Consistent with this, ICAM1 protein levels were also detected at much higher levels in human TNBC cell lines, such as MDA-MB-231, BT-549, FC-IBC-0233, and EMF-0133, as compared with MCF-7 luminal breast cancer cells via flow cytometry or immunoblotting (Supplementary Fig. 1e–f), as well as in murine TNBC cell lines E0771 and 4T1 (Supplementary Fig. 1g). Here, ICAM1 is linked to breast carcinoma.
