The melanocortin-3 receptor (MC3R) gene is pleiotropic, influencing body composition, natriuresis, immune function, and entrainment of circadian rhythms to nutrient intake. MC3Rs are expressed in hypothalamic and limbic regions of the brain and in peripheral tissues. To investigate the roles of central MC3Rs, we inserted a "lox-stop-lox" (LoxTB) 5' of the(More)
Brome mosaic virus (BMV) belongs to a "superfamily" of plant and animal positive-strand RNA viruses that share, among other features, three large domains of conserved sequence in nonstructural proteins involved in RNA replication. Two of these domains reside in the 109-kDa BMV 1a protein. To examine the role of 1a, we used biologically active cDNA clones of(More)
We performed genome-wide chemical mutagenesis of C57BL/6J mice using N-ethyl-N-nitrosourea (ENU). Electroretinographic screening of the third generation offspring revealed two G3 individuals from one G1 family with a normal a-wave but lacking the b-wave that we named nob4. The mutation was transmitted with a recessive mode of inheritance and mapped to(More)
Previous studies have shown that the mitochondrial orf224/atp6 gene region is correlated with the Polima (pol) cytoplasmic male sterility (CMS) of Brassica napus. We now extend this correlation by showing that the effects of nuclear fertility restoration on orf224/atp6 transcripts cosegregate with the pol restorer gene Rfp1 in genetic crosses. We also show,(More)
BACKGROUND Elevation of intraocular pressure (IOP) following injection of intravitreal triamcinolone acetonide (IVTA) is an important clinical problem. The etiology of the steroid response is poorly understood, although a genetic determinant has long been suspected. We performed a pharmacogenomic association study with glucocorticoid receptor polymorphisms.(More)
Inhibition of intestinal carboxylesterases may allow modification of the pharmacokinetics/pharmacodynamic profile of existing drugs by altering half-life or toxicity. Since previously identified diarylethane-1,2-dione inhibitors are decidedly hydrophobic, a modified dione scaffold was designed and elaborated into a >300 member library, which was(More)
Brome mosaic virus (BMV) genomic RNA2 encodes the 94-kDa 2a protein, which is one of two BMV nonstructural proteins required for RNA replication and subgenomic mRNA transcription. 2a contains a central polymeraselike region, which has extensive sequence similarity with the Sindbis virus nsP4 and tobacco mosaic virus (TMV) 183-kDa replication proteins, and(More)
The leukocyte NADPH oxidase catalyzes the reduction of oxygen to O(2)(-) at the expense of NADPH. Extensive phosphorylation of the oxidase subunit p47(PHOX) occurs during the activation of the enzyme in intact cells. p47(PHOX) carrying certain serine-to-alanine mutations fails to support NADPH oxidase activity in intact cells, suggesting that the(More)
Wnt proteins and beta-catenin signaling regulate major processes during embryonic development, and we hypothesized that they regulate cranial base synchondrosis development and growth. To address this issue, we analyzed cartilage-specific beta-catenin-deficient mice. Mutant synchondroses lacked typical growth plate zones, and endochondral ossification was(More)
OPRL1 encodes the nociceptin receptor, which has been shown to be involved in alcohol dependence in previous studies. In the present study, we investigated the association between genetic polymorphisms of OPRL1 and alcohol dependence in a Scandinavian population. We genotyped 15 single nucleotide polymorphisms (SNPs) spanning the OPRL1 locus and found that(More)
