The Protein Srebp2 Drives Cholesterol Formation in Prion-Infected Neuronal Cells Which May Promote Prion-Dependent Diseases
The regulating protein Srebp2 drives cholesterol formation, which prions need for their propagation, in prion-infected neuronal cells. view more (2009-11-19)
Study reveals why certain drug combinations backfire
Combination drug therapy has become a staple for treating many infections. For instance, doctors treat extensively drug resistant forms of tuberculosis with one drug that breaks down the pathogen's protective barriers and opens the door for another to deliver the deathblow. view more (2009-11-16)
Energy-saving powder
It is currently estimated that natural gas resources will be exhausted in 130 years; however, those reserves where extraction is cost-effective will only flow for another 60 years or so. view more (2009-11-12)
Mouse gene suppresses Alzheimer's plaques and tangles
Investigators at Burnham Institute for Medical Research (Burnham) and colleagues have identified a novel mouse gene (Rps23r1) that reduces the accumulation of two toxic proteins that are major players in Alzheimer's disease: amyloid beta and tau. view more (2009-11-12)
Amyloid beta protein gets bum rap
While too much amyloid beta protein in the brain is linked to the development of Alzheimer's disease, not enough of the protein in healthy brains can cause learning problems and forgetfulness, Saint Louis University scientists have found. view more (2009-11-10)
Possible help in fight against muscle-wasting disease
A compound already used to treat pneumonia could become a new therapy for an inherited muscular wasting disease, according to researchers at the University of Oregon and the University of Rochester School of Medicine and Dentistry in New York. view more (2009-11-09)
Clinical tests begin on medication to correct Fragile X defect
NIH-supported scientists at Seaside Therapeutics in Cambridge, Mass., are beginning a clinical trial of a potential medication designed to correct a central neurochemical defect underlying Fragile X syndrome, the most common inherited cause of intellectual disability. view more (2009-11-03)
A Potential Anti-cancer Agent
Pateamine A (PatA), a natural product first isolated from marine sponges, has attracted considerable attention as a potential anti-cancer agent, and now a new activity has been found for it, which may reveal yet another anti-cancer mechanism. view more (2009-11-03)
Scientists discover influenza's Achilles heel: Antioxidants
As the nation copes with a shortage of vaccines for H1N1 influenza, a team of Alabama researchers have raised hopes that they have found an Achilles' heel for all strains of the flu-antioxidants. view more (2009-10-30)
2-pronged protein attack could be source of SARS virulence
Ever since the previously unknown SARS virus emerged from southern China in 2003, University of Texas Medical Branch at Galveston virologists have focused on finding the source of the pathogen's virulence - its ability to cause disease. view more (2009-10-30)
Pumpkin skin may scare away germs
The skin of that pumpkin you carve into a Jack-o'-Lantern to scare away ghosts and goblins on Halloween contains a substance that could put a scare into microbes that cause millions of cases of yeast infections in adults and infants each year. view more (2009-10-29)
Moderate amounts of protein per meal found best for building muscle
For thousands of years, people have believed that eating large amounts of protein made it easier to build bigger, stronger muscles. Take Milo of Croton, the winner of five consecutive Olympic wrestling championships in the sixth century BC: If ancient writers are to be believed, he built his crushing strength in part by consuming 20 pounds of meat... view more...

Chemosensitivity of cancer cells depends on their protein dependency
Two different anti-apoptotic proteins support cancer cell survival via an identical mechanism, yet differ in their sensitivity to chemotherapeutic drugs, report Brunelle et al. The study will be published online October 26, 2009 and in the November 2, 2009 print issue of the Journal of Cell Biology (JCB). view more (2009-10-26)
Boston University scientists first to see RNA network in live bacterial cells
Scientists who study RNA have faced a formidable roadblock: trying to examine RNA's movements in a living cell when they can't see the RNA. Now, a new technology has given scientists the first look ever at RNA in a live bacteria cell-a sight that could offer new information about how the molecule moves and works. view more (2009-10-23)
Biochemical 'on-switch' could solve protein purification challenge
Drugs based on engineered proteins represent a new frontier for pharmaceutical makers. Even after they discover a protein that may form the basis of the next wonder drug, however, they have to confront a long-standing problem: how to produce large quantities of the protein in a highly pure state. view more (2009-10-23)
Harvard scientists bend nanowires into 2-D and 3-D structures
Taking nanomaterials to a new level of structural complexity, scientists have determined how to introduce kinks into arrow-straight nanowires, transforming them into zigzagging two- and three-dimensional structures with correspondingly advanced functions. view more (2009-10-22)
Single-stranded DNA-binding protein is dynamic, critical to DNA repair
Researchers report that a single-stranded DNA-binding protein (SSB), once thought to be a static player among the many molecules that interact with DNA, actually moves back and forth along single-stranded DNA, gradually allowing other proteins to repair, recombine or replicate the strands. view more (2009-10-22)
