Stbd1 is highly elevated in skeletal muscle of Pompe disease mice but suppression of its expression does not affect lysosomal glycogen accumulation.
Abstract
Previous studies strongly suggest that starch binding domain containing protein 1
(Stbd1) plays an important role in intracellular glycogen trafficking into lysosomes.
We report here that Stbd1 expression is markedly increased in skeletal muscles but
not in heart and liver of GAA-KO mice. An AAV2/9 vector expressing a Stbd1-specific
shRNA effectively suppressed Stbd1 expression but did not alter lysosomal glycogen
accumulation in the affected tissues of GAA-KO mice. Our results indicate that inhibition
of Stbd1 does not appear to be an effective therapeutic approach for Pompe disease.

My overall research interests are finding effective treatment for human glycogen storage
diseases (GSDs) and other inherited metabolic disorders. My current research focuses
on identification of novel therapeutic targets and development of effective therapies
for GSD II (Pompe disease), GSD III (Cori disease), and GSD IV (Andersen disease)
using cellular and animal disease models. The main therapeutic approaches we are using
in our pre-clinical studie
