WebApr 17, 2024 · In vitro study of cyanidin for its SIRT6 deacetylation activity has been conducted, and it has been found to be a potent SIRT6 stimulator with 55-fold maximum activity with an EC 50 value of 460 ± 20 µM. Using Western blots, the SIRT6 deacetylation activity of cyanidin was estimated using core histone and the residual levels of histone H3 … WebApr 20, 2024 · SIRT6, a nuclear protein and a special member of the sirtuin family, has the activity of ADP-ribosyl transferase and NAD + -dependent deacetylase and is involved in multiple biological functions including life span, inflammation, metabolism, and cancer. WebSirt6 is mainly known as a deacetylase of histones H3 and H4, an activity by which it changes chromatin density and regulates gene expression. The enzymatic activity of Sirt6, as well as of the other members of the sirtuins family, is dependent upon the binding of the cofactor nicotinamide adenine dinucleotide (NAD+). [8] pointing down hand
