Halobenzenes are ubiquitous environmental contaminants, which are hepatotoxic in both rodents and humans. The molecular mechanism of halobenzene hepatotoxicity was investigated using Quantitative structure-activity relationships (QSAR) and accelerate

A single nucleotide polymorphism in the COMT (catechol-O-methyltransferase) gene that alters the amino acid sequence at codon 108 of S-COMT from val to met (val108met polymorphism) has been associated with a number of diseases and neuropsychiatric di

Freshly prepared human hepatocytes are considered as the 'gold standard' for in vitro testing of drug candidates. However, several disadvantages are associated with the use of this model system. The availability of hepatocytes is often low and conseq

We report here our studies on troglitazone and rosiglitazone cytotoxicity in human hepatocytes isolated from multiple donors to investigate factors responsible for individual differences in sensitivity to the known hepatotoxicity of these antidiabeti

Cryopreserved human hepatocytes were extensively characterized in our laboratory. The post-thaw viability, measured via dye exclusion, ranged from 55 to 83%, for hepatocytes cryopreserved from 17 donors. Post-thaw viability and yield (viable cells pe

Cryopreserved human hepatocytes in suspension were used to estimate in vivo hepatic clearances for six different drugs. In vitro intrinsic clearances were measured on the basis of substrate depletion. The number of different hepatocyte donors require

Cryopreserved human hepatocytes have been used to predict hepatic in-vivo clearance. Physiologically-based direct scaling methods generally underestimate human in-vivo hepatic clearance. Cryopreserved human hepatocytes were incubated in 100% serum an

Rat hepatocytes were cultured initially as spheroids on culture plates and then transferred into a rotating wall vessel (high-aspect ratio vessel [HARV]) for further culturing. Morphological evaluation based on electron microscopy showed that hepatoc

Troglitazone (TGZ) is an orally active antihyperglycemic agent used in the treatment of noninsulin-dependent diabetes mellitus. Several cases of liver failure following TGZ administration led to its withdrawal from the market. The mechanism of toxici
