Effect of Ying Yang 1 (YY1) on cell radiosensitivity in TE‐1 cells. Clonogenic cell survival curves were generated for TE‐1 cells that were stably transfected with the indicated vectors and were then exposed to 2, 4, 6 or 8 Gy X‐ray irradiation. The survival data were normalized to those of the non‐irradiated control group. The SER was calculated for TE‐1 cells that were transfected with the YY1 overexpression vector (pcDNA3.1‐YY1). The values shown are for three independent experiments.
