How species form and what keeps them distinct from each other, even though they can interbreed, is a key question in evolution. Researchers from Taiwan, led by Dr. Jun-Yi Leu, an Assistant Research Fellow from the Institute of Molecular Biology at Academia Sinica, have recently identified genes in three closely-related yeast species that cause sterility, increasing our understanding of how species can remain distinct. The findings will be published next week in the online, open access journal...

Genetic variant detected by genome-wide association found to increase expression of oncogene A genetic variant implicated in several cancers by genome-wide association studies (GWAS) has been found to drive increased expression of a known oncogene in the prostate. The study, published July 13th in Genome Research, showcases a new protocol for studying the activity of cancer-risk variants suggested by GWAS studies. The results also underscore the dramatic consequences of small genetic changes...

Fewer males than females are surviving the negative effects of inbreeding in a reintroduced population of a rare New Zealand bird, reports new research published in Proceedings of the Royal Society B. Studying a population of the endangered New Zealand Hihi, researchers from the Zoological Society of London found that male survival rate was 24 per cent lower than their female siblings during early development, and as chicks. The researchers analysed 98 clutches on Tiritiri Matangi Island, a...

Boston University researchers have discovered a genetic sequence that predicts with more accuracy than ever before whether a person will live to the age of 100 -- even if they have other genes associated with disease. The scientists studied over 1,055 centenarians to develop a system of genetic analysis that predicts with 77-percent accuracy whether a person has a strong chance of "exceptional longevity".  The predictions involve identifying the presence of 150 genetic variants known as...

New study at University of Leicester aims to pave way for treatments New research at the University of Leicester will use the latest genetic techniques to examine DNA from over 20,000 patients with heart disease. The study will help to identify new genes and molecules responsible for Coronary Artery Disease (CAD). This, in turn may help to develop new diagnostic and treatment strategies. The project is being undertaken by postgraduate researcher Paraskevi Christofidou, of the Department of...

Inbred male sperm have been found to fertilize fewer eggs when in competition with non-inbred males according to a new study by the University of East Anglia. Research into the breeding habits of the red flour beetle, published June 15 in Proceedings of the Royal Society B, shows that the reduced fitness of inbred beetles, known as 'inbreeding depression', reveals itself in competitive scenarios. Inbreeding is a potentially important problem in declining species across the world, and...

Three genes that have barely been studied to date have now provided fresh knowledge about patients with suicidal backgrounds. This is the result of a study by a team of Spanish researchers at Mount Sinai Hospital and Columbia University in the City of New York (United States), which found that several mutations are involved. This finding could help to develop future genetic tests to identify predisposition to suicide, without ignoring the importance of social and cultural factors. "There is...

A tool for clinicians as well as geneaologists Understanding the genetic ancestry of mixed populations, such as those found in North America, can not only help to detect their origins but also to understand the genetic basis of complex diseases, a scientist will tell the annual conference of the European Society of Human Genetics today (Saturday June 11). It is the first time that the genomes of individuals of admixed ancestry have been sequenced in such detail, says Dr. Francisco De La Vega...

New studies have found that Jews share a genetic bond with Cypriots and Druze and verifies the Jewish Diaspora maintained a strong DNA continuity despite its long separation from the Middle East, according to scientists on Wednesday. The work is part of a larger exploration into human migration based on groups of tiny differences in genetic codes. "We found evidence that Jewish communities originated in the Near East," said molecular scientist Doron Behar of the Rambam Health Care Campus in...

ASHG publishes follow-up white paper report that explains scientific reasoning and expands on recommendations made in 2008 policy statement Genetic ancestry testing is a practice that has become increasingly popular in the U.S. over the past few years. An estimated half-million Americans will purchase genetic ancestry tests from one of the approximately 40 companies worldwide that currently provide this type of service to consumers. However, increasing public interest in Direct-to-Consumer...

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...
