Researchers discover gene for new form of intellectual disability

Researchers at the Centre for Addiction and Mental Health (CAMH) led a study discovering a gene for a new form of intellectual disability, as well as how it likely affects cognitive development by disrupting neuron functioning.

Gas NO plays a fundamental regulatory role in controlling bacterial function

Bacteria provide a well-known playground for scientists and the evolution of these earliest life forms has shed important perspective on potential therapies for some of the most common, deadly diseases. Researchers at Case Western Reserve University School of Medicine have now discovered that, the gas nitric oxide (NO), produced in all cells of the human body for natural purposes, plays a fundamental regulatory role in controlling bacterial function, via a signaling mechanism called S-nitrosylation (SNO), which binds NO to protein molecules.

Kras gene triggers metabolic changes that fuel cancer cells

Researchers at Dana-Farber Cancer Institute have shown that advanced pancreatic cancers in mice can't survive without continued expression of a mutant oncogene that "rewires" key metabolic pathways to fuel the cancer cells.

Combination of Velcade and Fasudil could treat NSCLC

A common cancer drug and a drug used for a rare condition affecting the heart could together treat an aggressive form of lung cancer called non-small cell lung cancer (NSCLC), according to a study published in Cell today.

FDA approves Novartis’ Afinitor for treatment of renal angiomyolipomas and TSC

Novartis Pharmaceuticals Corporation announced today that the US Food and Drug Administration (FDA) approved Afinitor (everolimus) tablets for the treatment of adult patients with kidney tumors known as renal angiomyolipomas and tuberous sclerosis complex (TSC), who do not require immediate surgery.

Experimental drug for autism works effectively in laboratory mice: Study

A new experimental drug has shown promise in autism symptoms in mice. Researchers from the National Institutes of Mental Health and Pfizer reported Wednesday that an experimental compound, called GRN-529, increased social interactions and lessened repetitive self-grooming behavior in a strain of mice bred to display autism-like behaviors.

Fragile-X gene linked with disrupting de novo mutations in children with autism

A team led by scientists at Cold Spring Harbor Laboratory (CSHL) publishes research today indicating a striking association between genes found disrupted in children with autism and genes that are targets of FMRP, the protein generated by the gene FMR1, whose dysfunction causes Fragile-X syndrome.

Study shows how PCBs could add to autism risk

New research from UC Davis and Washington State University shows that PCBs, or polychlorinated biphenyls, launch a cellular chain of events that leads to an overabundance of dendrites - the filament-like projections that conduct electrochemical signals between neurons - and disrupts normal patterns of neuronal connections in the brain.

Physical activity reduces oxidative stress in people with SCT

Sickle cell disease (SCD), an inherited condition that causes red blood cells to sometimes deform into a crescent shape, affects an estimated 100,000 Americans, typically those of African descent. However, far more have sickle cell trait (SCT), caused when individuals carry just a single copy of the disease-causing mutation in their genes.

Laws against cousin marriage are not supported by science: New book

The health risks of marrying a cousin have been grossly overstated, says a new book. A better understanding of the health effects of cousin marriage could mean more appropriate marriage laws and better medical care for cousin couples and their children.

P-bodies have a much broader role in controlling the activities of the cell than previously thought

Cells can reuse the chemical messengers that carry genetic information to the machinery that makes proteins. Sometimes cells shuttle the messengers to storage and later reactivate them to make proteins, according to new research.

Researchers discover two new genetic loci for obesity

Obesity is influenced environmental and genetic factors. The genetic predisposition accounts for more than 50 percent of the variance in body weight. Roughly three dozen genes are known to have an influence on body weight regulation. Together with international colleagues, a group of scientists of the University of Duisburg-Essen (UDE) has identified two new genetic loci for obesity. The results are part of a large international study.

UT Southwestern lung transplant recipient lives through 19 years

UT Southwestern Medical Center has performed more than 300 lung transplants in recent decades, and Michael Young represents a remarkable success story.

Bile plays a critical role in development of Barrett's esophagus

For many people with gastroesophageal reflux disease or GERD, acid reflux drugs are the answer to their woes, curbing the chronic heartburn and regurgitation of food or sour liquid characteristic of the disorder. But when it comes to Barrett's esophagus, a condition commonly found in people with GERD, acid control may be less important than beating back another bodily fluid - bile.

MMP-10 gene plays a dual role in lung cancer

A single gene that promotes initial development of the most common form of lung cancer and its lethal metastases has been identified by researchers at Mayo Clinic in Florida.

Non-coding RNA gives off biological signals during viral infection

Once considered unimportant "junk DNA," scientists have learned that non-coding RNA (ncRNA) - RNA molecules that do not translate into proteins - play a crucial role in cellular function. Mutations in ncRNA are associated with a number of conditions, such as cancer, autism, and Alzheimer's disease.

U-M project to examine link between bipolar disorder and abnormalities in the circadian

A math professor at the University of Michigan will lead an international, $1 million project examining the links between bipolar disorder and abnormalities in the circadian, or daily, rhythms of a mammal's internal clock.

Clinical trial to evaluate IGF-1 in children with SHANK3 deficiency

In an important test of one of the first drugs to target core symptoms of autism, researchers at Mount Sinai School of Medicine are undertaking a pilot clinical trial to evaluate insulin-like growth factor (IGF-1) in children who have SHANK3 deficiency (also known as 22q13 Deletion Syndrome or Phelan-McDermid Syndrome), a known cause of autism spectrum disorder (ASD).

Study shows how acupuncture therapy holds promise for skeletal muscle atrophy

A team of Japanese researchers will reveal study results Monday at the Experimental Biology 2012 meeting that show how acupuncture therapy mitigates skeletal muscle loss and holds promise for those seeking improved mobility through muscle rejuvenation.

Novel technological treatment for Leber Hereditary Optic Neuropathy

A research team, led by John Guy, M.D., professor of ophthalmology at Bascom Palmer Eye Institute of the University of Miami Miller School of Medicine, has pioneered a novel technological treatment for Leber Hereditary Optic Neuropathy (LHON), an inherited genetic defect that causes rapid, permanent, and bilateral loss of vision in people of all ages, but primarily males ages 20-40.
