Figure 6From: Artemisinin derivative artesunate induces radiosensitivity in cervical cancer cells in vitro and in vivoThe effect of ART on the apoptosis and cell cycle progression of HeLa xenografts. (A) Representative TUNEL assays showing apoptosis in HeLa xenografts(magnification, × 400). (B) Percentage of TUNEL-positive cells per field are expressed as means ± SEM. *P < 0.05, compared with radiation alone group. (C) The cell cycle distributions of the xenografts were analyzed. Values shown are the mean ± SEM. (D) Western blot analysis of Cyclin B1, Cdc2 and Wee1 in the HeLa xenografts.Back to article page
