Expression levels of both Notch1 and CD73 in BC cell lines were verified in an online database of sequenced patient samples (bc-GenExMiner v4.8), the mRNA level of Notch1 and CD73 in TNBC subtype tumors was significantly higher than non-TNBC subtype counterparts (Supplement 1E,F). Here, NOTCH1 is linked to breast cancer.
