Thus, we performed correlation analyses between immune-related genes and NT5E expression level on pan-cancer level, and uncovered that the expression levels of several immunoinhibitors were positively correlated with NT5E expression, including kinase insert domain-containing receptor (KDR), interleukin-10 receptor B (IL10RB) and transforming growth factor-beta receptor 1 (TGFBR1) (Supplementary Figures S1, S2). The gene discussed is KDR; the disease is cancer.
