Introduction: Obesity is a major risk factor for the development of hyperlipidemia and its related cardiovascular complications. Apart from its well-established role in cancer biology, the MDM2-p53 axis has been recently shown to regulate glucose and lipid metabolism. Our preliminary data indicated that MDM2 is dramatically induced in the liver of obese mice. In this study, we aimed to investigate the potential role of hepatic MDM2 in controlling systemic lipid homeostasis usi...

Introduction: Adipocyte fatty acid binding protein (A-FABP) is a fatty acid chaperone that facilitates the efflux of free fatty acid from cytoplasm into circulation. Previous studies show that A-FABP knockout (KO) mice are more susceptible to diet-induced obesity comparing to wild type (WT) littermates. Here we investigate the underlying mechanism of A-FABP in the regulation of diet-induced obesity.Methods: A-FABP KO mice and their WT littermates were fe...

Introduction: We have previously demonstrated that APPL1 maintains glucose homeostasis by promoting both actions and secretion of insulin. Although APPL2 is a close homolog of APPL1, the physiological function of APPL2 is vaguely characterized. Thus, we generated a knockout (KO) mouse model in which APPL2 is deleted in pancreatic β-cells and hypothalamus (which is called APPL2 KO mice) to investigate its role in glucose and energy metabolism.Methods...

Introduction: Atherosclerosis is a chronic inflammatory arterial disease and is currently one of the most common causes of cardiovascular morbidity and mortality worldwide. Therefore, there is an urgent need to discover new therapeutic targets for treatment of this fatal chronic disease. Fatty acid binding protein 4 (FABP4), a pro-inflammatory adipokine that links obesity with its related metabolic diseases, has been implicated in the development of atherosclerosis. This study...
