Figure 5From: Increased betulinic acid induced cytotoxicity and radiosensitivity in glioma cells under hypoxic conditionsEffects of BA on radiosensitivity of glioma cells. U251MG (left) and U343MG (right) cells were either treated with 10, 20 or 25 μM BA and irradiated with a dose of 2 and 6 Gy under normoxic conditions (A, B), or treated with 5, 10 or 15 μM BA and irradiated with a dose of 6 and 15 Gy under hypoxic conditions (C, D) and compared to DMSO-treated control cells. Data represent the mean values (± SD) of three independent experiments.Back to article page
