The Influence Of Genes On Psychological Well-Being
Genes play a greater role in forming character traits - such as self-control, decision making or sociability - than was previously thought, new research suggests. A study of more than 800 sets of twins found that genetics were more influential in shaping key traits than a person's home environment and surroundings...

Women At Risk Of Post Natal Depression May Be Identified By Blood Test
Researchers at Warwick Medical School have discovered a way of identifying which women are most at risk of postnatal depression (PND) by checking for specific genetic variants. The findings could lead to the development of a simple, accurate blood test which checks for the likelihood of developing the condition...

Gene Related To Autism, Schizophrenia And Obesity Isolated By Zebrafish Study
What can a fish tell us about human brain development? Researchers at Duke University Medical Center transplanted a set of human genes into a zebrafish and then used it to identify genes responsible for head size at birth. Researchers at Duke University Medical Center transplanted a set of human genes into a zebrafish and then used it to identify genes responsible for head size at birth...

New Clues On How ApoE4 Affects Alzheimer's Risk
Common variants of the ApoE gene are strongly associated with the risk of developing late-onset Alzheimer's disease, but the gene's role in the disease has been unclear. Now, researchers funded by the National Institutes of Health have found that in mice, having the most risky variant of ApoE damages the blood vessels that feed the brain...

More Genes Discovered In The Fight Against Breast Cancer
In a study published in Nature, researchers describe nine new genes that drive the development of breast cancer. This takes the tally of all genes associated with breast cancer development to 40. The team examined all the genes in the genomes of 100 cases of breast cancer...

Groundbreaking Advance In Medical Diagnostics
Researchers have created an ultrasensitive biosensor that could open up new opportunities for early detection of cancer and "personalized medicine" tailored to the specific biochemistry of individual patients. The device, which could be several hundred times more sensitive than other biosensors, combines the attributes of two distinctly different types of sensors, said Muhammad A...

Insight Into Brain Regeneration And Developmental Disorders From Mice With Big Brains
Scientists at the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa (uOttawa) have discovered that mice that lack a gene called Snf2l have brains that are 35 per cent larger than normal. The research, led by Dr...

Using Antioxidants To Stabilize Fanconi Anemia
Fanconi anemia (FA) is a rare genetic disorder which affects one person in 350,000. People affected by this disease have defects in DNA repair, and are hypersensitive to oxidative damage, resulting in bone marrow failure and an increased predisposition to cancer...

New Mechanism For Anxiety Disorders Revealed By Mystery Gene
A novel mechanism for anxiety behaviors, including a previously unrecognized inhibitory brain signal, may inspire new strategies for treating psychiatric disorders, University of Chicago researchers report. By testing the controversial role of a gene called Glo1 in anxiety, scientists uncovered a new inhibitory factor in the brain: the metabolic by-product methylglyoxal...

Possible Diagnostic Technique For Lung Cancer Screening
The most recent research released in June's Journal of Thoracic Oncology says molecular biomarkers in the tissue and fluid lining the lungs might be an additional predictive technique for lung cancer screening. Since the National Lung Screening Trial found that 96...

Key Genes And Prototype Predictive Test Identified For Schizophrenia
An Indiana University-led research team, along with a group of national and international collaborators, has identified and prioritized a comprehensive group of genes most associated with schizophrenia that together can generate a score indicating whether an individual is at higher or lower risk of developing the disease...

Potential To Treat Arthritis Using Delivery System For Gene Therapy
A DNA-covered submicroscopic bead used to deliver genes or drugs directly into cells to treat disease appears to have therapeutic value just by showing up, researchers report. Within a few hours of injecting empty-handed DNA nanoparticles, Georgia Health Sciences University researchers were surprised to see increased expression of an enzyme that calms the immune response...

Gene Variants Identified That Speed Progression Of Parkinson's Disease
UCLA researchers may have found a key to determining which Parkinson's disease patients will experience a more rapid decline in motor function, sparking hopes for the development of new therapies and helping identify those who could benefit most from early intervention...

Discovery Of New Gene Mutations Leads To Breakthrough In Understanding The Cause Of Bile Duct Cancer
A team of international scientists has made a significant breakthrough in understanding the cause of bile duct cancer, a deadly type of liver cancer. By identifying several new genes frequently mutated in bile duct cancers, researchers are paving the way for better understanding of how bile duct cancers develop. Their discovery is published online in Nature Genetics...

Eye Cancer Tumors Likely To Spread Can Be Identified By Genetic Test
Researchers at Washington University School of Medicine in St. Louis have developed a genetic test that can accurately predict whether the most common form of eye cancer will spread to other parts of the body, particularly the liver...
