Abstract The five isoforms of the long-chain acyl-CoA synthases (ACSL) are associated with different roles in the regulation of fatty acid metabolism, promotion of cell proliferation and apoptosis, and development of diseases. The effects of ACSL on fatty acid metabolism are well documented; however, their roles in controlling obesity metabolism must be better investigated. Therefore, this project will verify the effects of adipocyte-specific ACSL4 knockout on metabolic parameters, body composition, insulin sensitivity, plasma levels of insulin, b-hydroxybutyrate, triglyceride, and cholesterol, adipocyte lipolysis, number and size of adipocytes, and genes related to energy expenditure, inflammation, lipid metabolism and white adipose tissue differentiation in diet-induced obese mice. Mice lacking ACSL4 in adipocyte tissue and control mice will be caged and fed a low-fat (LFD) or high-fat diet (HFD) for 12 weeks. Data will be compared using an unpaired two-tailed Student's t-test, and significance will be set a P < 0.05.Keywords: ACSL4; white adipose tissue; lipolysis; oxygen consumption; molecular biology.
