The induction of 8-hydroxy-2'-deoxyguanosine (8-OHdG), an index of oxidative DNA modification, was investigated in CHO-K1 cells exposed to phenyl-hydroquinone (PHQ), a major metabolite of ortho-phenylphenol (OPP), an antimicrobial. Addition of PHQ at a concentration of 50 microM to CHO cell

Ortho-phenylphenol (OPP) and its sodium salt (SOPP) are commercial products that have wide human exposure and have been shown in several studies to be rodent carcinogens. Genetic toxicology data were assessed in an attempt to understand the carcinogenic mode of
The effects of o-phenylphenol (OPP) and its metabolite, phenylhydroquinone (PHQ) on the skin of JY-4 black guinea-pigs were studied. Topical application of 1 or 5% PHQ on the black skin of the back caused marked depigmentation and hypopigmentation of the
Recently, we have shown that phenyl hydroquinone, a hepatic metabolite of the Ames test-negative carcinogen o-phenylphenol, efficiently induced aneuploidy in Saccharomyces cerevisiae. We further found that phenyl hydroquinone arrested the cell cycle at G(1) and G(2)/M. In this study, we
ortho-Phenylphenol (OPP) and its sodium salt, which are used as fungicides and antibacterial agents, have been found to cause carcinomas in the urinary tract of rats. To clarify the carcinogenic mechanism of OPP, we compared the DNA damage inducing ability
