Figure 4From: Effect of DNA methylation inhibitor on RASSF1A genes expression in non-small cell lung cancer cell line A549 and A549DDPCell apoptosis detected by flow cytometry with FITC and PI staining. LL shows living cells (FITC-/PI-); UR shows necrotic cells (FITC+/PI+); LR shows apoptotic cells (FITC +/PI-); a: control group (0 μmol/L 5-Aza-CdR), b: 5 μmol/L 5-Aza-CdR, c: 10 μmol/L 5-Aza-CdR, d: 20 μmol/L 5-Aza-CdR.Back to article page
