Genetic variation for persons with diabetes linked to greater risk of coronary artery disease

Patients with type 2 diabetes who have poor glycemic control and a certain genetic variation have an increased risk of coronary artery disease, according to a study in the November 26 issue of JAMA, the Journal of the American Medical Association.

Discovery of novel drug target for chronic lymphocytic leukemia

Researchers at the University of California, San Diego (UCSD) and the Moores UCSD Cancer Center have discovered what could be a novel drug target for an often difficult-to-treat form of leukemia.

DNA variations of serotonin transporter gene can influence drinking intensity

The brain's serotonergic system plays an important role in alcohol preference and consumption.

Early detection program for men with a high prostate cancer risk

Men with a family history of prostate cancer and African-American men are particularly susceptible to the disease, with a twofold to sevenfold increased risk. Assessing risk in these populations has been difficult.

Researchers describe how cells recycle protein waste

Garbage collectors are important for removing trash; without them waste accumulates and can quickly become a health hazard.

Discovery of new biochemical pathway which controls DNA repair

From the sun's UVA rays to tobacco smoke, our environment is chock-full of DNA-damaging agents that can lead to cancer.

Scientists sequence genome of a cancer patient

For the first time, scientists have decoded the complete DNA of a cancer patient and traced her disease - acute myelogenous leukemia - to its genetic roots.

Variations in gene pathway alter risk of esophageal cancer

Variations in a common gene pathway may affect esophageal cancer risk, a dangerous and rapidly increasing type of cancer, according to research by scientists at The University of Texas M. D. Anderson Cancer Center.

Molecule stops DNA replication in its tracks

When a dividing cell duplicates its genetic material, a molecular machine called a sliding clamp travels along the DNA double helix, tethering the proteins that perform the replication.

Discovery of gene variant for cleft lip

About 20 percent of isolated cleft lip, one of the world's most common birth defects, may be due to a one-letter difference in the DNA sequence of a gene involved in facial development, researchers supported by the National Institutes of Health report.

Statin-induced muscle disorders are focus of $2.5 million in grants from NIH

Approximately 200,000 of the 38 million people in the U.S. who take statins to treat high cholesterol may develop life-threatening muscle disease.

Physical activity can blunt the effect of obesity genes

People who are concerned that they may have a genetic susceptibility for obesity will find some relief from new research conducted in the U.S.

Discovery of novel candidate gene for inflammatory bowel diseases

A study of Crohn's disease and ulcerative colitis in children has identified a gene that influences whether children get these diseases early in life, and points to a potential new target for treatment.

Evolution in the ribosome

A new study of the ribosome, the cell's protein-building machinery, sheds light on the oldest branches of the evolutionary tree of life and suggests that differences in ribosomal structure between the three main branches of that tree are "molecular fossils" of the early evolution of protein synthesis.

Scientists discover reservoir of mitochondrial DNA mutations present in the general population

Researchers at the University of Newcastle, England, and the Virginia Bioinformatics Institute at Virginia Tech in the United States have revealed a large reservoir of mitochondrial DNA mutations present in the general population. Clinical analysis of blood samples from almost 3,000 infants born in north Cumbria, England, showed that at least 1 in 200 individuals in the general public harbor mitochondrial DNA mutations that may lead to disease.

First cigarette "buzz", addiction linked to gene

Anyone who has ever tried smoking probably remembers that first cigarette vividly. For some, it brought a wave of nausea or a nasty coughing fit. For others, those first puffs also came with a rush of pleasure or "buzz."

A glimpse of ancient RNA

Some bacterial cells can swim, morph into new forms and even become dangerously virulent - all without initial involvement of DNA. Yale University researchers describe Friday in the journal Science how bacteria accomplish this amazing feat - and in doing so provide a glimpse of what the earliest forms of life on Earth may have looked like.

Common genetic variations increase risk of life-long nicotine addiction for young smokers

Common genetic variations affecting nicotine receptors in the nervous system can significantly increase the chance that European Americans who begin smoking by age 17 will struggle with life-long nicotine addiction. Published July 11 in the open-access journal PLoS Genetics, this research - led by scientists at the University of Utah together with colleagues from the University of Wisconsin - highlights the importance of preventing early exposure to tobacco through public health policies.

Researcher develops method for early detection of leukemia relapse

Researchers at the Fred Hutchinson Cancer Research Center have developed a method that allows for the early detection of a common mechanism of resistance on drug treatment for chronic myeloid leukemia.

Researchers to compare common ARV as a pill and vaginal gel in unique HIV prevention study

In battle with an epidemic that has outpaced nearly all efforts to contain it, researchers are turning to strategies centered on the same antiretroviral (ARV) drugs that have been used successfully to treat HIV in hopes they will be as effective a stronghold for preventing the virus.
