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.

New platform for analysis of next generation sequencing data developed by Compugen

Compugen Ltd. (NASDAQ: CGEN) announced today the development of "NexGen," a new platform designed to significantly enhance Compugen’s overall infrastructure for predictive drug and drug target discovery. NexGen is designed to analyze Next Generation Sequencing data which is now beginning to be generated worldwide through RNA-Seq methodology.

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.

Association between SCC and cutaneous HPV types

Researchers at Moffitt Cancer Center and colleagues at the University of South Florida, the German Cancer Research Center in Heidelberg, and the International Agency for Research on Cancer in Lyon, France, conducted a case control study and found associations between having antibodies to certain types of cutaneous human papillomavirus (HPV) and a kind of skin cancer called squamous cell carcinoma (SCC).

Scientists use patient cells to generate human model of Huntington's

Scientists at the Gladstone Institutes and an international team of researchers have generated a human model of Huntington's disease-directly from the skin cells of patients with the disease.

Flu immunity depends on number of viruses involved during initial infection

Not only does the type of flu virus affect a patient's outcome, but a new research report appearing in the Journal of Leukocyte Biology suggests that the number of viruses involved in the initial infection may be important too.

New laboratory model for Huntington's disease

Cedars-Sinai scientists have joined with expert colleagues around the globe in using stem cells to develop a laboratory model for Huntington's disease, allowing researchers for the first time to test directly on human cells potential treatments for this fatal, inherited disorder.

Researchers probe origin of optimized antibodies against infections

An organism's ability to make new antibodies and use them to optimize its own immune defenses is of central importance in the fight against pathogens. In the case of severe infections, the overall relative speed with which an immune response proceeds could mean the difference between life and death.

Researchers create 'Huntington's disease in a dish' to enable search for treatment

Johns Hopkins researchers, working with an international consortium, say they have generated stem cells from skin cells from a person with a severe, early-onset form of Huntington's disease (HD), and turned them into neurons that degenerate just like those affected by the fatal inherited disorder.

Scientists identify abnormal gene that leads to Parkinson's

An international team including scientists from the University of Saskatchewan-Saskatoon Health Region and University of British Columbia, with the help of Saskatchewan Mennonite families, has identified an abnormal gene which leads to Parkinson's disease.

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.

Scientists now have clues to how GATA4 gene mutation leads to septal defects in babies with CHD

Scientists now have clues to how a gene mutation discovered in families affected with congenital heart disease leads to underdevelopment of the walls that separate the heart into four chambers.

New York Times examines bird flu studies, history of controversy

The New York Times examines several studies published in the journals Nature and Science looking at how the H5N1 bird flu virus could mutate to become more virulent among humans and outlines the history of controversy surrounding the studies.

Researchers identify latest gene associated with typical late-onset Lewy body Parkinson's

An international team led by human genetic researchers at the University of British Columbia and Vancouver Coastal Health has identified the latest gene associated with typical late-onset Lewy body Parkinson's disease (PD), with the help of a Canadian Mennonite family of Dutch-German-Russian ancestry.

Greater awareness of MH and consequences of ryanodine receptor gene mutations

From the MHAUS President's Blog by MHAUS President, Henry Rosenberg, MD. A few months ago, I received a call from the MH Hotline who connected me to an anesthesiologist and OR team who were desperately trying to manage a Malignant Hyperthermia crisis.

New drug better than chemotherapy for skin cancer patients

A new drug, dabrafenib, shows improvements over chemotherapy for patients suffering from a form of advanced skin cancer, according to the results of a Phase III study (“BREAK-3” trial) published Online First in the Lancet.

p53 protein may show a typical prion-like behavior when mutated

Prions, the causal agents of Mad Cow and other diseases, are very unique infectious particles. They are proteins in which the complex molecular three-dimensional folding process just went astray. For reasons not yet understood, the misfolding nature of prions is associated to their ability to sequester their normal counterparts and induce them to also adopt a misfolding conformation.
