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.

Novel ALDH1A1 (aldehyde dehydrogenase 1 family member A1) Inhibitors for the Treatment of Cancer

This technology includes the identification and use of novel inhibitors of ALDH1A1 (aldehyde dehydrogenase 1 family member A1) for the treatment of multiple diseases, including cancer, inflammation, and obesity. ALDH1A1 is an enzyme that has a role in alcohol metabolism, and has been implicated in maintaining cancer stem cells. A high-throughput screen was conducted that identified novel ALDH1A1 inhibitors.

Use of beclin 1 Inhibitors, including 17-hydroxy Wortmannin, to Treat TRAIL-resistant Cancer

This technology includes the use of a beclin 1 inhibitor, 17-hydroxy Wortmannin, for the treatment of TRAIL-resistant colon cancer. TRAIL (TNF-related apoptosis-inducing ligand) binds to death receptors (DR4/DR5) and activates apoptosis in cancer cells. Multiple clinical trials have focused on promoting TRAIL-induced death but have had a lack of efficacy due to TRAIL resistance developing quickly in cancer cells. Recent work has found that this resistance may be mediated by a lack of activation of the apoptosis/autophagy regulator beclin 1.

Inhibition of Thioredoxin Reductase 1 (Trxr1) by Pyridine Compounds for Cancer Treatment

This technology includes the use of pyridines for anticancer treatment. A common feature of cancer cells is a high level of reactive oxygen species with a concomitant increase of two antioxidative systems to combat the toxicity: the glutathione and thioredoxin systems. Inhibiting either, or both, of these systems is a promising avenue to target cancer cells. Thioredoxin Reductase 1 (Trxr1) is an important selenoprotein in the thioredoxin antioxidative system which has been implicated as a potential anti-cancer target.

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.
