The reoccurrence of androgen-dependent prostate cancer after anti-androgen therapy mainly depends on prostate cancer stem-like cells. To reduce the risk, it is important to delete the cancer stem-like cells. Furthermore, to induce differentiation of cancer stem-like cells is critical to abrogate
Understanding molecular recognition on a structural basis is an objective with broad academic and applied significance. In the complexes of serine proteases and their proteinaceous inhibitors, recognition is governed mainly by residue P1 in accord with primary serine protease specificity. The
Bowman-Birk inhibitors (BBIs) are protein molecules containing two inhibitory domains for enzymes similar to trypsin and chymotrypsin. Interest in these inhibitors arose from their properties against the cancer chemically induced by 1,2-dimethylhydrazine (DMH). In this study the effect of two BBI
Leukoplakia in the oral cavity has been used as a putative surrogate marker of head and neck cancer development. A class of chemoprevention compounds, called protease inhibitors, has been shown in vitro and in animal models to effectively suppress premalignant lesions. Bowman-Birk inhibitor (BBI) is
Bowman-Birk inhibitor (BBI) is a soybean-derived anticarcinogenic protease inhibitor that was shown to potentiate the cytotoxicity of cisplatin in our previous studies. To assess the potential of BBI as a sensitizing agent for the chemotherapy of cisplatin-resistant cancers, we evaluated the effects
BACKGROUND
The Bowman-Birk inhibitor (BBI) is a soybean-derived serine protease inhibitor with demonstrated anticarcinogenic activity in both in vitro and in vivo systems.
METHODS
The effects of BBI and BBI Concentrate (BBIC), a soybean concentrate enriched in BBI, on cell growth, invasion, and/or
BACKGROUND
Bowman Birk inhibitor (BBI) is an anticarcinogenic serine protease inhibitor that may inhibit the protease activity of prostate-specific antigen (PSA) and the growth of human prostate cancer xenografts in nude mice.
METHODS
Human prostate cancer xenografts were established by implanting
OBJECTIVE
Cancer chemoprevention is a rapidly evolving approach to reverse or inhibit carcinogenesis, and there is active interest in development of effective chemopreventive agents against head and neck cancers. The retinoids are archetypal chemopreventive agents for oral premalignant lesions. They
The Bowman-Birk inhibitor (BBI), a soybean-derived protease inhibitor with well-characterized ability to inhibit trypsin and chymotrypsin activities, has been shown to be an effective suppressor of carcinogenesis and treated in human phase IIa clinical trial. However, the precise mechanisms by which
Bowman-Birk inhibitor (BBI) is a soybean-derived anticarcinogenic protease inhibitor previously shown to potentiate cisplatin-induced cytoxicity in human lung and ovarian cancer cells. To further assess the potential of BBI as a sensitizing agent for cancer radiotherapy and chemotherapy, we
Amphibian venom-derived peptides have high potential in the field of anticancer drug discovery. We have isolated a novel Bowman-Birk proteinase inhibitor (BBI)-type peptide from the skin secretion of Pelophylax esculentus (PE) named PE-BBI, and evaluated its bio-functions and anti-cancer activity in
We describe our studies to produce an extract of soybeans with anticarcinogenic activity that we believe will be useful as a human cancer chemopreventive agent for several different organs. The anticarcinogenic activity of the extract is thought to be due to chymotrypsin inhibitor activity, which is
Certain protease inhibitors are effective at preventing or suppressing carcinogen-induced transformation in vitro and carcinogenesis in animal model systems. One protease inhibitor, the soybean-derived Bowman-Birk inhibitor (BBI) is particularly effective in suppressing carcinogenesis. BBI is a
The present study was designed to investigate the effects of Bowman-Birk inhibitor concentrate (BBIC) on anti-proliferation, up-regulation of Connexin 43 (Cx43) expression and inhabitation of hepatic metastasis in mice with M5076 ovarian sarcoma. M5076 ovarian sarcomas (1x106 cells/animal) were
A major goal in the development of chemopreventive agents has been to develop markers that reflect the underlying process of carcinogenesis and which are modulatable by the agent under study. An important application of such markers will be to select cohorts that are at elevated risk for cancer
