Defective RNA Processing Linked to Cardiac Problems Seen in Myotonic Dystrophy Patients

Researchers have discovered the molecular mechanisms responsible for the heart dysfunctions that mark myotonic dystrophy, and reported they appear to be linked to a defective processing of the cardiac sodium channel (SCN5A) RNA. Their study, published in Nature Communications, is titled “Splicing misregulation of SCN5A contributes to cardiac-conduction delay and…

Molecular Signatures of Key Protein Deficiencies in Muscular Dystrophy Identified in Study

University of Iowa researchers, working in a mouse model of muscular dystrophy (MD), have established new molecular signatures associated with membrane protein complexes that typify the disease, possibly opening the way to new and suitable therapies, according to the study, “Molecular signatures of membrane protein complexes underlying muscular dystrophy,” published in …
