Epigenetic changes occur over a person's lifetime

Researchers at Johns Hopkins have found that epigenetic marks on DNA-chemical marks other than the DNA sequence-do indeed change over a person's lifetime, and that the degree of change is similar among family members.

Quantum dots stop RNA interference in living cells

More than 15 years ago scientists discovered a way to stop a particular gene in its tracks. The Nobel Prize-winning finding holds tantalizing promise for medical science, but so far it has been difficult to apply the technique, known as RNA interference, in living cells.

Genetic mutation and cat exposure at birth may increase a child's risk of developing eczema

A gene mutation and cat exposure at birth may increase a child's risk of developing eczema during their first year according to a study published in PLoS Medicine. Researchers led by Professor Hans Bisgaard (University Hospital Gentofte, Copenhagen, Denmark) studied the association between mutations in the filaggrin gene (FLG) and exposure to environmental factors with the development of eczema.

Viruses hitch a ride in the cell

Viruses can travel around cells they infect by hitching a ride on a microscopic transport system, according to new research. Cells are exposed to foreign DNA and RNA and it is understood that some of this genetic material can be integrated into the host genome. Using modern microscopic techniques, scientists have been able to see how virus DNA is transported in the cell.

Drug rapamycin reverses mental retardation caused by tuberous sclerosis complex

UCLA researchers discovered that an FDA-approved drug reverses the brain dysfunction inflicted by a genetic disease called tuberous sclerosis complex (TSC). Because half of TSC patients also suffer from autism, the findings offer new hope for addressing learning disorders due to autism. Nature Medicine publishes the findings in its online June 22 edition.

New, previously unrecognized source of heart stem cells discovered

Researchers at Children's Hospital Boston are continuing to document the heart's earliest origins. Now, they have pinpointed a new, previously unrecognized group of stem cells that give rise to cardiomyocytes, or heart muscle cells. These stem cells, located in the surface of the heart, or epicardium, advance the hope of being able to regenerate injured heart tissue.

Hormone could hold the key to staying slim

Researchers in the United states are suggesting that the key to maintaining a healthy weight may be related to a hormone produced by the body.

Risk factors for sudden death for adult muscular dystrophy identified

The largest assessment of people with adult muscular dystrophy has identified risk factors that can lead to sudden death for individuals with the most common form of this disease.

Discovery of new biomarkers for growth hormone - potential for detecting growth hormone abuse

Researchers have found potential new biomarkers for growth hormone, which they say could help the sports community in detecting growth hormone abuse. The results of the animal study will be presented at The Endocrine Society's 90th Annual Meeting in San Francisco.

Melanomas "run" in families - CDKN2A gene reveals why

When people know the results of genetic tests confirming they have inherited an increased risk of developing melanoma, they follow skin cancer screening recommendations more proactively-much like those who have already been diagnosed with the potentially deadly disease, according to results of a study completed at the University of Utah's Huntsman Cancer Institute. and published in the June issue of Cancer Epidemiology, Biomarkers & Prevention.

Five common genetic variations linked to metabolic syndrome and HDL cholesterol levels

Nutrition researchers at Washington University School of Medicine in St. Louis have identified five common genetic variations that increase the risk of metabolic syndrome, a group of factors linked to heart disease and diabetes. Another variant they found appeared to protect against the condition.

Like father like son - history of heart attacks in the family

Scientists know that heredity plays an important role in causing heart attacks. However the exact genetic mechanisms that transmit the risk of heart attacks from generation to generation still elude them.

Australian scientists discover digestive super bugs with potential to improve human health

Scientists in Victoria, Australia have made a world-first discovery of thousands of never-before-identified digestive super bugs living inside cows' stomachs, which may lead to environmental, agricultural and human health benefits.

Salmonella tomato outbreak spreads in the U.S.

According to officials in the U.S. a salmonella outbreak linked to tainted tomatoes has expanded to five more states and the district of Columbia.

Gene radiotherapy system shows promise for fighting treatment-resistant cancer cells

A gene radiotherapy system that detects and treats cancer cells that are resistant to traditional forms of chemotherapy and radiation showed success in the laboratory and could eventually prove beneficial for cancer patients, according to researchers at the Society of Nuclear Medicine's 55th Annual Meeting.

HIPAA Privacy Rule is having a negative impact on the advance of biomedical research

The privacy rule of the Health Insurance Portability and Accountability Act (HIPAA) is having a negative impact on the advance of biomedical research and the search for treatments that benefit society, says a newly-released report by the Association of Academic Health Centers (AAHC).

Society's attitudes have little impact on choice of sexual partner

A unique new study from the Swedish medical university Karolinska Institute (KI) suggests that the attitude of families and the public have little impact on if adults decide to have sex with persons of the same or the opposite sex. Instead, hereditary factors and the individual's unique experiences have the strongest influence on our choice of sexual partners.

European researchers take lid off the genome

European researchers have made significant progress unravelling how genes are governed and why this sometimes goes wrong in disease.

Integrated control of malaria and other vector diseases is crucial

Combating malaria and other so-called vector diseases with chemical controls is increasingly ineffective, besides being hazardous for humans and the environment. These chemical controls must therefore be eliminated. In order to combat the diseases that insects and ticks transmit, all possible strategies must be united.
