Novel Codon-Optimized MUT Gene Therapeutic for Methylmalonic Acidemia (MMA)

Methylmalonic Acidemia (MMA) is a metabolic disorder characterized by increased acidity in the blood and tissues due to toxic accumulation of protein and fat by-products resulting in seizures, strokes, and chronic kidney failure. A significant portion of MMA cases stem from a deficiency in a key mitochondrial enzyme, methylmalonyl-CoA mutase (MUT), required to break down amino acids and lipids. Currently, there are no treatments for MMA and the disease is managed primarily with dietary restriction of amino acid precursors and liver-kidney transplantation in severe cases.

Fibroblast Cell Lines (with L444P/RecNci1 Genotype) for the Screening of Small Molecules for Gaucher Disease Treatment

This technology includes two human fibroblast cell lines to be used to study the defects in GBA1 gene and protein and to screen small molecules for involvement in Gaucher disease. Glucocerebrosidase (GBA1 or GCase or beta-glucosidase) 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 in tissues, which is a major symptom of Gaucher disease.

In-vivo System to Interrogate the Functions of Mucous Membranes and Identify Mucin/Glycan Mimetics and JAK/STAT Inhibitors for the Treatment of Diseases of the Oral Cavity and Digestive Tract

This technology includes a Drosophila mutant strain that can be used as an in vivo model for diseases of the oral cavity and digestive tract (Sjogren's syndrome, colitis, colon cancer, inflammatory bowel disease), where the mucous membrane is disrupted or non-functional. This mutant lacks a mucous membrane and displays epithelial cell damage, uncontrolled cell proliferation and the up-regulation of conserved signaling pathways (JAK/STAT).

Systemic CRISPR Therapy for the Treatment of Inherited Diseases

This technology includes novel systemic adeno-associated virus (AAV)-mediated CRISPR gene therapy technology. While some diseases (e.g., retinal diseases) can be treated through local gene transfer, many diseases such as Duchenne Muscular Dystrophy (DMD) require systemic therapy. The CRISPR technology has two components, the Cas9 endonuclease, and the gRNA. To explore systemic CRISPR therapy, we co-delivered the AAV.Cas9 and AAV.gRNA vector to mdx mice, a mouse DMD model. Direct delivery to muscle yielded efficient gene correction.
