  • Transcriptomic analyses identify association between mitotic kinases, PDZ-binding kinase and BUB1, and clinical outcome in breast cancer
    Ocaña, Alberto ...
    Protein kinases are important components in oncogenic transformation of breast cancer. Evaluation of upregulated genes that codify for protein kinases could be used as biomarkers to predict clinical ... outcome. Gene expression and functional analyses using public datasets were performed to identify differential gene expression and functions in basal-like tumors compared with normal breast tissue. Overall survival (OS) associated with upregulated genes was explored using the KM Plotter online tool. The prognostic influence of these genes in luminal tumors and systemically untreated patients was also assessed. Of the 426 transcripts identified in basal-like tumors, 11 genes that coded for components of protein kinases were upregulated with more than a fourfold change. Regulation of cell cycle was an enriched function containing 10 of these 11 identified genes. Among them, expression of four genes, BUB1beta, CDC28, NIMA, and PDZ binding kinase, were all associated with improved OS when using at least one probe in the basal-like subtype. Two genes, BUB1beta and PDZ binding kinase, showed consistent association with improved OS irrespective of the gene probe used for the analysis. No association was observed for these genes with relapse-free survival. In contrast, both BUB1beta and PDZ binding kinase showed worse OS in luminal tumors and in a cohort of systemically untreated patients. BUB1beta and PDZ binding kinase are associated with improved OS in basal-like tumors and worse OS in luminal and untreated patients. The association with a better outcome in basal-like tumors could be due to a more favorable response to chemotherapy.
