The role of CXC chemokine ligand 4/CXC chemokine receptor 3-B in breast cancer progression.

| Abstract |
Chemokines and their receptors participate in the development of cancers by enhancing tumor cell proliferation, angiogenesis, invasion, metastasis and penetration of tumor immune cells. It remains unclear whether CXC chemokine ligand 4 (CXCL4)/CXC chemokine receptor 3-B (CXCR3-B) can be used as an independent molecular marker for establishing prognosis for breast cancer patients. We evaluated CXCL4 and CXCR3-B expression in 114 breast cancer tissues and 30 matched noncancerous tissues using immunohistochemistry and western blot, and determined the correlation between their expression and clinicopathologic findings. We observed that breast cancer tissues express CXCL4 strongly and CXCR3-B weakly compared to noncancerous tissues. Strong CXCL4 expression was detected in 94.7% and weak CXCR3-B expression was detected in 78.9% of the tissues. Therefore, CXCL4/CXCR3-B might play a crucial role in breast cancer progression. We found no significant correlation between CXCL4 and age, tumor stage, tumor grade or TNM stage. CXCR3-B was associated significantly with tumor grade. Moreover, the Chi-square test of association showed that the expression of CXCL4/CXCR3-B might be an independent prognostic marker for breast cancer. Therefore, we suggest that CXCR3-B is an indicator of poor prognosis and may also be a chemotherapeutic target.
