth of tumor. Conclusion MMPs promote the evolution of gastric cancer in variable ways, the mechanisms of which should he comprehended to provide a theoretical basis for the future treatment of gastric cancer.
