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.

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.

Needle-free vaccine shows promise against RSV in children

Researchers at the University of Saskatchewan are closing in on a needle-free vaccine for respiratory syncytial virus (RSV), a major cause of respiratory illness in children under two years of age.

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.

TRIM28 protein essential after fertilisation to preserve epigenetic marks on imprinted genes

An international team led by scientists at A*STAR's Institute of Medical Biology (IMB) discovered that a protein, called TRIM28, normally present in the mother's egg, is essential right after fertilisation, to preserve certain chemical modifications or 'epigenetic marks' on a specific set of genes.

Vitamin D-fortified doogh improves inflammatory markers in type 2 diabetics

Daily intake of vitamin D-fortified doogh (Persian yogurt drink) improved inflammatory markers in type 2 diabetics and extra calcium conferred additional anti-inflammatory benefits, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism.

Researchers identify new population of intestinal stem cells

Vanderbilt-Ingram Cancer Center researchers have identified a new population of intestinal stem cells that may hold clues to the origin of colorectal cancer.

Researchers discover MicroRNAs as new switch of adipose cell development

Hunger has always threatened mankind. This makes it unsurprising that human bodies attempt to store all surplus nourishment in adipose tissue. In developed countries, this life-saving craving is turning into a problem and obesity—adiposity—is turning into a danger. Why, though, does excess fat the body ill? How does fat trigger diabetes? And can these superfluous fat reserves be turned into warmth and just as well burnt?

Study explains how rapamycin also causes insulin resistance

A Penn- and MIT-led team explained how rapamycin, a drug that extends mouse lifespan, also causes insulin resistance. The researchers showed in an animal model that they could, in principle, separate the effects, which depend on inhibiting two protein complexes, mTORC1 and mTORC2, respectively.

XRCC2 gene mutations cause increased breast cancer risk

Mutations in a gene called XRCC2 cause increased breast cancer risk, according to a study published today in the American Journal of Human Genetics. The study looked at families that have a history of the disease but do not have mutations in the currently known breast cancer susceptibility genes.

Albumin best choice for prevention of circulatory dysfunction in cirrhotic patients

Administration of albumin reduces morbidity and mortality in cirrhotic patients undergoing large-volume paracentesis due to severe ascites, according to a new meta-analysis published online today in Hepatology, the official journal of the American Association for the Study of Liver Diseases.

Ember adds Joslin's BMP7 technology to brown fat intellectual property portfolio

Ember Therapeutics, Inc., a company harnessing breakthroughs in brown fat biology and insulin sensitization to revolutionize the treatment of metabolic disease, today announced the completion of an agreement with the Joslin Diabetes Center to exclusively license intellectual property covering bone morphogenetic protein 7 (BMP7), which has been shown to play a role in the regulation of brown fat development.

Biochemists determine atomic structure of new ABC transporter

Proteins belonging to the large and important family of ABC transporters have been associated with metabolic diseases and can cause resistance to antibiotics. Biochemists from the University of Zurich and the NCCR Structural Biology have succeeded in determining the atomic structure of a new ABC transporter. The insights gained could give rise to new therapies to treat multi-resistant bacteria, cystic fibrosis or gout, for instance.

Ember, Joslin aims to utilize brown fat for treatment of obesity and diabetes

Joslin Diabetes Center and Ember Therapeutics, Inc. today announced an agreement aimed at utilizing "brown fat," a type of fat that helps increase energy expenditure within the body, as a novel technique for managing obesity and diabetes. Joslin's Chief Academic Officer, Dr. Ronald Kahn and other Joslin faculty, Drs. Yu-Hua Tseng and Aaron Cypess, have performed pioneering work in this field over the past several years, and were the first to show that a natural protein called BMP7 can help modulate the levels of brown fat.

New treatment approach halts spread of cancer cells into normal brain tissue

Treating invasive brain tumors with a combination of chemotherapy and radiation has improved clinical outcomes, but few patients survive longer than two years after diagnosis. The effectiveness of the treatment is limited by the tumor's aggressive invasion of healthy brain tissue, which restricts chemotherapy access to the cancer cells and complicates surgical removal of the tumor.

Researchers design new treatment approach for invasive brain tumors

Researchers from Emory and the Georgia Institute of Technology have designed a new treatment approach that appears to halt the spread of cancer cells into normal brain tissue in animal models.

Researchers describe unexpected role of p75NTR in type 2 diabetes

Scientists at the Gladstone Institutes have discovered a key protein that regulates insulin resistance-the diminished ability of cells to respond to the action of insulin and which sets the stage for the development of the most common form of diabetes. This breakthrough points to a new way to potentially treat or forestall type 2 diabetes, a rapidly growing global health problem.

Scientists explore number of strategies to prevent anesthesia-induced injury in infants

Recent clinical studies have shown that general anesthesia can be harmful to infants, presenting a dilemma for both doctors and parents. But new research at Wake Forest Baptist Medical Center may point the way to treatment options that protect very young children against the adverse effects of anesthesia.
