MicroRNA undermines tumor suppression

Scientists at the Whitehead Institute for Biomedical Research and the National University of Singapore have discovered the first microRNA (miRNA) capable of directly tamping down the activity of the well known tumor-suppressor gene, p53, While p53 functions to prevent tumor formation, the p53 gene is thought to malfunction in more than 50% of cancerous tumors.

Drug pactimibe does not appear to reduce progression of atherosclerosis

Compared to placebo, the drug pactimibe did not effect certain measures of atherosclerosis for patients with familial hypercholesterolemia (high cholesterol levels), but these patients did have an increased incidence of cardiovascular events such as heart attack and stroke, according to a study in the March 18 issue of JAMA.

Alzheimer's mechanism suggests combination therapy needed

Researchers at the University of Illinois at Chicago College of Medicine have discovered a mode of action for mysterious but diagnostic protein snarls found in the brains of Alzheimer's patients that suggests a one-two punch of therapy may be needed to combat the neurodegenerative disease.

Scientists 'watch' as individual alpha-synuclein proteins change shape

In an Early Edition publication of The Proceedings of the National Academy of Sciences (PNAS) this week, the researchers demonstrate the "alpha-synuclein dance" - the switching back and forth of the protein between a bent helix and an extended helix as the surface that it is binding to changes.
