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.

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.

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.

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.

Beyond recognizing odors, a single neuron controls reactions

Babies will smile when they catch the scent of vanilla, but a whiff of rotting meat will send them into fits. From people to mice and flies to worms, animals of all kinds are born with likes and dislikes thanks to the evolutionary wisdom collected in their genes. But new research shows that some preferences are still surprisingly flexible at even the most basic level - that of the sensory neuron itself - and that our nervous system may be even more adaptable than we thought.

Universal vaccine could protect people and pets from deadly flu pandemics

A single vaccine could be used to protect chickens, cats and humans against deadly flu pandemics, according to an article published in the November issue of the Journal of General Virology. The vaccine protects birds and mammals against different flu strains and can even be given to birds while they are still in their eggs, allowing the mass vaccination of wild birds.

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.

Altruistic behaviour can be sexually attractive to others

Displays of altruism or selflessness towards others can be sexually attractive in a mate. This is one of the findings of a study carried out by biologists and a psychologist at The University of Nottingham.

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.

1 in 7 men destined to go bald due to genes

Scientists have discovered that 1 in 7 men have a genetic risk for baldness. Researchers at Canada's McGill University and King's College London along with scientists at drug company GlaxoSmithKline have solved the mystery of male pattern baldness but say treating it will require more research.

Landmark study unlocks stem cell, DNA secrets to speed therapies

In a groundbreaking study led by an eminent molecular biologist at Florida State University, researchers have discovered that as embryonic stem cells turn into different cell types, there are dramatic corresponding changes to the order in which DNA is replicated and reorganized.

Male baldness gene in Caucasians discovered

Researchers at McGill University, King's College London and GlaxoSmithKline Inc. have identified two genetic variants in caucasians that together produce an astounding sevenfold increase the risk of male pattern baldness. Their results will be published Oct. 12 in the journal Nature Genetics.

Inherited disorders and copy number changes in human alpha-globin genes

A researcher from the University of Leicester has shed new light on the way genetic material is exchanged between chromosomes, the effect this 'aberrant exchange' has had on inherited disorders like thalassaemia (a form of anaemia), and its link with malaria.
