Male strain A mice were treated with a single i.p. injection of 3-methylcholanthrene (MCA). Four months later, the number of lung tumors was counted. In mice treated three times a week, for 8 weeks, with crude soybean extract containing the Bowman-Birk protease inhibitor (BBI), the number of lung
Dimethylhydrazine (DMH) induces adenocarcinomas of the colon and rectum in rodents; this animal cancer model system is thought to closely resemble human colorectal cancer. An extract of soybeans containing the Bowman-Birk protease inhibitor added to the diet of DMH-treated mice resulted in a
Male strain A/J mice were exposed, 6h a day, 5 days a week for 5 months to a mixture of 89% cigarette sidestream and 11% cigarette mainstream smoke and then allowed to recover for another 4 months in air. The animals were fed Bowman-Birk protease inhibitor concentrate (BBIC) at a concentration of 1%
In this work, we report the effects of a Bowman-Birk protease inhibitor, the Black-Eyed Pea Trypsin/Chymotrypsin Inhibitor - BTCI, purified from Vigna unguiculata seeds, on the MCF-7 breast cancer cells. The treatment of MCF-7 with 200microM BTCI for 72h induced significant reduction of the cell
Model systems in which carcinogenesis by given agents can be prevented or reduced offer a means of gaining insight into the mechanism(s) of action of carcinogens and the feasibility of chemoprevention in humans. In the current study, the ability of the soy-bean derived Bowman-Birk protease (BBI) to
The Bowman-Birk inhibitor (BBI) is a soybean-derived anticarcinogenic protease inhibitor with anti-inflammatory activity. To assess the possibility of utilizing BBI for alleviating the side effects associated with lung cancer radiation and chemotherapy, we have determined the effects of BBI and a
The conjugate of the Bowman-Birk inhibitor (BBI) with poly(D-lysine) (PDL-ss-BBI) has been suggested as a lung-targeted anti-carcinogenic agent. The authors demonstrate that PDL-ss-BBI, given i.p., reduces the tumor number in the lungs of 3-methylcholanthrene treated mice (61-71% compared to control
The present study was designed to confirm whether the Bowman-Birk inhibitor (BBI) induces an increase in p27 accumulation without S phase kinase-associated protein 2 (skp2) degradation by means of the expression of connexin (Cx) 43 as a gap junctional intercellular communication (GJIC)-dependent
Epidemiological studies suggest that human populations consuming diets rich in protease inhibitors have a reduced incidence of cancer at several sites including the breast. Protease inhibitors, such as the Bowman-Birk inhibitor (BBI) have been shown to be highly effective at suppressing
Lunasin is a naturally-occurring peptide demonstrating chemopreventive, antioxidant and anti-inflammatory properties. To exhibit these activities, orally ingested lunasin needs to survive proteolytic attack of digestive enzymes to reach target tissues in active form/s. Preliminary studies suggested
Proteasome inhibitors have been described as an important target for cancer therapy due to their potential to regulate the ubiquitin-proteasome system in the degradation pathway of cellular proteins. Here, we reported the effects of a Bowman-Birk-type protease inhibitor, the Black-eyed pea
Malignancy is considered to be a particular risk associated with exposure to the types of ionizing radiation encountered during extended space flight. In the present study, two dietary preparations were evaluated for their ability to prevent carcinogenesis in CBA mice exposed to different forms of
Malignant mesothelioma (MM) is an aggressive cancer with no effective treatment options. Enforced expression of the gap junction (GJ) component connexin 43 (Cx43) increases the sensitivity of MM cells to cisplatin. Bowman-Birk protease inhibitor (BBI) induces the restoration of Cx43 in several types
Colorectal cancer (CRC) is one of the most common types of cancer, especially in Western countries, and its incidence rate is increasing every year. In this study, for the first time Vigna unguiculata L. Walp. (cowpea) water boiled seed extracts were found to reduce the viability of different
Protease inhibitors play a protective role against pathogenic microorganisms and herbivorous insects. The two predominant protease inhibitors of soybean seeds are the Kunitz trypsin inhibitor (KTI) and Bowman-Birk protease inhibitor (BBI). In this study, we report that soybean seeds incubated in
