To assess the association of DDR1, RUNX1, and CBFβ expression levels in these breast cancer subtypes, we used METABRIC data from the Breast Cancer Integrative Platform (BCIP) to produce Kaplan-Meier curves stratifying the association between their expression and survival by breast cancer subtype, with non-TNBC representing luminal/HR+ cancers and TNBC representing basal-like cancers. This evidence concerns the gene CBFB and breast cancer.
