SIRT1 and AMPK are energy receptors in cells, regulating the activity of PGC-1α by means of phosphorylation and deacetylation. The regulation of the activity of the AMPK/SIRT1/PGC-1α axis directly affects the expression of its downstream genes related, being closely related to the occurrence and de-velopment of insulin resistance.
