Since the anti-inflammatory, antidiabetic and hypolipidemic effects of soy isoflavones may be mediated by activation of peroxisome proliferator-activated receptors (PPAR), the present study investigated whether the methanolic fractions obtained from soybean seeds (E1) and soybean seed coats with hypocotyls (E2) could influence PPAR?, PPAR? and PPAR?/? transcriptional activity. The isoflavones from E1 and E2 were quantified by HPLC analysis. E1 and E2 were rich in isoflavones (daidzin, glycitin, genistin, malonyldaidzin, malonylglycitin, malonylgenistin, daidzein, glycitein, and genistein). Moreover, E1 and E2 showed no evidence of genetically modified material containing the gene CP4 EPSPS. To investigate PPAR transcriptional activity, human promonocytic U-937 cells were treated with E1 and E2 (200, 400, 800, and 1600 ?g/mL), positive controls or vehicle. Data are reported as fold-activation of the luciferase reporter driven by the PPAR-responsive element. Doseresponse analysis revealed that E1 and E2 induced the transcriptional activity of PPAR? (P < 0.001), with activation comparable to that obtained with 0.1 mM bezafibrate (positive control) at 1600 ?g/mL (4-fold) and 800 ?g/mL (9-fold), respectively. In addition, dose-response analysis revealed that E1 and E2 activated PPAR?/? (P < 0.05), and the activation at 800 ?g/mL (4- and 9-fold, respectively) was comparable to that of 0.1 mM bezafibrate (positive control). However, no effect on PPAR? was observed. Activation of PPAR? is consistent with the lipid-lowering activity of soy isoflavones in vivo, but further studies are needed to determine the physiological significance of PPAR?/? activation.
