Figure 3From: Artemisinin derivative artesunate induces radiosensitivity in cervical cancer cells in vitro and in vivoInduction of apoptosis by ART and radiation in HeLa and SiHa cells. Cells were treated with ART for 24 h prior to treatment with 2 or 6 Gy irradiation. Apoptosis and necrosis were measured using propidium iodide (PI)/annexin-V double staining in (A) Hela and (B) SiHa cells. The data are shown as mean ± SEM for three independent experiments. Statistical analysis between the groups was determined by ANOVA; *P < 0.05.Back to article page
