| Research Abstract |
We exposured mouse primary hepatocytes to chemicals that are commonly used in our daily lives like hydroquinone, lawsone. We found that exposure the cells to these chemicals decreased cellular viability in both catalase mutant mice (Cs^b) and the wild-type mice (Cs^a) dose-dependently, in particular, the survival of hepatocytes was lower in Csbwhen compared to that of Cs^a. We also observed that exposure the cells to hydroquinone, a main component of skin-lightening cream, enhanced the cellular expression of cytochrome P450 2E1 mRNA and protein dose-dependently as well as induced apoptosis of the cells.
