Objective To analyze and validate the key molecular targets correlated with the overall survival of patients with HER2-positive breast cancer. Methods First, the survival time and transcriptome data of patients with HER2-positive breast cancer in stage Ⅰ/Ⅱ and Ⅲ/Ⅳ were downloaded from the TCGA database. The significantly differential genes between overall survival 8.5 years in stage Ⅰ/Ⅱ were picked out by edgeR package, and the pathways were enriched by KEGG. Similarly, the differential genes between overall survival 7 years in stage Ⅲ/Ⅳ were analyzed. Furthermore, KEGG pathway analysis was performed using the differential genes overlapped by stage Ⅰ/Ⅱ and Ⅲ/Ⅳ. Second, the relationships between the expression levels of key node genes and other genes in enriched pathway and the overall survival of patients with HER2-positive breast cancer were validated by KMplot database. Last, the correlation between the activity of pathway enriched in KEGG and the resistance to anti-HER2 treatment was validated in HER2-positive breast cancer cell line BT474. Results In patients with stage Ⅰ/Ⅱ HER2- positive breast cancer whose overall survival was |
