Specifically, we found a significant inverse correlation between AURKB expression and IC50 of PTX in basal‐like subtype, the majority of which belong to TNBC (r = −0.9171, p = 0.0013), but not luminal breast cancer cell lines (r = −0.2609, p = 0.6175) (Figure 4G). This evidence concerns the gene AURKB and breast cancer.
