HIF1A and carcinoma: Rapid increase in the level of Rad51 protein at 30 minutes following irradiation in glycolysis stimulated (DNP treated) cells observed here (Figure 6) is similar to the observations in the radio-resistant spheroids of DU145 carcinoma cell line [36]; which also interestingly has a significant level of HIF1α with elevated glycolysis and increased resistance to radiation [37].
