To investigate the potential clinical role of chemokine CXCL14 in colorectal cancer, immunohistochemistry staining was performed on 265 colorectal cancer specimens and 129 matched adjacent normal colorectal mucosa specimens with an antibody to CXCL14, the specificity of which we first confirmed (Additional file 1: Figure S1A). The gene discussed is CXCL14; the disease is colorectal cancer.
