BACKGROUND: After several decades of commercial use, the flame-retardant chemicals polybrominated diphenyl ethers (PBDEs) and their metabolites are pervasive environmental contaminants and are detected in the human body. Decabrominated diphenyl ether (decaBDE) is currently the only PBDE in production in the United States. OBJECTIVES: Little is known about the health effects of decaBDE. In the present study we examined the effects of neonatal decaBDE exposure on behavior in mice at two ages. METHODS: Neonatal male and female C57BL6/J mice were exposed to a daily oral dose of 0, 6, or 20 mg/kg decaBDE from postnatal days 2 through 15. Two …

Hexavalent chromium (Cr(VI)), a commonly used industrial metal, is a well known human lung carcinogen. Epidemiology and animal studies suggest that the particulate Cr(VI) compounds, specifically the water insoluble compounds, are the more potent carcinogens, however, the carcinogenic mechanism remains unknown. Here we summarize recent Cr(VI)-induced human tumour, in vivo, cell culture and in vitro studies and put the data into context with three major paradigms of carcinogenesis: multistage carcinogenesis, genomic instability, and epigenetic modifications. Based on these studies, we propose a mechanism for chromate carcinogenesis that is primarily driven by the genomic instability paradigm.

Background: Osteopontin (OPN) is associated with human cancers, and circulating blood OPN may have diagnostic or prognostic value in clinical oncology. Methods: To evaluate OPN as a cancer biomarker, we generated and characterized five novel mouse monoclonal antibodies against the human full-length OPN (fl-OPN). Epitopes recognized by four antibodies (2C5, 2F10, 2H9, and 2E11) map to N-terminal OPN (aa1-166); one (1F11) maps to C-terminal OPN (aa167-314). These antibodies recognize recombinant and native OPN by ELISA and immunoblot, cross reacting with human and mouse OPN. Two of these novel antibodies ( 2F10 and 1F11) were used to develop a quantitative enzyme …
