The contribution of TCE-derived DCA to the induction of hepatocellular carcinoma in the mouse liver bioassay has been a pivotal issue in assessing the risk associated with oral exposure to TCE. The goal of this study was to investigate the biological plausibility of the hypothesis that TCE- derived DCA contributed significantly to TCE-induced mouse liver cancer. A pharmacokinetic analysis for DCA in naive and DCA-pretreated mice has been conducted in ...
