Figure 4From: Aberrant DNA methyltransferase expression in pancreatic ductal adenocarcinoma development and progressionEffects of DNMT1 and DNMT3b siRNA on cell viability (A), apoptosis (B) and cell cycle distribution (C). a, p < 0.05 compared with the untreated cells. b, p < 0.05 compared with the negative siRNA-transfected cells. The data are shown as the mean ± SD of eight independent experiments.Back to article page
