KRT5 and breast carcinoma: On the evaluation of these two transcription factors with other important immunohistochemical markers in breast cancer, we found a strong inverse association with basal-like phenotype markers – namely, CK14 (P = 0.007, P = 0.0002), CK5 (P = 0.027, P < 0.0001), vimentin (P = 0.003, P = 0.0006) and P-cadherin (P = 0.012, P < 0.0001) for FOXA1 and GATA-3, respectively.
