Gene therapy for glycogen storage diseases.

Journal Article J Inherit Metab Dis · January 2024 Glycogen storage disorders (GSDs) are inherited disorders of metabolism resulting from the deficiency of individual enzymes involved in the synthesis, transport, and degradation of glycogen. This literature review summarizes the development of gene therapy ... Full text Link to item Cite

Development of hepatocellular adenomas in a patient with glycogen storage disease Ia treated with growth hormone therapy.

Journal Article JIMD Rep · September 2023 Glycogen storage disease Ia (GSD Ia), also known as von Gierke disease, is caused by pathogenic variants in the G6PC1 gene (OMIM 232200) which encodes glucose-6-phosphatase. Deficiency of glucose-6-phosphatase impairs the processes of gluconeogenesis and g ... Full text Link to item Cite

Diagnosis and management of glycogen storage disease type IV, including adult polyglucosan body disease: A clinical practice resource.

Journal Article Mol Genet Metab · March 2023 Glycogen storage disease type IV (GSD IV) is an ultra-rare autosomal recessive disorder caused by pathogenic variants in GBE1 which results in reduced or deficient glycogen branching enzyme activity. Consequently, glycogen synthesis is impaired and leads t ... Full text Link to item Cite

Case report: Expanding the understanding of the adult polyglucosan body disease continuum: novel presentations, diagnostic pitfalls, and clinical pearls

Journal Article Frontiers in Genetics · January 1, 2023 Introduction: Adult polyglucosan body disease (APBD) has long been regarded as the adult-onset form of glycogen storage disease type IV (GSD IV) and is caused by biallelic pathogenic variants in GBE1. Advances in the understanding of the natural history of ... Full text Cite

A novel approach to characterize phenotypic variation in GSD IV: Reconceptualizing the clinical continuum.

Journal Article Front Genet · 2022 Purpose: Glycogen storage disease type IV (GSD IV) has historically been divided into discrete hepatic (classic hepatic, non-progressive hepatic) and neuromuscular (perinatal-congenital neuromuscular, juvenile neuromuscular) subtypes. However, the extent t ... Full text Link to item Cite

Quantitative trait mapping in Diversity Outbred mice identifies novel genomic regions associated with the hepatic glutathione redox system.

Journal Article Redox biology · October 2021 The tripeptide glutathione (GSH) is instrumental to antioxidant protection and xenobiotic metabolism, and the ratio of its reduced and oxidized forms (GSH/GSSG) indicates the cellular redox environment and maintains key aspects of cellular signaling. Disru ... Full text Cite

Genetic mapping of renal glutathione suggests a novel regulatory locus on the murine X chromosome and overlap with hepatic glutathione regulation.

Journal Article Free radical biology & medicine · October 2021 Glutathione (GSH) is a critical cellular antioxidant that protects against byproducts of aerobic metabolism and other reactive electrophiles to prevent oxidative stress and cell death. Proper maintenance of its reduced form, GSH, in excess of its oxidized ... Full text Cite

The effects of different doses of curcumin compound on growth performance, antioxidant status, and gut health of broiler chickens challenged with Eimeria species.

Journal Article Poultry science · November 2020 Supplementation of broiler diets with feed additives such as chemotherapeutic drugs and antibiotics has side effects, meat residues, and antibiotics resistance complications. Plant-derived natural compounds could be safe and easy substitutes for chemical a ... Full text Cite

The effects of L-Arginine supplementation on growth performance and intestinal health of broiler chickens challenged with Eimeria spp.

Journal Article Poultry science · November 2020 This study evaluated the effects of varying levels of L-arginine (Arg) on performance and intestinal health of broilers challenged with Eimeria. Cobb 500 male chicks (n = 720) were randomly distributed in a 5 × 2 factorial arrangement (6 replicates/12 bird ... Full text Cite

Effects of Inorganic Zn and Cu Supplementation on Gut Health in Broiler Chickens Challenged With Eimeria spp.

Journal Article Frontiers in veterinary science · January 2020 An experiment was conducted to evaluate the effect of different levels of inorganic copper and zinc on growth performance, intestinal permeability, intestinal lesion scores, oocyst shedding, antioxidant properties and bone quality in broilers challenged wi ...

Impact of Supplementary Amino Acids, Micronutrients, and Overall Diet on Glutathione Homeostasis.

Journal Article Nutrients · May 2019 Glutathione (GSH) is a critical endogenous antioxidant found in all eukaryotic cells. Higher GSH concentrations protect against cellular damage, tissue degeneration, and disease progression in various models, so there is considerable interest in developing ... Full text Cite

Heritability of the aged glutathione phenotype is dependent on tissue of origin.

Journal Article Mammalian genome : official journal of the International Mammalian Genome Society · October 2018 Glutathione is a ubiquitous antioxidant that protects cells against reactive oxygen species and other chemical stressors. Despite its functional importance, the impact of genetics on the glutathione system has yet to be fully appreciated. Here, we investig ... Full text Cite
