Our data indicated that the three treatment groups, including 2 Gy, CB11, and 2 Gy/CB11, did not change EMT marker expression in NSCLC cells; however, A549R and H460R cells regulated the EMT phenotype, indicating a decrease in E-cadherin and an increase in N-cadherin, vimentin, slug, and snail. This evidence concerns the gene SNAI1 and non-small cell lung carcinoma.
