Abstract

Visfatin has recently been established as a novel adipokine that is predominantly expressed in subcutaneous and visceral fat. Only few studies have investigated the effect of visfatin on prostate, breast, ovarian cancer as well as on astrocytoma cell biology. There have been no previous studies on antioxidative enzyme activities, proliferation processes or levels of DNA damage in malignant melanoma cells in response to visfatin stimulation. Here, we report that visfatin increases activity of selected antioxidative enzymes (SOD, CAT, GSH-Px) in culture supernatants of Me45 human malignant melanoma cells. Our findings suggest that visfatin triggers a redox adaptation response, leading to an upregulation of antioxidant capacity along with decreased levels of the lipid peroxidation process in Me45 melanoma cells. Moreover, visfatin led to a significantly increased proliferation rate in the study using the [3H]thymidine incorporation method. Unlike insulin, visfatin-induced melanoma cell proliferation is not mediated by an insulin receptor. Better understanding of the role of visfatin in melanoma redox states may provide sound insight into the association between obesity-related fat adipokines and the antioxidant defense system in vitro in melanoma progression.
