EGCG抗肿瘤作用及其相关靶点的研究进展

摘要

Epigallocatechin gallate (EGCG)is the main bioactive component of green tea and is a polyphenolic sub-stance that belongs to the class of tea polyphenols.Over the years,it has been discovered that it has played a preven-tive and potential therapeutic role in anti-oxidation,anti-inflammatory,anti-cardiovascular diseases,anti-obesi-ty,anti-diabetic,anti-neurological diseases,anti-tumor,and so on.It can interact with multiple protein targets and affect various biological pathways to exert its biological effects.For example,direct binding to autophagy-related pro-tein LC3-I promotes the formation of LC3-II and promotes autophagy,acting on the PI3K/AKT pathway to affect cell autophagy,apoptosis,angiogenesis,and cell cycle regulation.Its anti-tumor role and its related targets are re-viewed.%表没食子儿茶素没食子酸酯(epigallocatechin gallate,EGCG)是绿茶的主要生物活性成分,是一种多酚类物质,属于茶多酚的一种.多年来研究发现其在抗氧化、抗炎、抗心血管疾病、抗肥胖、抗糖尿病、抗神经系统疾病、抗肿瘤等等方面发挥了预防及潜在的治疗作用,并可与多种蛋白靶点作用,影响多种化学通路发挥其上述生物学作用,如跟自噬相关蛋白LC3-I直接结合促进LC3-II的形成进而促进自噬,作用于PI3K/AKT通路影响细胞自噬、细胞凋亡、血管生成和细胞周期调控等等.现对其在抗肿瘤方面的作用及其相关靶点作一综述.
