摘要: Sestrins由应激诱导产生,是在进化上相对保守的蛋白家族,能抑制氧化应激、调节腺苷酸活化蛋白激酶(AMPK)-哺乳动物雷帕霉素作用靶点(mTOR)通路来保护细胞和器官免受应激、老化带来的生理损伤。低氧、缺乏ATP可诱导Sesn2的表达。Sestrin在血糖稳态调节方面意义重大。Sestrins也参与延缓衰老、抑制年龄相关性疾病。

Abstract: Sestrins constitue the protein family which are evolutionarily consvered and stress inducible,they suppress the oxidative stress and regulate adenosine monophosphate-dependent protein kinase (AMPK)- mammalian target of rapamycin (mTOR) signaling and protect cells and organisms from stress and age-related physiological abnormalities.Hypoxia and ATP deficiency induce Sesn2 expression.Sestrins regulation of blood sugar homeostasis is physiologically impotant.Sestrins also contribute to the attenuation of aging and suppression of age-associated diseases.

Key words: Sestrins, Oxidative stress, Metabolic disease, Aging
