Transsexual genes identified

Australian scientists believe they have identified a significant link between a gene involved in testosterone and male-to-female transsexualism.

New gout drug offers hope for those who have exhausted treatment options

Researchers in the U.S. say a new drug effectively treats serious cases of gout - the drug called pegloticase mimics a blood-clearing enzyme missing in humans and helps remove the build up in uric acid, which causes the painful, needle-like crystals to collect around fingers, toes and other joints.

Human rhinovirus found to manipulate genes

Sneezing, runny nose and chills? You might blame the human rhinovirus (HRV), which causes 30 to 50 percent of common colds. But in reality, it's not the virus itself but HRV's ability to manipulate your genes that is the true cause of some of the most annoying cold symptoms.

Newly discovered mechanism can explain the Beckwith-Wiedemann syndrome

Researchers from Uppsala University have discovered a mechanism that silences several genes in a chromosome domain. The findings, published in today's on-line issue of Molecular Cell, have implications in understanding the human disorder Beckwith-Wiedemann syndrome.

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.

Mouse genes guide search for human anxiety disorder genes

We are all familiar with the question - "Are you a man or a mouse?" What if the answer is "a little of both"? Because of the power of molecular genetics research in animals and the maturation of animal models, the path to identifying genes involved in particular types of behavior, such as fear, is much clearer in animals than in humans.

Gene mutation in worms could further understanding of alcoholism in humans

The work follows a study carried out by Oregon Health and Science University, which suggested a link between a gene mutation in mice and tolerance to alcohol. Researchers at Liverpool have investigated this in worms, looking specifically at the role the gene plays in communication between cells in the nervous system.

Gene study sheds new light on lung cancer

A multi-institution team, funded by the National Human Genome Research Institute (NHGRI) of the National Institutes of Health (NIH), today reported results of the largest effort to date to chart the genetic changes involved in the most common form of lung cancer, lung adenocarcinoma. The findings should help pave the way for more individualized approaches for detecting and treating the nation's leading cause of cancer deaths.

Gene find sheds light on motor neuron diseases like amyotrophic lateral sclerosis

Scientists have identified a gene in mice that plays a central role in the proper development of one of the nerve cells that goes bad in amyotrophic lateral sclerosis, or Lou Gehrig's disease, and some other diseases that affect our motor neurons.

Education and work help beat Alzheimer's

New research has revealed that education and a mentally demanding job protects people from Alzheimer's disease.

Early-onset depressive disorders predict the use of addictive substances in adolescence

In a prospective study of over 1800 interviewed young Finnish twins, early-onset depressive disorders at age 14 significantly predicted daily smoking, smokeless tobacco use, frequent illicit drug use, frequent alcohol use and recurrent intoxication three years later, even among those adolescents who were not users at baseline.

Google.org helps identify future disease hot spots

Google.org, the philanthropic arm of Google, has announced grants of more than $14 million to support partners working in Southeast Asia and Africa to prevent the next pandemic.

Discovery of genetic switch critical for cell survival in Hypoxia

Researchers at the University of California, San Diego School of Medicine have identified a critical metabolic "switch" in fruit flies that helps oxygen-deprived cells survive. "A transcriptional suppressor, called hairy, is crucial for reducing the mismatch between supply and demand of oxygen," said Dan Zhou, first author on the study, published October 17 in the open-access journal PLoS Genetics.

Gene could 'knock the sox' off cancer!

Australian scientists from the Institute for Molecular Bioscience at The University of Queensland (UQ), have identified a gene which could very well 'knock the sox' off cancer and lymphatic disorders.

FDA grants orphan drug status to new 'Trojan Horse' like Ewing's Sarcoma drug

The Cure Our Children Foundation, a nonprofit charitable foundation dedicated to children, announced today that the U.S. Food and Drug Administration (FDA) has approved the Orphan Drug Designation of the foundation's unique drug product for children with Ewing's Sarcoma cancer. The efforts to develop this drug were made possible by the generous volunteers and researchers in private industry and at two universities.

Getting to grips with the complexity of disease proteins

Drug molecules seldom act simply on one protein but on protein complexes and networks. A deeper understanding of these 'cooperative assemblies' should lead to better targeting of drugs.

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.

Genes that control cell death may play role in age-related hearing loss

Several genes that play a role in how our body's cells normally auto-destruct may play a role in age-related hearing loss, according to research published online in the journal Apoptosis - a journal devoted to the topic of cell suicide, or programmed cell death.

Nicotine linked to breast cancer growth and spread

A study published in Cancer Research, a journal of the American Association for Cancer Research, suggests a possible role for nicotine in breast tumor development and metastases.

Discovery of two novel gene locations that raise risk of type 1 diabetes

Genetics researchers have identified two novel gene locations that raise the risk of type 1 diabetes. As they continue to reveal pieces of the complicated genetic puzzle for this disease, the researchers expect to improve predictive tests and devise preventive strategies.
