Gladstone scientists identify genetic factors that hold promise for treatment of vascular diseases
Researchers at the Gladstone Institute of Cardiovascular Disease have discovered a key switch that makes stem cells turn into the type of muscle cells that reside in the wall of blood vessels.

Study in Nature: MicroRNAs hold promise for treating diseases in blood vessels
A newly discovered mechanism controls whether muscle cells in blood vessels hasten the development of both atherosclerosis and Alzheimer's disease, according to an article published online today in the journal Nature.

Pitt team finds molecule that regulates heart size by using zebrafish screening model
Using zebrafish, researchers at the University of Pittsburgh have identified and described in Nature Chemical Biology an enzyme inhibitor that increases the number of cardiac progenitor cells and influences the size of the developing heart.

GUMC discovery highlights new direction for drug discovery
In a discovery that rebuffs conventional scientific thinking, researchers at Georgetown University Medical Center have discovered a novel way to block the activity of the fusion protein responsible for Ewing's sarcoma, a rare cancer found in children and young adults.

DNA variations linked to brain tumors
Mayo Clinic researchers and colleagues at the University of California San Francisco have found a connection between DNA alterations on human chromosome 9 and aggressive brain cancer known as glioblastoma.

Researchers find possible environmental causes for Alzheimer's, diabetes
A new study by researchers at Rhode Island Hospital has found a substantial link between increased levels of nitrates in our environment and food with increased deaths from diseases, including Alzheimer's, diabetes mellitus and Parkinson's.

Famotidine prevents stomach and upper-intestinal ulcers in patients taking low-dose aspirin (FAMOUS trial)
There are many patients worldwide on low-dose aspirin for a variety of conditions, yet few treatments available to treat the damage that can be caused to the lining of the stomach and upper intestine that can be caused by this damage.

Caffeine reverses memory impairment in Alzheimer's mice
Coffee drinkers may have another reason to pour that extra cup.

Moles and melanoma -- researchers find genetic links to skin cancer
Research shows the genetic connection between moles and melanoma -- and why the more moles a person has, the more susceptible they are to the disease

Variations in 5 genes raise risk for most common brain tumors
Common genetic variations spread across five genes raise a person's risk of developing the most frequent type of brain tumor, an international research team reports online in Nature Genetics.
