Radiosensitizing effect of PARP-1 inhibitor Olaparib on MCF-7 breast cancer and hypoxic imaging / 中国药理学通报

Aim To investigate the radiosensitizing effect of the PARP inhibitor Olaparib on MCF-7 breast cancer model and to monitor the radiosensitizing effect of Olaparib by F-Fluoroerythronitroimidazole (F-FETNIM) PET/CT. Methods MCF-7 breast cancer model was established and divided into control group, Olaparib group, irradiation group and Olaparib + irradiation group according to random number table method; tumor volume was measured to calculate tumor inhibition rate and survival time of tumor-bearing mice was counted.
