To determine whether ITGB1 contributes to NSCLC cell radioresistance by regulating EMT, we analysed the protein levels of epithelial (E-cadherin) and mesenchymal (N-cadherin, Vimentin, Snail, and Zeb1) markers in A549-shITGB1 and H522-ITGB1 cells. The gene discussed is ITGB1; the disease is non-small cell lung carcinoma.
