Obesity and non-alcoholic fatty liver diseases are a growing issue worldwide. Decreased expression of CYP2B6 is associated with obesity in humans and Cyp2b-null mice are diet-induced obese; however fatty liver disease is worse in humanized CYP2B6 transgenic mice than WT or Cyp2b-null mice despite lower obesity. CYP2B6 produces several oxylipins with preference for metabolism at the 9- and 13-positions with 9-HODE and 13-HODE (from linoleic acid; n-6), and 9-HOTrE and 13-HOTrE (from a-linolenic acid; n-3) preferentially produced. Oxylipins serve as signaling molecules for many processes, such as inflammatory pathways, lipid distribution, and lipid metabolism. Due to their diversity, oxylipins can …
