CCL15 and bladder transitional cell carcinoma: Among the 41 chemokines we studied, 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, CX3CL1 and CXCL12 in PCPG, and CCL24 in TGCT, and the correlation was strong (|r| ≥ 0.3, p < 0.001).
