SIRT 1
SIRT-1 is a member of the sirtuin family of proteins involved in cellular stress response, metabolism, and longevity.
Function
SIRT-1 regulates gene expression through deacetylation. It impacts various cellular processes, including DNA repair, inflammation, and energy metabolism.
Significance
-
-
Aging and Longevity: SIRT-1 is associated with lifespan extension in model organisms. Caloric restriction activates SIRT-1 and promotes healthspan.
-
Metabolic Health: SIRT-1 influences glucose homeostasis, insulin sensitivity, and mitochondrial function.
-
Associated Diseases
Cancer and Neurodegeneration: Dysregulation of SIRT-1 is implicated in cancer, neurodegenerative diseases, and cardiovascular health.
