Abstract

Lipid catabolism dysfunctions and consequent accumulation of these substrates in the liver are related to increase the generation of reactive oxygen species (ROS) and the development of metabolic diseases. Recently we described the participation of very long chain acyl-CoA dehydrogenases (VLCADs) on ROS generation by liver mitochondria of animals treated with high fat diet (Cardoso, under review). Those enzymes are members of flavoproteins family, acyl-CoA dehydrogenases, which catalyze the limiting step of beta-oxidation and enable electron transfer to electron transport chain. However, the mechanisms of regulation have not been totally completely elucidated. Our project aims to study the mechanisms of generation of ROS by VLCADs in animals treated with high fat diet.
