ICAM1 and neoplasm: Gene set enrichment analysis of TCGA data revealed that patients with TNBC clustered by high (top quartile) average expression of BTN2A1, BTN3A1, Fas, MICB, and ICAM-1 exhibited higher expression of BCSC genes and gene signatures associated to immune response, inflammation, IFNγ and IFNα responses, cytokine and chemokine signaling and immune-mediated cytotoxicity (Supplementary Fig. S7) suggesting a favorable tumor immune microenvironment.
