NMUR1 and cancer: Initial investigations revealed a pronounced positive correlation between NMUR1 and several immune subtypes (C1: wound healing; C2: IFN-gamma dominant; C3: inflammatory; C4: lymphocyte depleted; C5: immunologically quiet; C6: TGF-β dominant) in pan-cancer contexts, including BLCA (p = 1.32e-03), BRCA (p = 8.38e-09), COAD (p = 2.81e-02), ESCA (p = 2.54e-02), KIRC (p = 1.9e-11), KIRP (p = 1.27e-04), LIHC (p = 2.12e-10), LUAD (p = 2.29e-16), LUSC (p = 1.13e-06), and PAAD (p = 5.39e-06) (Figures 3A and S3).
