Based on bulk RNA data from the TCGA cohort, the highest levels of wild-type CYSLTR2 expression were observed in tumours with an inflammatory phenotype as shown by their immune gene expression signature (high expression of CD14, CD163 [monocytes/macrophages] and CD3D, CD8A [T cells]) (Fig. 4a). The gene discussed is CYSLTR2; the disease is neoplasm.
