EPOR and bladder transitional cell carcinoma: The correlation analysis of EPOR expression with chemokines (Figure 7C) showed that EPOR expression correlated with CXCL2–3, CXCL13, and CCL17/19/22 in CESC, CCL15 in BLCA, CXCL14 in COAD, CXCL2/5 in ESCA, CXCL16 in KIRC, CCL15 in KIRP,and CX3CL1 and CXCL12 in PCPG, and CCL24 in TGCT showed a strong correlation in expression (|r| ≥ 0.3, p < 0.001).
