Wyss Founding Director receives NC3Rs 3Rs Prize for Lung-on-a-Chip

In a London ceremony today, Wyss Founding Director Don Ingber, M.D., Ph.D., received the NC3Rs 3Rs Prize from the UK's National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) for his innovative Lung-on-a-Chip -- a microdevice lined by human cells that recapitulates complex functions of the living lung.

Loss of Dickopf-1 restores neurogenesis and memory in animal model

Loss of the molecule Dickopf-1 in the hippocampus in older animals increases neurogenesis, research shows.

Researchers determine that neuroblastoma is sensitive to BET bromodomain inhibitors

Neuroblastoma, the most common malignant tumor of early childhood, is frequently associated with the presence of MYCN amplification, a genetic biomarker associated with poor prognosis. Researchers have determined that tumors containing MYCN amplification are sensitive to a new class of drugs, BET bromodomain inhibitors.

Study may help design better DAA drug cocktails to treat HCV

Hepatitis C virus (HCV) infection affects about 4 million in the United States and is the primary cause of liver cirrhosis and liver cancer. Current therapy against HCV is suboptimal. Daclatasvir, a direct acting antiviral (DAA) agent in development for the treatment of HCV, targets one of the HCV proteins (i.e., NS5A) and causes the fastest viral decline (within 12 hours of treatment) ever seen with anti-HCV drugs.

UCLA plays a vital role in ongoing research into Rasmussen encephalitis

How do you find a cure for a devastating pediatric brain disease so rare that it can take decades to build a meaningful research base? In 2010, the parents of a patient created the Rasmussen Encephalitis (RE) Children's Project to help solve this problem. In a short amount of time, the foundation has raised funds to establish a consortium of top researchers, build a collection of samples of the disease from around the world and support projects to study the disease tissue and search for genetic links. The goal is to find a cure.

Researchers explore cellular signals produced by the body in response to traumatic injury

When it comes to healing the terrible wounds of war, success may hinge on the first blood clot - the one that begins forming on the battlefield right after an injury. Researchers exploring the complex stream of cellular signals produced by the body in response to a traumatic injury believe the initial response - formation of a blood clot - may control subsequent healing.

Parkinson's-related mutations may also affect vision

The most common genetic cause of Parkinson's is not only responsible for the condition's distinctive movement problems but may also affect vision, according to new research by scientists at the University of York.

TSG might be novel compound for treatment of Alzheimer's and dementia with Lewy body

Administration of the active compound tetrahydroxystilbene glucoside (TSG) derived from the Chinese herbal medicine Polygonum multiflorum Thunb, reversed both overexpression of α-synuclein, a small protein found in the brain, and its accumulation using a mouse model of Alzheimer's disease.

Scopolamine may also be possible treatment for anxiety disorders

However, scopolamine is re-emerging as an antidepressant, with recent studies showing that scopolamine can rapidly improve mood in depressed patients. In addition, in a new study published in Biological Psychiatry this month by Dr. Moriel Zelikowsky and colleagues at the University of California, Los Angeles, it may also be a possible treatment for anxiety disorders.

Single gene therapy session can cure diabetes

Researchers from the Universitat Aut-noma de Barcelona (UAB), led by F-tima Bosch, have shown for the first time that it is possible to cure diabetes in large animals with a single session of gene therapy. As published this week in Diabetes, the principal journal for research on the disease, after a single gene therapy session, the dogs recover their health and no longer show symptoms of the disease.

DHEA-S may prevent neurocognitive impairment that affects AIDS patients

A team of scientists from Canada, Thailand and Morocco have found that DHEA-S may prevent neurocognitive impairment that affects a significant percentage of AIDS patients. In a report appearing in the February 2013 issue of The FASEB Journal, they describe how a network of steroid molecules found in the brain, termed "neurosteroids," is disrupted during HIV infection leading to brain damage.

Moderate gum disease causes severe infection and inflammation in AIDS animal model

Texas Biomed scientists in San Antonio have found that moderate gum disease in an animal model exposed to an AIDS- like virus had more viral variants causing infection and greater inflammation. Both of these features have potential negative implications in long term disease progression, including other kinds of infections, the researchers say in a new report.

MiR-182 deeply involved in memory formation within the amygdala brain structure

It takes a lot to make a memory. New proteins have to be synthesized, neuron structures altered. While some of these memory-building mechanisms are known, many are not. Some recent studies have indicated that a unique group of molecules called microRNAs, known to control production of proteins in cells, may play a far more important role in memory formation than previously thought.

Hydrogen sulfide may play a wide-ranging role in staving off aging

Hydrogen sulfide (H2S) may play a wide-ranging role in staving off aging, according to a paper published online ahead of print in the journal Molecular and Cellular Biology.

Findings could help explain prevalence of urinary tract infections in post-menopausal women

Researchers from Washington University School of Medicine, St. Louis, show that reservoirs of uropathogenic E. coli within the bladder exist in higher numbers post-menopause than pre-menopause in a mouse model, a finding that could help explain the greater prevalence of urinary tract infections in post-menopausal women.

Possible connection between mitochondrial CYP2D6 and Parkinson's

With a new insight into a model of Parkinson's disease, researchers from the University of Pennsylvania School of Veterinary Medicine have identified a novel target for mitigating some of the disease's toll on the brain.

New model of tau pathology spread

Brain diseases associated with the misformed protein tau, including Alzheimer's disease and frontotemporal lobar degeneration with tau pathologies, are characterized by neurofibrillary tangles (NFTs) comprised of pathological tau filaments.

Potential stem cell therapy for Duchenne’s

Researchers have found that injecting aorta-derived stem cells into the hearts of dystrophin-deficient mice prevents the onset of dilated cardiomyopathy, raising hopes of a potential new treatment approach to prevent or reverse the condition in human Duchenne muscular dystrophy.
