The NCGC BioPlanet: A Computational Algorithm to Display Networks in Three Dimensions

This technology includes a novel computational algorithm and software implementation to map and display biological pathways and their relationship on the surface of a globe in a three-dimensional space. Currently, biological pathways and genes are represented as two-dimensional networks, which is not effective for displaying complicated relationships between pathways and genes.

Creation and Use of 12-LO inhibitors (4-((2-hydroxy-3-methoxybenzyl)amino)benzenesulfonamide derivatives) for the Treatment of Diabetes and Large Platelet-Derived Clots

This technology includes the discovery and use of novel selective 12-LO (lipoxygenase) inhibitors, 4-((2-hydroxy-3-methoxybenzyl)amino)benzenesulfonamide derivatives, for attenuating large clots and for the treatment of Type 1/2 diabetes. A 12-LO inhibitor could be a potent intracellular approach to block platelets from forming large clots in response to vessel injury or activation of the coagulation pathway, either due to diabetes and/or cardiovascular disease. Blocking clot formation can significantly decrease the occurrence of myocardial infarction and death.

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.

Functional Brain Region-Specific Neural Spheroids for Modeling Neurological Diseases and Therapeutics Screening

3D spheroids have emerged as powerful drug discovery tools given their high-throughput screening (HTS) compatibility. The present invention presents a method for generating functional neural spheroids with differentiated human induced pluripotent stem cell (hiPSC)-derived neurons and astrocytes at cell type compositions mimicking specific regions of the human brain.

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.

Aberrant Post-translational Modifications (PTMs) in Methyl- and Propionic Acidemia and the Construction of a Novel Sirtuin (SIRT) Gene to Metabolize PTMs

Isolated Methylmalonic Acidemia (MMA) and the related disorder Propionic Acidemia (PA) comprise a relatively common and heterogeneous group of inborn errors of metabolism. NHGRI scientist discovered that in isolated MMA, a novel inhibitory PTM, methylmalonyllysine, is generated and inactivates protein targets through the failure of SIRT-mediated deacylation, and identified a series of antibodies for PTM specificity.

High Concentration Methylcobalamin (Me-Cbl) or Combination of Methyl- and Hydroxocobalamin (Me/OH-Cbl) for the Treatment of Cobalamin C Deficiency and Related Disorders

Cobalamin C deficiency (cblC), caused by mutations in MMACHC, is the most common inborn error of intracellular vitamin B12 metabolism. NHGRI scientist have generated a number of Mmachc knockout mouse models. The cblC mice present with early lethality, recapitulate the neurological phenotype seen in patients, and have enabled proof of concept testing with traditional hydroxocobalamin formulations and doses. The scientist have also developed a novel combination of hydroxo- and methylcobalamin, having superior performance to traditional hydroxocobalamin only treatment.

Improved Propionyl-CoA Carboxylase Alpha (PCCA) Alleles in Mouse Models for the Study of Propionic Acidemia (PA) and its Potential Treatments

Propionic acidemia (PA) is an autosomal recessive metabolic disorder caused by mutations in either PCCA or PCCB. The products of these genes form the alpha and beta subunits of the enzyme propionyl-Co A carboxylase (PCC), a critically important mitochondrial enzyme involved in the catabolism of branched chain amino acids. NHGRI scientist have developed new mouse models that more closely mimic the nature of mutations seen in patients, such as missense mutations, small insertion and deletions, splicing defects, and frameshift changes.

Mmut p.G715v/p.G71 Knock-ln Methylmalonyl-CoA Mutase (Mmut) Allele Mouse Models for the Study of Methylmalonic Acidemia (MMA)

Isolated Methylmalonic Acidemia (MMA) comprises a relatively common and heterogeneous group of inborn errors of metabolism. In order to create mouse models of MMA to resemble the pathogenic mutations seen in patients, the NHGRI scientist used genome editing to generate new mutants of Mmut allele -p.G715V. This allele recapitulates a missense mutation seen in multiple patients with the disorder. Of note and emphasis is the fact that there are no transgene cassettes or other alternations to the Mmut locus in these new mouse models.

Mmut P.Pro207_Lysl10del/P.Pro207_Lysl10del Knock-In Methylmalonyl-CoA Mutase (Mmut) Allele Mouse Models for the Study of Methylmalonic Acidemia (MMA)

Isolated Methylmalonic Acidemia (MMA) comprises a relatively common and heterogeneous group of inborn errors of metabolism. In order to create mouse models of MMA to resemble the pathogenic mutations seen in patients, the NHGRI scientist used genome editing to generate new mutants of the Mmut allele -p.Pro207 _Lys210del. In order to create mouse models of MMA to resemble the pathogenic mutations seen in patients, the NHGRI scientist used genome editing to generate new mutants of Mmut allele -p.Pro207 _Lys210del. This allele recapitulates a 12-nucleotide deletion in exon 3 of Mmut.
