By analyzing the data from 719 breast cancer samples in which the luminal is 566, Her2 + is 37, and TNBC is 116, we found that the expression of IL-1β and TNF-α showed a significant increase in TNBC compared with luminal and Her2 + breast cancers (p < 0.005 by the two-sided Student’s t-test, Fig. 5b). This evidence concerns the gene ERBB2 and breast cancer.
