SCOPE Dysfunction of histone acetyltransferases (HATs) or histone deacetylases (HDACs) involved in histones acetylation has been associated with cancer. Inhibitors of these enzymes are becoming potential targets for new therapies. METHODS AND RESULTS This study reports by Western-Blot analysis, that peptide lunasin is mainly an in vitro inhibitor of(More)
OBJECTIVE The purpose of this study is to investigate the effects of vitamin E supplementation on the autoimmune disease course in MRL/lymphoproliferative mice. METHODS Three-month-old MRL/lymphoproliferative lpr female mice were fed an AIN-76 diet containing 50 mg/kg (control), 250 mg/kg (E5), 375 mg/kg (E7.5), or 500 mg/kg (E10) all-rac-alpha-tocopheryl(More)
BACKGROUND The lower incidence of breast cancer among Asian women compared with Western countries has been partly attributed to soy in the Asian diet, leading to efforts to identify the bioactive components that are responsible. Soy Bowman Birk Inhibitor Concentrate (BBIC) is a known cancer preventive agent now in human clinical trials. (More)
Oxidative stress and inflammation are two of the most critical factors implicated in carcinogenesis and other degenerative disorders. We have investigated how lunasin, a known anti-cancer seed peptide, affect these factors. This peptide inhibits linoleic acid oxidation and acts as 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS)(More)
Carcinogenesis is a multistage process derived from a combination of multiple heritable and environmental factors. It has been reported that populations consuming high levels of soybean products have both lower cancer incidence and mortality rates in the western countries. Lunasin is a novel and promising peptide initially discovered in soy and now found in(More)
Lunasin is a novel peptide identified in soybean and other seeds. This study evaluated the anti-tumorigenic effects of lunasin on 7,12-dimethylbenz(a)anthracene (DMBA) and 3-methylcholanthrene-treated (MCA) fibroblast NIH/3T3 cells. Lunasin significantly inhibited cell proliferation and cancerous foci formation in these 2 chemical carcinogens-treated cells.(More)
Carcinogenesis is a multistage process involving a number of molecular pathways sensitive to intervention. Chemoprevention is defined as the use of natural and/or synthetic substances to block, reverse, or retard the process of carcinogenesis. To achieve greater inhibitory effects on cancer cells, combination of two or more chemopreventive agents is(More)
Obesity prevalence is increasing worldwide and is accompanied by low-grade inflammation with macrophage infiltration, which is linked with a poorer breast cancer prognosis. Lunasin is a natural seed peptide with chemopreventive properties and multiple bioactivities. This is the first study to explore the chemopreventive effects of lunasin in the(More)
Breast cancer is one of the most common cancers in women worldwide. The obesity process is normally accompanied by chronic, low-grade inflammation. Infiltration by inflammatory cytokines and immune cells provides a favorable microenvironment for tumor growth, migration, and metastasis. Epidemiological evidence has shown that aspirin is an effective agent(More)
Obesity has become a major threat to public health and is accompanied by chronic low-grade inflammation, which leads to various pathological developments. Lunasin, a natural seed peptide, exhibits several biological activities, such as anti-carcinogenesis, anti-inflammatory, and antioxidant activities. However, the mechanism of action of lunasin in(More)
