一、 研究方向

细胞代谢与表观遗传修饰在肿瘤与衰老中的作用。

肿瘤细胞在细胞代谢方面与正常细胞有着重大区别:正常细胞利用氧化磷酸化高效产生能量,而癌细胞却依赖有氧糖酵解而不是氧化磷酸化来产生能量。许多参与糖酵解的酶在癌细胞中特异性表达而且在癌细胞的生长增殖中起关键作用,已经成为肿瘤治疗的潜在靶位点。针对代谢酶开发的肿瘤治疗方法可以克服普通化疗产生的抗药性、促进化疗引起的癌细胞凋亡。然而,由于大多数代谢酶在肿瘤发生中的作用机制尚不完全清楚,肿瘤代谢治疗方法在应用方面受到了极大的限制。

近来研究表明细胞代谢包括代谢酶和代谢产物可以直接调控表观遗传修饰,比如DNA甲基化、组蛋白乙酰化、组蛋白甲基化等。表观遗传修饰在肿瘤发生和细胞衰老中起重要作用。更重要的是,表观遗传改变在理论上来讲是可逆的,因此有利于开发抗肿瘤和抗衰老的药物。为全面了解代谢酶的功能,本实验室主要以从下述三个方向进行研究:

1、细胞代谢酶以及代谢产物在肿瘤发生中的作用以及表观遗传调控机制。

2、细胞代谢酶以及代谢产物在衰老中的作用以及表观遗传调控机制。

3、抗肿瘤以及抗衰老药物的筛选与化学干预。
