Apigenin induced apoptosis in Eca-109 cell. (A-C) Cells were treated with the indicated concentrations of apigenin, and the apoptosis was detected by FCM annexin V/PI staining. The protein expression levels were examined by Western blot, and GAPDH was used as loading control. (D–F) Cells were pretreated with 50 ng/µl IL-6, prior to the addition of indicated concentrations of apigenin, and the apoptosis was detected by FCM annexin V/PI staining. The protein expression was examined by Western blot. (A, D) the representative charts, (B, E) the quantified data, and (C, F) the Western blot results. *P < 0.05 and **P < 0.01 indicate significant difference as compared to the corresponding control (n = 3).
