First Look: How a hitch in RNA splicing could lead to muscle disorders

Researchers studying muscle function in mice may have hit upon a key to conditions like muscular dystrophy.


ur limbs wouldn’t move properly if our cells didn’t start pumping out an adult form of certain proteins, rather than the fetal form, at a key moment in their development.

Now, researchers have begun playing with that process — and their discoveries shed new light on a number of muscular disorders. The findings could also suggest new avenues for treatment.
