Figure 2. The hepatic inflammatory microenvironment promoted the epithelial–mesenchymal transition (EMT) of lung adenocarcinoma cells. (A) The expression level of E-cadherin and vimentin in A549 and H1975 cells was detected by laser confocal scanning microscopy. (B) Changes in CDH1 and VIM mRNA expression in A549 and H1975 cells were detected by real-time PCR (*P<0.05 versus the control group).
