1 In addition, high PA levels reduced the expression of Sirtuin 3 (SIRT3) and phosphorylated AMP-activated protein kinase (AMPK), while the AMPK activator, AICAR, restored mitochondrial function as well as oocyte ability and reduced the acetylation of mitochondrial protein. Palmitic Acid protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens

3 Our results indicated that PA induces ceramide accumulation and downregulates the AMPK/SIRT3 pathway causing mitochondrial protein hyperacetylation and dysfunction in oocytes. Palmitic Acid protein kinase AMP-activated catalytic subunit alpha 2 Homo sapiens
