Transfecting CAFs with SNAI1 enhanced the modulatory effects of CAFs on lung cancer cell EMT when CAFs were co-cultured with A549 and H1299 cells, whereas transfecting CAFs with si-SNAI1 attenuated the modulatory effects of CAFs on lung cancer cell EMT (Figure 7G–7I). This evidence concerns the gene SNAI1 and lung carcinoma.
