Abstract
Spinal muscular atrophy (SMA) is an inherited disease characterized by progressive motor neuron death and subsequent muscle weakness and is caused by deletion or mutation of survival motor neuron (SMN) 1 gene. Protecting spinal motor neuron is an effective clinical strategy for SMA. The purpose of this study was to investigate the potential effect of an anti-epileptic drug levetiracetam on SMA. In the present study, we used differentiated spinal motor neurons (MNs) from SMA patient-derived induced pluripotent stem cells (SMA-iPSCs) to investigate the effect of levetiracetam. Levetiracetam promoted neurite elongation in SMA-iPSCs-MNs. TUNEL-positive spinal motor neurons were significantly reduced by levetiracetam in SMA-iPSCs-MNs. In addition, the expression level of cleaved-caspase 3 was decreased by levetiracetam in SMA-iPSCs-MNs. Furthermore, levetiracetam improved impaired mitochondrial function in SMA-iPSCs-MNs. On the other hand, levetiracetam did not affect the expression level of SMN protein in SMA-iPSCs-MNs. These findings indicate that levetiracetam has a neuroprotective effect for SMA.

Ethics Statement
The procedures used in the experiments on human induced pluripotent stem cells (Control iPSCs; 201B7 line) adhered to the tenets of the Declaration of Helsinki. The 201B7 line was generated from adult human dermal fibroblasts which was purchased from Cell Applications, Inc (San Diego, CA, USA) [36]. The somatic cells collection from the patients, the establishment of patient-derived iPSCs, and pathological analysis of differentiated iPSCs including evaluation of the potential drug efficacy were planned in this study. These planed protocols were approved by the Ethics Review Committee of the National Hospital Organization, Nagara Medical Center (Approval Number: 26-15), and informed consents were obtained from the parents of our pediatric patients. Informed consents were obtained from the subjects after explanation of the nature and possible consequences of the study.
