Study assigns meaning to regions beyond genes with implications for studies of common diseases Genes make up only a tiny percentage of the human genome. The rest, which has remained measurable but mysterious, may hold vital clues about the genetic origins of disease. Using a new mapping strategy, a collaborative team led by researchers at the Broad Institute of MIT and Harvard, Massachusetts General Hospital (MGH), and MIT has begun to assign meaning to the regions beyond our genes and has...

Dominant model of human adaptation may have played smaller role than thought The most popular model used by geneticists for the last 35 years to detect the footprints of human evolution may overlook more common subtle changes, a new international study finds. Classic selective sweeps, when a beneficial genetic mutation quickly spreads through the human population, are thought to have been the primary driver of human evolution. But a new computational analysis, published in the February 18,...

A study from the 1000 Genomes Project yields data for analyzing structural variants in DNA Advances in DNA sequencing technology have revolutionized biomedical research and taken us another step forward in personalized medicine. Now, scientists led by Brigham and Women's Hospital (BWH), Harvard Medical School (HMS), the Broad Institute, the Wellcome Trust Sanger Institute (WTSI), the University of Washington, and the European Molecular Biology Laboratory, have developed a new framework for...

A large collaborative study has added to the growing list of genetic variants that determine how tall a person will be. The research, published by Cell Press on December 30 in the American Journal of Human Genetics, identifies uncommon and previously unknown variants associated with height and might provide insight into the genetic architecture of other complex traits. Although environmental variables can impact attained adult height, it is clear that height is primarily determined by...

Molecular evidence supports long-suspected historical connection Apricots are important to Turkey, the country where more apricot crops are grown and exported than anywhere in the world. Looking to unlock the mystery of apricots' origins and increase crop production, scientists are studying the genetic relationship between apricot varieties. New research from a team of Hungarian and Turkish scientists has confirmed the genetic link between Turkish and Hungarian apricot cultivars, yielding...

Personalized medicine centers on being able to predict the risk of disease or response to a drug based on a person's genetic makeup. But a study by scientists at Washington University School of Medicine in St. Louis suggests that, for most common diseases, genes alone only tell part of the story. That's because the environment interacts with DNA in ways that are difficult to predict, even in simple organisms like single-celled yeast, their research shows. "The effects of a person's genes...

Since 1871, when Charles Darwin wrote The Descent of Man, it has been widely accepted that "Variability is the necessary basis for the action of selection." Variability is associated with the ability to adapt, which is clearly beneficial at a species level. But there is increasing evidence that genetic variability may also give rise to advantages at the level of the individual. Steve Smith and Franz Suchentrunk at the Research Institute of Wildlife Ecology, University of Veterinary Medicine,...

Scientific risk assessment conducted on introduction of exotic species A potential solution for global energy demands is the use of Poplar, a fast-growing tree with high yields, for biofuels. To get the most out of Poplar plantations, varieties that are the best fit for the conditions"”ones with disease resistance or higher yields, for example"”are desired. But do these plantations of new, non-native (exotic) species impact nearby native populations of Poplar? In particular, is...

In an unprecedented international project, researchers have found multiple genetic mutations that play a role in heart attack or coronary artery disease (CAD) risk. The Coronary ARtery DIsease Genome-wide Replication And Meta-Analysis (CARDIoGRAM) "” published in Circulation: Cardiovascular Genetics, an American Heart Association journal "” consists of data from every published whole-genome study on genetic mutations in heart attack or CAD risk. Researchers are also pooling data...

Sensation seeking"”the urge to do exciting things"”has been linked to dopamine, a chemical that carries messages in your brain. For a new study published in Psychological Science, a journal of the Association for Psychological Science, scientists analyzed genes in the dopamine system and found a group of mutations that help predict whether someone is inclined toward sensation seeking. Sensation seeking has been linked to a range of behavior disorders, such as drug addiction. It...

House Mouse, Mus musculus
2012-05-01 11:42:07

Even in the wild, this rodent is associated with humans by destroying crops and stored food. The house mouse is also known as the fancy mouse, a common pet. It is also a widely used laboratory animal, important for testing in genetics, biology, and medicine. There are three recognized subspecies of the house mouse. These mice thrive in a number of locations including fields, houses, and commercial structures. An adult male house mouse can have a body length of up to 3.9 in, and tail length...
