Effects of 25 µM <i>trans</i>-resveratrol (RSV), <i>trans</i>-resveratrol-3-<i>O</i>-glucuronide (3G), <i>trans</i>-resveratrol-4′-<i>O</i>-glucuronide (4G) or <i>trans</i>-resveratrol-3-<i>O</i>-sulfate (S) on the mRNA expression (A) and protein concentration in the culture media (B) of adiponectin in 3T3-L1 maturing pre-adipocytes treated from day 0 to day 8 of differentiation.

<p>Values are means±SEM. Comparisons between each treatment with the control were analyzed by Student’s <i>t</i> test. The asterisks represent differences <i>vs.</i> the control (*<i>P</i><0.05, ***<i>P</i><0.001).
