125I irradiation induced expression changes of DNA methyltransferases mRNA in SW-1990 cells. DNMT1 (A), DNMT3a (B), and DNMT3b (C) mRNA expression in 125I irradiated SW-1990 cells was detected as described in the Materials and Methods section. *P < 0.05 compared with the 0 Gy (Control) group. #P < 0.05 compared with the 2 Gy group. ΔP > 0.05 compared with the 0 Gy group.
