Three new gene variants associated with BMI levels in adults

A large international study has identified three new gene variants associated with body mass index (BMI) levels in adults. The scientific consortium, numbering approximately 200 researchers, performed a meta-analysis of 46 studies, covering gene data from nearly 109,000 adults, spanning four ethnic groups.

UC Riverside entomologists reconstruct the evolutionary history of assassin bugs

Assassin bugs, so named because these insects lie in ambush for prey that they attack with speed and precision, are found all over the world. Nearly 140 species of these bugs are blood-sucking; because they can bite humans around the mouth, they are also called kissing bugs. All kissing bugs can spread Chagas disease, a neglected tropical disease that imposes an economic burden on society.

NetBio to present ANDE system at 2012 IEEE homeland security conference

Current DNA analysis methods require expert users in a controlled laboratory environment and take weeks to months to produce results. The ANDE system from NetBio would allow the generation of CODIS-quality DNA profiles by non-technical users in a field environment in less than 1.5 hours.

Aspirin therapy can extend life of colorectal cancer patients with PIK3CA mutation

Aspirin therapy can extend the life of colorectal cancer patients whose tumors carry a mutation in a key gene, but has no effect on patients who lack the mutation, Dana-Farber Cancer Institute scientists report in the Oct. 25 issue of the New England Journal of Medicine.

Study indicates that Firemaster 550 is an endocrine disruptor

The flame-retardant mixture known as "Firemaster 550" is an endocrine disruptor that causes extreme weight gain, early onset of puberty and cardiovascular health effects in lab animals, according to a new study spearheaded by researchers from North Carolina State University and Duke University.

Pomc gene can be turned on and off in a mouse model of obesity

Obesity is a chronic metabolic disorder that affects half a billion people worldwide. Managing obesity is difficult, as many patients rebound to their pre-treatment weight. There is a hypothesis that chronic weight gain causes the body to adopt a state that supports excess weight.

Study confirms Elf5 protein as tumor suppressor of breast cancer

A protein that is necessary for lactation in mammals inhibits the critical cellular transition that is an early indicator of breast cancer and metastasis, according to research conducted at the University at Buffalo and Princeton University and highlighted as the cover paper in November issue of Nature Cell Biology.

New findings on how OX40 activation affects T helper cells that target melanoma

Cancers arise in the body all the time. Most are nipped in the bud by the immune response, not least by its T cells, which detect telltale molecular markers-or antigens-on cancer cells and destroy them before they grow into tumors. Cancer cells, for their part, evolve constantly to evade such assassination. Those that succeed become full-blown malignancies. Yet, given the right sort of help, the immune system can destroy even these entrenched tumors.

Study sheds light on why the weight inevitably comes back

Joint research between the University of Michigan and the Argentina-based National Council of Science and Technology (CONICET) has shed light on one of the most frustrating mysteries of weight loss - why the weight inevitably comes back.

Vascular endothelial cells play a larger role in pulmonary hypertension

It turns out the muscle cells on the outside of blood vessels have been wrongly accused for instigating lung disease. New research shows that while these muscle cells are responsible for constricting or dilating the blood vessels, they are not responsible for sensing the amount of oxygen that gets to the lungs. That message comes from the endothelial cells - special cells that line the blood vessels - along a "signalling pathway."
