Loss of estrogen receptor alpha protein may lead to metabolic syndrome

UCLA researchers demonstrated that loss of a key protein that regulates estrogen and immune activity in the body could lead to aspects of metabolic syndrome, a combination of conditions that can cause Type 2 diabetes, atherosclerosis and cancer. Called estrogen receptor alpha, this protein is critical in regulating immune system activity such as helping cells suppress inflammation and gobble-up debris.

Human brain places more value on winning in a social setting

A new USC study explains why people take stupid chances when all of their friends are watching that they would never take by themselves. According to the study, the human brain places more value on winning in a social setting than it does on winning when you're alone.

Scientists discover 29 new genetic variants linked with MS

Multiple sclerosis is primarily an immunological disease. Scientists at Charité - Universitätsmedizin Berlin and Max-Delbrück-Center for Molecular Medicine (MDC) have in succeeded, in collaboration with 23 research teams from 15 different countries, in discovering a total of 29 new genetic variants that are involved in the genesis of multiple sclerosis (MS), an inflammatory disease of the nervous system.

International researchers to assess role of pre-clinical animal models in drug discovery

The New York Academy of Sciences and the Global Medical Excellence Cluster (GMEC), in collaboration with Imperial College London and King's College London, will host a two-day scientific conference, "Animal Models and Their Value in Predicting Drug Efficacy and Toxicity," that will provide a forum to critically examine the role of pre-clinical animal models in drug discovery.

Glioma stem cells can change their metabolic state at will, finds study

The metabolic state of glioma stem cells, which give rise to deadly glioblastomas, is significantly different from that of the brain cancer cells to which they give birth, a factor which helps those stem cells avoid treatment and cause recurrence later.

Scientists discover two opposing neuronal regulatory circuits for generation, elimination of fear

Emotional balance is regulated by molecular factors behind stress response. When healthy people are faced with threatening situations, they react with a suitable behavioural response and do not descend into a state of either panic or indifference, as is the case, for example, with patients who suffer from anxiety.

Study on effects of adult stem cell treatments in patients with Hereditary Ataxia

The Journal of Translational Medicine reports on a new study in which 30 patients with Hereditary Ataxia showed statistically significant improvements in functionality and quality of life after being treated with a combination of cord blood-derived stem cell treatments and physical therapy.

Researchers discover new genetic defect that can lead to Leigh syndrome

In Leigh syndrome, infants are born apparently healthy only to develop movement and breathing disorders that worsen over time, often leading to death by the age of 3. The problem is that the mitochondria responsible for powering their cells can't keep up with the demand for energy in their developing brains.

Pancreatic mesenchyme plays central role in the formation of mature beta cells

A somewhat mysterious soft tissue found in the fetus during early development in the womb plays a pivotal role in the formation of mature beta cells the sole source of the body's insulin. This discovery, made by scientists at University of California, San Francisco (UCSF) and Texas A&M University, may lead to new ways of addressing Type 1 and Type 2 diabetes.

Scientists uncover new ways to stimulate pancreatic beta cell growth

One of the holy grails in diabetes research is to discover molecules that stimulate beta cell growth and to find drugs that target these molecules. Now, JDRF-funded researchers in collaboration with the pharmaceutical company Hoffmann-La Roche, have done both, discovering not only a protein that regulates beta cell growth, but also a chemical compound that stimulates it.

Study: K-complexes control effects of noise on sleep

During sleep, our perception of the environment decreases. However the extent to which the human brain responds to surrounding noises during sleep remains unclear. In a study published this week in Proceedings of the National Academy of Sciences (PNAS), researchers from University of Liège used brain imaging to study responses to sounds during sleep.

Breast cancer patients with BRCA1 mutation experience pCR after neoadjuvent chemotherapy

Nearly half of breast cancer patients carrying the BRCA1 gene mutation experience a complete pathological response (pCR) - the disappearance of all evidence of disease from the breast tissue and lymph nodes - regardless of disease stage after standard neoadjuvent chemotherapy, according to new research from The University of Texas MD Anderson Cancer Center.
