From: Correction to: Axin gene methylation status correlates with radiosensitivity of lung cancer cells
The effect of X-ray irradiation on lung cancer cells with hypermethylated or unmethylated Axin gene. a shows the effect of X-ray irradiation on cell apoptosis in lung cancer cells by flow cytometric analysis. The histogram in b summarizes the statistical data from a. The rate of colony formation in H157 and LTE cells with or without X-ray irradiation are shown in c, and the histogram in d summarizes the statistical data from c. The invasive cell numbers in H157 and LTE cells (treated or untreated with X-ray) are presented in e, f is the histogram of e. The cell apoptosis rate, colony formation rate and cell invasiveness are markedly changed when H157 and LTE cell lines are treated with X-ray irradiation, with a more prominent inhibitory effect seen in the H157 cell line than in the LTE cell line (a- f). * P < 0.05, comparison between the two cell lines
