Aspirin offers help for Barrett's esophagus

Researchers at Fred Hutchinson Cancer Research Center have found that people with the most-aggressive form of Barrett's esophagus, a precancerous condition that can lead to esophageal cancer, may benefit the most from preventive therapy with aspirin, ibuprofen and other nonsteroidal anti-inflammatory drugs, or NSAIDs.

First 3-D structure from key influenza protein revealed

In 1918, 50 million people died during a worldwide influenza pandemic caused by mutation of a bird-specific strain of the influenza virus. Recently H5N1, another highly infectious avian strain has caused outbreaks of bird flu around the world.

microRNA directly regulates a gene implicated in human cancers

MicroRNAs are tiny snippets of RNA that can repress activity of a gene by targeting the gene's messenger RNA (which copies DNA information and starts the process of protein production).

microRNAs undergo molecular editing with significant physiological consequences

Tiny molecules called microRNAs, only 19 to 21 nucleotides in length, are able to effectively silence sometimes large sets of genes. They do this by specifically binding to and neutralizing another form of RNA called messenger RNA, responsible for conveying the information from genes to the cellular machinery that uses that information to create proteins, the building blocks of the body.

Entire genetic blueprints of more than 2,000 human and avian influenza viruses completed and made public

The Influenza Genome Sequencing Project, funded by the National Institute of Allergy and Infectious Diseases (NIAID), announced today that it has achieved a major milestone.

Scientists find new genes linked to Lou Gehrig's disease

In the first genome-wide search for the genetic roots of the most common form of amyotrophic lateral sclerosis (ALS), Johns Hopkins scientists have newly identified 34 unique variations in the human genetic code among 276 unrelated subjects with ALS.

How DNA is packed

The life cycles of many viruses include a self-assembly stage in which a powerful molecular motor must pack the DNA genome into the virus's preformed shell (the capsid). How it manages this intricate feat has been subject to debate, but we know that the DNA passes into the capsid shell through a channel formed by a structure called the connector. Scientists have speculated that rotation of the connector complex might feed the DNA into the capsid as it turns.

Genetic tendency toward suicide linked to genome on chromosome 2

A Johns Hopkins-led study has found evidence that a genetic tendency toward suicide has been linked to a particular area of the genome on chromosome 2 that has been implicated in two additional recent studies of attempted suicide.

Four genes identified that increase risk of developing type 2 diabetes

This form of diabetes is the most common worldwide and affects nearly 2 million Canadians. In recent years, the prevalence of Type 2 diabetes has increased rapidly. This genetic discovery may help stem this rise.

Results of largest ever genome study of autism released

The genomes of the largest collection of families with multiple cases of autism ever assembled have been scanned and the preliminary results published in Nature Genetics. They provide new insights into the genetic basis of autism.

Epigenetics to shape stem cell future

Everyone hopes that one day stem cell-based regenerative medicine will help repair diseased tissue. Before then, it may be necessary to decipher the epigenetic signals that give stem cells their unique ability to self-renew and transform them into different cell types.

At last the culprit in Autism is revealed

An international team of scientists have discovered two new genetic links that may predispose children to develop autism.

Kaiser Permanente launches long term project to collect genetic data

California-based HMO Kaiser Permanente on Wednesday announced the creation of a decades-long research project that will collect and analyze genetic information from hundreds of thousands of adult members, the San Jose Mercury News reports.

Genetic variations contribute to a person's risk for nicotine dependence

Americans are bombarded with antismoking messages, yet at least 65 million of us continue to light up. Genetic factors play an important role in this continuing addiction to cigarettes, suggest scientists at Washington University School of Medicine in St. Louis.

Largest collection of autism DNA

Preliminary findings from the largest genome scan ever completed in the history of autism research are being published in Nature Genetics. University of Pittsburgh researchers with a consortium of scientists from across the world contributed to this landmark research endeavor through the Autism Genome Project.

New Kaiser Permanente research aims to reveal genetic and environmental causes behind deadly and disabling diseases

The Kaiser Permanente Northern California Division of Research is launching one of the largest research projects in the United States to examine the genetic and environmental factors that influence common diseases such as heart disease, cancer, diabetes, high blood pressure, Alzheimer's disease, asthma and many others.

Variation in gene caspase-8 may help protect against breast cancer

A large-scale analysis of data on breast cancer risk has concluded that a common variation in the gene caspase-8 (CASP8) is associated with a somewhat lower risk of the disease. Variants are small changes that occur in a gene sequence.

13 Feb 2007

Type-2 diabetes genes identified

The most important genes associated with a risk of developing type-2 diabetes have been identified, scientists report today in a new study.

New method of screening tumors for cancer-related gene abnormalities

A study led by researchers at Dana-Farber Cancer Institute and Broad Institute of the Massachusetts Institute of Technology and Harvard University provides the first demonstration of a practical method of screening tumors for cancer-related gene abnormalities that might be treated with "targeted" drugs.
