Background/Aims: The effects of Trichostatin A (TSA), a drug candidate for cancer therapy, on proliferation and survival of primary hepatocytes, the major site of xenobiotic biotransformation and primary target of drug-induced toxicity, were investigated.Methods: DNA replication was measured using [methyl- 3 H]-thymidine incorporation. Cell cycle markers were analyzed by Western and Northern...
In this study, we investigated the combined effects of EGF and collagen I gel on the phenotype of cultured rat hepatocytes and we focussed our investigations on the regulation of xenobiotic-mediated induction of CYP, cell cycle progression and activation of capases 8 and 3. We found that EGF, added to basal culture medium or phenobarbital (3.2 mM) containing medium, provoked a moderate decrease of...
