Grant - Winter 2016 - SMA - Livio Pellizzoni, M.D.
Livio Pellizzoni, associate professor at Columbia University Medical Center in New York, was awarded an MDA research grant totaling $200,000 over two years to elucidate the underlying mechanisms of spinal muscular atrophy (SMA). Although several strategies to restore SMN levels have shown promising results in preclinical studies and are currently being tested in clinical trials, it remains essential to understand the still elusive mechanisms by which low SMN causes SMA and to define other therapeutic targets that can be pursued in parallel to SMN-enhancing approaches. To address these issues, Pellizzoni will determine whether disruption of a novel function of SMN in RNA regulation contributes to SMA pathology in a well-established mouse model that recapitulates many features of the human disorder. This work has the potential to identify new research avenues for the development of therapeutic approaches that could complement current strategies for upregulation of SMN.

Grant - Winter 2016 - SMA - Franco Pagani, M.D.
Franco Pagani, at the International Centre for Genetic Engineering and Biotechnology in Trieste, Italy, was awarded an MDA research grant totaling $224,950 over a period of three years to investigate a new therapeutic strategy for spinal muscular atrophy (SMA). Pagani will study a small RNA molecule called Exon Specific U1 (ExSpeU1), which may be able to correct the splicing defect in the SMN2 gene, resulting in restored SMN protein levels. His work could result in a therapy that will achieve higher SMN protein levels than drugs currently in clinical trials for SMA.

Grant - Winter 2016 - periodic paralysis - Steve Cannon, M.D., Ph.D.
Steve Cannon, professor of physiology at the David Geffen School of Medicine at the University of California, Los Angeles, was awarded an MDA research grant totaling $300,000 over three years to investigate a new hypothesis about the underlying mechanisms involved in periodic paralysis. New preliminary studies in research models have revealed a profound loss of muscle force within minutes of recovery from exposure to high carbon dioxide levels, which Cannon and colleagues suggest may be a surrogate for the exercise-induced attacks of weakness that occurs in patients. Cannon and his team will investigate the mechanistic basis for exercise-induced weakness in periodic paralysis, will strategically select drugs that may block this process, and will test the potential of these drugs to foreshorten or prevent attacks of periodic paralysis.

Matthew Disney, a professor at the Scripps Research Institute in Jupiter, Fla., was awarded an MDA research grant totaling $300,000 over a period of three years to optimize two novel, drug-like compounds — one that targets toxic RNA in myotonic muscular dystrophy and another that targets toxic RNA in amyotrophic lateral sclerosis (ALS). Using innovative methods they have developed, Disney and colleagues will study the compounds in patient-derived cells and mouse models to identify any off-target effects, which could cause side effects. This work could accelerate treatments for myotonic muscular dystrophy and ALS.

Pradeep Reddy Dubbaka Venu, a research associate at the Salk Institute for Biological Studies, La Jolla, Calif., was awarded an MDA development grant totaling $180,000 over a period of three years to test a potential method for preventing transmission of mitochondrial myopathies by selective elimination of defective mitochondrial DNA in oocytes (immature egg cells). The approach involves using enzymes called nucleases to act as “molecular scissors” that are able to precisely enter mitochondria and specifically identify and eliminate mutated mitochondrial DNA. The feasibility of the approach has been demonstrated in mouse embryos, where it successfully prevented the transmission of targeted mitochondrial DNA to the next generation. Dubbaka Venu and colleagues will test the safety and efficacy of the approach in human oocytes from mitochondrial disease patients. If successful, this work could lead to the first-in-history correction of genetic diseases at the oocyte level and the potential eradication of mitochondrial diseases.

Louis Kunkel, professor of genetics and pediatrics at Children’s Hospital in Boston, was awarded an MDA research grant totaling $300,000 over a period of three years to identify genetic modifiers in facioscapulohumeral muscular dystrophy (FSHD). Disease severity among patients with FSHD varies widely, and may reflect the various contributions of genetic modifiers — genes that minimize or exacerbate symptoms. To identify genetic modifiers, Kunkel will screen the human genome, then validate hits both by cross-referencing with patient data and by determining effects in a zebrafish research model.

Peter Jones, associate professor in cell and developmental biology and neurology at University of Massachusetts Medical School in Worcester, was awarded a research grant totaling $300,000 over a period of three years to develop a research mouse model for facioscapulohumeral muscular dystrophy (FSHD). A major obstacle to FSHD drug development has been the absence of a mouse model that effectively recapitulates the human disease symptoms. Jones and colleagues have engineered a mouse model that contains the human DUX4 gene, based on the widely accepted understanding that FSHD is caused by increased expression of the gene. Now the team will work to develop different versions of the mouse to represent various levels of human FSHD disease severity. Successful completion of the project will provide the FSHD field with valuable tools for understanding what happens in the disease and for preclinical screening of different classes of potential therapies aimed at DUX4 and downstream targets.

Melissa Spencer, professor of neurology at the Regents of the University of California, Los Angeles, was awarded an MDA research grant totaling $450,988 over a period of three years to work with PTC Therapeutics on the development of a treatment for Duchenne muscular dystrophy (DMD). Expression of serum protein osteopontin is abnormally high in DMD patients and has been implicated in driving functional decline and increased fibrosis. In collaboration with PTC Therapeutics, Spencer aims to develop and test osteopontin inhibitors to block fibrosis and slow disease progression. This work will identify the best drug candidate among PTC Therapeutics’ lead compounds and will optimize its dosing regimen.

Bradley Olwin, a professor at the University of Colorado, Boulder, was awarded an MDA research grant totaling $300,000 over a period of three years to investigate the role satellite cells play in muscle repair in Duchenne muscular dystrophy (DMD). Current dogma states that repair of dystrophic muscle eventually fails due to depletion of satellite cells. Olwin has reported evidence of another possiblity: impaired activation (not loss) of these satellite cells may slow repair. Olwin will investigate whether satellite cell activation can be stimulated by the deletion of syndecan-3, and whether such stimulation promotes muscle repair. Further, he will determine whether it will improve repair in mouse models of congenital muscular dystrophy (CMD) and limb-girdle muscular dystrophy (LGMD).

Susan Hamilton, L.F. McCollum Chair in Molecular Physiology at Baylor College of Medicine in Houston, was awarded an MDA research grant totaling $300,000 over three years to further define the molecular mechanisms underlying central core disease (CCD) and develop new treatments. Hamilton will test three different types of therapeutic interventions in two mouse models of CCD. Since the two mouse models demonstrate different ways that mutations in the ryanodine receptor (RyR1) can lead to dysfunction, and the three drugs are already approved for use or currently in clinical trials for other diseases, these studies could lay the ground work for rapid development of therapies in CCD.
