When we analyzed the expression of the transcripts of BRCA1 and TP53 in different breast cancer groups, in the patient data taken from the TCGA database, we observed a significantly compromised expression of both the transcripts in the TNBC group, but we could not identify the variation in BRCA1 and TP53 expression within different patients of the TNBC group (n = 109) (Supplementary Figure S1A). This evidence concerns the gene TP53 and breast cancer.
