CD276, CD44, and VTCN1 were significantly upregulated in IS6 tumours in the TCGA cohort, whereas BTNL2, CD244, CD276, ICOSLG, TMIGD2, TNFRSF18, KIR3DL1, PDCD1, TNFRSF4, TNFRSF8, TNFSF14, TNFSF18, and VTCN1 were overexpressed in IS6 tumours in the GEO cohort. This evidence concerns the gene TNFSF18 and neoplasm.
