Treatments preserve PPARγ activity and PPARγ responsive gene expression. (a) PPARγ mRNA relative expression in pooled liver samples from analyzed groups normalized to GAPDH expression. Results are expressed as mean ± SEM percentage of mean values obtained from equal numbers of C57BL/6J and C3He/6J mice. *P < 0.05. (b). SCARB1 mRNA relative expression in liver samples from analyzed groups normalized to GAPDH expression. *P < 0.05 (c). ChIP with a PPARγ antibody of study groups was used to amplify a SCARB1 promoter fragment. ChIP figures percentages indicate increments or decrements regarding C57BL/6J mice fed HFHC diet. Data of C57BL/6J mice fed chow diet was established as 100%.
