The objective of this research project is to identify cellular, biochemical, and molecular mechanisms for the adverse developmental neurotoxicity of pesticides.
During the previous cycle of this research project, we conducted studies evaluating three classes of pesticides in both in vitro and in vivo assessments. A final manuscript has resulted from Dr. Xia’s studies comparing the impact of chlorpyrifos (CP) in embryonic and newborn cortical neurons. Her investigations into the proposed mechanisms of toxicity associated with CP and its two major metabolites, chlorpyrifos-oxon (CPO) and 3,5,6-trichloro-2-pyridinol (TCP; the breakdown product of both CP and CP-oxon) were reported recently in a publication (Caughlan, et al., 2004) and are summarized in this progress report. We focused our experiments to address arsenic and methylmercury neurotoxicity and expanded significantly our understanding of the molecular mechanisms of toxicity associated with CP and its two major metabolites in embryonic midbrain cultures.
