Recombinant Human SIRT1

Background

SIRT1 is a NAD+-dependent deacetylase and member of the sirtuin family that regulates cellular processes including gene expression, metabolism, DNA repair, and aging by removing acetyl groups from target proteins SIRT1 is highly expressed in various tissues, including the liver, brain, and skeletal muscle, where it modulates the activity of transcription factors such as p53, FOXO, NF-κB, and PPARγ coactivator-1α (PGC-1α) SIRT1 promotes cellular survival during stress by enhancing DNA repair, suppressing apoptosis, and regulating energy metabolism through mitochondrial biogenesis and fatty acid oxidation Activation of SIRT1 is associated with increased longevity and protection against age-related diseases such as type 2 diabetes, cardiovascular disease, neurodegeneration, and cancer Compounds like resveratrol act as SIRT1 activators to improve metabolic health by enhancing insulin sensitivity and mitochondrial function SIRT1 also inhibits inflammation by deacetylating NF-κB and reducing pro-inflammatory cytokine production, making it a key target for therapies in metabolic, inflammatory, and age-associated disorders
