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.

Fibroblast Cell Lines Homozygous for Glucocerebrosidase (GBA1) Mutation N370S for the Screening of Small Molecules for Gaucher Disease Treatment

This technology includes two human fibroblast cell lines 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. Gaucher disease is a rare and heterogeneous disorder, caused by inherited genetic mutations in GBA1.

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).

SARS-CoV-2 Neutralizing Antibodies and Synthetic Nanobody Library Using a Humanized Llama Framework Region

NCATS has developed a highly diverse synthetic library that will allow for the rapid identification of novel nanobodies that bind to a wide arrange of target antigens. The humanized framework used to construct the library will facilitate the transition of lead candidates into patient studies. Several highly potent SARS-CoV-2 nanobodies (antibodies) have been identified and are available for further development.

NCATS is actively seeking licensing for the 1) a synthetic library and 2) the potent neutralizing antibodies with activity against SARS-CoV-2.

Monoclonal Antibodies for the Recognition of Oncogene Fusions and Alveolar Rhabdomyosarcoma (ARMS) Diagnosis

This technology includes monoclonal antibody (mAb) that binds to the junction region of the PAX3-FOXO1 and PAX7-FOXO1 fusion protein for the diagnosis of Alveolar Rhabdomyosarcoma (ARMS). Specifically, two monoclonal antibodies (PFM.1 and PFM.2) have been isolated that recognize the 92kDa bands found uniquely to the pediatric striated muscle tumors of the type Alveolar Rhabdomyosarcoma (ARMS) carrying the characteristic t(2;13)(q35;q14) or t(1;13)(p36;q14) chromosomal translocations.

Staphylococcus Epidermidis Isolates from Human Skin Samples for Use as Clinical Molecular Markers

This technology includes a catalog of commensal and pathogenic staphylococci from human skin for utilization as clinical molecular markers of skin conditions and infections. The study of microbial diversity of human skin in both healthy and disease states is important to develop tools to track infections, outbreaks, and multi-drug resistant organisms, particularly in atopic dermatitis, eczema and other microbial-associated infections. Commensal skin S. epidermidis have an open pan-genome and show considerable diversity between isolates.

Three-Dimensional Respiratory Epithelial Tissue Constructs With Perfusable Microvasculature

The invention provides two vascularized, multi-chip models for the alveoli and the small airway. Both models comprise a perfusable three-dimensional (3D) microvascular network consisting of human primary microvascular endothelial cells, fibroblasts, and pericytes with a differentiated lung epithelial layer exposed at the air-liquid interface (ALI) on top, built on a high-throughput, 64-chip microfluidic plate platform. The platform does not require the support of a permeable membrane and the epithelial cells are directly seeded on the perfused microvascular network.

Lymphoblastoid Cell Lines with a Specific Allele of ABCA7 Gene for the Screening of Small Molecules for Therapeutic Development

This technology includes lymphoblastoid cell lines from individuals genotyped as carrying the minor (G) allele of ABCA7 SNP rs113809142 [ss491752998; SNV-chr19-1007244], to be used for small molecule screening and eventual therapeutic development. The ABCA7 gene is the ATP-binding cassette, sub-family A (ABC1), member 7. It encodes a protein that is a transporter and has been associated with such diseases as neonatal respiratory failure and Asperger's syndrome. It is also known to play a role in phagocytosis of apoptotic cells by macrophages and may mediate cholesterol efflux.

DNA Methylation Based Non-invasive Blood Diagnostic Assay for Precision Cancer Detection and Classification

This technology includes a panel of 46 genomic loci of DNA methylation (represented by CpG dinucleotides on different chromosomes) with application in blood-based cancer screening. The markers robustly distinguish tumor from normal samples using 8 loci and classify 13 different tumor types. Using 39 loci, inventors were able to discriminate between individual tumor types or peripheral blood. In 4052 tumor samples from 13 tumor types, the true positive rate of classification was 91.4%.

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.
