Researchers reveal stress-induced machinery of protein synthesis involved in bacterial cell death

Researchers at the Hebrew University of Jerusalem and the University of Vienna have revealed for the first time a stress-induced machinery of protein synthesis that is involved in bringing about cell death in bacteria.

Ribosomes spontaneously change their form during protein production

Ribosomes, the construction sites for proteins, are far more complex than previously assumed. During the production of proteins they constantly and spontaneously change their form. This performance of eukaryotic ribosomes has now been demonstrated for the first time by scientists at Charité - Universitätsmedizin Berlin, the Max-Planck-Institut für Molekulare Genetik in Berlin, and Cornell University in New York, with the aid of special electron microscopic and biophysical methods.

GPS at WUSTL now offers new cancer genetic test

Physicians can now take advantage of a new genetics test -- one of the first of its kind to be offered in the United States -- that can help determine the best treatment for cancer patients.

New method for counting molecules

Researchers at the Swedish medical university Karolinska Institutet have developed a new method for counting molecules.

Flu strains migrate back and forth between different regions of the world

Influenza researchers have found that flu strains migrate back and forth between different regions of the world, evolving along the way. This is contrary to the common belief that flu strains from the tropics are the source of global seasonal epidemics.

Ground-breaking study into causes of high blood pressure

A researcher from the University of Leicester's Department of Cardiovascular Sciences has been involved in a ground-breaking study into the causes of high blood pressure.

Novel mathematical method reveals genetic distinction between individuals

At a time when profound gaps remain in our understanding of how one person's genes differ from another person's, developing accurate methods to interpret the human genome is essential to uncover population history, population relationships and the genetic basis of some of the most common diseases affecting society.

Prefrontal cortex neurons from individuals with autism show changes in chromatin structures

Neurons in the prefrontal cortex of individuals with autism show changes at numerous sites across the genome, according to a study being published Online First by the Archives of General Psychiatry, one of the JAMA/Archives journals.

Epigenetic alterations may play an important role in autism

Scientists at the University of Massachusetts Medical School are the first to map epigenetic changes in neurons from the brains of individuals with autism, providing empirical evidence that epigenetic alterations-changes in gene expression caused by mechanisms other than changes in the underlying DNA sequence-may play an important role in the disease.

Evolutionary 'breakpoints' on chromosomes may lead to canine cancer

North Carolina State University researchers have uncovered evidence that evolutionary "breakpoints" on canine chromosomes are also associated with canine cancer. Mapping these "fragile" regions in dogs may also have implications for the discovery and treatment of human cancers.

Bacteria rapidly exchange genetic information related to human disease and antibiotic resistance

Much as people can exchange information instantaneously in the digital age, bacteria associated with humans and their livestock appear to freely and rapidly exchange genetic material related to human disease and antibiotic resistance through a mechanism called horizontal gene transfer (HGT).

VUMC doctors to begin statin drug screening for rare genetic variation

Vanderbilt University Medical Center doctors announced today they will begin screening patients who take commonly prescribed statin drugs for a rare genetic variation that can increase risks for side effects from these drugs such as muscle aches, kidney damage and even death.

AD risk genes impact Aβ toxicity in neurons

In a development that sheds new light on the pathology of Alzheimer's disease (AD), a team of Whitehead Institute scientists has identified connections between genetic risk factors for the disease and the effects of a peptide toxic to nerve cells in the brains of AD patients.

Medco, Pfizer and UBC collaborate to enhance precision medicine approach

Pfizer Inc. announced today that it has established a research collaboration with Medco Health Solutions, Inc. and its wholly owned subsidiary, United BioSource Corporation (UBC), aimed at more effectively matching patients with treatments that will benefit them the most, thereby improving patient outcomes.

NIH awards DNASU $6.5M grant to expand Protein Structure Initiative-Materials Repository

Arizona State University's Biodesign Institute- is home to a rich trove of biological material. Known as DNASU, this growing storehouse-a sort of genetic Library of Congress-holds over 147,000 plasmids, (circular DNA samples that can be used to produce individual proteins), as well as full genome collections from numerous organisms and proteins associated with many leading human diseases.

NextBio predicts mechanisms underlying drug toxicity and identifies new cancer biomarker

New research presented this week highlights the ability of NextBio to help life scientists and clinicians investigate publicly available genomic data to assess biological mechanisms underlying drug toxicity, as well as discover prospective cancer biomarkers for further validation.

BCL11A protein might serve as potential target for sickle cell disease

Flipping a single molecular switch can reverse illness in a model of sickle cell disease, according to a study by researchers at Children's Hospital Boston and Dana-Farber Cancer Institute. When turned off, the switch, a protein called BCL11A, allows the body to manufacture red blood cells with an alternate form of hemoglobin unaffected by the mutation that causes the disease.

Scientisits uncover evidence of powerful new cancer genetic networks

In findings with major implications for the genetics of cancer and human health, researchers at Beth Israel Deaconess Medical Center (BIDMC) and two other science teams in New York City and Rome have uncovered evidence of powerful new genetic networks and showed how it may work to drive cancer and normal development.

Study reveals new regulatory elements in human genome

An international research team led by Kerstin Lindblad-Toh at the Broad Institute, US and Uppsala University, Sweden has mapped and compared the genomes of 29 mammals. The findings, published in Nature, reveal millions of new regulatory elements in the human genome that in various ways govern how proteins are formed. The new knowledge is important for our understanding of how mutations in human genes give rise to diseases.

Raw fruits and veggies may offset genetic risk for heart disease: Study

In a new study a team of researchers looked at the genotypes of 27,243 people from two separate studies to see if they had a certain gene variant. Earlier studies including a 2010 meta-analysis in the Journal of the American Medical Assn. found that the 9p21 gene is associated with a higher risk of heart attack and cardiovascular disease.
