Two classical mouse hair coat mutations, Rex (Re) and Rex wavy coat (Re wc ), are linked to the type I inner root sheath (IRS) keratin genes of chromosome 11. An N-ethyl-N-nitrosourea-induced mutation, M100573, also maps close to the type I IRS keratin genes. In this study, we demonstrate that Re and M100573 mice bear mutations in the type I IRS gene Krt25; Re wc mice bear an additional...
Alcoholism is a heritable disease that afflicts about 8% of the adult population. Its development and symptoms, such as craving, loss of control, physical dependence, and tolerance, have been linked to changes in mesolimbic, mesocortical neurotransmitter systems utilizing biogenic amines, GABA, and glutamate. Identification of genes predisposing to alcoholism, or to alcohol-related behaviors in animal...
NPM1 gene mutation evaluated on a population basis is a valuable and realistic tool to reflect the pathophysiological relevance of cancer. In a comparison of the NPM1 cDNA of human bladder cancer with its consensus sequence, we have found that a higher NPM1 sequence identity in a population is consistent with poor tumor differentiation, advanced tumor stage, and likelihood of recurrence. These data...
In this paper we describe a method that uses the nearly covalent strength biotin–streptavidin interaction to attach a paramagnetic bead of micrometer size to a DNA molecule of nanometer size, scaling up the spatial size of a query DNA strand by a factor of 1000, making it visible to the human eye. The use of magnetic principles enables rapid binding and washing of detector beads, facilitating a readout...
The coevolution of ticks and the pathogens that they transmit has ensured their mutual survival. In these studies, we used a functional genomics approach to characterize tick genes regulated in response to Anaplasma marginale infection. Differentially regulated genes/proteins were identified by suppression-subtractive hybridization and differential in-gel electrophoresis analyses of cultured IDE8...
Comparative genometrics of microorganisms is a relatively new area, in which genome properties are translated into numerical indexes. Such indexes can be used for a comprehensive and comparative analysis of microbial genomes, contributing to the understanding of their evolution. This work presents a new method for quantitative determination of gene strand bias in prokaryotic chromosomes, in which...
The mechanisms by which trisomy 21 leads to the characteristic Down syndrome (DS) phenotype are unclear. We used whole genome microarrays to characterize for the first time the transcriptome of human adult brain tissue (dorsolateral prefrontal cortex) from seven DS subjects and eight controls. These data were coanalyzed with a publicly available dataset from fetal DS tissue and functional profiling...
The AU-rich element (ARE) is a stability determinant found in the 3′ UTR of a number of short-lived mRNAs. The best characterized ARE is the Shaw–Kamen (SK) box or AUUUA motif. Previously, a fungal metabolite, radicicol analog A (RAA), was shown to destabilize SK box-containing mRNAs based on 16 mRNAs examined [T. Kastelic et al., Cytokine 8 (1996) 751–761]. Using serial analysis of gene expression...
Inborn errors of mitochondrial β-oxidation cause ectopic fat accumulation, particularly in the liver. Fatty liver is associated with insulin resistance and predisposes to hepatic fibrosis. The factors underlying the pathophysiological consequences of hepatic fat accumulation have remained poorly defined. Gene expression profiling in a model of acute fatty liver disease induced by blocking long-chain...
