Consistently with the HPA database (Fig. 1B) and previous studies, CD44 [29], integrin β1 [30], EphA2 [31], myoferlin [32] and liprin β1 [33] were found expressed at higher levels in TNBC cells compared to non-TNBC BC cells, with CD44 and integrin β1 strongly enriched in chemoresistant cells [10] (Fig. 1C and D). Here, EPHA2 is linked to breast cancer.
