TCGA analysis of TNBC and basal-like BC samples showed that pathways associated with CSC biology (integrin and integrin-linked kinase (ILK) signaling [42], Wnt/ß-catenin [43], actin-ARP-WASP [44], Notch signaling [45], BRCA [46] and embryonic stem cells (ES) transcriptional networks) were positively correlated with EP300 expression. This evidence concerns the gene WAS and breast cancer.
