Dietary modifiers of carcinogenesis.
Dietary components express a wide range of activities that can affect carcinogenesis. Naturally occurring substances in foods have been shown in laboratory experiments to serve as dietary antimutagens, either as bioantimutagens or as desmutagens. Dietary desmutagens may function as chemical inactivaters, enzymatic inducers, scavengers, or antioxidants. Dietary components may also act later in t...
متن کاملWnt Lipidation and Modifiers in Intestinal Carcinogenesis and Cancer
The wingless (Wnt) signaling is suggested as a fundamental hierarchical pathway in regulation of proliferation and differentiation of cells. The Wnt ligands are small proteins of about 40 kDa essentially for regulation and initiation of the Wnt activity. They are secreted proteins requiring acylation for activity in the Wnt signaling cascade and for functional interactivity with transmembrane p...
متن کاملInhibition of Carcinogenesis by Minor Dietary Constituents1
A major foundation of the field of cancer chemoprevention has resided in an impressive number of animal studies showing that cancer can be prevented by a variety of chemical compounds. In the search for increas ingly effective inhibitors, both synthetic and naturally occurring com pounds are being investigated. One group of naturally occurring com pounds of particular interest consists of minor...
متن کاملPromotion of intestinal carcinogenesis by dietary methionine.
The metabolism of the polyamines spermidine and spermine is known to be enhanced in rapidly proliferating cells. Methionine is a precursor of the aminopropyl moieties of these amines. Therefore, it was of interest to study the effects of a methionine supplemented diet on polyamine metabolism and preneoplastic changes occurring in the intestinal tract of rats treated with the chemical carcinogen...
متن کاملModulation of carcinogenesis by dietary factors
The purpose of this report is to present recent data on two modulating factors of carcinogenesis that are found in Western-type diets: a beef-derived mutagenesis modulator that has been shown to inhibit the initiation of epidermal carcinogenesis in mice, and the possible role of net energy rather than dietary fat per se in the enhancement of rat mammary carcinogenesis.
