Researchers identify gene involved in dog size

...been selectively bred, allowing us to more readily analyze the genetic causes of particular traits than is possible in humans,?said the study’s senior author Elaine A. Ostrander, Ph.D., chief of NHGRI’s Cancer Genetics Branch. “Nearly all of what we learn from studying body structure, behavior and disease su...

Beyond the DNA: Chemical signatures reveal genetic switches in the genome

...duate Program. "We used genome-scale approaches to analyze the chromatin architecture in human cells and discovered distinct signatures of modified histones that correspond to known promoters and enhancers. These findings enabled us to generate computational algorithms that identified hundreds of novel genom...

Sandia researchers take new approach to studying how cells respond to pathogens

NIAID expands capability for influenza research and surveillance

...s and are transmitted between different hosts, and analyze human immune responses to influenza vaccination and infection. The researchers will examine how human genes might be silenced to decrease or eliminate flu infections; identify new targets for antiviral medicines; and evaluate flu transmission between...

Danish researches solve virus puzzle

...ertise and the technique to be able to measure and analyze the physical processes.?says Lene Oddershede, physicist at the Niels Bohr Institute, University of Copenhagen. This interdisciplinary work between physics and biology has been very fruitful and will be published April 3rd in the prestigious scientifi...

Hives ferment a yeasty brew, attract beetle pest

...ers used a gas-chromatagraph-electroantennogram to analyze the chemical sensitively of the insects' antennae. They report in a recent online issue of the Proceedings of the National Academy of Sciences that the beetles could detect the equivalent of 2 nanograms of IPA at the entrance to an undisturbed honeyb...

DOE JGI sets 'gold standard' for metagenomic data analysis

...ome Biology Program. "We are now exploring ways to analyze metagenomic data to enable accurate classification of sequence fragments into their corresponding species populations. The goal is to reconstruct metabolic pathways by comparing with reference isolate genomes, so that we can model ecosystem dynamics...

New technique will produce a better chromosome map

How to steer a moving cell

...front and back of the chemotactic cell in order to analyze the components of its protein network. The cell fractionation equipment developed in Klemke’s lab is the first method to enable researchers to study the entire network of signaling proteins. "To find out what goes wrong during metastasis, we need...

Exploring the role of invasive organisms, Laura Meyerson (University of Rhode Island, US) and Harold Mooney (S...

Turn-ons and turn-offs for neurons

.... The Tet-regulated gene expression can be used to analyze involvement of genes for example in cognition in the mouse, as was shown in key studies from 1996. But in spite of the published success, others scientists report some difficulties: in some experiments the full reactivation of Tet-regulated genes fai...

Exploring the dark matter of the genome

...rsity. "We used a pipeline of computer programs to analyze the raw sequence data, in search of genes. We identified patterns of codons that might indicate a gene splice-site or a promoter, for example. We mapped experimentally derived evidence of messenger RNAs back to the matching heterochromatin sequence. ...

New findings challenge established views on human genome

... to conduct multiple, diverse experiments and then analyze them using multiple computational methods,” said Elise A. Feingold, Ph.D., program director for ENCODE in NHGRI’s Division of Extramural Research, which provided most of the funding for the pilot project....

Blood test may help signal tumor's remission, return in throat cancer patients
