We compared the effects of resveratrol and rosiglitazone, alone and in combination, on indices of fatty acid re-esterification in cultured adipose tissue from obese participants (n = 17) undergoing gastric bypass. Rosiglitazone induced PDK4 and PEPCK gene expression to a greater extent than resveratrol. Co-treatment with both compounds induced PDK4 and PEPCK expression in parallel with reductions in the fatty acid to glycerol ratio. Our findings suggest beneficial effects of resveratrol and rosiglitazone co-treatment.
