Significant pathways related breast cancer, such as melanoma (p-value < 0.001), breast cancer (p-value = 0.009), and microRNAs in cancer (p-value = 0.009) in the BCMT group, p53 signaling pathway (p-value < 0.001), autophagy, and EGFR tyrosine kinase inhibitor resistance in MCMT group, were observed from KEGG analysis results. The gene discussed is TP53; the disease is breast cancer.
