Fig 4.

Effect of resveratrol on cao-1, cao-2, and al-2 expression. Real-time RT-PCR analyses of cao-1, cao-2, and al-2 mRNA in the wild type grown in the absence of resveratrol or exposed to the indicated concentrations of resveratrol for 15 min, 30 min, 1 h, 2 h, and 4 h. The effect of parallel addition of the equivalent amount of ethanol is shown as a control (open symbols). Levels are relative to the value of each gene before the addition of resveratrol or ethanol. All data show averages and standard deviations of four measurements from two independent experiments.
