Fatty acid oxidation and lipogenesis
WebDuring cancer, reprogramming of lipid metabolism results from several processes, such as increased fatty acid uptake, de novo lipogenesis, beta-oxidation of fatty acids, and … WebPharmacological intervention with rapamycin alleviated the ability of alcohol to up-regulate lipogenesis, to down-regulate fatty acid oxidation, and to induce steatogenic phenotypes. Chronic-plus-binge ethanol feeding led to activation of SREBP-1 and lipin 1 through S6K1-dependent and independent mechanisms.

CPT1 activity is inhibited by malonyl-CoA, the product of acetyl-CoA carboxylase (ACC)-2 in mitochondria ( 3 ).
WebFeb 9, 2013 · De novo lipogenesis: palmitic acid is newly synthesized from glucose. Acetyl-CoA carboxylase (ACC) and fatty acid synthase (FAS) catalyze the rate-limiting and final steps, respectively. After ACS … WebSecond, basic studies have verified that RBP4 is involved in the pathogenesis of NAFLD by inducing hepatic de novo lipogenesis, impairing fatty acid oxidation, exaggerating …
WebIncreased malonyl-CoA might decrease CPT-1 activity to suppress hepatic fatty acid oxidation [ 11 ]. Thus, reduced adiponectin levels might play a key role on hepatic lipogenesis and fatty acid oxidation after chronic ethanol consumption.
