SRC and breast cancer: No significant difference was detected in total Src and p-Y416Src expression and subcellular localization between African American TNBC (n = 33) and African American ER+BC (n = 21) cases (Fig. 2B), although African American TNBC exhibited a trend towards an increase in the expression of cytoplasmic total Src (P = 0.060) and membrane p-Y416Src (P = 0.095) as compared to African American ER+BC.
