Expression of PTEN in H-157 cells after irradiation treatment. (A) The H-157 cells which exposed to 1, 2, 4, 6, 8, and 10 Gy of X-rays were analyzed as shown in right panel. After irradiation, the cells were incubated for 6 h, and then were examined. (B) After incubation of X-irradiated (6 Gy) cells for 3, 6, 9 and 12 h, the PTEN protein was examined by Western blotting. Irradiation Treatment was shown to increase PTEN levels in H-157 cell lines tested, and H-157 cells exposing to 4~6 Gy expressed major amounts of PTEN.
