Increased CXCL8 expression is negatively correlated with the overall survival of patients with ER-negative breast cancer
Background: C-X-C motif chemokine ligand 8 (CXCL8) is a multi-functional chemokine and has important roles during tumor formation and development. It was previously reported that increased CXCL8 protein levels occurred in certain patients. Materials and Methods: In the present study, we examined levels of CXCL8 mRNA in breast cancer tissues and analyzed its levels in correlation to patients' clini
