Study sheds light on underlying neural mechanism behind macular degeneration

In macular degeneration, the most common form of adult blindness, patients progressively lose vision in the center of their visual field, thereby depriving the corresponding part of the visual cortex of input.

Discovery of novel genetic markers linked to increased risk of heart attack

An international team of researchers including scientists of Helmholtz Zentrum München has succeeded in identifying new gene variants associated with an increased risk for myocardial infarction (MI), or heart attack.

Statistical analysis could yield new drug target for multiple sclerosis

An elaborate statistical analysis of genes from more than 7,000 individuals has identified an amino acid that appears to be a major risk factor for multiple sclerosis, a devastating autoimmune disorder that afflicts 2.5 million people worldwide.

Genetics may predict risk for relapse among alcohol-dependent patients

In Poland, alcohol dependence (AD) affects about four percent of the population, causing about 10,000 deaths per year.

Blocking mechanism found for antibiotic resistance in bacteria

It's as simple as A, T, G, C. Northwestern University scientists have exploited the Watson-Crick base pairing of DNA to provide a defensive tool that could be used to fight the spread of antibiotic resistance in bacteria -- one of the world's most pressing public health problems.

A new approach improves prioritization of disease-associated SNPs

The more often a gene is differentially expressed, the more likely it is to contain disease-associated DNA variants.

Newborn neurons in the adult brain can settle in the wrong neighborhood

In a study that could have significant consequences for neural tissue transplantation strategies, researchers at the Salk Institute for Biological Studies report that inactivating a specific gene in adult neural stem cells makes nerve cells emerging from those precursors form connections in the wrong part of the adult brain.

A new role for a critical DNA repair molecule in the immune system

The human immune system is a brilliantly adaptable weapon against foreign invaders. But it all depends on the work of specialized cells called lymphocytes that have made a risky evolutionary gambit to mutate their own DNA.

Bladder problems may leave mark on brain contributing to sleep and attention problems

Bladder problems may leave a mark on the brain, by changing patterns of brain activity, possibly contributing to disrupted sleep and problems with attention. For one in six Americans who have overactive bladder, the involuntary bladder contractions that often trigger more frequent urges to urinate, such mind-body connections may be of more than academic interest.

Breakthrough in migraine genetics

In a new study, published in the American Journal of Human Genetics, researchers were able for the first time to convincingly demonstrate a genomic locus to be linked to migraine susceptibility in two diverse populations.

Genetic variants of USF1 are associated with the increased risk for cardiovascular disease

Cardiovascular diseases (CVD) are major contributors to morbidity and mortality worldwide.

Discovery of more genes involved in height

Scientists are beginning to develop a clearer picture of what makes some people stand head and shoulders above the rest.

Genetic variations raise lung cancer risk for smokers and ex-smokers

Two common inherited genetic variations are associated with increased risk of lung cancer for smokers and former smokers, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports April 2 in the online edition of Nature Genetics.

Racial differences in response to bowel cancer genetic risk factor

Scientists have for the first time discovered that people with the same cancer susceptibility genes respond differently depending on their race.

New genetic marker of risk for breast cancer discovered

An international group of investigators led by scientists at Memorial Sloan-Kettering Cancer Center (MSKCC) and the National Cancer Institute has identified a new genetic marker of risk for breast cancer.

Genomatix integrates genome-wide open chromatin from next generation sequencing

Genomatix Software GmbH, a Systems Biology company focussed on high quality annotation and the understanding of gene regulation, has begun showcasing its abilities in the analysis of data generated by Next Generation Sequencing (NGS) technology.

New understanding on the mechanics of gene transcription

The molecular machinery behind gene transcription -- the intricate transfer of information from a segment of DNA to a corresponding strand of messenger RNA -- isn't stationed in special "transcription factories" within a cell nucleus, according to Cornell researchers.

Brain abnormalities found underlying borderline personality disorder

Using new approaches, an interdisciplinary team of scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center in New York City has gained a view of activity in key brain areas associated with a core difficulty in patients with borderline personality disorder -- shedding new light on this serious psychiatric condition.

Evolution with a restricted number of genes

The development of higher forms of life would appear to have been influenced by RNA polymerase II.

Variant of a tumor suppressor gene associated with aggressive prostate cancer

A variant of a tumor suppressor gene may be associated with an increased risk of aggressive prostate cancer, according to a study published online December 11 in the Journal of the National Cancer Institute.
