IL2 and bladder transitional cell carcinoma: We then defined marker genes for transcriptional signatures representing resting NK cells (ReNK) (95), IL-2-expanded NK cells (IL2NK), and a signature of PDGF-DD-activated NK cells (SPANK) (96), respectively, and established the transcript abundance of these NK cell phenotypes in TCGA BLCA cohort using CIBERSORT (please see Methods).
