Abstract:
The relationship has become clear between the expression of chemokine/chemokine receptors on cancer cells and the invasion, metastasis and peritoneal dissemination. Many cancer cells express chemokine receptors which are not expressed on the surface of normal tissues. Recently, it has been reported that overexpression of CXCR4/CXCL12 is related with metastasis to lung, liver, lymph nodes and bone marrow, while the overexpression of CCR7/CCL21 is mainly related with lymph node metastasis. We performed a comparative analysis of differential gene expressions related to chemokines/chemokine receptors, and cytokines in established gastric cancer cell lines by cDNA microarray. Upregulated chemokine genes were CCL21, CCL5, CXCL14, CCL2, CXCL1, CXCL8, CXCL7 and CXCL12, which the downregulated chemokines genes were MIP-1alpha and TECK. The upregulated gene of chemokine receptors was CCR-6. In the cancer microenvironment, cancer cells readily formed edematous and inflammatory conditions, easily metastasizing to other organs with the suppression of dendritic cells. The chemokines/chemokine receptors will hopefully become the new targets for cancer therapies for the regulation of metastasis.
