The Esophageal cancer-related gene-4 (Ecrg4) is a candidate tumor suppressor gene whose secreted protein product has been implicated in the development and progression of epithelial cancers, neuroprogenitor cell activation after central nervous system injury, cell senescence in neurodegeneration, and the survival of hematopoietic stem cells. Here, we investigated the temporal and spatial localization of Ecrg4 expression in healthy and injured mouse skin, and evaluated the biological activity of Ecrg4 using viral-mediated gene delivery in cutaneous wound healing models. Using in situ hybridization and immunohistochemistry, we found both Ecrg4 mRNA and its protein product localized to the epidermis, dermis, and hair follicles of healthy mouse skin. Upon cutaneous injury, Ecrg4 redistributed to the wound margins where gene microarray and quantitative RT-PCR showed an increased gene expression 5-10 days post-injury as a late phase injury response gene. Ecrg4 over-expression inhibited the directional migration of fibroblasts in modified Boyden chambers in vitro, but had no effect on rates of fibroblast proliferation. Ecrg4 over-expression in vivo at the wound margins delayed the rate of wound closure at 1 and 2 days after full-thickness punch injury. These findings point to the candidate tumor suppressor gene Ecrg4 as a novel, biologically active, constituent of skin and skin injury. The possibility that Ecrg4 serves as a wound termination factor during wound resolution is discussed.
