Possible susceptibility genes found in neurodegenerative disorder Posted: 19 Jun 2011 10:35 AM PDT Scientists have discovered three potential susceptibility genes for development of progressive supranuclear palsy (PSP), a rare neurodegenerative disease that causes symptoms similar to those of Parkinson's disease but is resistant to Parkinson's medications.

Fifty-year search for calcium channel ends: Cell's power generator depends on long-sought protein Posted: 19 Jun 2011 10:35 AM PDT After decades of failed efforts, researchers have discovered, through a combination of digital database mining and laboratory assays, the linchpin protein that drives mitochondria's calcium machinery.

Human vaccine used to cure prostate cancer in mice Posted: 19 Jun 2011 10:34 AM PDT Scientists cured well-established prostate tumors in mice using a human vaccine with no apparent side effects. This novel cancer treatment approach encourages the immune system to rid itself of prostate tumors without assistance from toxic chemotherapies and radiation treatments. Such a treatment model could some day help people to live tumor free with fewer side effects than those experienced from current therapies.

Cholesterol boosts antibiotic resistance in H. pylori Posted: 17 Jun 2011 03:49 PM PDT New research suggests that cholesterol boosts resistance in Helicobacter pylori both to many antibiotics and to the endogenous antimicrobial peptide, LL-37. A complete understanding of the pathway of cholesterol uptake might lead to novel strategies thwarting H. pylori by blocking that pathway.

Genetic mutation linked to asbestos exposure, mouse study suggests Posted: 15 Jun 2011 06:45 AM PDT Mice inhabiting an area known for its high concentration of asbestos-contaminated dust, have a higher level of genetic somatic mutations, compared with other regions where asbestos pollution levels are lower.
