Expansion of (GAA)n repeats in the first intron of the Frataxin gene is associated with reduced mRNA and protein levels and the development of Friedreich's ataxia. (GAA)n expansions form non-canonical structures, including intramolecular triplex (H-DNA), and R-loops and are associated with epigenetic modifications. With the aim of interfering with higher order H-DNA (like) DNA structures within...
Glycogen is present in all tissues, but it primarily stored the liver and muscle. As a branched chain carbohydrate, broken down by phosphorylase debrancher enzymes, which are cytoplasmic. It also degraded lysosomal α-glucosidase (GAA) known as acid α-glucosidase. The deficiency of GAA patients Pompe disease, phenotypes infantile, juvenile later onset forms. disease treated enzyme replacement th...

BACKGROUND Friedreich ataxia (FRDA) is an autosomal recessive neurodegenerative disorder, caused by a GAA repeat expansion mutation within intron 1 of the FXN gene. We have previously established and performed preliminary characterisation of several human FXN yeast artificial chromosome (YAC) transgenic FRDA mouse models containing GAA repeat expansions, Y47R (9 GAA repeats), YG8R (90 and 190 G...
Duvoglustat HCl (AT2220, 1-deoxynojirimycin) is an investigational pharmacological chaperone for the treatment of acid α-glucosidase (GAA) deficiency, which leads to the lysosomal storage disorder Pompe disease, which is characterized by progressive accumulation of lysosomal glycogen primarily in heart and skeletal muscles. The current standard of care is enzyme replacement therapy with recombi...
Recombinant human Acid Alpha Glucosidase (GAA) is the therapeutic enzyme used for the treatment of Pompe disease, a rare genetic disorder characterized by GAA deficiency in the cell lysosomes (Raben et al., Curr Mol Med. 2002; 2:145-166). The manufacturing process for GAA can be challenging, in part due to protease degradation. The overall goal of this study was to understand the effects of GAA...
Friedreich's ataxia (FRDA) is an autosomal recessive neurodegenerative disorder caused by a GAA repeat expansion mutation within intron 1 of the FXN gene, resulting in reduced levels of frataxin protein. We have previously reported the generation of human FXN yeast artificial chromosome (YAC) transgenic FRDA mouse models containing 90-190 GAA repeats, but the presence of multiple GAA repeats wi...
Background: In various cancers, Ganoderic Acid A (GAA), an active triterpenoid derived from Ganoderma lucidum, has been proved to show potent anti-tumor effects. However, the possible impacts of GAA on the human leukemia cell line (Nalm-6) are not fully elucidated. Therefore, this research aimed to study the antineoplastic effect of GAA on Nalm-6 cells. Materials and Methods: In this laborator...
Glycogen storage disease type II is a lysosomal storage disorder due to mutations of the GAA gene, which causes lysosomal alpha-glucosidase deficiency. Clinically, glycogen storage disease type II has been classified in infantile and late-onset forms. Most late-onset patients share the leaky splicing mutation c.-32-13T>G. To date, the mechanism by which the c.-32-13T>G mutation affects the GAA ...
Pompe disease is an inherited lysosomal storage disorder that results from a deficiency in acid α-glucosidase (GAA) activity due to mutations in the GAA gene. Pompe disease is characterized by accumulation of lysosomal glycogen primarily in heart and skeletal muscles, which leads to progressive muscle weakness. We have shown previously that the small molecule pharmacological chaperone AT2220 (1...
