In addition, our study revealed that MXRA8 expression correlated with the expression of multiple metastasis-associated chemokines (CXCL12, CXCL13, CCL9, CCL21, CXCR4, CXCR5, and CCR7) (31–37), suggesting that MXRA8 may be involved in tumor invasion and metastasis by regulating the secretion of chemokines. The gene discussed is CCL21; the disease is neoplasm.
