Notably, high mRNA expression of both Notch3 and GSK3β predicted greater relapse-free survival in overall (p = 1.8 × 10−5) and luminal A breast cancer patients (p = 0.0082; Figure 6C,F), but not luminal B, basal-like or Her 2 subtypes (Figure 6I,L,O). This evidence concerns the gene NOTCH3 and breast carcinoma.
