Problems in IL-6 Pathway Linked to Severe Symptoms of Congenital Myotonic Dystrophy in Study

Aberrant signaling in the IL-6 pathway, which is involved in muscle cell maturation, contributes to the severe symptoms seen in congenital myotonic dystrophy (CDM) patients, researchers in Japan report. The study, “Aberrant Myokine Signaling in Congenital Myotonic Dystrophy” published in the journal Cell Reports, also suggests that treatments aimed at regulating…

High Levels of Sarcolipin Protein Underlie Muscle Wasting, Cardiac Disease in DMD

Researchers have found that lowering the the levels of a protein called sarcolipin lessens muscle weakness and improves skeletal and cardiac muscle function in a mouse model of Duchenne muscular dystrophy (DMD). These findings suggest that therapeutics targeting sarcolipin may have significant benefits to DMD patients. The study “Reducing sarcolipin expression…
