Mutant gene that starves the brain of serotonin 10 times more prevalent in depressed patients

A mutant gene that starves the brain of serotonin, a mood-regulating chemical messenger, has been discovered and found to be 10 times more prevalent in depressed patients than in control subjects, report researchers funded by the National Institutes of Health’s National Institute of Mental Health (NIMH) and National Heart Lung and Blood Institute (NHLBI).

Blocking gene's activity may control deadly skin cancer without harming normal cells

Researchers at Dana-Farber Cancer Institute and Children's Hospital Boston have discovered that malignant melanoma, the potentially lethal skin cancer, can't grow without a steady supply of a protein that normal cells can do without.

DLX5 gene may play a role in the pathology of Rett Syndrome

A research team led by Terumi Kohwi-Shigematsu of the Life Sciences Division of Lawrence Berkeley National Laboratory has identified a gene, DLX5, that may play a role in the pathology of Rett Syndrome, a devastating neurological disorder diagnosed almost exclusively in girls.

Rett Syndrome, the first identified epigenetic disease - linked to specific defects in the three-dimensional folding of chromatin

Sometime between the age of 6 and 18 months, after a period of seemingly normal development, girls affected with Rett Syndrome lose interest in play; they gradually become withdrawn and anxious, develop autistic-like behaviors, and acquire specific symptoms like repetitive teeth-grinding and hand-wringing.

Low-dose diuretic therapy for most patients with hypertension recommended

Patients with high blood pressure who take calcium channel blockers and diuretics have an increased risk for cardiovascular disease (CVD) death compared to patients who take beta-blockers plus diuretics, according to a study in the current issue of JAMA.

Scientists have identified a novel anti-tuberculosis (TB) compound

Scientists at Johnson & Johnson Pharmaceutical Research and Development have identified a novel anti-tuberculosis (TB) compound that works better and faster than the current standard of care in mouse models of TB infection.

Celebrex like gene suppresses the growth of colon cancer

Cancer researchers at the Case Western Reserve University (Case) School of Medicine, University Hospitals of Cleveland (UHC) and the Howard Hughes Medical Institute have found a "Celebrex-like" gene that suppresses the growth of colon cancer.

Compounds in Christmas trees could help treat arthritis and pain

Researchers have identified a group of anti-inflammatory compounds in the bark of the Scotch pine - widely used for Christmas trees - that they say could be developed into food supplements or drugs for treating arthritis and pain.

Findings could lead to new knowledge that could speed the development of drugs to block botulism or tetanus toxins more rapidly

The first detailed structure of a botulism toxin attached to its target protein reveals that the toxin snakes the protein around itself — a sort of “reverse anaconda” — to recognize the receptor.

Molecular Achilles heel in the organism that causes pneumonia

Scientists have found a “molecular Achilles heel” in the organism that causes pneumonia, providing a target for the development of a new class of antibiotics that could eventually eradicate the disease.

Newly discovered genetic defect might represent an important risk factor for major depression

A newly discovered genetic defect might represent an important risk factor for major depression, a condition which effects 20 million people in the U.S., according to Duke University Medical Center researchers.

Model may explain how alcohol stimulates tumor growth

The investigators found that compared to the saline control group, the embryos exposed to ethanol experienced increases in tumor size, tumor blood vessel density, cancer cell infiltration of blood vessels, and VEGF levels.
