FOXP2 and breast carcinoma: Based on this data set, we observed a weak correlation between the expressions of FOXA2 and FOXP2 in the samples (R=0.14, p=0.007), while a moderate correlation between their expressions was further found in the subgroup of basal breast cancer especially (n=98, R=0.34, p=0.001) (Figures 1H, I).
