Importantly, there was astrong positive correlation between the expression levels of KLF5 and RP1 in breast cancer tissues (P = 0.0316) (Fig. 6b).Consistently, the mRNA and protein levels of KLF5 were much higher in breastcancer cells, especially in TNBC cells, compared to MCF-10A cells (Fig.6c). This evidence concerns the gene RP1 and breast cancer.
