Analysis

Cover story

Testing Parkinson's metal

Two multinational research teams have made a case for blocking iron accumulation in the brain to treat Parkinson's disease—a finding that could provide a path for creating disease-modifying PD drugs. The studies support the strategy taken by Prana Biotechnology, which is developing metal-binding compounds for PD.

Targets & Mechanisms

A structural fix for DMD

UCLA researchers have found that increasing expression of the structural protein sarcospan improves dystrophic pathology in mice with Duchenne muscular dystrophy. The question is whether increasing sarcospan will only slow muscle degeneration, and thus simply delay progression of the disease.

Tools

Micromanaging oncolytic viruses

Two research teams have applied a microRNA-based strategy for restricting the replication of oncolytic viruses to their target tumors. The approach seeks to avoid attenuation of the viral genome, a currently used technique that has so far avoided off-target effects but also limited the effectiveness of these agents as cancer therapies.

Fragment-based reality check

Burnham researchers have developed a fragment-based approach to lead discovery that identifies inhibitors of protein-protein interactions faster and more efficiently than computational or synthetic methods alone.
