Development of a Therapy for the Treatment of Zellweger Spectrum Disorder

This technology includes a method for selecting a therapeutic effective amount of one of two compounds (including naltriben and naltrin) for the treatment of Zellweger Spectrum Disorder (ZSD), or any disease associated with peroxisome dysfunction. The compounds were identified using a cell-image based high-content screening (HCS) assay to identify small molecules that enhance peroxisome assembly in immortalized skin fibroblasts obtained from a ZSD patient.

Development and Use of O-linked beta-N-acetylglucosamine (O-GlcNAc) Transferase (OGT) Inhibitors for Multiple Conditions, Including Cancer

This technology includes the development and use of small molecules that inhibit O-linked beta-N-acetylglucosamine (O-GlcNAc) transferase (OGT) for a variety of pathologies, including Alzheimer's disease, cancer, cancer, diabetes, and neurodegenerative disorders the treatment of cancer and as a potential antiviral. OGT is a ubiquitous enzyme that catalyzes the transfer of N-acetylglucosamine (GlcNAc) to the serine or threonine residues of nuclear and cytoplasmic proteins.

Discovery of Proteasome Inhibitors to Target PMP22 Gene Expression for the Treatment of Charcot-Marie-Tooth Disease Type 1A

This technology includes the use of proteasome inhibitors, such as Bortezomib, for the treatment of the most prevalent form of Charcot-Marie-Tooth disease type 1A (CMT1A). Duplication of the peripheral myelin protein 22 (PMP22) gene, normally involved in myelination of the peripheral nervous system, is the causative agent in most forms of CMT1A. A drug discovery program was initiated and found that proteasome inhibitors can be used to target PMP22.

Mouse Model of Cobalamin A (cblA) Class Isolated Methylmalonic Acidemia (MMA) to Study New Therapies

Isolated Methylmalonic Acidemia (MMA) comprises a relatively common and heterogeneous group of inborn errors of metabolism. Most affected individuals display severe multisystemic disease characterized by metabolic instability, chronic renal disease, and neurological complications. Patients with the cobalamin A (cblA) subtype of MMA can have variable presentations, spanning the full spectrum of MMA associated symptoms and pathology, yet always harbor an element of clinical and biochemical responsiveness to injectable vitamin B12.

Gene Therapy for Cobalamin C Deficiency (cblC) with Viable Mouse Models

Cobalamin C deficiency (cblC) is the most common inborn error of intracellular cobalamin metabolism and is caused by mutations in MMACHC, a gene responsible for processing and trafficking dependent enzymes: intracellular cobalamin, resulting in elevated methylmalonic acid and homocysteine and methionine deficiency. Disease manifestations include growth failure, anemia, cardial defects and progressive blindness.

Human Fibroblast Cell Lines from Patients with Gangliosidosis Diseases for the Screening of Disease Therapeutics

This technology includes cell lines from patients with gangliosidosis diseases for the screening of potential therapeutics. Gangliosidosis contains different types of lipid storage disorders caused by the accumulation of lipids known as gangliosides. GM1 gangliosidosis is an ultra-rare lysosomal storage disorder caused by mutations in galactosidase beta 1 (GLB1) that result in a deficiency of beta-galactosidase. GM2 gangliosidoses are a group of autosomal recessive lysosomal storage disorders caused by accumulation of GM2 ganglioside due to the absence or near absence of B-hexosamindase.

Human Fibroblast Cell Lines Heterozygous for Glucocerebrosidase (GBA1) Mutation N370S for the Study of Neurodegenerative Disorders and their Treatments

This technology includes six cell lines for the study of Glucocerebrosidase (GBA1) mutations which could be used for the evaluation and eventual treatments for conditions such as Gaucher's disease and Parkinson's disease. GBA1 is a lysosomal enzyme, responsible for breakdown of a fatty material called glucocerebroside (or glucosyl ceramide). Deficiency or malfunction of GBA1 leads to the accumulation of insoluble glucocerebrosides (derived mostly from ingested red and white blood cell membranes) in tissues, which is a major symptom of Gaucher disease.

Mouse Model Created Using Glucocerebrosidase-Deficient Neuronal Cell Line to Study Gaucher Disease Pathophysiology and Evaluate New Therapies

This technology includes a high-yield, easy-to-culture mouse neuronal cell model with nearly complete glucocerebrosidase deficiency representative of Gaucher disease (GD) to study pathophysiology and evaluate new therapies. GD is an autosomal recessive lysosomal storage disorder caused by loss-of function mutations in the GBA1 gene, which codes for the lysosomal hydrolase glucocerebrosidase (GCase).

Mouse Model of Hutchinson-Gilford Progeria Syndrome (HGPS) and Vascular Abnormalities (G608G) mutated form of human LNMA) for Therapeutic Development

Children with Hutchinson-Gilford progeria syndrome (HGPS) suffer from acceleration of certain aging symptoms, mainly cardiovascular disease that generally leads to death from myocardial infarction and/or stroke. The cause of HGPS has been discovered to be a de novo point mutation in lamin A (LNMA) gene. NHGRI Scientist have generated a transgenic mouse model of HGPS. This mouse carries a bacterial artificial chromosome (BAC) with a De novo mutation 1824 C to T (G608G) mutated form of human LNMA.

Human Cell Lines with NGLY1 Mutations for the Study of NGLY1 Deficiency and Therapeutic Development

Congenital disorders of glycosylation (CDGs) are a group of inborn errors characterized by abnormalities in the process of glycosylation of biomolecules. Although more than 100 different CDGs have been reported, only one has been thoroughly described, namely NGLY1 deficiency or NGLY1-CDG. NGLY1 encodes N-glycanase 1, an enzyme involved in the cytosolic degradation of misfolded glycoproteins and other glycoproteins bound for degradation.
