We studied the ability of a soybean extract containing the Bowman-Birk protease inhibitor (BBI), referred to as BBI concentrate (BBIC), purified BBI (PBBI), and the chymotrypsin inhibitor from potatoes to suppress oral carcinogenesis in hamsters induced by 7,12-dimethyl-benz[a]anthracene (DMBA). Application of 1% solutions of BBIC and PBBI five times per(More)
Soybeans are known to contain certain proteins that are allergenic; therefore the anticarcinogenic Bowman-Birk protease inhibitor (BBI), an 8-kDa protein isolated from soybeans, could be capable of generating an immune response that would contraindicate its use as a cancer chemopreventive agent. In the present investigation, the stimulation of antibody(More)
In this study, the distribution of the soybean-derived Bowman Birk inhibitor (BBI) in mice was examined. Mice received [125I]BBI by oral gavage and three hours later, the mice were sacrificed, the organs of interest were carefully removed and the distribution of the inhibitor was determined. The bulk of labeled BBI was present in the luminal contents of the(More)
Previous studies have demonstrated that the soybean-derived Bowman-Birk protease inhibitor (BBI) is effective as a cancer chemopreventive agent in several animal model systems. Proteases represent a key component of several aspects of immune function; therefore the immune system is a primary target for potential toxicity. The present investigation examines(More)
The influence of dietary lipids on immune function has come under serious study only within the past two decades. It is clear from whole-animal studies that obesity and consumption of diets high in fat, particularly unsaturated fat, depress immunocompetence and enhance risk for serious infectious disease and cancer. In vitro systems, cell cultures and the(More)
In these studies, we performed experiments designed to elucidate the role that arachidonic acid metabolism plays in oncogenic transformation in vitro. The levels of TxB2 and 6-keto-PGF1 alpha were elevated in cells treated with X-rays. A significant increase in the levels of these eicosanoids was observed following irradiation. Treatment of cells with the(More)
