Thomas A. Cooper, M.D.



Dr. Cooper received the award for his work on the pathogenic mechanism of myotonic dystrophy, a microsatellite expansion disorder. His lab was instrumental in demonstrating that the RNA from the expanded repeat is pathogenic. The work highlighted by these publications from the past two years have identified a previously unknown role for metabolic changes in skeletal muscle wasting, a similarly unknown role for altered expression of both miRNAs and mRNAs due loss of MEF2 activity and demonstrate the efficacy of a novel therapeutic approach using antisense oligonucleotide (ASO)-directed RNase H degradation of the toxic RNA. This approach is expected to complete phase 1 and phase 2 trials this year.

Dr. Cooper’s nomination was based on the following publications:
