This technology includes a precise measurement assay of cellular FMRP levels in patients, which can assist in the diagnosis and assess the severity of Fragile X syndrome (FXS). FXS is an X-linked disorder that produces intellectual disability, cognitive impairment, epilepsy, depression and anxiety. FXS is caused by mutations in the Fragile X Mental Retardation-1 (FMR1) gene that result in the absence or a loss of function of its protein product, FMRP.

This technology includes a group of eight AMPK activating compounds to be further developed for the treatment of Niemann Pick Type C (NPC) disease. Through the recent molecular biology and pharmacological experiments, we have identified the cyclodextrin which directly binds to beta-subunits of AMP-activated protein kinase (AMP), resulting in subsequently activations of AMPK and AMPK linked autophagy, and restoration of autophagy function that is impaired in the NPC cells.

This technology includes the generation and use of human induced pluripotent stem cell (iPSC) lines that can be used to study and screen potential therapeutics for lysosomal storage diseases (LSDs). LSDs are a group of 50 genetic disorders caused by mutations in the genes encoding lysosomal enzymes and proteins. Although various therapeutic approaches exist, most cases of LSDs are not effectively treated due to a lack of therapeutics (including stem cells and recombinant proteins).

This technology includes the use of a novel formulation for an engineered version of Fibroblast Growth Factor 1 (FGF1), TTHX1114, that can be used to accelerate regeneration of the corneal endothelium after surgical lesions. FGFs are well-established regulators of migration and proliferation of corneal endothelial cells (CECs).

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.

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.

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.

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.

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.

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.
