表没食子儿茶素没食子酸酯抗癌分子机制及其应用的研究进展
|
摘要
表没食子儿茶素没食子酸酯(epigallocatechin-3-gallate,EGCG)作为绿茶的主要成分之一,具有多种生物活性,体内外实验广泛证实EGCG具有抗癌活性。EGCG抗癌分子机制较复杂,可通过多种途径抑制癌细胞生长或诱导癌细胞凋亡。从抗氧化、促氧化、阻滞肿瘤细胞周期、抑制肿瘤细胞血管生成、诱导癌细胞凋亡及调控microRNA等方面综述EGCG的抗癌分子机制,对提高EGCG生物利用度的3种策略,即纳米包装技术、协同联用和分子修饰进行概述,并对今后EGCG的抗癌作用的研发进行展望。
Epigallocatechin-3-gallate(EGCG), as one of the main components of green tea, has a variety of biological activities. Both in vitro and in vivo experiments widely demonstrate that EGCG has anticancer activities. The molecular mechanism of EGCG against cancer was much complicated, and EGCG suppressed tumor cell proliferation and/or induced cell apoptosis through multi-pathways.This paper reviewed the anticancer molecular mechanism of EGCG, including EGCG anti-oxidantion, prooxidation, retardant of tumor cell cycle, inhibition of tumor cell angiogenesis, inducement of cancer cell apoptosis, and regulation of micro RNA, summarized the research progress of three strategies for improving bioavailability of EGCG: nano-packaging technology, synergistic application and molecular modification, and looked into research and development on anticancer activity of EGCG.
