RASSF-1a methylation change vs. change in (A) trans-resveratrol and (B) NAF PGE2 concentration. Linear regression using least squares for model fitting was performed. RASSF-1a methylation significantly decreased as the concentration of total trans-resveratrol increased (P = 0.047, r2 = −0.14), and as PGE2 decreased (P = 0.045, r2 = 0.18).
