Effect of 6-week treatment with Allium fistulosum aqueous extract (AFW) and A. fistulosum ethanolic extract (AFE) on gene expression in epididymal adipose tissue of high-fat diet (HFD)-induced obese mice. Expression levels of (a) adenosine monophosphate-activated protein kinase (AMPK) isoforms AMPKα1, (b) AMPKα2, (c) leptin, (d) adiponectin, (e) uncoupling protein 2 (UCP2), and (f) peroxisome proliferator-activated receptor gamma (PPAR-γ), as assessed by real-time reverse-transcription polymerase chain reaction (RT-PCR). Normal, standard chow; HFD-control, HFD only; HFD-HCA, HFD plus 100 mg/kg Garcinia cambogia extract containing hydroxycitric acid; HFD-CLA, HFD plus 100 mg/kg conjugated linoleic acid; HFD-ORL, HFD plus 15.6 mg/kg Xenical (orlistat); HFD-AFW, HFD plus 100 mg/kg AFW; HFD-AFE, HFD plus 100 mg/kg AFE. Results are expressed as the mean ± standard error of the mean (SEM) (n = 6). # p < 0.05 compared with the normal control group; * p < 0.05, ** p < 0.01 compared with the HFD-control group
