Technique for analyzing the function of microRNAs wins Barenholz Prize for Hebrew University student

A unique technique for analyzing the function of microRNAs developed by a Hebrew University of Jerusalem doctoral student has led to the discovery of a new mechanism by which viruses evade the human immune system. This discovery has important implications for human intervention in the battle between viruses and humans.

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.

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.

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.
