Background: Pioglitazone increases insulin sensitivity and improves glycemic control in type 2 diabetics. In this study, we evaluated the effects of pioglitazone on the uncoupling protein 1 (UCP1) expression in mouse brown adipose tissue (BAT), and on recovery from oxidative stress due to a high-fat diet.

Methods: 30 mice were divided into three groups: group 1 received a normal diet, group 2 received a high-fat diet, and group 3 received a high-fat diet plus 30 mg/kg pioglitazone. After treatment, the cholesterol, triglyceride, paraoxonase 1 (PON1), total serum antioxidant capacity (TAC), malondialdehyde (MDA), and specific activity of hepatic catalase were measured. BAT UCP1 expression was evaluated at both the mRNA and protein levels.

Results: The weights differed between the groups (p<0.05). Serum MDA was greater and TAC, liver catalase, and PON1 were less than in group 2 than in group 1 (p<0.05). In Serum MDA was less and catalase activity was greater in group 3 than in group 2 (p<0.05). UCP1 gene expression was less in group 2 than in group 1 (p<0.05) but greater than in group 3 (p<0.05).

Conclusions: Pioglitazone may have a protective role in high-fat-diet-induced oxidative stress by increasing the antioxidant capacity. Moreover, it can induce weight loss by increasing UCP1 mRNA and protein expression.
