| Research Abstract |
Using human nueroblastoma cells, rat cardiomyocyte-derived cells, and rat liver as well as heart, molecular mechanisms of cytotoxicity of several toxicants including metamphetamine, cocaine, and LPS were examined. Major-responsible proteins were determined by the method of proteomics. Involvement of macropinocytosis, myosin gene expression, and active extrusion of mitochondrial proteins were suggested during methamphetamine, cocaine, and LPS exposure, respectively. These results have proved usefulness of the method of proteomics in the field of forensic toxicology.
