摘要 细胞外基质(extra cellular matrix,ECM)是存在于细胞与细胞之间的结缔组织。基质金属蛋白酶类(matrix metallopro-teinases,MMPs)是由多种锌离子依赖性酶组成的能降解细胞外基质蛋白的重要酶类,其活性在基因转录、酶原活化和活化后调节3个方面受到机体的调控。在肿瘤组织中,MMPs的表达很广泛。MMPs可促进肿瘤的生长、调节肿瘤细胞的凋亡,通过降解ECM促进新生血管生成及调节细胞之间黏附等机制促进肿瘤的浸润、侵袭和转移,帮助肿瘤细胞逃避机体的免疫。总之,MMP是一类与肿瘤关系十分密切的蛋白水解酶,通过对MMPs及MMPs抑制剂的研究,人们在肿瘤生物学和肿瘤治疗方面都取得了较大的进步。
