Fragile sites are nonstaining gaps in chromosomes induced by specific tissue culture conditions. They vary both in population frequency and in the culture conditions required for induction. Folate-sensitive fragile sites are due to expansion of p(CCG)n trinucleotide repeats; however, the relationship between sequence composition and the chemistry of… (More)
A panel of 54 mouse/human somatic cell hybrids, each possessing various portions of chromosome 16, was constructed; 46 were constructed from naturally occurring rearrangements of this chromosome, which were ascertained in clinical cytogenetics laboratories, and a further 8 from rearrangements spontaneously arising during tissue culture. By mapping 235 DNA… (More)
A novel microsatellite marker was found within 48.5 kb of the Fas gene. The observed heterozygosity in 160 healthy unrelated controls was 0.78. There was no evidence of linkage to type I diabetes mellitus in 120 diabetic children using the transmission disequilibrium test.
Peroxisome proliferator-activated receptor gamma (PPAR-gamma) activation in adipose tissue is known to regulate genes involved in adipocyte differentiation and lipid metabolism. However, the role of PPAR-gamma in muscle remains unclear. To examine the potential regulation of genes by PPAR-gamma in human skeletal muscle, we used semiquantitative RT-PCR to… (More)
OBJECTIVE To investigate whether skeletal muscle gene expression of calpain 3 is related to obesity and insulin resistance. DESIGN Cross-sectional studies in 27 non-diabetic human subjects and in Psammomys obesus, a polygenic animal model of obesity and type 2 diabetes. MEASUREMENTS Expression of CAPN3 in skeletal muscle was measured using Taqman… (More)
We have recently described a human receptor tyrosine kinase (hek) that is expressed by some pre-B and thymic T cell lines, but is not detectable on normal adult human tissues. Gene cloning studies established that hek is a new member of the EPH family of receptor tyrosine kinases. The expression of hek may normally be developmentally regulated and… (More)
The gene encoding the human transketolase enzyme (TKT) was localized by fluorescence in situ hybridization to normal and FRA3B human chromosomes. Southern blot analysis of a series of human x mouse and human x hamster hybrid cell lines confirmed this localisation. TKT maps to 3p14 and distal to FRA3B, localizing TKT to 3p14.3.
The cloning of the murine obese (ob) gene and its human homologue has recently been reported. Mutations in the mouse ob gene result in hereditary obesity; however, the role of variations of OB in the regulation of bodyweight in humans has yet to be determined. The contribution of putative genetic variations in the human OB gene to total and regional fat… (More)
Distribution as well as amount of fat has health implications; central abdominal fat seems to be the major contributor to insulin resistance and risk of diabetes, hypertension and cardiovascular disease. Physical activity and diet affect overall adiposity; moreover, exercise specifically reduces visceral fat. The sexes differ in fat distribution; in… (More)
