AMP激活的蛋白激酶(AMPK)是细胞能量状态的感受器。它由一种需要肿瘤抑制因子LKB1的机制激活,通过代谢应激增加细胞内ADP:ATP和/或AMP:ATP的比率。一旦激活,它就会启动产生三磷酸腺苷的分解代谢途径,同时关闭生物合成途径和细胞周期进程。这些效应表明AMPK激动剂可能对2型糖尿病和癌症的治疗和/或预防有用。事实上,AMPK被药物二甲双胍和水杨酸盐激活,后者是阿司匹林的主要分解产物。二甲双胍被广泛用于治疗糖尿病,而流行病学证据表明,二甲双胍和阿司匹林都能预防癌症。我们综述了这些药物和其他药物以及从传统草药中提取的天然产物激活AMPK的机制。
The AMP-activated protein kinase (AMPK) is a sensor of cellular energy status. It is activated, by a mechanism requiring the tumor suppressor LKB1, by metabolic stresses that increase cellular ADP:ATP and/or AMP:ATP ratios. Once activated, it switches on catabolic pathways that generate ATP, while switching off biosynthetic pathways and cell cycle progress. These effects suggest that AMPK activators might be useful for treatment and/or prevention of type 2 diabetes and cancer. Indeed, AMPK is activated by the drugs metformin and salicylate, the latter being the major breakdown product of aspirin. Metformin is widely used to treat diabetes, while there is epidemiological evidence that both metformin and aspirin provide protection against cancer. We review the mechanisms of AMPK activation by these and other drugs, and by natural products derived from traditional herbal medicines.
