AURKB and breast cancer: We further analyzed the gene expression data of all the breast cancer cell lines available from the Klijn et al. study.24 The AURKB and ZAK gene expression levels were significantly higher in TNBC than in non-TNBC cell lines (two-sided Wilcoxon rank sum test, p < 10−5, Supplementary Fig. 8, Supplementary Data 15), suggesting that AURKB and ZAK targets are up-regulated in TNBC.
