osteopontin

A variant in the gene for the osteopontin protein has the potential to help predict disease course in Duchenne MD

posted on January 11, 2011 - 2:58pm
A team of scientists working in the United States and Italy has uncovered a variant in the gene for a protein called osteopontin that appears to reliably indicate disease severity in most (but likely not all) cases of Duchenne muscular dystrophy (DMD). The variant is apparently a genetic modifier of DMD, a disease in which the underlying cause is a mutation in the gene for the dystrophin protein...

Blocking a protein associated with inflammation and scarring helped mice with a DMD-like disease

A protein called osteopontin has been implicated as a cause of some of the detrimental inflammation and scarring ("fibrosis") of muscle tissue that takes place in Duchenne muscular dystrophy (DMD). Eliminating osteopontin was beneficial to mice with a DMD-like disease, and the researchers concluded that reducing osteopontin should be investigated as a possible therapy for DMD.
