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.
本文提供了一些方法和组合物,用于调节sirtuin去乙酰化酶蛋白家族成员的活性,p53活性,细胞和生物的细胞凋亡,寿命和对压力的敏感性。其中一些方法包括使用激活化合物(如黄酮,斯蒂尔本,黄烷酮,异黄酮,儿茶素,查尔酮,单宁或花青素)或抑制化合物(如鞘脂,例如鞘氨醇)与细胞接触。
