Importantly, based on our data for 7 Ba/Sq samples, we were able to identify higher enhancer activity associated with potential key genes in Basal tumour biology, including cell surface receptors (IL7R, OSMR, EGFR, MET) and transcriptional regulators (BNC2, HMGA2, KLF7, NR3C1). This evidence concerns the gene MET and neoplasm.
