Variable methylation predictive of age, gender, stress, cancer and early-life socioeconomic status

A Simon Fraser University physicist has helped discover that understanding how a chemical mark on our DNA affects gene expression could be as useful to scientists as fingerprints are to police at a crime scene.

Pioneering research paves way for new treatments for pulmonary arterial hypertension

Pioneering research conducted by the University of Sheffield is paving the way for new treatments which could benefit patients suffering from the fatal lung disease pulmonary arterial hypertension (PAH).

Chromosome 3p21.1 locus contains common genetic risk for bipolar disorder

One of the biggest challenges in psychiatric genetics has been to replicate findings across large studies. Scientists at King's College London, Institute of Psychiatry have now performed one of the largest ever genetic replication studies of bipolar affective disorder, with 28,000 subjects recruited from 36 different research centers. Their findings provide compelling evidence that the chromosome 3p21.1 locus contains a common genetic risk for bipolar disorder, the PBRM1 gene.

New insights into how brain responds to extreme stress

Researchers report new insights into how the brain responds to extreme stress, whether from combat, natural disasters, or repeated violent competition. The insights offer hope for detecting and treating several widespread and debilitating neuropsychiatric disorders, and were presented at Neuroscience 2012, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health.

UMass Amherst neuroscientist to receive 2012 Frank A. Beach Award from SBN

UMass Amherst neuroscientist Luke Remage-Healey will receive the 2012 Frank A. Beach Award from the Society for Behavioral Endocrinology for work showing exceptional promise and significant contributions in the field of behavioral neuroendocrinology. Named after a founder of the field, the award will be presented during the society's annual meeting this week in New Orleans. Remage-Healey will also give a lecture at the society's annual meeting next year.

Study helps uncover how brain processes and interprets facial expressions

Research released today helps reveal how human and primate brains process and interpret facial expressions, and the role of facial mimicry in everything from deciphering an unclear smile to establishing relationships of power and status.

Researchers identify keys and doors of Anaplasmataceae tick-borne bacterium

Virginia Commonwealth University School of Medicine researchers have identified the "keys" and "doors" of a bacterium responsible for a series of tick-transmitted diseases. These findings may point researchers toward the development of a single vaccine that protects against members of an entire family of bacteria that cause disease in humans, domestic animals and livestock.

Scientists take first steps to create neural-like stem cells from muscle tissue

Scientists at Wake Forest Baptist Medical Center have taken the first steps to create neural-like stem cells from muscle tissue in animals.

Scientists resolve new molecular circuit controlling cellular metabolism

Cancer, diabetes, and excess body weight have one thing in common: they alter cellular metabolism. Scientists from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and the Medical University of Vienna together with an international research team have jointly resolved a new molecular circuit controlling cellular metabolism.

Highlights of Mount Sinai research at Neuroscience 2012

Researchers from Mount Sinai School of Medicine are presenting important discoveries on the involvement of the immune system and dopamine cells in the onset of depression at Neuroscience 2012, the Society for Neuroscience's 42nd annual meeting on October 13 -17 in New Orleans, and are available for interviews.

Researchers identify molecular emergency brake in charge of regulating self-digestion

Almost everything that happens inside a cell, including autophagy, is tightly regulated on a biochemical level. Like that, the cell makes sure that processes only take place when they are needed and that they are shut off when the need has expired. "Inside the cell, there exists a network of molecules. Between them, information is constantly being exchanged," says Schmitz, head of the research group "Systems-oriented Immunology and Inflammation Research" at HZI, who also holds a chair at the Otto von Guericke University in Magdeburg.

Common genetic polymorphisms can increase risk of autism spectrum disorders

The causes of autism and autism spectrum disorder (ASD) are complex, and contain elements of both nature (genes) and the environment. New research published in BioMed Central's open access journal Molecular Autism shows that common genetic polymorphisms (genetic variation) can add up to an increased risk of ASD.

Researchers identify new genetic signature for sarcoidosis

Researchers at the University of Illinois Hospital & Health Sciences System have identified a genetic signature that distinguishes patients with complicated sarcoidosis, an inflammatory lung disease that can be fatal, from patients with a more benign form of the disease. The gene signature could become the basis for a simple blood test.

New insights into how miR-30d can promote healthy insulin production

Work by Michigan Technological University biologist Xiaoqing Tang is yielding new insights into how a tiny snippet of genetic material can promote healthy insulin production in mice.

Curcumin can inhibit formation of prostate cancer metastases

Powdered turmeric has been used for centuries to treat osteoarthritis and other illnesses. Its active ingredient, curcumin, inhibits inflammatory reactions. A new study led by a research team at Ludwig-Maximilians-Universit-t (LMU) in Munich now shows that it can also inhibit formation of metastases.

Scientists characterize unique model of bladder regeneration

While it is well known that starfish, zebrafish and salamanders can re-grow damaged limbs, scientists understand very little about the regenerative capabilities of mammals. Now, researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine report on the regenerative process that enables rats to re-grow their bladders within eight weeks.

Brown University, UCI researchers create Drosophila fruit fly model of epilepsy

In a newly reported set of experiments that show the value of a particularly precise but difficult genetic engineering technique, researchers at Brown University and the University of California-Irvine have created a Drosophila fruit fly model of epilepsy to discern the mechanism by which temperature-dependent seizures happen.

Novel method can determine how ready acute myeloid leukemia cells are to die

Researchers at Dana-Farber Cancer Institute have developed a novel method for determining how ready acute myeloid leukemia (AML) cells are to die, a discovery that may help cancer specialists to choose treatments option more effectively for their patients who have AML.

Study identifies 21 new gene variants associated with risks of heart disease, metabolic disorders

In the largest-ever genetic study of cholesterol and other blood lipids, an international consortium has identified 21 new gene variants associated with risks of heart disease and metabolic disorders.

Perception test could predict mild cognitive impairment

Psychologists at the University of Toronto and the Georgia Institute of Technology - commonly known as Georgia Tech - have shown that an individual's inability to recognize once-familiar faces and objects may have as much to do with difficulty perceiving their distinct features as it does with the capacity to recall from memory.
