A clinical trial designed to replace the genetic defect causing the most common form of muscular dystrophy has uncovered an unexpected aspect of the disease. The trial, based on therapy designed by scientists at the University of North Carolina at Chapel Hill School of Medicine, showed that some patients mount an immune response to the dystrophin protein even before they have received the gene therapy.
An immune reaction to dystrophin, the muscle protein that is defective in patients with Duchenne muscular dystrophy, may pose a new challenge to strengthening muscles of patients with this disease, suggests a new study appearing in the October 7, 2010, issue of The New England Journal of Medicine.
In the October 1 issue of the journal Cell researchers at The Wistar Institute shed new light on the genetic unknown with the discovery of the ability of long non-coding RNA (ncRNA) to promote gene expression. The researchers believe these long ncRNA molecules may represent so-called gene enhancer elements—short regions of DNA that can increase gene transcription. While scientists have known about gene enhancers for decades, there has been no consensus about how these enhancers work.
