Low levels of vitamin D, methylation in black teens may increase cancer risk

Low levels of vitamin D in black teens correlates with low activity of a major mechanism for controlling gene expression that may increase their risk of cancer and other disease, researchers report.

New computer algorithm can better characterize functional context of genomic variations in cancer

Cancer is rarely the result of a single mutation in a single gene. Rather, tumors arise from the complex interplay between any number of mutually exclusive abnormal changes in the genome, the combinations of which can be unique to each individual patient.

Scientists discover underlying mechanisms of nerve damage

Recent research by Sandra Rieger, Ph.D., of the MDI Biological Laboratory identifying the underlying mechanisms of peripheral neuropathy, or nerve damage, has raised the prospect that drug therapies can be developed for the treatment of this condition, which causes pain, numbness and/or tingling in the hands and feet. The research was published March 28 in the Proceedings of the National Academy of Sciences.

Increased expression of VEGF-A promotes three common aging-related eye conditions

A Massachusetts General Hospital investigator has found that increased expression of the angiogenic factor VEGF-A promotes three common aging-related eye conditions - both versions of age-related macular degeneration (AMD) and also cataracts - in an animal model.

Novel metabolic pathways help cancer cells thrive under certain conditions

Scientists at the Children's Medical Center Research Institute at UT Southwestern (CRI) have identified a novel metabolic pathway that helps cancer cells thrive in conditions that are lethal to normal cells.

Aged tumor cells in melanoma behave in a different way than younger tumor cells

Cancer risk increases with one's age as accumulated damage to our cells and chronic inflammation occur over time. Now, an international team of scientists led by The Wistar Institute have shown that aged tumor cells in melanoma behave differently than younger tumor cells, according to study results published in the journal Nature.

Tumor suppressor p53 gene twice as likely to be defective in autistic children

A large study by researchers with the UC Davis MIND Institute has found that a gene whose role is to suppress cellular damage from environmental stressors is nearly twice as likely to be defective in children with autism spectrum disorder (ASD), and that the deficit is also present in their fathers.

New Rutgers study links protein that helps fight infection to heart and liver disease

A protein that should help fight infection and keep us healthy may be targeted for treating devastating illnesses like heart and liver disease, according to a new Rutgers study.

Long-term recreational football training improves health of older men

A new scientific study shows that long-term recreational football training produces a number of marked improvements in health profile for 63-75 year old untrained men -- including a reduced risk of developing cardiovascular diseases and diabetes.

Enhanced diet helps slow progression of hereditary deafness

An enhanced diet helped reduce hearing loss in mice with the genetic mutation most commonly responsible for childhood deafness, new research suggests.

Depression may be a systemic disease, say researchers

An international team of researchers lead by the University of Granada has scientifically proven, for the first time, that depression is associated with important alterations of the oxidative stress, so it should be considered a systemic disease.

Novel mitochondria-specific ceria nanoparticles can effectively suppress neuronal cell death

The brain is an enormous network of communication, containing over 100 billion nerve cells, or neurons, with branches that connect at more than 100 trillion points. They are constantly sending signals through a vast neuron forest that forms memories, thoughts and feelings; these patterns of activity form the essence of each person.

Researchers develop effective technique for studying high-arched palate using mouse model

Researchers from the laboratory of Paul Trainor, Ph.D., at the Stowers Institute of Medical Research have developed an effective and reliable technique for studying high-arched palate using a mouse model. The methodology could expand research into the genetic aspects of this craniofacial abnormality.

Over-expression of heme oxygenase-1 enzyme protects the heart from doxorubicin damage

Life-threatening heart damage is an adverse side effect of the cancer drug doxorubicin, damage that also limits the use of newer chemotherapeutic agents such as trastuzumab and imatinib. The ability to protect the heart from these side effects would benefit patients, including cancer survivors who are at risk of developing heart damage years later, and it also could allow safer use of these drugs at higher doses.

Consuming dried plums can protect from radiation-induced bone loss

Dr. Nancy Turner, a Texas A&M AgriLife Research scientist in College Station, was one of a team of researchers who recently studied different interventions to protect from radiation-induced bone loss.

Determining Ectopeptidase Activity: An Interview with Professor Stephen Weber, University of Pittsburgh

The scope of the activity of neuropeptides is remarkably broad. For example, neuropeptides are involved in pain control, mood/depression/eating disorders, social and emotional behaviour, body weight, drug abuse, stress, reproduction, motor control, memory, and in maintaining neuronal health when they are stressed.
