Although central to many studies of phenotypic variation and disease susceptibility, characterizing the genetic architecture of complex traits has been unexpectedly difficult. For example, most of the susceptibility genes that contribute to highly heritable conditions such as obesity and type 2 diabetes (T2D) remain to be identified despite intensive study.(More)
The Mouse Metabolic Phenotyping Center (MMPC) Consortium was established to address the need to characterize the growing number of mouse models of metabolic diseases, particularly diabetes and obesity. A goal of the MMPC Consortium is to propose standard methods for assessing metabolic phenotypes in mice. In this article, we discuss issues pertaining to the(More)
Discovery of genes that confer resistance to diseases such as diet-induced obesity could have tremendous therapeutic impact. We previously demonstrated that the C57BL/6J-Chr(A/J)/NaJ panel of chromosome substitution strains (CSSs) is a unique model for studying resistance to diet-induced obesity. In the present study, three replicate CSS surveys showed(More)
Genome sequences are essential tools for comparative and mutational analyses. Here we present the short read sequence of mouse chromosome 17 from the Mus musculus domesticus derived strain A/J, and the Mus musculus castaneus derived strain CAST/Ei. We describe approaches for the accurate identification of nucleotide and structural variation in the genomes(More)
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death worldwide, with approximately 70% of cases resulting from hepatitis B and C viral infections, aflatoxin exposure, chronic alcohol use or genetic liver diseases. The remaining approximately 30% of cases are associated with obesity, type 2 diabetes and related metabolic diseases,(More)
BACKGROUND & AIMS Early growth response-1 (Egr-1), an immediate early gene/zinc-finger transcription factor, is required for maximal stimulation of tumor necrosis factor alpha (TNF-alpha) transcription in response to lipopolysaccharide (LPS). Because chronic ethanol exposure sensitizes macrophages to LPS-stimulated TNF-alpha expression, we have investigated(More)
The plasma membrane protein STRA6 is thought to mediate uptake of retinol from its blood carrier retinol-binding protein (RBP) into cells and to function as a surface receptor that, upon binding of holo-RBP, activates a JAK/STAT cascade. It was suggested that STRA6 signaling underlies insulin resistance induced by elevated serum levels of RBP in obese(More)
CCAAT/enhancer-binding protein (C/EBP) beta and C/EBPalpha are members of the c/ebp gene family and are highly expressed in mammalian liver and adipose tissue. C/EBPalpha is essential for adipogenesis and neonatal gluconeogenesis, as shown by the C/EBPalpha knockout mouse. C/EBPbeta binds to several sequences of the phosphoenolpyruvate carboxykinase (PEPCK)(More)
A single far-upstream enhancer is sufficient to confer hepatocyte-specific, glucocorticoid- and cyclic AMP-inducible periportal expression to the carbamoylphosphate synthetase I (CPS) gene. To identify the mechanism of hormone-dependent activation, the composition and function of the enhancer have been analyzed. DNase I protection and gel mobility shift(More)
We report the characterization of a transcription unit at the second chromosome locus 36B, designated TU-36B which is adjacent to the 3' end of the Drosophila myosin heavy-chain (Mhc) gene. We have isolated and sequenced a complementary DNA clone and the region of genomic DNA which represents this gene. The sequencing studies reveal that this gene contains(More)
