To evaluate the relationship between MSI2, VEGFR2, and VEGF-A in the subset of lung adenocarcinoma, we performed IHC analysis of MSI2, VEGFR2, and VEGF-A expression in an independent group of 116 non-squamous clinical tumor samples (Figure 4A,B, Supplementary Table S8). This evidence concerns the gene VEGFA and lung adenocarcinoma.
