Childhood adversity may lead to epigenetic changes in glucocorticoid receptor gene

In a look at how major stressors during childhood can change a person's biological risk for psychiatric disorders, researchers at Butler Hospital have discovered a genetic alteration at the root of the association.

The high cost of cancer care

Forty years after the National Cancer Act launched the "war on cancer," the battle is not just finding cures and better treatments but also being able to afford them. New drugs often cost $100,000 or more a year. Patients are being put on them sooner in the course of their illness and for a longer time -; sometimes for the rest of their lives.

LA BioMed to honor Women & Infants physician as 'Legend'

The Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed) recently announced that it will honor John E. Buster, MD, associate director of the Center for Reproduction and Infertility at Women & Infants Hospital of Rhode Island and Tufts Medical Center, as one of its three "Legends" this May.

New RNA interference method holds promise for cancer, other diseases

For the past decade, scientists have been pursuing cancer treatments based on RNA interference - a phenomenon that offers a way to shut off malfunctioning genes with short snippets of RNA. However, one huge challenge remains: finding a way to efficiently deliver the RNA.

Death of myelin sheath producing cells does not trigger MS

Millions of adults suffer from the incurable disease multiple sclerosis (MS). It is relatively certain that MS is an autoimmune disease in which the body's own defense cells attack the myelin in the brain and spinal cord.

Montefiore director to host Twitter chat about neuroendocrine tumors on Feb. 29

On February 29, which is Rare Disease Day, Steven Libutti, MD, Vice Chairman of Surgery and Director of the Montefiore Einstein Center for Cancer Care will host a Twitter chat about the signs and symptoms, diagnosis and treatment of neuroendocrine tumors, or NETs, a rare form of cancer.

MGH scientists isolate OSCs from ovaries of reproductive age women

For the first time, Massachusetts General Hospital (MGH) researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and shown these cells can produce what appear to be normal egg cells or oocytes.

News briefs from featured presentations at Cardiology 2012

Pediatric cardiology researchers and clinicians from almost 50 centers from across the U.S. and around the world are gathering at the Cardiology 2012 Conference sponsored by The Children's Hospital of Philadelphia on Feb. 22-26 in Orlando, Fla.

Cabozantinib blocks c-MET and VEGF signaling in mouse model of pancreatic cancer

Dual inhibition of vascular endothelial growth factor and c-MET signaling inhibited tumor invasion and metastasis in a laboratory model of pancreatic neuroendocrine cancer, according to a paper published in Cancer Discovery, the newest journal of the American Association for Cancer Research.

Researchers identify elusive gene responsible for TAR syndrome

Researchers have identified an elusive gene responsible for Thrombocytopenia with Absent Radii (TAR), a rare inherited blood and skeletal disorder. As a result, this research is now being transformed into a medical test that allows prenatal diagnosis and genetic counselling in affected families.

Study finds genetic variants that elevate risk for skin lesions in people exposed to arsenic

One of the first large-scale genomic studies conducted in a developing country has discovered genetic variants that elevate the risk for skin lesions in people chronically exposed to arsenic. Genetic changes found near the enzyme for metabolizing the chemical into a less toxic form can significantly increase an individual's risk for developing arsenic-related disease.

Lung function, obstructive airway diseases linked with increased risk of heart failure

A large population-based study has found that lung function and obstructive airway diseases are strongly and independently associated with increased risk of heart failure. Importantly, say the investigators, this association was even evident in never-smokers and was still evident after adjustment for smoking status and number of years smoking. This, they add, indicates "that our results are not primarily confounded by smoking".

Skin cancer drug may prolong survival in advanced cases: Study

Researchers say 132 patients in the U.S. and Australia who were given the drug vemurafenib gained several extra months of life. The study published in the New England Journal of Medicine found that those on the drug lived an average of 16 months, compared with nine months on conventional treatment.

Seven scientists aim to make strides in predicting and preventing preterm birth

With the help of funding from the March of Dimes, researchers from five states and Canada are seeking answers to questions such as how cellular-level processes that control uterine muscles may affect preterm labor, the causes of preeclampsia, and how air pollution may affect pregnancy and preterm birth - all with the goal of preventing preterm birth so more babies will get a healthy start in life.

Evolutionary forces encourage diversity in the active surfaces of venomous toxins

For snakes, spiders, and other venomous creatures, the "business end," or active part, of a toxin is the area on the surface of a protein that is most likely to undergo rapid evolution in response to environmental constraints, say researchers from Ben Gurion University in Israel.

UA researchers identify the likely culprit of epilepsy

Only 10 years ago, deciphering the genetic information from one individual in a matter of weeks to find a certain disease-causing genetic mutation would have been written off as science fiction. It was the time of the Human Genome Project, and it had taken armies of sequencing robots working around the clock for almost a decade to unravel the complete sequence of the human genetic code - referred to as the genome - by churning out the DNA alphabet letter by letter.

Scientists decode two new blood types

You probably know your blood type: A, B, AB or O. You may even know if you're Rhesus positive or negative. But how about the Langereis blood type? Or the Junior blood type? Positive or negative? Most people have never even heard of these.

Children of immigrant parents more likely to develop autism with intellectual disability

A major register study from the Swedish medical university Karolinska Institutet shows that children born to certain groups of immigrants in Sweden had an increased risk of developing autism with intellectual disability. The study includes all children in Stockholm County from 2001 to 2007, and brings the question of the heredity of autism to the fore.

FSU receives NIH grant to better understand and diagnose dyslexia

If you can read this sentence with ease, consider yourself fortunate: Millions of Americans with dyslexia cannot. In the hope of improving the lives of those struggling readers, a team of experts at Florida State University is working to better understand and diagnose dyslexia and other learning disabilities with a new, $8.5 million grant from the National Institutes of Health.
