Our findings from the KEGG pathway enrichment analyses reveal that miR-141-3p, miR-181b1-5p, and miR-23b-3p are mainly enriched in pathways in cancer, small-cell lung cancer, the ErbB-epidermal growth factor receptor (EGFR) signaling pathway, chronic myeloid leukemia, and mitogen-activated protein kinase (MAPK) signaling pathways. The gene discussed is EGFR; the disease is small cell lung carcinoma.
