Clonogenic assay of TPC-1 cells treated with harmine and radiation. (a) Inhibitory effect of different doses of harmine on the colony forming ability of TPC-1 cells. ∗∗ represents p < 0.01 versus 24 h group. # represents p < 0.01 versus 48 h group. (b) Radiosensitization effect of harmine (2 μg/mL) on TPC-1 cells. ∗∗ represents p < 0.01 versus radiation group.
