Fig. 2. HRS/IRR phenomenon in human prostate cancer cells and pancreatic cancer cells. (a) The colony formation of human prostate cancer cells and pancreatic cancer cells irradiated with different doses. (b‒i) The plating efficiencies, survival fractions, and survival curves of human prostate cancer cells (b‒e) and human pancreatic cancer cells (f‒i). Values were presented as mean±SD (n=3). HRS: hyper-radiosensitivity; IRR: increased radioresistance; SD: standard deviation.
