Project Snapshot
In 2012, the AMDA awarded the Helen Walker Research Grant to Nuno Raimundo, PhD, at the University of Göttingen, Faculty of Medicine, in Germany, to investigate new therapeutic strategies aimed at improving muscle function in Pompe disease. While enzyme replacement therapy has significantly improved patient outcomes, it primarily addresses the underlying enzyme deficiency and may not fully correct the complex cellular dysfunction associated with the disease.
This project focused on understanding how mitochondrial dysfunction and impaired autophagyThe cell's internal cleanup system that removes damaged or unneeded material. More contribute to the muscle pathology observed in Pompe disease. The research aimed to determine whether improving mitochondrial performance and enhancing cellular recycling pathways could alleviate symptoms of acid maltase deficiency.
Using mouse models of Pompe disease, the research examined genetic and pharmacological approaches designed to increase mitochondrial function and promote the removal of damaged cellular components. These studies were intended to identify potential therapeutic strategies that could complement existing treatments and improve muscle health in individuals living with Pompe disease.
Research Objectives
The project aimed to address several key questions related to treatment outcomes in Pompe disease:
1. Increase mitochondrial performance to improve skeletal muscle function in Pompe disease
Researchers investigated whether enhancing mitochondrial biogenesis in skeletal muscle could alleviate the muscle pathology associated with Pompe disease. This approach involved crossing Pompe disease mouse models with transgenic mice engineered to increase mitochondrial content and activity.
2. Increase autophagy and lysosomal clearance in skeletal muscle
3. Evaluate pharmacologic activation of mitochondrial and autophagy pathways
Why This Matters
Pompe disease results from the buildup of glycogen within lysosomes due to a deficiency of the enzyme acid alpha-glucosidase. While enzyme replacement therapy addresses the underlying enzyme deficiency, research increasingly suggests that secondary cellular effects — such as mitochondrial dysfunction and impaired autophagyThe cell's internal cleanup system that removes damaged or unneeded material. More — also contribute to muscle pathology.
By exploring therapeutic strategies that target these additional cellular pathways, this research aimed to identify new approaches that could complement existing treatment and improve long-term outcomes for people living with Pompe disease.
