CDH1 and lung carcinoma: The results of Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis indicated that Cdh1-related genes were enriched in the following pathway in LUAD group, including Wnt signaling pathway, Tight junction, regulation of actin cytoskeleton, mTOR signaling pathway, MAPK signaling pathway, focal adhesion and cell cycle pathway (Figure 3D and Figure 3E) which are well characterized oncogenic pathways for human cancer, including lung cancer.
