Heterogeneous subtype defined by TNBC-Specific SEs. (a) NMF analysis of TNBC-specific SE H3K27ac signals in TNBC cell lines and NMF analysis of TNBC samples based on the expression of the TNBC-specific SE target genes. (b) Enrichment analysis of signature genes from different NMF subtypes based on TNBC-specific SE H3K27ac signals or target genes. The enrichment analysis results were categorized into different functional groups. (c) Workflow for extracting TNBC tumor cells from scRNA-Seq datasets. (d) NMF analysis of TNBC tumor cells based on the expression of the TNBC-specific SE target genes. (e) Enrichment analysis of signature genes from different NMF subtypes based on TNBC-specific SE target genes in TNBC tumor cells. (f) Dataset sources, lesion locations, SCSA functional subtypes, and different NMF subtypes of TNBC tumor cells.
