CXCL16 is an interferon-inducible chemokine of the CXC-subfamily and functions as an adhesion molecule, when membrane bound, and a chemoattractant when soluble. Upregulation of cell associated CXCL16 (cCXCL16) in colorectal cancer is associated with increased tumor infiltrating lymphocytes and good prognosis. ADAM10 and ADAM17 are metalloproteinases responsible for cleaving CXCL16, releasing soluble CXCL16 (sCXCL16) and contributing to proliferation and migration of mesangial cells, in kidney inflammatory disease. We hypothesize that cCXCL16 is a substrate for ADAM10 and ADAM17 cleavage in colorectal cancer, releasing sCXCL16, which mediates cell proliferation. To this end, we first identified CXCL16 in the human colon carcinoma …
