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.
本文提供了一种调节sirtuin去乙酰化酶蛋白家族成员、p53活性、细胞和生物的凋亡、寿命和对压力敏感性的方法和组合物。其中一种示例方法包括使用活化化合物(如黄酮、双苯乙烯、黄烷酮、异黄酮、儿茶素、查尔酮、单宁或花青素)或抑制化合物(如鞘脂类化合物,例如鞘氨醇)与细胞接触。
