EGFR and neoplasm: Also, many tumor-associated pathways were enriched such as the Wnt, MAPK, and PI3K-AKT signaling pathways, EGFR tyrosine kinase inhibitor resistance, etc. GO and KEGG pathway analyses of the DEGs in ceRNA network also involved in several pathways associated with cancer, such as RAS, Wnt, MAPK, and PI3K-AKT signaling pathways.
