Abstract:Objective To study the regulatory mechanism of cannabinoid receptor 1 (CB1) on the lipid metabolism of diet-induced obese mice.Methods The C57BL/6J male mice were feed with high-fat diet, and then the effect of rimonabant on the body mass, liver mass and serum biochemical index of mice were detected. In particular, the mRNA levels ofCB1 and carnitine palmitoyltransterase-1(CPT1), and protein levels of CB1 in subcutaneous fat, visceral fat, skeletal muscle, liver and heart were also tested. Results It was showed the body mass and liver mass, as well as the mRNA and protein levels of CB1 were all significantly decreased in rimonabant-treated mice (P<0.05). Simultaneously, the levels of total cholesterol, high density lipoprotein, adiponectin and leptin were improved (P<0.05). Furthermore, the mRNA levels of carnitine palmitoyltransterase-1A (CPT1A) and carnitine palmitoyltransterase-1B (CPT1B) in each tissue were increased, while no obviously difference was detected in the expression ofCPT1A andCPT1B in mouse heart. Conclusion It was suggested that CB1 can regulate lipid metabolism by controlling the expression ofCPT1A andCPT1B genes. A basis for clinical treatment of lipid metabolism disorders was provided.
