Moreover, total Src and p-Y416Src expression in both ER+BC and TNBC did not exhibit significant differences in subcellular localization when comparing age (women of age≤50 and women of age >50) (Table S1A, B), tumor grade (1, 2 and 3) (Table S2A, B), or proliferation status (high and low Ki67 index) (Table S3A, B). Here, MKI67 is linked to breast cancer.
