Within the liver acinus the majority of genes are expressed in an ascending or descending gradient from the portal to the central vein. The regulatory factors involved in this spatial pattern of gene expression are still poorly understood. Many liver

The expression and induction of the cytochrome P450 2B1/2 isoenzyme is heterogeneous, exhibiting a regional pattern in the intact liver and a varied response to phenobarbital in isolated cultured hepatocytes. We report that P450 2B1/2 immunostaining

Gut-derived endotoxins (lipopolysaccharide, LPS) are believed to contribute to alcohol-induced liver disease (ALD) by stimulating Kupffer cells, the resident liver macrophages, to release proinflammatory cytokines. This activation is largely mediated

The aryl hydrocarbon receptor (AHR) is a transcriptional activator of genes encoding a group of drug-metabolizing enzymes, including cytochrome P450 1A1 (CYP1A1), glutathione S-transferase, tumor-associated aldehyde dehydrogenase and quinone reductas

Regional differences in vulnerability to xenobiotic liver damage may relate to the distribution of the detoxication capacity of the glutathione S-transferases (GST). HPLC analysis of cell lysates obtained by digitonin infusion from either the peripor

The effect of hypophysectomy and subsequent infusion of growth hormone (GH) or injections of triiodothyronine (T3) on the acinar expression pattern of four homonally regulated P450 isozymes was studied to elucidate the involvement of pituitary depend

Most cytochrome P-450 enzymes are expressed characteristically in a zonated pattern in the liver. The factors responsible for this heterogenous expression are largely unknown. Here we report how growth hormone and tri-iodothyronine regulate the stero

The CYP2B1/2 gene pair is an example of many liver genes that exhibit a characteristic zonated expression pattern in the liver. The factors governing this zonation are poorly understood. We observed that after hypophysectomy the expression of CYP2B1/
