Study suggests cell communication leads to weak bones in SMA

Mutations that cause spinal muscular atrophy (SMA) may trigger problems with how bone cells communicate, leading to abnormally weakened bones, according to a study done in mice and cells. The findings suggest that treatments aiming to normalize bone cell communication could help improve bone health in SMA patients, researchers…

SMA-1 kids can survive lung crisis with standard protocols: Study

Children with spinal muscular atrophy (SMA) type 1 can survive an episode of pediatric acute respiratory distress syndrome (pARDS), a type of life-threatening respiratory failure, according to a 12-year case series. While “pARDS remains a clinical challenge for SMA-1 children,” the researchers wrote, “the present series suggests survival is achievable…

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…
