Scientists wrestle to understand why Huntington's can produce variable symptoms

Scientists have wrestled to understand why Huntington's disease, which is caused by a single gene mutation, can produce such variable symptoms. An authoritative review by a group of leading experts summarizes the progress relating cell loss in the striatum and cerebral cortex to symptom profile in Huntington's disease, suggesting a possible direction for developing targeted therapies.

Insect research yields insights for muscle control and nerve disorders in mammals

Working with fruit flies, Johns Hopkins scientists have decoded the activity of protein signals that let certain nerve cells know when and where to branch so that they reach and connect to their correct muscle targets. The proteins' mammalian counterparts are known to have signaling roles in immunity, nervous system and heart development, and tumor progression, suggesting broad implications for human disease research.

Researchers use electrokinetic patterning to separate particles and microbes by size

Researchers have demonstrated a new technology that combines a laser and electric fields to create tiny centrifuge-like whirlpools to separate particles and microbes by size, a potential lab-on-a-chip system for medicine and research.

Link between IRGM gene and composition of human gastrointestinal bacteria

New research led by the Karolinska Institutet, Sweden and the University of Glasgow, Scotland, has identified a link between a human gene and the composition of human gastrointestinal bacteria.

Scientists describe detailed structure and function of the TFIID protein complex

A research team of scientists from EMBL Grenoble and the IGBMC in Strasbourg, France, have, for the first time, described in molecular detail the architecture of the central scaffold of TFIID: the human protein complex essential for transcription from DNA to mRNA. The study, published today in Nature, opens new perspectives in the study of transcription and of the structure and mechanism of other large multi-protein assemblies involved in gene regulation.

Researchers identify protein that helps prevent obesity

University of Florida researchers and colleagues have identified a protein that, when absent, helps the body burn fat and prevents insulin resistance and obesity.

EHR implementation with technical support can improve patient care in small physician practices: Study

The relationship between a physician practice's adoption of electronic health records (EHR) and quality improvements in patient care remains unclear.

Newly discovered gene predicts HCV interferon response

Researchers have discovered a gene which interferes with the clearance of hepatitis C virus infection.

Edison Pharmaceuticals to commence EPI-743 phase 2B Friedreich's ataxia study

Edison Pharmaceuticals today announced the initiation of a phase 2B study entitled, "Safety and Efficacy Study of EPI-743 on Visual Function in Patients with Friedreich's Ataxia."

New research reveals a shared genetic susceptibility to epilepsy and migraine

New research reveals a shared genetic susceptibility to epilepsy and migraine. Findings published in Epilepsia, a journal of the International League Against Epilepsy (ILAE), indicate that having a strong family history of seizure disorders increases the chance of having migraine with aura (MA).

Researchers identify four new genetic regions associated with Behcet's disease

Researchers have identified four new regions on the human genome associated with Behcet's disease, a painful and potentially dangerous condition found predominantly in people with ancestors along the Silk Road.

PKM-zeta-less adult mice still able to form long-term memories

A study by Johns Hopkins researchers has shown that a widely accepted model of long-term memory formation - that it hinges on a single enzyme in the brain - is flawed. The new study, published in the Jan. 2 issue of Nature, found that mice lacking the enzyme that purportedly builds memory were in fact still able to form long-term memories as well as normal mice could.

Stanford scientists identify molecular basis for hypertrophic cardiomyopathy

When a young athlete dies unexpectedly on the basketball court or the football field, it's both shocking and tragic. Now Stanford University School of Medicine researchers have, for the first time, identified the molecular basis for a condition called hypertrophic cardiomyopathy that is the most common cause for this type of sudden cardiac death.

PSCA gene’s rs2294008 variant on T nucleotide may increase risk of bladder cancer

Patients who have inherited a specific common genetic variant develop bladder cancer tumors that strongly express a protein known as prostate stem cell antigen (PSCA), which is also expressed in many pancreatic and prostate tumors, according to research at the National Institutes of Health.

Chromatin regulation not governed by a uniform histone code

In a novel use of gene knockout technology, researchers at the University of California, San Diego School of Medicine tested the same gene inserted into 90 different locations in a yeast chromosome - and discovered that while the inserted gene never altered its surrounding chromatin landscape, differences in that immediate landscape measurably affected gene activity.

New insight into 22q11.2 deletion syndrome

Research out of the George Washington University (GW), published in the journal Proceedings of the National Academy of Sciences (PNAS), reveals another piece of the puzzle in a genetic developmental disorder that causes behavioral diseases such as autism.

New rat model simulates traumatic or surgical muscle tissue loss in humans

Penetrating soft tissue injuries that may be caused by bullet wounds or motor vehicle accidents, or exposure to explosive devices in military settings, can cause muscle loss resulting in functional disability and cosmetic deformity. Efforts underway to develop tissue engineering solutions to repair and replace damaged and lost muscle will benefit greatly from the availability of robust animal models to test these innovative therapeutic strategies.

Scientists discover process by which mda-9/syntenin contributes to melanoma metastasis

After recently announcing success in eliminating melanoma metastasis in laboratory experiments, scientists at Virginia Commonwealth University Massey Cancer Center have made another important discovery in understanding the process by which the gene mda-9/syntenin contributes to metastasis in melanoma (the spread of skin cancer) and possibly a variety of other cancers.

New technique can precisely add or delete genes in living cells

Researchers at MIT, the Broad Institute and Rockefeller University have developed a new technique for precisely altering the genomes of living cells by adding or deleting genes.

DRD4 7R allele can contribute to longevity

A variant of a gene associated with active personality traits in humans seems to also be involved with living a longer life, UC Irvine and other researchers have found.
