Inverted DNA turns quiet developmental gene into a potent driver of t-cell lymphoma

A gene crucial for embryonic development can quickly become a potent cancer promoter in adult mice after a genetic misalignment, according to researchers from Fox Chase Cancer Center, causing white blood cells to become cancerous spontaneously.

Decline in cystic fibrosis since introduction of prenatal carrier screening

A brief report in the February 28, 2008, New England Journal of Medicine, led by researchers at the New England Newborn Screening Program (NENSP) of the University of Massachusetts Medical School (UMMS), indicates a declining incidence of a genetic disease, providing what may be the first demonstration of a link between two independent population-based screening programs.

Cause of effectiveness discovered for a cirrhosis treatment useful in 40 percent of patients

Scientists of the Center for Applied Medical Research (CIMA) of the University of Navarra have discovered the molecular mechanism responsible for the effectiveness of an existing treatment for primary biliary cirrhosis, which combines two substances in order to produce an effect that does not result from either substance separately.

Genetic mutation linked to peripheral artery disease

The finding, appearing online in the journal Circulation, is the first to document a genetic mutation linked to PAD. Although the work was done in mice, researchers say it is likely to give them new insight into how PAD develops and progresses in humans.
