New understanding of how the alpha-dystroglycan protein is glycosylated (sugar-coated) may have relevance for treating some forms of congenital and limb-girdle muscular dystrophy
Glycosylation — "sugar-coating" — of the muscle protein alpha-dystroglycan is known to be a crucial part of muscle function.
Without sufficient glycosylation, alpha-dystroglycan doesn't stick well to other proteins, and an important linkage between muscle fibers and their surroundings is disrupted.
Investigators have developed lab mice likely to advance understanding of the fukutin-deficient disorders Fukuyama congenital muscular dystrophy and type 2M limb-girdle muscular dystrophy
By disrupting the fukutin gene at different time points in mice embryo, researchers have been able to develop research models of two types of human muscle disease: Fukuyama congenital muscular dystrophy (Fukuyama CMD) and type 2M limb-girdle muscular dystrophy (LGMD2M).
The pace of research can seem unreasonably slow; here are a few reasons why
John Porter from the National Institutes of Health likes to start talks by noting, “It’s a great time to be a mouse with a neuromuscular disease.” Exciting research results are regularly reported, where a treatment appears to cure one neuromuscular disease or another in a mouse — yet there are few treatments available today for people with any of these diseases, and only a few treatments in human...

The biggest problem at an ER may not be the one you go in with, but the one you encounter there
When a medical emergency strikes — and the patient is a person with a neuromuscular disease — it’s not just getting to the emergency room quickly that’s critical. It’s also critical to ensure the ER staff understands the patient’s special needs caused by muscle disease.
Scientists have identified a protein cluster that patches damaged muscle-fiber membranes in muscular dystrophy.
Scientists in the United States and Japan have identified a three-protein cluster that reseals damaged muscle-fiber membranes. The findings, published June 5, 2009, in the Journal of Biological Chemistry, could have implications for development of treatments for muscular dystrophies.
