Both IL-8 and CXCL16 have previously been shown to attract monocytes in a tumor microenvironment.7, 8 Chemerin expression at mRNA level has been reported from malignancies such as mesothelioma9 and adrenocortical tumors.10 However, the role of chemerin in tumor biology remains unclear. This evidence concerns the gene RARRES2 and adrenal cortex neoplasm.
