The purpose of our research is to understand the biochemical basis for dietary enhancement of phorbol ester induced tumor promotion in mice fed high-fat (HF) diet, and the inhibition of promotion in mice fed diets restricted in energy from fat and carbohydrate (ER). The present study assessed the
An earlier study indicated that increased levels of corn oil in the diet resulted in decreased tumor yield after promotion by the phorbol ester 12-O-tetradecanoylphorbol-13-acetate in Sencar mouse epidermis (J Leyton, ML Lee, M Locniskar, MA Belury, TJ Slaga, et al. Cancer Res 51, 907-915, 1991). In
Because arachidonic acid-derived eicosanoids are potent modulators of hyperproliferation and inflammation during skin tumor promotion with the phorbol ester, 12-0-tetradecanoylphorbol-13-acetate (TPA) (17, 18), it was hypothesized that dietary modification of epidermal fatty acids might modulate
Laboratory animal models and clinical studies suggest that dietary n-3 fatty acids are beneficial in diseases with an inflammatory component such as rheumatoid arthritis or psoriasis. In the present study we investigated the effect of purified docosahexaenoic acid (DHA) and eicosapentaenoic acid
Based on the biological activity of arachidonic acid metabolites, we hypothesized that alterations in the consumption of linoleic acid, the precursor to arachidonic acid, would result in a modification in tumor development when fed during the tumor promotion stage of the mouse skin
Numerous studies suggest that tributyltin (TBT) is a potent immunotoxicant in nontarget organisms with lymphoid atrophy being a hallmark response. Two of the most common formulations of TBT are bis (tri-n-butyl)-tin oxide (TBTO) and tri-n-butyl-tin chloride (TBTCl). Most of studies investigating
