Western blot analysis and Reverse transcription PCR of ID1 and EMT related protein. a Western blot and b RT-PCR were used to detect the expression of ID1, E-cadherin, and vimentin in H1975 and H1975/OR cells. The mRNA and protein expression level of E-cadherin in H1975/OR cells was lower than that in H1975 cells, while the expression levels of ID1 and vimentin in H1975/OR cells were higher than those in H1975 cells. Representative results are shown from at least 3 independent experiments.*P < 0.05 versus H1975/OR
