The association between FN14 expression and the efficacy of taxanes against breast cancer in vivo was explored by performing experiments with two TNBC breast cancer xenografts obtained from breast cancer patients that expressed (TNBC-EG) or did not express (TNBC-1070) FN14 (Supplementary Figure S1A, right panel and left panel, respectively). This evidence concerns the gene TNFRSF12A and breast cancer.
