RBBP4 promotes colon cancer malignant progression via regulating Wnt/β-catenin pathway

Figure 3 RBBP4 knockdown inhibits apoptosis of colon cancer cell lines. A: Apoptosis of SW620 cells examined by flow cytometry with the Annexin V-FITC/propidium iodide kit. The cells in the Q4 quadrant were defined as the apoptotic cells; B: Apoptosis of HCT116 cells examined by flow cytometry with the Annexin V-FITC/propidium iodide kit; C: Western blotting examination for apoptotic proteins. ^bP < 0.01 vs controls.
