Genetically caused deafness may be reversible by compensating for a missing protein

Emory University researchers have found that in mice, increasing the amount of the protein connexin26 in the ear's cochlea compensates for an absence of another protein, connexin30.

Old drug pentylenetetrazole may improve learning and memory in Down syndrome victims

Researchers in the United States have discovered that an old drug once used to study epilepsy substantially improved learning and memory in mice with Down syndrome symptoms.

Irregular heartbeat linked to genetic mutation

Every day for 10 years, a seemingly heart-healthy 53-year-old woman experienced rapid and irregular heartbeats. She had no personal or family history of hypertension or hyperthyroidism. She did not suffer from myocardial or coronary artery disease, or any abnormalities of the heart as best doctors and medical science could determine.

Apolipoprotein C1 protein linked to elevated BMI in people of American Indian and Mexican ancestry

University of Minnesota researchers have discovered a variant of a common blood protein, apolipoprotein C1, in people of American Indian and Mexican ancestry that is linked to elevated body mass index (BMI), obesity and Type 2 diabetes.

Why are African American women more likely than White women to die from breast cancer?

Why are African American women 1.5 to 2.2 times more likely than White women to die from breast cancer, despite their lower incidence of the disease? Is it solely because they have less access to medical care? Maybe not, according to a new analysis that will appear in an upcoming issue of the International Journal of Surgery.

Abnormalities in eye movements and attention define risk for schizophrenia

A Binghamton University researcher has established a new framework to help determine whether individuals might be at risk for schizophrenia.

Reduced brain growth in alcoholics with family drinking history

The brains of alcohol-dependent individuals are affected not only by their own heavy drinking, but also by genetic or environmental factors associated with their parents- drinking, according to a new study by researchers at the National Institute on Alcohol Abuse and Alcoholism (NIAAA).

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.

Low-cost Parkinson's disease diagnostic test a world first

Scientists at Melbourne's Howard Florey Institute have developed a cost-effective diagnostic test for Parkinson's disease (PD), which will also assist researchers to understand the genetic basis of PD and to undertake large-scale studies to identify the genes that cause this debilitating condition.

Anorexia nervosa may be genetic

A researcher in the United States says a ten year study into the eating disorder anorexia nervosa suggests that sufferers may have a genetic predisposition for it.

New test identifies suitable lymphoma patients likely to respond to new therapy

Researchers at the Albert Einstein College of Medicine of Yeshiva University have discovered a genetic signature identifying cases of lymphoma that are uniquely susceptible to a newly developed molecular targeted therapy. As a result, physicians organizing clinical trials of the new therapy will be able to enroll patients who'll be most likely to benefit from it.

Cancer cells 100 times more likely to genetically mutate

When cells become cancerous, they also become 100 times more likely to genetically mutate than regular cells, researchers have found. The findings may explain why cells in a tumor have so many genetic mutations, but could also be bad news for cancer treatments that target a particular gene controlling cancer malignancy.

Newborns with respiratory distress should be evaluated for primary ciliary dyskinesia

Reviewing published reports, Ferkol and Margaret Leigh, M.D., professor of pediatrics at the University of North Carolina at Chapel Hill (UNC), found that neonatal respiratory distress was a common clinical symptom of PCD, a chronic airway disease that affects about 1 in 15,000 children.

Transmission of drug-resistant tuberculosis among treated patients in Shanghai

A newly released study suggests that the majority of cases of drug-resistant tuberculosis (TB) among patients undergoing treatment for the disease may be due to new infections, not acquired resistance.

siRNA delivery into human T cells and primary cells with carbon-nanotube transporters

A promising approach to gene therapy involves short DNA fragments (interfering RNA) that bind to specific genes and block their "translation" into the corresponding, disease-related protein.

Expert questions validity of genetic testing patents

Molecular Pathologist-Attorney Roger D. Klein in a letter published in the February 15, 2007 issue of the New England Journal of Medicine questioned the validity of patents often used to prevent clinical laboratories from performing certain genetic tests.
