Abstract:
There is still no curative treatment for Duchenne muscular dystrophy (DMD). In this issue of Cell Stem Cell, Young et al. (2016) demonstrate a genome editing approach applicable to 60% of DMD patients with CRISPR/Cas9 using one pair of guide RNAs.

Satellite Stem Cells and Muscular Dystrophy
2.5K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin
1.4K
Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.
