Researchers have developed and validated four new cell lines derived from four patients with spinal muscular atrophy (SMA) with lower extremity predominance (SMA-LED) that can be used as a tool in studies of this rare form of spinal muscular atrophy. With the characteristics of the patient it was…

A small RNA molecule called miR-23a can prevent neuron degeneration and muscle wasting by acting as a protective modifier in cellular and animal models of spinal muscular atrophy (SMA), a study says. The study, “AAV9-Mediated Delivery of miR-23a Reduces Disease Severity in Smn2B-/SMA Model Mice,” was published in…

A new gene of unknown function, called FAM135B, is expressed at lower levels in a cellular model of spinal and bulbar muscular atrophy (SBMA) and is thought to play a role in supporting spinal motor neurons’ growth and survival, a study found. The study, “Phenotypic and molecular features underlying neurodegeneration of…

A new genetic approach to restore the expression of the gene that causes spinal muscular atrophy (SMA) in patients’ cells holds promise to effectively and permanently treat the disease, researchers suggest. The study, “Seamless genetic conversion of SMN2 to SMN1 via CRISPR/Cpf1 and single-stranded oligodeoxynucleotides in…

Researchers have shown that the technology called antisense oligonucleotides, used in the only FDA-approved therapy for SMA, Spinraza (nusinersen), can be improved upon. They designed two new sequences that significantly increased SMN production in human cells and in a mouse model of SMA when administered alone or combined. The…

Researchers in the Division of Pharmacology, Department of Biochemistry and Molecular Biology at Kobe University Graduate School of Medicine in Japan are looking at ways of modeling spinal muscular atrophy (SMA) using cells derived from SMA patients. In a recent report published in Stem…

Spinal muscular atrophy (SMA) is among the many motor neuron diseases that have no cure. One reason for the lack of cures is the inexistence of reliable in vitro disease models to be used as platforms for research and development of new drugs. This is partially attributed  to the difficulty in…
