From: Knockdown of PKM2 enhances radiosensitivity of cervical cancer cells
PKM2 expression was associated with radiation resistance. Representative examples of PKM2 staining of cervical cancers in the radiation-resistant group and radiation-sensitive group. a Weak positive staining of PKM2 in the radiation-sensitive group. b Strong positive staining of PKM2 in the radiation-resistant group. c, d HeLa and SiHa cells were cultured for 24 h after 0, 2, 4, 6, and 8 Gy of X-ray irradiation. Total protein were extracted and analyzed through Western blot. e, f HeLa and SiHa cells were cultured for 24 h after 0, 2, 4, 6, and 8 Gy of X-ray irradiation. Total RNA were extracted and analyzed through quantitative RT-PCR. Data represent three independent experiments. **P < 0.01, ***P < 0.001 compared with the 0 Gy group
