We inactivated the mouse metallothionein (MT)-I and MT-II genes in embryonic stem cells and generated mice homozygous for these mutant alleles. These mice were viable and reproduced normally when reared under normal laboratory conditions. They were, however, more susceptible to hepatic poisoning by cadmium. This proves that these widely expressed MTs are(More)
A new member of the metallothionein (MT) gene family was discovered that lies about 20 kb 5' of the MT-III gene in both mouse and human. The MT-IV proteins are highly conserved in both species and have a glutamate insertion at position 5 relative to the classical MT-I and MT-II proteins. Murine MT-IV mRNA appears to be expressed exclusively in stratified(More)
Glyburide's pharmacokinetics (PK) and pharmacodynamics have not been studied in women with gestational diabetes mellitus (GDM). The objective of this study was to assess steady-state PK of glyburide, as well as insulin sensitivity, beta-cell responsivity, and overall disposition indices after a mixed-meal tolerance test (MMTT) in women with GDM (n = 40),(More)
MT-III, a brain-specific member of the metallothionein gene family, binds zinc and may facilitate the storage of zinc in neurons. The distribution of MT-III mRNA within the adult brain was determined by solution and in situ hybridization and compared to that of MT-I mRNA. MT-III mRNA is particularly abundant within the cerebral cortex, hippocampus,(More)
Metallothionein (MT)-bound zinc accumulates when animals are exposed to excess zinc and is depleted under conditions of zinc deficiency, suggesting that MT serves as a means of sequestering excess zinc as well as a zinc reservoir that can be utilized when zinc is deficient. To examine the importance of MT for these processes, mice with null alleles of both(More)
Wilson disease is an autosomal recessive disorder of hepatic copper metabolism caused by mutations in a gene encoding a copper-transporting P-type ATPase. To elucidate the function of the Wilson protein, wild-type and mutant Wilson cDNAs were expressed in a Menkes copper transporter-deficient mottled fibroblast cell line defective in copper export.(More)
Our objective was to evaluate the pharmacokinetics of metformin during pregnancy. Serial blood and urine samples were collected over one steady-state dosing interval in women treated with metformin during early to late pregnancy (n = 35) and postpartum (n = 16). Maternal and umbilical cord blood samples were obtained at delivery from 12 women. Metformin(More)
Secretory mucins play an important role in the cytoprotection of epithelial surfaces and are used as tumour markers in a variety of cancers. The MUC6 secretory mucin was originally isolated from a gastric cDNA library. The aim was to determine the specific type and location of MUC6 mucin gene expression in a wide range of human adult and fetal epithelial(More)
The metabolism and genotoxicity of the carcinogenic mycotoxin, aflatoxin B1 (AFB), was studied in the lower eukaryotic yeast Saccharomyces cerevisiae. Recombinant strains of yeast were engineered to express human cDNAs for CYP1A1, CYP1A2, and microsomal epoxide hydrolase (mEH). Coexpression of mEH with CYP1A1 or CYP1A2 resulted in significant decreases in(More)
Acetaminophen (APAP) is known to cause centrilobular hepatic necrosis under overdose conditions. This is thought to be mediated via the P450-generated reactive intermediate N-acetyl-p-benzoquinone imine (NAPQI). Initially, NAPQI is detoxified by conjugation with glutathione (GSH), but once GSH is depleted, NAPQI reacts more extensively with hepatic proteins(More)
