EPOR and uveal melanoma: Moreover, EPOR expression correlated more strongly with CD4 + T cell infiltration in ACC, kidney renal papillary cell carcinoma (KIRP), and rectum adenocarcinoma (READ) (r = 0.357, 0.418, 0.34); EPOR expression correlated more strongly with dendritic cell infiltration in ESCA, LIHC, and uveal melanoma (UVM) (r = 0.323, 0.309, 0.32); and EPOR expression correlated more strongly with macrophage infiltration in READ (r = 0.307).
