NAD(P)H:quinone oxidoreductase (Nqo1)-mediated detoxification of quinones plays a critical role in cancer prevention. Metals alter the carcinogenicity of AhR ligands, such as TCDD, by modulating the induction of Nqo1, but the mechanism(s) remain unresolved. To decipher the molecular mechanisms involved

The effect of chlorophyllin on micronucleated polychromatic erythrocytes (MN-PCE) induction by chromium trioxide (CrO(3)) exposure in peripheral blood of mice was studied. Animals were treated with a single intraperitoneal dose of chlorophyllin (CHL) (20mg/kg), CrO(3) (20mg/kg), and CHL (20mg/kg) 4h

Streptococcus thermophilus strains grown on skimmed milk produced a viscosifying, exocellular, and water-soluble polysaccharide which contains D-glucose, D-galactose, and N-acetyl-D-galactosamine in the ratio of 1:2:1. Methylation analysis identified the glycosidic linkages in the tetrasaccharidic repeating-unit, and Smith degradation and nitrous
