Human stem cells effective in treating muscular dystrophy

Researchers from the University of Minnesota's Lillehei Heart Institute have effectively treated muscular dystrophy in mice using human stem cells derived from a new process that - for the first time - makes the production of human muscle cells from stem cells efficient and effective.

Malfunctioning single proteins cause disruptions in neuronal junctions leading to autism

Malfunctioning single proteins can cause disruptions in neuronal junctions leading to autistic forms of behavior. A current study, published in the scientific journal Nature, comes to this conclusion after examining genetically altered mice.

Novel stem cell transplantation holds promise for HIV prevention

UC Davis Health System researchers are a step closer to launching human clinical trials involving the use of an innovative stem cell therapy to fight the virus that causes AIDS.

FDA approves Protalix, Pfizer’s ELELYSO for treatment of type 1 Gaucher disease

Pfizer Inc. and Protalix BioTherapeutics, Inc. announced today that the United States (U.S.) Food and Drug Administration (FDA) approved ELELYSO (taliglucerase alfa) for injection, an enzyme replacement therapy (ERT) for the long-term treatment of adults with a confirmed diagnosis of type 1 Gaucher disease.

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.

Funders should follow lead of U.S. in creating policies for scientific research oversight

"The controversy over the research into the genetic modification of the H5N1 flu virus, finally approved for publication, should offer a reminder of the importance of debate" over dual-use technology, a Nature editorial states.

Heart can regulate energy balance throughout the body

UT Southwestern Medical Center researchers have demonstrated for the first time that the heart can regulate energy balance throughout the body, a finding that may point to more effective treatments for obesity, diabetes, and heart disease.

Exergames have significant benefits for older adults

Videogame technology is proving to be a valuable tool for helping people of all ages improve lifestyle and health habits and manage disease. New research is showing that exergames have significant benefits for older adults by providing cognitive stimulation and a source of social interaction, exercise, and fun.

Cancer therapy with common cold virus

Common viruses have become the latest weapon against cancer. There is the case of the eight-year-old African boy diagnosed with Burkitt's lymphoma at a Ugandan health clinic. He was exposed to the measles virus and in the next few weeks his tumour regressed completely and he entered remission. But only relatively recently have scientists clinically examined the interaction between viruses and cancers in the growing area of oncolytic virotherapy.

Researchers identify gene that increases risk of MI in newborns with CF

Researchers at Johns Hopkins have identified a gene that modifies the risk of newborns with cystic fibrosis (CF) developing neonatal intestinal obstruction, a potentially lethal complication of CF.

Beta cells from genetically modified pigs can effectively restore pancreas function

Transplantation of a whole pancreas or isolated insulin-producing beta cells are the only therapy to cure type 1 diabetes. However, the shortage of organ donors limits this approach to only few patients. LMU researchers have now shown that beta cells from genetically modified pigs can effectively restore pancreas function and can protect porcine beta cells from immune rejection in animal models.

Scientists discover tumor-targeting neural stem cells

Could engineered human stem cells hold the key to cancer survival? Scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have discovered that neural stem cells possess the innate ability to target tumor cells outside the central nervous system. This finding, which was demonstrated successfully on breast cancer cells, was recently published in leading peer reviewed journal, Stem Cells.

New evidence helps explain additional health benefits of aspirin

New evidence is helping explain additional health benefits of aspirin. Researchers in Canada, Scotland and Australia have discovered that salicylate, the active ingredient in aspirin, directly increases the activity of the protein AMPK (AMP-activated protein kinase), a key player in regulating cell growth and metabolism. AMPK which is considered a cellular fuel-gauge is switched on by exercise and the commonly used anti-diabetic medication metformin.

Chinese scientists make significant breakthrough in animal cloning

Chinese scientists from BGI, the world's largest genomics organization, together with the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences (CAS), and Shihezi University, Xinjiang province, made a significant breakthrough in animal cloning.

First specific antidote for cocaine toxicity

Scientists at The Scripps Research Institute have shown that an injectable solution can protect mice from an otherwise lethal overdose of cocaine. The findings could lead to human clinical trials of a treatment designed to reverse the effects of cocaine in case of emergency. Cocaine is involved in more than 400,000 emergency-room visits and about 5,000 overdose deaths each year in the United States.

Genetically modified mouse mimics key features of Charcot-Marie-Tooth disease

A team of scientists from the University of Missouri created a genetically modified mouse that mimics key features of Charcot-Marie-Tooth disease, an inherited neuromuscular disease affecting approximately 150,000 people in the United States.

Genetically modified mosquitoes offer hope of malaria eradication amid growing drug resistance

"In recent weeks, the emergence on the Thai-Myanmar border of malaria strains resistant to artemisinin, a plant-derived drug, have led to pessimistic headlines and reminders of the setback caused by resistance to the drug chloroquine, which began in the 1950s," columnist and author Matt Ridley writes in the Wall Street Journal's "Mind & Matter," noting, "April 25 is World Malaria Day, designed to draw attention to the planet's biggest infectious killer."

Steroids still work better for patients with sciatica

Despite the great promise that injecting a new type of anti-inflammatory pain medicine into the spine could relieve the severe leg and lower back pain of sciatica, a Johns Hopkins-led study has found that the current standard of care with steroid injections still does better.

Amyloid precursor protein appears to regulate its own production

A research team led by the University of South Florida Department of Psychiatry & Behavioral Neurosciences has found that a fragment of the amyloid precursor protein (APP) -- known as sAPP-α and associated with Alzheimer's disease -- appears to regulate its own production.
