| Popis: | Rats treated with bezafibrate, a PPAR activator, gain less body weight and increase daily food intake. Previously, we have related these changes to a shift of thermogenesis from brown adipose tissue to white adipose tissue attributable to bezafibrate, which induces uncoupling proteins (UCP), UCP-1 and UCP-3, in rat white adipocytes. Nevertheless, UCP induction was weak, implying additional mechanisms in the change of energy homeostasis produced by bezafibrate. Here we show that bezafibrate, in addition to inducing UCPs, modifies energy homeostasis by directly inducing aco gene expression and peroxisomal fatty acid β-oxidation in white adipose tissue. Further, bezafibrate significantly reduced plasma triglyceride and leptin concentrations, without modifying the levels of PPARγ or ob gene in white adipose tissue. These results indicate that bezafibrate reduces the amount of fatty acids available for triglyceride synthesis in white adipose tissue. |
