Objective To investigate the relation of interaction of signal transducer and activator of transcription 1( STAT1) and CD74/CD44 in the regulation of epithelial-mesenchymal transition of colon cancer cells. Methods The eukaryotic expression plasmids of STAT1 and CD74/CD44 and the expression plasmid of epithelial-mesenchymal transition tyrosine kinase receptor DDR2 promoter luciferase report gene were constructed. The eukaryotic expression plasmids STAT1 and CD74/CD44 were transfected into colon cancer cells...
