CXCL14 and neoplasm: Also known as BRAK (breast and kidney-expressed chemokine), Cxcl14 expression is relatively high in many normal tissues but lost in various types of malignancies.11,12 Conversely, there are a number of reports demonstrating Cxcl14 overexpression in various tumour microenvironments, and implicating Cxcl14 in invasion and metastasis,13–16 indicating that its role in cancer may be cell-type specific.
