Researchers discover target that could ease spinal muscular atrophy symptoms

...esearchers inhibited myostatin, a protein that limits muscle tissue growth. myostatin activity can be reduced significantly by enabling several proteins that bind to myostatin, including follistatin. When myostatin is inhibited, muscle mass and strength increase. SMA is caused by the ...

Scientists show drug can counteract muscular dystrophy in mice

... "If you block myostatin, you get big muscles." One way of inactivating myostatin is to upregulate follistatin. Basically, what follistatin does is to prevent myostatin from working, says Dr. Sartorelli. When his group treated the cells with de...
