miRNAs regulate SIRT1 expression during mouse embryonic stem cell differentiation and in adult mouse tissues
17 Jul 2010
Abstract excerpt
SIRT1 is increasingly recognized as a critical regulator of stress responses, replicative senescence, inflammation, metabolism, and aging. SIRT1 expression is regulated transcriptionally and post-transcriptionally, and its enzymatic activity is controlled by NAD+ levels and interacting proteins. We found that SIRT1 protein levels were much higher in mouse embryonic stem cells (mESCs) than in differentiated...
