AMP-activated protein kinase essential contributor to brain growth

An enzyme researchers have studied for years because of its potential connections to cancer, diabetes, heart disease, hypertension and stroke, appears to have yet another major role to play: helping create and maintain the brain.

Small molecules block cancer gene

Finding molecules that block the activity of the oncogene Stat 3 (signal transducer and activator of transcription) required screening literally millions of compounds, using computers that compared the structure of the cancer-causing gene to those of the small molecules, said a Baylor College of Medicine researcher in a report that appears in the current online issue of the journal PLoS One (Public Library of Science ONE).

New procedure for eliminating reblockage of arteries

An easily implementable technique to avoid reblockage of arteries that have been cleared through angioplasty and stent insertion has been developed by researchers led by Prof. Boris Rubinsky of the Hebrew University of Jerusalem.

Genetic link between cats and humans for retinitis pigmentosa

About one in 3,500 people are affected with retinitis pigmentosa (RP), a disease of the retina's visual cells that eventually leads to blindness.

Molecule provides clues about how HPV may lead to cancer

New research shows for the first time that certain types of human papillomavirus (HPV), which cause cervical and some other types of cancer, can inhibit the production of a tiny single-stranded RNA called microRNA 34a, or miR-34a.

New protein identified in bacterial arsenal

Nearly a billion years ago, bacteria evolved an insidious means of infecting their hosts - a syringe-like mechanism able to inject cells with stealthy hijacker molecules. These molecules, called virulence factors, play a sophisticated game of mimicry, imitating many of the cells' normal activities but ultimately co-opting them to serve the bacteria's needs.

Protein found linking stress and depression

Stress, the ever-present threat to health and happy living, is tough on the brain. If the strain goes on too long, it can lead to debilitating psychological problems.

Take 2: What protein and where it is located are important for drug design

Drugs that target a single signaling pathway that drives tumor development and/or progression have been developed successfully to treat a few forms of cancer.

Nanoparticles detect dying cancer cells

Two years ago, researchers at the University of South Australia discovered a new molecular marker specific for chemotherapy-induced cancer cell death. Now, those same investigators have used this marker to develop an imaging agent that can pinpoint tumor cell death using magnetic resonance imaging.

Forgotten and lost -- when proteins 'shut down' our brain

Which modules of the tau protein, in neurons of Alzheimer disease patients, may act in a destructive manner were investigated by researchers from the Max Planck Institute for Biophysical Chemistry (Göttingen) and the Max Planck Unit for Structural Molecular Biology (Hamburg) with the help of Nuclear Magnetic Resonance Spectroscopy ( PLoS Biology , February 17, 2009).

Researchers identify mutation that causes inflammatory bowel disease

A team of scientists at The Scripps Research Institute has linked a mouse mutation to an increased susceptibility for developing inflammatory bowel disease -- represented in humans as Crohn's disease and ulcerative colitis, which together are estimated to affect more than a million people in the United States.
