Beside, our differential analysis of RNAseq showed that KDM5A was elevated in TNBC, and the low expression of KDM5A indicated higher survival rate among TNBC patients, which was consistent with the study reporting that high mRNA level of RBP2 was correlated with early and high incidence of tumor metastasis in breast cancer (Cao et al. 2014). This evidence concerns the gene RBP2 and breast cancer.
