In further support of a direct tumor suppressive (rather than immune-mediated) effect of chemerin, H295R cells with stable expression of human chemerin had decreased colony formation and invasion in in vitro assays and formed smaller tumors when xenografted into the flanks immunodeficient T-cell deficient athymic nude and T, B, and NK-cell deficient and macrophage and dendritic cell-impaired NOD Scid γ mice. Here, RARRES2 is linked to neoplasm.
