BAD and breast carcinoma: Similar to our results shown in the tumour samples, gene expression data from 42 breast cancer cell lines (28 TNBC, 14 non-TNBC) indicated a differential expression of the BAD pathway in TNBC cell lines, with a mean BPGES score of −1.81 ± 0.33 in non-TNBC cells versus a mean BPGES score of .90 ± 0.25 in TNBC cells (unpaired t test, P = 4.22 × 10−7; Fig. 3A,B).
