Quinone Oxidoreductase 1 Expression in Human Primary Melanotic Melanomas of the Skin

quinone oxidoreductase 1 (NQ01; DT-diaphorase; DTD) is a two-electron reducing enzyme which is often over-expressed in cancers and can activate quinones to form cytotoxic species. This over-expression is used as target in the design of novel anti-cancer drugs. DTD is also expressed in normal tissues, but little is known about its “body mapping”. Because of the dearth of information on the cell-specific expression of DTD in pigmentproducing cells of the skin, we analysed its expression in normal and tumoral samples. Twenty skin biopsies of primary malignant melanotic melanomas (ten with vertical invasion, ten with superficial spreading) were analysed by immunohistochemistry.
