Berberine displays antitumor activity in esophageal cancer cells in vitro

Figure 3 Berberine promotes apoptosis in KYSE-70 cells. A: KYSE-70 cells were treated with 50 μmol/L berberine for 12 and 24 h. Apoptotic rates were measured using flow cytometry; B: Apoptotic cell values are expressed as mean ± SE of three experiments. ^aP < 0.05, ^bP < 0.01 vs controls.
