Scientists discover enzyme that acts as a 'fertility switch'

Scientists have discovered an enzyme that acts as a 'fertility switch', in a study published in Nature Medicine today. High levels of the protein are associated with infertility, while low levels make a woman more likely to have a miscarriage, the research has shown.

Reversing low VEGF levels may potentially treat patients with SCA1

A groundbreaking study in the journal Nature Medicine suggests what could become the first effective treatment for a debilitating and fatal disease of the central nervous system called SCA1.

Protein key to curbing overeating and preventing obesity

Including enough protein in our diets, rather than simply cutting calories, is the key to curbing appetites and preventing excessive consumption of fats and carbohydrates, a new study from the University of Sydney has found.

Molecular switch activates anti-viral innate immune response

When a thief breaks into a bank vault, sensors are activated and the alarm is raised. Cells have their own early-warning system for intruders, and scientists at the European Molecular Biology Laboratory (EMBL) in Grenoble, France, have discovered how a particular protein sounds that alarm when it detects invading viruses.

New research on link between APOL1 gene variants and kidney disease in African Americans

Compared to European Americans, African Americans are four to five times more likely to develop kidney failure. Also, family members of African Americans with kidney failure have an increased risk of developing kidney failure, which suggests that genetics may play a role in this skewed risk between races.

Exercise stimulates two beneficial proteins in women before and during pregnancy

Although exercise is generally considered to be a good thing for people with high blood pressure, it has traditionally been considered too risky for women who are also pregnant. Some studies suggest that exercise has benefits such as decreasing the risk of women developing preeclampsia, a condition that raises blood pressure to dangerously high levels but how this might happen has remained unknown.

Scientists uncover vast new gene regulatory network linked with cancer

Researchers at Columbia University Medical Center (CUMC) and two other institutions have uncovered a vast new gene regulatory network in mammalian cells that could explain genetic variability in cancer and other diseases.

Scientists reveal how resistance to hormone leptin develops

The effects of obesity - both on our bodies and on the health budget - are well known, and now, scientists are getting closer to understanding how the disease progresses, providing clues for future treatments.

Brain stem cell treatment for multiple sclerosis

The prospect of doing human clinical trials with stem cells to treat diseases like multiple sclerosis may be growing closer, say scientists at the University at Buffalo and the University at Rochester, who have developed a more precise way to isolate stem cells that will make myelin.

Lifestyle factors and nutritional patterns reduce early causes of childhood allergy

Today, about one in four European children suffer from allergy, which makes this disease the non-infectious epidemic of the 21st century. Evidence suggests that lifestyle factors and nutritional patterns, such as breastfeeding, help to reduce the early symptoms of allergy.

ApoPharma receives FDA approval for Ferriprox to treat transfusional iron overload

The U.S. Food and Drug Administration today approved Ferriprox (deferiprone) to treat patients with iron overload due to blood transfusions in patients with thalassemia, a genetic blood disorder that causes anemia, who had an inadequate response to prior chelation therapy.

Penn researchers demonstrate sound-processing deficits in mice brains with mutated dysbindin gene

Recent studies have identified many genes that may put people with schizophrenia at risk for the disease. But, what links genetic differences to changes in altered brain activity in schizophrenia is not clear. Now, three labs at the Perelman School of Medicine at the University of Pennsylvania have come together using electrophysiological, anatomical, and immunohistochemical approaches - along with a unique high-speed imaging technique - to understand how schizophrenia works at the cellular level.

Scientists characterize and isolate potential stem cells to treat MS, myelin disorders

Scientists have improved upon their own previous world-best efforts to pluck out just the right stem cells to address the brain problem at the core of multiple sclerosis and a large number of rare, fatal children's diseases.

Three-step strategy for healthy bones and strong muscles

For this year's World Osteoporosis Day, the International Osteoporosis Foundation (IOF) is releasing a 24-page report promoting a three-step strategy for healthy bones and strong muscles.

ESCs express genes linked with early germ cell specification

Ordinarily, embryonic stem cells exist only a day or two as they begin the formation of the embryo itself. Then they are gone. In the laboratory dish, however, they act more like perpetual stem cells - renewing themselves and exhibiting the ability to form cells of almost any type, a status called totipotency.

Study: Green vegetables boost immune function

Researchers reporting online in the journal Cell, a Cell Press publication, on October 13th have found another good reason to eat your green vegetables, although it may or may not win any arguments with kids at the dinner table.

Nature publishes Sangamo's gene correction strategy for A1AT deficiency

Sangamo BioSciences, Inc. (Nasdaq: SGMO) announced the publication of a preclinical study demonstrating highly specific, functional correction of the alpha 1-antitrypsin (A1AT) gene defect in patient-derived induced pluripotent stem cells (iPSCs) using zinc finger nucleases.

Survey analyses management of patients suffering from EGFRI toxicities

A recent survey of nurses from seven European countries, published in the peer-reviewed journal ecancermedicalscience, has analysed the management of patients suffering from toxicities due to treatment with epidermal growth factor receptor inhibitors.

BCL11A protein might serve as potential target for sickle cell disease

Flipping a single molecular switch can reverse illness in a model of sickle cell disease, according to a study by researchers at Children's Hospital Boston and Dana-Farber Cancer Institute. When turned off, the switch, a protein called BCL11A, allows the body to manufacture red blood cells with an alternate form of hemoglobin unaffected by the mutation that causes the disease.

Scientisits uncover evidence of powerful new cancer genetic networks

In findings with major implications for the genetics of cancer and human health, researchers at Beth Israel Deaconess Medical Center (BIDMC) and two other science teams in New York City and Rome have uncovered evidence of powerful new genetic networks and showed how it may work to drive cancer and normal development.
