By overlapping these upregulated genes identified in the second comparison (Ptend/dSmad4d/dErbb2d/d vs. Ptend/dSmad4d/d) with these ERBB2 negatively correlated genes, 117 and 87 genes were found in human lung adenocarcinoma (Table S12) and SCC (Table S13), respectively. This evidence concerns the gene ERBB2 and lung adenocarcinoma.
