Fig 1. The combinatorial effects of PCNA-I1S and Cs-137 irradiation on cell growth inhibition.

Fig 1

After irradiation with Cs-137 at 2 or 4 Gy, the cells were plated into 96-well plates (1,000 to 3,000 cells/well, 4 to 6 wells/treatment group) and allowed to attach for 3 hours. The cells were then treated with increasing concentrations of PCNA-I1S for 24 hours. After removing PCNA-I1S containing medium, the cells were then cultured in fresh medium for additional 72 hours and stained with MTT. Data shown are from one representative experiment of three. *, p<0.05 (Cs-137 irradiation alone vs. the combinations of Cs-137 irradiation and PCNA-I1S).
