Novel ACRV1/ALK2 Inhibitors and Methods for Inhibiting BMP Signaling for the Treatment of Fibrodysplasia Ossificans Progressiva (FOP)

This technology includes the identification and use of novel ACRV1/ALK2 inhibitors for the treatment of fibrodysplasia ossificans progressiva (FOP), an autosomal-dominant rare disease that affects one person in every 1-2 million. FOP is characterized by malformation of the great (big) toes during embryonic development and by progressive heterotopic endochondral ossification (HEO) postnatally, which leads to the formation of a second skeleton of heterotopic bone.

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.

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.

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.

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.

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.

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.

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.
