WebOct 31, 2024 · Consequently, activated SIRT6 in the cytoplasm interacts with ACSL5 and increases its enzyme activity by deacetylating ACSL5 at K98, K361, and K367. Activation of ACSL5 by SIRT6 elevates fatty acid-CoA production, stimulates mitochondrial fatty acid oxidation, and maintains hepatic lipid homeostasis. ... To determine the in vivo functional ... WebJan 22, 2024 · Via its enzymatic activity, SIRT6 enhances PDH expression and activity, OXPHOS, ATP/AMP ratio, and intracellular calcium concentration, while reducing AMPK activation, in BC cells. Thus, overall, SIRT6 inhibition appears as a viable strategy for preventing or treating BC. Background
