Study provides new information on why A-T disease attacks the brain

Rutgers scientists think they have found a way to prevent and possibly reverse the most debilitating symptoms of a rare, progressive childhood degenerative disease that leaves children with slurred speech, unable to walk, and in a wheelchair before they reach adolescence.

STAT-1 and PLSCR-1 proteins could play a crucial role in breast cancer

At the time of diagnosis, the majority of breast cancers are categorized as estrogen-receptor positive, or hormone sensitive, which means their cancerous cells may need estrogen to grow. Patients with this type of cancer often respond favorably to treatments called aromatase inhibitors, like tamoxifen, which cause cell death by preventing estrogen from reaching the cancerous cells.

Study shows how fat cells can protect the body against diabetes

In a finding that may challenge popular notions of body fat and health, researchers at Beth Israel Deaconess Medical Center (BIDMC) have shown how fat cells can protect the body against diabetes. The results may lead to a new therapeutic strategy for preventing and treating type 2 diabetes and obesity-related metabolic diseases, the authors say.

Aberrations in translation regulators linked with hormone receptor-positive breast cancer survival

Four proteins involved in translation, the final step of general protein production, are associated with poor prognosis in hormone-receptor-positive breast cancer when they are dysregulated, researchers reported at the AACR Annual Meeting 2012.

Study uses simple technique to break military camouflage

Researchers want to help the Army better camouflage its soldiers and break the enemy's efforts to hide. "We want to make our camouflage unbreakable and we want to break the camouflage of the enemy," said Dr. Jay Hegde, neuroscientist in the Medical College of Georgia at Georgia Health Sciences University.

Thermally content mice might serve as meaningful research subjects

Nine out of 10 drugs successfully tested in mice and other animal models ultimately fail to work in people, and one reason may be traced back to a common fact of life for laboratory mice: they're cold, according to a researcher at the Stanford University School of Medicine.

Diversity of intestinal stem cells is greater than previously thought

Tales from the crypt are supposed to be scary, but new research from Vanderbilt University, the HudsonAlpha Institute for Biotechnology and colleagues shows that crypts can be places of renewal too: intestinal crypts, that is. Intestinal crypts are small areas of the intestine where new cells are formed to continuously renew the digestive tract. By focusing on one protein expressed in our intestines called Lrig1, the researchers have identified a special population of intestinal stem cells that respond to damage and help to prevent cancer.

New project to focus on role of Myc oncoproteins in B-cell lymphoma

The National Institutes of Health has awarded The Scripps Research Institute $2 million to study the role of a pathway in the development and maintenance of B-cell lymphoma, a type of cancer that begins in immune system and turns normal disease fighting cells into cancers. The disease affects immune cells known as lymphocytes, which are part of our white blood cells.

Clinical findings from Transgenomic's NuclearMitome Test study on nuclear mitochondrial disorders

Transgenomic, Inc. today announced that Jeana DaRe, Ph.D., Assistant CLIA Laboratory Director at Transgenomic, presented clinical findings from patients tested for nuclear mitochondrial disorders using Transgenomic's NuclearMitome Test on Thursday, March 29, at the 2012 Annual Meeting of the American College of Medical Genetics (ACMG) in Charlotte, North Carolina.

Dengue infection makes mosquito's blood feeding more efficient

Mosquitoes infected with dengue virus experience an array of changes in the activity of genes and associated functions of their salivary glands, and these changes may lead to increased virus transmission, according to a recent study led by George Dimopoulos, Ph.D., of the Malaria Research Institute and Bloomberg School of Public Health at Johns Hopkins University.

UH clinical trial to evaluate stool DNA testing for colon cancer

In a first-of-its-kind clinical trial, physician-scientists at University Hospitals (UH) Case Medical Center's Seidman Cancer Center and Case Western Reserve University School of Medicine are studying a promising new non-invasive technology for colon cancer screening. The four-year study is recruiting patients to compare the effectiveness of stool DNA (SDNA) testing with colonoscopy for detecting large colon polyps.

SAP protein promotes deposition of amyloid beta in Alzheimer's

The deposition of amyloid beta in the brain of individuals with Alzheimer's disease is the focus of much research into both its cause and treatment.

Nmnat enzyme plays a critical role in nerve injury

A new animal model of nerve injury has brought to light a critical role of an enzyme called Nmnat in nerve fiber maintenance and neuroprotection.

BPA shows tangible effects on health endpoints at high dosage levels

Endocrine-disrupting chemicals (EDCs)-such as BPA-can show tangible effects on health endpoints at high dosage levels, yet those effects do not predict how EDCs will affect the endocrine system at low doses, according to a recent study accepted for publication in The Endocrine Society's Endocrine Reviews.

Disrupting mTORC1 protein complex extends lifespan

One of the secrets to a longer, healthier life is simply to eat less. When subjected to calorie restriction (CR), typically defined as a 20-40% reduction in caloric intake with corresponding maintenance of proper nutrition, animals in labs not only live longer, but also have improved insulin sensitivity and glucose tolerance, both of which decline during aging.

Study confirms innate ability of ticks to adapt to changing climatic conditions

Carnivores in the Iberian Peninsula, such as the Iberian lynx, are under an increasingly serious threat: ticks that can adapt to changing climatic conditions and that can even survive in extremely arid environments. A study headed by Spanish researchers confirms the innate ability of ticks to adapt according to climate.

Infection with dengue virus turns on feeding-related genes in mosquitoes

Researchers at the Johns Hopkins Bloomberg School of Public Health have, for the first time, shown that infection with dengue virus turns on mosquito genes that makes them hungrier and better feeders, and therefore possibly more likely to spread the disease to humans.

Cancer cells grow and proliferate more robustly when exposed to human cells

New research from the Technion-Israel Institute of Technology Rappaport Faculty of Medicine and Research Institute and the Rambam Medical Center may lead to the development of new methods for controlling the growth of cancer, and perhaps lead to treatments that will transform cancer from a lethal disease to a chronic, manageable one, similar to AIDS.
