Provided herein are methods and compositions for modulating the activity of sirtuin deacetylase protein family members; p53 activity; apoptosis; lifespan and sensitivity to stress of cells and organisms. Exemplary methods comprise contacting a cell with an activating compound, such as a flavone, stilbene, flavanone, isoflavone, catechin, chalcone, tannin or anthocyanidin; or an inhibitory compound, such as a sphingolipid, e.g., sphingosine. Also disclosed herein are methods for treating, preventing or diagnosing a disease associated with neuronal cell death, e.g., a neurodegenerative disease.
本文提供了调节sirtuin去乙酰化酶蛋白家族成员、p53活性、细胞和生物的凋亡、寿命和对压力的敏感性的方法和组合物。举例来说,方法包括使用激活化合物(如黄酮类、苯乙烯类、黄酮酮类、异黄酮类、儿茶素、查尔酮、单宁或花青素)或抑制化合物(如鞘脂类,例如鞘氨醇)与细胞接触。本文还公开了治疗、预防或诊断与神经元细胞死亡相关的疾病(例如神经退行性疾病)的方法。
