Figure 6.

Expression of the DNA damage-repair protein (A) increased following radiation (C, control with no radiation; 1 h, 1 h post-irradiation with 4 Gy; and 3 h, 3 h post-irradiation with 4 Gy) and (B) decreased following mTOR inhibition by Rap (blank group, PBS only; 4 Gy group; 4 Gy + DMSO group; Rap group, 200 nmol/l Rap only; and 4 Gy + Rap group, 4 Gy + 200 nmol/l Rap). DNA-PKcs, DNA-dependent protein kinase catalytic subunit; DMSO, dimethyl sulfoxide; Rap, rapamycin; PBS, phosphate-buffered saline.
