Fig. 2From: Knockdown of PKM2 enhances radiosensitivity of cervical cancer cellsKnockdown of PKM2 expression enhanced the radiosensitivity of HeLa and SiHa cells in vitro. a, b Cells were irradiated at different doses of irradiation, and the CCK-8 assay was used to test the viability of these cells. c, d Radiation sensitivity was tested using colony formation assays. Knockdown of PKM2 decreased clonogenic formation in HeLa and SiHa cells compared with control. e, f Survival curves were obtained using a multitarget click mathematical model. Data represent three independent experiments. *P < 0.05, ***P < 0.001Back to article page
