Researchers pinpoint gene mutations responsible for 10 percent of non-familial cases of schizophrenia

Scans of the genome of patients with schizophrenia have revealed rare spontaneous copy number mutations that account for at least 10 percent of the non-familial cases of the disease.

Tumor suppressor genes speed up and slow down aging in engineered mouse

Mayo Clinic researchers have developed an animal model that can test the function of two prominent tumor suppressor genes, p16 and p19, in the aging process. Scientists knew that both these genes were expressed at increased levels as humans and mice age, but their role in the aging process was not clear. Findings by the Mayo team show that p16 provides gas to accelerate cellular aging, while p19 stops that process.

Soil bacteria may offer potential treatments for MRSA and cancer

Big pharma gave up on soil bacteria as a source of antibiotics too soon, according to research published in the June issue of Microbiology. Scientists have been mining microbial genomes for new natural products that may have applications in the treatment of MRSA and cancer and have made some exciting discoveries.

New research into superbug Clostridium difficile

New research into the toxins, virulence, spread and prevention of the superbug Clostridium difficile is reported in the June special issue of the Journal of Medical Microbiology. These findings will play a crucial role in providing us with ammunition in the fight against a sometimes deadly pathogen.

New insight into the genetics of Lou Gehrig's disease

An upcoming paper from Drs. Hidenori Ichijo and Hideki Nishitoh (The University of Tokyo) and colleagues lends new and valuable insight into the genetics of ALS.

How advanced prostate cancer becomes resistant to androgen-deprivation therapy

For the past 70 years the treatment of choice for advanced, metastatic prostate cancer has been androgen-deprivation therapy. That is, the suppression of circulating testosterone - the hormone that fuels prostate-cancer growth - via surgical castration (orchiectomy) or medical castration with testosterone-blocking drugs. While such therapy buys time for patients, it is not a cure, as inevitably the cancer becomes resistant to the androgen deprivation and continues to grow.

X chromosome exposed

An enzyme that binds differently to male and female sex chromosomes helps males to make up for their X chromosome shortage.

Self-assembled viruses

Viruses are true experts at importing genetic material into the cells of an infected organism. This trait is now being exploited for gene therapy, in which genes are brought into the cells of a patient to treat genetic diseases or genetic defects. Korean researchers have now made an artificial virus. As described in the journal Angewandte Chemie, they have been able to use it to transport both genes and drugs into the interior of cancer cells.

Spontaneous mutations widespread in non-familial schizophrenia

People with schizophrenia from families with no history of the illness were found to harbor eight times more spontaneous mutations - most in pathways affecting brain development - than healthy controls, in a study supported in part the National Institutes of Health?s (NIH) National Institute of Mental Health (NIMH). By contrast, no spontaneous mutations were found in people with schizophrenia who had family histories of the illness.

Rett syndrome gene found to be full of surprises

A study funded by the National Institutes of Health (NIH) has transformed scientists' understanding of Rett syndrome, a genetic disorder that causes autistic behavior and other disabling symptoms. Until now, scientists thought that the gene behind Rett syndrome was an "off" switch, or repressor, for other genes. But the new study, published today in Science, shows that it is an "on" switch for a startlingly large number of genes.

Timer genes control brain size

Experiments using fruit flies have helped a team at the MRC National Institute for Medical Research to identify genes that control how large the developing brain becomes.

Fireflies' glow helps researchers track cancer drug's effectiveness

The gene that allows fireflies to flash is helping researchers track the effectiveness of anti-cancer drugs over time.

Why do Finnish children have type 1 diabetes and allergic symptoms approximately five times more often than children in Russian Karelia?

High living standards and the life style connected to them seem to promote the development of autoimmune diseases and allergic symptoms. This has lead to the assumption that the immune system begins to overreact to the organism's own structures or to exogenous non-infectious proteins, i.e. allergens, when it does not have to work hard enough to protect the individual from infections.

New cancer stem cell identified behind metastatic tumors

The molecular profile of cancer stem cells that initiate metastatic colon tumors is significantly different from those responsible for primary tumors, according to new research from a team at Weill Cornell Medical College.

Estrogen drives distinct, aggressive prostate cancer

Using a breakthrough technology, researchers led by a Weill Cornell Medical College scientist have pinpointed the hormone estrogen as a key player in about half of all prostate cancers.

Allergy - it's in the genes

In a world first scientists at theWestmead Millennium Institute have identified how a gene associated with allergic diseases such as asthma and eczema works, providing new hope for potential drug treatments.

Scientists sequence first female DNA

Geneticists of Leiden University Medical Centre (LUMC) are the first to determine the DNA sequence of a woman. She is also the first European whose DNA sequence has been determined. This has been announced by the researchers this morning, during a special press conference at 'Bessensap', a yearly meeting of scientists and the press in the Netherlands.

Avoiding spleen removal for Cooley's anemia sufferers

Researchers from Weill Cornell Medical College may have discovered the precise role of a gene in one of the world's most common blood disorders, beta-thalassemia, commonly known as Cooley's anemia. Along with sickle-cell anemia, Cooley's anemia is the most commonly inherited disease in the world, affecting many people of Mediterranean descent, and 20 out of every 100,000 African-Americans. The World Health Organization estimates that between 50,000-100,000 children are born with the disease each year.

RNA toxicity contributes to neurodegenerative disease

Expanding on prior research performed at the University of Pennsylvania, Penn biologists have determined that faulty RNA, the blueprint that creates mutated, toxic proteins, contributes to a family of neurodegenerative disorders in humans.

Alpha1-antitrypsin deficiency associated with increased risk of lung cancer

Carriers of a common genetic disorder previously linked to lung disease may have a 70-percent to 100-percent increased risk of lung cancer, according to a report in the May 26 issue of Archives of Internal Medicine
