Rapamycin epilepsy-prevention effect may be widely applicable

A drug with potential to prevent epilepsy caused by a genetic condition may also help prevent more common forms of epilepsy caused by brain injury, according to researchers at Washington University School of Medicine in St. Louis.

Exploiting cancer cell 'addiction' may lead to new therapies

A new study uncovers a gene expression signature that reliably identifies cancer cells whose survival is dependent on a common signaling pathway, even when the cells contain multiple other genetic abnormalities.

Glioblastoma may originate in neural stem cells

University of Michigan scientists have found that a deficiency in a key tumor suppressor gene in the brain leads to the most common type of adult brain cancer. The study, conducted in mice that mimic human cancer, points the way to more effective future treatments and a way to screen for the disease early.

Smoking and genetics play role in rheumatoid arthritis

Recent genetic studies have revealed several new sites of genes that are risk factors for developing rheumatoid arthritis (RA).

Oligophrenin-1 signaling protein linked to mental retardation controls synapse maturation, plasticity

A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has demonstrated the mechanism by which a signaling protein found throughout the brain controls the maturation and strength of excitatory synapses, the tiny gaps across which the majority of neurons communicate.

“Misreading” of histone code linked to human cancer

The development of blood from stem cell to fully formed blood cell follows a genetically determined program. When it works properly, blood formation stops when it reaches maturity. But when it doesn't, genetic mutations can prevent the stop signal and cause the developing cells to turn cancerous. In research published in Nature, Rockefeller University scientists show for the first time that a misreading of the blood cells' histone code is responsible for acute myeloid leukemia, a rare form of the deadly blood cancer.

MicroRNAs grease the cell's circadian clockwork

Most of our cells possess an internal clock, a group of genes displaying a cyclic expression pattern that reaches a peak once a day. A large number of circadian genes are expressed by organs such as the liver, whose activity needs to be precisely regulated over the course of the day.

Discovery of gene associated with a three-fold increase in risk for testicular cancer

Researchers at the University of Pennsylvania School of Medicine have uncovered variation around two genes that are associated with an increased risk of testicular cancer.

Combination of gene therapy and induced pluripotent stem cells cure human genetic disease in vitro

A study led by researchers at the Salk Institute for Biological Studies, has catapulted the field of regenerative medicine significantly forward, proving in principle that a human genetic disease can be cured using a combination of gene therapy and induced pluripotent stem (iPS) cell technology. The study, published in the May 31, 2009 early online edition of Nature, is a major milestone on the path from the laboratory to the clinic.

Genetic profiling reveals genes active in the earliest brain circuit construction

Long before the brain's neurons can facilitate life's big decisions, they have to find their own destiny in the rapidly developing embryo.

Genomic research lays groundwork for new approaches for treating, preventing skin diseases

The health of our skin - one of the body's first lines of defense against illness and injury - depends upon the delicate balance between our own cells and the millions of bacteria and other one-celled microbes that live on its surface.

Adult bone marrow stem cells injected into skeletal muscle can repair heart tissue

University at Buffalo researchers have demonstrated for the first time that injecting adult bone marrow stem cells into skeletal muscle can repair cardiac tissue, reversing heart failure.

New cellular targets for HIV drug development

Focusing HIV drug development on immune cells called macrophages instead of traditionally targeted T cells could bring us closer to eradicating the disease, according to new research from University of Florida and five other institutions.

Experimental therapy uses immune system to boost cure rate in neuroblastoma

A multicenter research team has announced encouraging results for an experimental therapy using elements of the body's immune system to improve cure rates for children with neuroblastoma, a challenging cancer of the nervous system.

Discovery of genetic cause for primary biliary cirrhosis

Researchers have discovered a novel molecular path that predisposes patients to develop primary biliary cirrhosis, a disease that mainly affects women and slowly destroys their livers. Primary biliary cirrhosis has no known cause.

Cohesin protein disrupts gene function in Cornelia deLange syndrome

An international team of scientists studying a rare genetic disease discovered that a bundle of proteins with the long-established function of keeping chromosomes together also plays an important role in regulating genes in humans.

New therapy shows potential for treating Duchenne muscular dystrophy

Researchers at the University of Minnesota Medical School have discovered a new therapy that shows potential to treat people with Duchenne muscular dystrophy, a fatal disease and the most common form of muscular dystrophy in children.

Discovery of faulty genes could reveal risk of Paget's disease

The discovery of faulty genes by Edinburgh researchers could help people with Paget's disease, a painful bone condition. Dr Omar Albagha has found three genes associated with the disease which, if detected early enough in people, could hasten diagnosis and treatment.

Scientists discover stem cell clue to lung cancer development

Cancer Research UK scientists have revealed that stem cells become 'activated' in severely damaged lungs and help to repair them, according to a study published in the Proceeding of the National Academy of Sciences today (Monday).

The evolution of gene regulation: How microbial neighbors settle differences

Even microbes are governed by the principle of supply and demand - at least at the genetic level. Not all of their gene products, the blueprints for proteins, are required at all times. That means most of their genes only become active when they are needed, as is the case in higher organisms.
