  • Genetic breakthrough explains dangerously high blood glucose levels

    ... study originally conducted for diabetes research that looked at over 390,000 different locations – or loci – on the human genome. The study’s first important diabetes results were published in 2007 ...
  • Genetic loci assigned for musical aptitude in Finnish families

    Molecular and statistical genetic studies in 15 Finnish families have shown that there is a substantial genetic component in musical aptitude. Musical aptitude was determined using three tests: a ...
  • Estimation of isolation times in the Drosophila simulans complex

    ... ." New DNA sequence variation data for 17 loci corroborate the prior observation from 13 ... reflect gene flow of the low-recombination loci subsequent to initial isolation, but it might also reflect ...
  • SEX4, starch and phosphorylation

    ... in textbooks. Specifically, mutations at the Starch Excess 4 (SEX4), Maltose Excess 1 (MEX1) and other loci produce plants unable to metabolize starch to a usable form. When we use starch in the ...
  • Also in the June 24 JNCI

    ... , but not with the other three malignancies. "We have shown there are at least five independent loci within this gene desert with different associations with particular cancers," the authors write. " ...
  • Scientists find how neural activity spurs blood flow in the brain

    ... process in the olfactory bulb, which processes odors. "When a mouse encounters a scent, discrete loci in its olfactory bulb are activated, which in turn increases blood flow in those spots," Murthy ...
  • Evolution of fruit size in tomato

    ... are being applied in both well-known and obscure solanaceous species. Conservation of genes and loci across a number of these species suggests that the knowledge gained from these efforts can also be ...
  • The 21st century tomato

    ... chromosomal regions called quantitative trait loci (QTLs), because they produce a range of values ... 1200 metabolic QTLs or quantitative metabolic loci (QMLs) were identified and analyzed. Almost 900 ...
  • Complexity of Crohn's disease revealed as 'gene' count tops 30

    ... require surgery at some point. Previous studies have already identified 11 genes and loci (regions of the genome typically including one or more genes) that increase susceptibility to the disease. ...
  • Plants in the fourth dimension

    ... . The scientists are now also examining the clock genes in other plants and have found quantitative trait loci (QTLs) for these genes in the model crop species Brassica rapa (rapeseed). QTLs are ...
  • A microsatellite-guided insight into the genetic status of the Adi tribe

    ... populations from east and south-east Asia) for genetic diversity based on the autosomal loci, the resultant clustering tree showed some of the Tibeto-Burman tribes clustering with the populations ...
  • Mate selection more biologically determined in some human populations

    ... reported a tendency for humans to prefer MHC-dissimilar mates, encouraging heterozygosity at MHC loci in offspring and resulting in improved immune response. However, other studies, both directly in ...
  • LOH analysis on 4q in sporadic colorectal carcinoma

    ... and the other allele is lost through a number of possible mechanisms, resulting in LOH at multiple loci. LOH is the most common molecular genetic alteration observed in human cancers. A great deal of ...
  • Sexual practice of polygyny skews genetic variability

    ... the X chromosome. The research team measured levels of neutral polymorphism at 40 independent loci on the X chromosome and autosomes in ninety humans representing six populations, including: Biaka ( ...
  • New genes linked to gout

    ... determine who might benefit from medications to prevent the development of gout. "Association of three Genetic Loci with Uric Acid Levels and Gout Risk," is published online in The Lancet September 30 ...
