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.
本文提供了用于调节 sirtuin 去乙酰化酶家族成员活性、p53 活性、细胞凋亡、寿命以及细胞和生物体对应激的敏感性的方法和组合物。示例性方法包括使细胞与激活化合物接触,如黄酮、链烯、黄烷酮、异黄酮、儿茶素、查尔酮、单宁或花青素;或与抑制化合物接触,如鞘磷脂,如鞘磷脂。
