Results are expressed as –fold variation over the appropriate control groups; ND240 indicate fold increase over ND, normal diet control group and HFD60, HFD120, HFD240 and HFDMET indicate fold increase over HFD, high-fat diet control group. Fold variations less than one were expressed as negative numbers (e.g., a –fold variation of 0.50 is expressed as −2.00). Values expressed are means ± S.D of triplicate measurements. Statistical significance was calculated based on the mean ΔCT values by DMRT for only mice fed with high-fat diet with or without GE. For same gene with different treatment groups, means in the different rows with different alphabets (a-d) were significantly different (p<0.05).
