RNAseq profiling of mammary carcinomas from WapCreC;Brca1;p53 and littermate WapCreC;Rank;Brca1;p53 females showed differences in their molecular signatures (Supplementary information, Figure S8A and S8B; all primary data have been deposited to Gene Expression Omnibus reference GSE71362); hierarchical clustering of the Spearman's correlation showed similarity of our mouse tumors to previously defined basal-like mammary cancer20 (Supplementary information, Figure S8C). This evidence concerns the gene BRCA1 and breast carcinoma.
