KEGG enrichment revealed that the EGFR family was related to the ERBB signaling pathway, glioma, non-small cell lung cancer pathways, neurotrophin signaling pathways, chronic myeloid leukemia pathways, random signaling pathways in microRNAs in cancer tissues, and cancer lycans signaling pathways. The gene discussed is BDNF; the disease is non-small cell lung carcinoma.
