Potential link between mutant huntingtin, cell loss and cell death in Huntington's disease

Using an in vitro cell model of Huntington's disease (HD), researchers at Florida Atlantic University's Charles E. Schmidt College of Medicine have discovered a novel mechanism and potential link between mutant huntingtin, cell loss and cell death or apoptosis in the brain, which is responsible for the devastating effects of this disease. Apoptosis has been proposed as one of the mechanisms leading to neuronal death in HD.

Safer alternative to experimental gene therapy against HIV infection

Scientists at The Scripps Research Institute have discovered a surprisingly simple and safe method to disrupt specific genes within cells. The scientists highlighted the medical potential of the new technique by demonstrating its use as a safer alternative to an experimental gene therapy against HIV infection.

Blocking AXL protein may prevent resistance to lung cancer drug

People with lung cancer who are treated with the drug Tarceva face a daunting uncertainty: although their tumors may initially shrink, it's not a question of whether their cancer will return—it's a question of when. And for far too many, it happens far too soon.

Early brain changes predict chances of developing chronic pain

When people have similar injuries, why do some end up with chronic pain while others recover and are pain free? The first longitudinal brain imaging study to track participants with a new back injury has found the chronic pain is all in their heads -- quite literally.

Genetic mutation that creates Ewing's sarcoma leads to high levels of protein EYA3

Ewing's sarcoma is a bone cancer commonly diagnosed in about 250 U.S. teenagers per year. If early chemotherapy is effective, improvement can be durable. But for children and teens who respond poorly to a first attempt at chemotherapy or if the disease spreads, long-term survival can be less than 10 percent.

Study details canonical Wnt signaling pathway

Many lung cancers are driven by mutations in the epidermal growth-factor receptor (EGFR), and so it makes sense that many successful modern treatments block EGFR activity. Unfortunately, cancers inevitably evolve around EGFR inhibition, and patients with lung cancers eventually relapse.

Researchers discover new gene mutations associated with megalencephaly

A research team led by Seattle Children's Research Institute has discovered new gene mutations associated with markedly enlarged brain size, or megalencephaly.

Researchers identify genes that influence degeneration of the hippocampus

In a genome-wide association (GWA) study, researchers from Boston University Schools of Medicine (BUSM) and Public Health (BUSPH) have identified several genes which influence degeneration of the hippocampus, the part of the brain most associated with Alzheimer disease (AD).

Scientists transplant stem cells from patients with limb-girdle muscular dystrophy into mice

Stem cells from patients with a rare form of muscular dystrophy have been successfully transplanted into mice affected by the same form of dystrophy, according to a new study published today in Science Translational Medicine.

New compound could treat certain types of genetic disorders in muscles

Scientists at UCLA have identified a new compound that could treat certain types of genetic disorders in muscles. It is a big first step in what they hope will lead to human clinical trials for Duchenne muscular dystrophy.

Study suggests adverse role for BclI polymorphism in obesity and insulin resistance

A large study in people at risk of diabetes has found a direct association between the presence of a small genetic alteration in a hormone receptor and increased body fat and insulin resistance. The results, to be presented Tuesday at The Endocrine Society's 94th Annual Meeting in Houston, suggest an adverse role for a previously described genetic variant, the BclI polymorphism.

Registry proves invaluable for fibromuscular dysplasia patients

A patient registry is proving invaluable in cataloging the clinical features, symptoms, severity, and outcomes of fibromuscular dysplasia (FMD), a non-inflammatory vascular disease that can cause narrowing of arteries in the carotid (neck) and renal (kidney) arteries, which can result in headache, strokes, and aneurysms.
