Human Genome
In research published today by Nature, an international team describes the finest map of changes to the structure of human genomes and a resource they have developed for researchers worldwide to look at the role of these changes in human disease. They also identify 75 'jumping genes' - regions of our genome that can be found in more than one location in some individuals.
In one of the first studies of its kind, an international team of researchers has uncovered a single-letter change in the genetic code that is associated with autism. The finding, published in the October 8 issue of the journal Nature, implicates a neuronal gene not previously tied to the disorder and more broadly, underscores a role for common DNA variation.
Blacksburg, Va. -- Theresa M. Reineke, associate professor of chemistry in the College of Science, and colleagues in her lab at Virginia Tech and at the University of Cincinnati have developed a new molecule that can travel into cells, deliver genetic cargo, and packs a beacon so scientists can follow its movements in living systems.
PHILADELPHIA -- Social environment can play an important role in the biology of disease, including breast cancer, and lead to significant differences in health outcome, according to results of a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research.
Using mice as a model to study human breast cancer, researchers have demonstrated that a negative social environment (in this case, isolation) causes increased tumor growth. The work shows -- for the first time -- that social isolation is associated with altered gene expression in mouse mammary glands, and that these changes are accompanied by larger tumors.
EAST LANSING, Mich. - It's been cultivated for at least 7,000 years and spread from South America to grow on every continent except Antarctica. Now the humble potato has had its genome sequenced.
An international team, led by researchers from the University of California, San Diego School of Medicine and the National Eye Institute, has discovered gene variants for glaucoma in a black population. The finding could lead to future treatments or a cure for this disease, which leads to blindness in two million Americans each year.
Scientists have identified how a protein enables sections of so-called junk DNA to be cut and pasted within genetic code -- a finding which could speed development of gene therapies.
President Obama named nine researchers as recipients of the National Medal of Science, and four inventors and one company as recipients of the National Medal of Technology and Innovation, the highest honors bestowed by the United States government on scientists, engineers, and inventors. The recipients will receive their awards on October 7 at a White House ceremony.
WASHINGTON -- A report released today by the National Research Council calls on the United States to launch a new multiagency, multiyear, and multidisciplinary initiative to capitalize on the extraordinary advances recently made in biology and to accelerate new breakthroughs that could solve some of society's most pressing problems -- particularly in the areas of food, environment, energy, and
HANOVER, NH -- Two recent studies by Dartmouth researchers use individual genetic data to reveal the powers and limits of our current understanding of how the genome influences human health and what genes can reveal about the ancestry of the people of New Hampshire.
Sharing the fruits of research in the biomedical sciences is critical for the advance of knowledge, yet with the advent of large-scale data gathering following the completion of the genome projects this is becoming harder to facilitate and more difficult to monitor, as reported in Nature today.
A study from the Massachusetts General Hospital (MGH) Institute for Health Policy gives the first detailed look at the types of research currently being conducted within U.S. academic medical centers -- medical schools and their affiliated hospitals. The report in the Sept.
Drawing on the power of DNA sequencing, National Institutes of Health researchers have identified a new group of genetic mutations involved in the deadliest form of skin cancer, melanoma.
A newly designed computational method has proven its usefulness in counting copies of duplicated genome sequences and in doing initial assessments of their contents, according to a study to be published Aug. 30 in Nature Genetics. The number of copies of particular DNA segments can differ from one person to the next.
