Blocking small molecule improves motor symptoms in SMA mice

Blocking a small RNA molecule called miR-140-3b can improve motor function in a mouse model of spinal muscular atrophy (SMA), a study suggested. Reducing miR-140-3b activity increased the levels of KIF5A, a protein involved in the transport of mitochondria (cellular powerhouses) inside nerve fibers. “We believe that KIF5A has…

Genetic engineering eases motor symptoms in SMA mice

Modifications that help certain genetic information travel to specific parts of nerve cells can ease motor symptoms and help normalize communication between nerves and muscles in a mouse model of spinal muscular atrophy (SMA), a study reported. SMA disrupts this nerve-muscle communication, which occurs at sites called neuromuscular junctions…

Coordination lacking in transition from SMA pediatric to adult care

In a new interview-based study, adults with spinal muscular atrophy (SMA) reported a lack of care coordination during their transition from pediatric to adult care settings — along with poor communication, no clear transition plans, and a need to self-advocate. Despite these challenges, nearly three-quarters of patients still reported…

Preclinical study finds antidepressant may boost SMN

A preclinical study found that blocking the SMPD1 enzyme with available drugs such as the antidepressant clomipramine increases the levels of SMN, the protein missing in spinal muscular atrophy (SMA), potentially offering a new treatment strategy. “The strategy presented here represents not only a new therapeutic approach for this…

Video game may boost physical activity in children with SMA

The “Tales from the Magic Keep” exergame — a video game that uses body movements to promote physical activity — proved to be a feasible and engaging home-based tool for children and adolescents with spinal muscular atrophy (SMA), according to a small Canadian study. However, improving “gesture recognition is imperative…
