KRT5 and cancer: High cytoplasmic BRCA1 expression was positively associated with basal like cancer (χ2 = 8.6, P b = 0.003) and basal cell markers CK5/6 (χ2 = 5.5, P b = 0.013) and EGFR (χ2 = 4.5, P b = 0.04) as well as Ki67 index (χ2 = 6.0, P b = 0.017), bcl2 (χ2 = 5.0, P b = 0.017), and nuclear AR expression (χ2 = 4.1, P b = 0.03).
