Dr. Jack Puymirat M.D., Ph.D., is a neurologist, clinician-scientist at the CHU Research Centre of Quebec, and professor in the Department of Medicine at Laval University. His work focuses on the study of neuromuscular diseases, headaches, as well as the development of a platform for the production of induced pluripotent human stem cells. Recently, his work on stem cell production was featured on Radio-Canada’s Découverte program. He has received several nominations, including the 2006 Researcher of the Year Award from Muscular Dystrophy Canada and the 2011 Hans Steinert Award from international myotonic dystrophy (Steinert’s disease) consortium.

Research on neuromuscular diseases

Steinert myotonic dystrophy is a muscular dystrophy that is 20 times more prevalent in the Saguenay-Lac-Saint-Jean region than anywhere else in the world. In 2000, it was established that the disease was due to the accumulation of mutated RNAs in the cell nucleus. Dr. Puymirat’s research has focused on the development of gene therapy, based on the destruction of toxic RNAs by antisense oligonucleotides. In 2016, his work led to the first Phase 1 clinical trial in the United States. In parallel with his research, Dr. Puymirat and his team have a clinical research program focusing on: 1) The establishment of a provincial registry for this disease to facilitate research and patient participation in clinical trials. 2) The development and validation of protocols for the quantification of muscle strength, the study of muscle imaging and the search for biomarkers of the disease for future clinical trials. 3) The development of genetic tests for various neuromuscular diseases, tests which are now used clinically and offered to the population of Quebec.

The induced pluripotent stem cells production platform (iPSC)

Thanks to the financial support of Brain Canada, Dr. Puymirat and his team have developed a platform for the production of induced pluripotent human stem cells. These cells can be derived from skin, blood, urine and immortalized lymphoblastic cell lines. These cells can differentiate into various cell types, particularly neurons, muscle cells and heart cells. They are used to model neurodegenerative, neuromuscular and psychiatric diseases, screen drugs, and develop cell therapies.

Pharmacogenomics in migraine

This research aims to identify blood molecular markers that are predictive of the response to different drugs used in the treatment of migraine. As a first step, Dr. Puymirat and his team are developing a migraine patient registry, which is essential for genomics studies. This registry contains information on the response to different drugs and will be extended to the CHUM as well as the Montreal Neurological Institute.
