Second, tumor subsets enriched for microenvironment features, including hypoxia markers (e.g., Slc2a1, Pdk1, Car9), extracellular matrix (ECM) genes (e.g., Matn2, Fn1, Dcn, Col6a1), vasculature (e.g., Cdh5, Pecam1, Vwf), and interferon response genes (e.g., Rsad2, Ifit3, Gbp3, Cxcl10, Cd274). The gene discussed is IFIT3; the disease is neoplasm.
