Overexpression of SMN2 Gene in Motoneuron-Like Cells Differentiated from Adipose-Derived Mesenchymal Stem Cells by Ponasterone A.

J Mol Neurosci 2018 Dec 7. Epub 2018 Dec 7.

Applied Cell Sciences and Tissue Engineering Department, School of Advanced Technologies in Medicine, Tehran University of Medical Sciences, Tehran, Iran.

Cell therapy and stem cell transplantation strategies have provided potential therapeutic approaches for the treatment of neurological disorders. Adipose-derived mesenchymal stem cells (ADMSCs) are abundant adult stem cells with low immunogenicity, which can be used for allogeneic cell replacement therapies. Differentiation of ADMSCs into acetylcholine-secreting motoneurons (MNs) is a promising treatment for MN diseases, such as spinal muscular atrophy (SMA), which is associated with the level of SMN1 gene expression.

O'Sullivan-McLeod syndrome: Unmasking a rare atypical motor neuron disease.

Rev Neurol (Paris) 2018 Nov 5. Epub 2018 Nov 5.

Division of Neuromuscular Diseases, Department of Neurology and Neurosurgery, Federal University of São Paulo (UNIFESP), São Paulo, SP, Brazil.

Atypical motor neuron disease represents a rare heterogeneous group of neurodegenerative disorders with clinical, genetic and neuroimaging features distinct from those of the classic spinal or bulbar-onset amyotrophic lateral sclerosis (ALS). O'Sullivan-McLeod syndrome represents an extremely rare lower motor neuronopathy with early adult-onset distal amyotrophy and weakness in the upper limbs with asymmetrical involvement. To add to the few case series and epidemiological and genetic studies describing this variant syndrome, our team here presents a series of seven unrelated Brazilian patients with O'Sullivan-McLeod syndrome in a detailed review of their clinical, neuroimaging, laboratory and neurophysiological findings.

The neurodegenerative diseases ALS and SMA are linked at the molecular level via the ASC-1 complex.

Nucleic Acids Res 2018 Dec;46(22):11939-11951

Department of Cell Biology, Harvard Medical School, 240 Longwood Ave. Boston MA 02115, USA.

Understanding the molecular pathways disrupted in motor neuron diseases is urgently needed. Here, we employed CRISPR knockout (KO) to investigate the functions of four ALS-causative RNA/DNA binding proteins (FUS, EWSR1, TAF15 and MATR3) within the RNAP II/U1 snRNP machinery. We found that each of these structurally related proteins has distinct roles with FUS KO resulting in loss of U1 snRNP and the SMN complex, EWSR1 KO causing dissociation of the tRNA ligase complex, and TAF15 KO resulting in loss of transcription factors P-TEFb and TFIIF.

Department of Respiratory Medicine, The Children's Hospital at Westmead, Sydney, NSW, Australia; Discipline of Child and Adolescent Health, Sydney Medical School, University of Sydney, Sydney, NSW, Australia.

Spinal muscular atrophy (SMA) is a degenerative motor neurone disorder causing progressive muscular weakness. Without assisted ventilation or novel therapies, most children with SMA type 1 die before the second year of life due to respiratory failure as the respiratory muscles and bulbar function are severely affected. Active respiratory treatment (mechanically assisted cough, invasive or non-invasive ventilation) has improved survival significantly in recent decades, but often at the cost of becoming ventilator dependent.

IGHMBP2 mutation associated with organ-specific autonomic dysfunction.

Neuromuscul Disord 2018 Dec 29;28(12):1012-1015. Epub 2018 Aug 29.

MRC Centre for Neuromuscular Diseases, National Hospital for Neurology and Neurosurgery and UCL Institute of Neurology, Queen Square, London WC1N 3AR, UK. Electronic address:

Biallelic mutations in the IGHMBP2 have been associated with two distinct phenotypes: spinal muscular atrophy with respiratory distress type 1 (SMARD1) and CMT2S. We describe a patient who developed progressive muscle weakness and wasting in her upper and lower limbs from infancy. She developed respiratory involvement at age 9, eventually requiring 24-h non-invasive ventilation, and severe autonomic dysfunction restricted to the gastrointestinal tract. Read More

Cell cycle inhibitors protect motor neurons in an organoid model of Spinal Muscular Atrophy.

Cell Death Dis 2018 Oct 27;9(11):1100. Epub 2018 Oct 27.

Institute of Molecular and Cell Biology, 61 Biopolis Drive, Singapore, 138673, Singapore.

Spinal Muscular Atrophy (SMA) is caused by genetic mutations in the SMN1 gene, resulting in drastically reduced levels of Survival of Motor Neuron (SMN) protein. Although SMN is ubiquitously expressed, spinal motor neurons are one of the most affected cell types. Previous studies have identified pathways uniquely activated in SMA motor neurons, including a hyperactivated ER stress pathway, neuronal hyperexcitability, and defective spliceosomes. Read More

Biomarkers of Spinal and Bulbar Muscle Atrophy (SBMA): A Comprehensive Review.

Front Neurol 2018 10;9:844. Epub 2018 Oct 10.

Laboratoire d'Imagerie Biomédicale, CNRS, INSERM, Sorbonne Université, Paris, France.

Spinal and bulbar muscular atrophy (SBMA), also known as Kennedy's disease, is a rare, X-linked, late onset neuromuscular disorder. The disease is caused by a CAG trinucleotide repeat expansion in the first exon of the androgen receptor gene. It is characterized by slowly progressive lower motor neurons degeneration, primary myopathy and widespread multisystem involvement. Read More

Human Cardiac Gene Therapy.

Circ Res 2018 Aug;123(5):601-613

From the Cardiovascular Research Center, Icahn School of Medicine at Mount Sinai, New York, NY.

In the past 10 years, there has been tremendous progress made in the field of gene therapy. Effective treatments of Leber congenital amaurosis, hemophilia, and spinal muscular atrophy have been largely based on the efficiency and safety of adeno-associated vectors. Myocardial gene therapy has been tested in patients with heart failure using adeno-associated vectors with no safety concerns but lacking clinical improvements. Read More

Multiplex Droplet Digital PCR Method Applicable to Newborn Screening, Carrier Status, and Assessment of Spinal Muscular Atrophy.

Clin Chem 2018 Dec 23;64(12):1753-1761. Epub 2018 Oct 23.

Departments of Laboratory Medicine and Pathology.

Background: Spinal muscular atrophy (SMA) is a progressive neuromuscular disorder with neuronal degeneration leading to muscular atrophy and respiratory failure. SMA is frequently caused by homozygous deletions that include exon 7 of the survival motor neuron gene , and its clinical course is influenced by the copy number of a nearby 5q paralog, . Multiple ligation probe amplification (MLPA) and real-time quantitative PCR (qPCR) can detect deletions. Read More

Stasimon/Tmem41b localizes to mitochondria-associated ER membranes and is essential for mouse embryonic development.

Biochem Biophys Res Commun 2018 Nov 22;506(3):463-470. Epub 2018 Oct 22.

Center for Motor Neuron Biology and Disease, Columbia University, New York, NY, 10032, USA; Department of Pathology and Cell Biology, Columbia University, New York, NY, 10032, USA. Electronic address:

Stasimon (also known as Tmem41b) is an evolutionarily conserved transmembrane protein first identified for its contribution to motor system dysfunction in animal models of the childhood neurodegenerative disease spinal muscular atrophy (SMA). Stasimon was shown to be required for normal neurotransmission in the motor circuit of Drosophila larvae and proper development of motor axons in zebrafish embryos as well as to suppress analogous neuronal phenotypes in SMA models of these organisms. However, the subcellular localization and molecular functions of Stasimon are poorly understood. Read More

Lumbosacral ventral spinal nerve root atrophy identified on MRI in a case of spinal muscular atrophy type II.

Clin Imaging 2019 Jan - Feb;53:134-137. Epub 2018 Oct 5.

Department of Radiology, University of Florida College of Medicine, 1600 SW Archer Road, Gainesville, FL 32610, USA. Electronic address:

Spinal muscular atrophies are rare genetic disorders most often caused by homozygous deletion mutations in SMN1 that lead to progressive neurodegeneration of anterior horn cells. Ventral spinal root atrophy is a consistent pathological finding in post-mortem examinations of patients who suffered from various subtypes of spinal muscular atrophy; however, corresponding radiographic findings have not been previously reported. We present a patient with hypotonia and weakness who was found to have ventral spinal root atrophy in the lumbosacral region on MRI and was subsequently diagnosed with spinal muscular atrophy.

Safety, tolerability, and preliminary efficacy of an IGF-1 mimetic in patients with spinal and bulbar muscular atrophy: a randomised, placebo-controlled trial.

Lancet Neurol 2018 Dec 15;17(12):1043-1052. Epub 2018 Oct 15.

Neurogenetics Branch, National Institute of Neurological Disorders and Stroke, National Institutes of Health, Bethesda, MD, USA.

Background: Spinal and bulbar muscular atrophy is an X-linked neuromuscular disease caused by CAG repeat expansion in the androgen receptor gene. Patients with this disease have low concentrations of insulin-like growth factor-1 (IGF-1), and studies of overexpression and administration of IGF-1 showed benefit in a transgenic model; thus the IGF-1 pathway presents as a potential treatment target. We assessed safety, tolerability, and preliminary efficacy of BVS857, an IGF-1 mimetic, in patients with spinal and bulbar muscular atrophy. Read More

Trehalose induces autophagy via lysosomal-mediated TFEB activation in models of motoneuron degeneration.

Autophagy 2018 Oct 18:1-21. Epub 2018 Oct 18.

a Dipartimento di Scienze Farmacologiche e Biomolecolari (DiSFeB), Centro di Eccellenza sulle Malattie Neurodegenerative , Università degli Studi di Milano , Milano , Italy.

Macroautophagy/autophagy, a defense mechanism against aberrant stresses, in neurons counteracts aggregate-prone misfolded protein toxicity. Autophagy induction might be beneficial in neurodegenerative diseases (NDs). The natural compound trehalose promotes autophagy via TFEB (transcription factor EB), ameliorating disease phenotype in multiple ND models, but its mechanism is still obscure. Read More
