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 diseaseA rare genetic disease in which the body cannot properly break down glycogen, leading to buildup tha...

Research Objectives
The project aimed to address several key questions related to treatment outcomes in Pompe diseaseA rare genetic disease in which the body cannot properly break down glycogen, leading to buildup tha... More:
1. Increase mitochondrial performance to improve skeletal muscle function in Pompe disease
Researchers investigated whether enhancing mitochondrialParts of the cell that produce energy. More biogenesis in skeletal muscleMuscles that control movement and are commonly affected in Pompe disease. More could alleviate the muscle pathology associated with Pompe diseaseA rare genetic disease in which the body cannot properly break down glycogen, leading to buildup tha... More. This approach involved crossing Pompe diseaseA rare genetic disease in which the body cannot properly break down glycogen, leading to buildup tha...

More content and activity.
2. Increase autophagy and lysosomal clearance in skeletal muscle
The study examined whether boosting autophagyThe cell's internal cleanup system that removes damaged or unneeded material. More and lysosomal biogenesis through TFEB overexpression could reduce lysosomal glycogen accumulationThe buildup of glycogen inside cells and tissues when it is not broken down properly. More and improve muscle function in a Pompe diseaseA rare genetic disease in which the body cannot properly break down glycogen, leading to buildup tha...

3. Evaluate pharmacologic activation of mitochondrial and autophagy pathways
Researchers tested whether drugs known to stimulate mitochondrialParts of the cell that produce energy. More biogenesis and autophagyThe cell's internal cleanup system that removes damaged or unneeded material. More — such as bezafibrate and metformin — could improve muscle performance and cellular function in Pompe diseaseA rare genetic disease in which the body cannot properly break down glycogen, leading to buildup tha...

Why This Matters

More within lysosomesA small part of the cell that acts like a recycling center, helping break down waste materials. More due to a deficiency of the enzymeA protein that helps the body carry out chemical reactions. More acid alpha-glucosidase. While enzymeA protein that helps the body carry out chemical reactions. More replacement therapy addresses the underlying enzymeA protein that helps the body carry out chemical reactions. More deficiency, research increasingly suggests that secondary cellular effects — such as mitochondrialParts of the cell that produce energy. More 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 diseaseA rare genetic disease in which the body cannot properly break down glycogen, leading to buildup tha...
