A Novel Therapeutic Vector for Hemoglobin Disorders

Investigators at the National Heart, Lung, and Blood Institute have designed a novel lentiviral vector as a potential gene therapy for sickle cell anemia and beta-thalassemia. The novel lentiviral vector encodes the beta-globin gene in a forward orientation and can produce 5-10 fold higher viral titer and 4-10 fold higher gene transfer efficiency to hematopoietic stem cells than reverse-oriented lentiviral vectors. In vivo studies conducted in rhesus macaques show beta-globin production after transplantation with this novel lentiviral vector.

SIRT1 KO Human Cell Lines Generated by CRISPR/Cas9-mediated DNA Editing

SIRT1, a NAD+-dependent protein deacetylase, is the most conserved member of the sirtuins family. Through deacetylation of a number of protein substrates that are important transcription factors or co-factors, SIRT1 regulates many vital biological processes such as metabolism, cellular stress response, stem cell pluripotency, and development.

Mouse Model for Study of Diabetic Nephropathy and Role of Soluble Epoxide Hydrolase

Diabetic nephropathy (DN) is the leading cause of renal failure and is characterized by proteinuria that progresses to renal inflammation and decline in the glornerular filtration barrier (GFB). Podocytes are specialized epithelia cells in the glomerular capsule that have a role in filtration of blood and maintaining the integrity of the GFB; dysfunction of these cells plays a significant role in the pathogenesis of DN. Soluble epoxide hydrolase (sEH) is a cytosolic enzyme whose inhibition has beneficial effects in inflammatory diseases.

Long Acting Therapeutic Conjugates with Evans Blue

This invention is a platform technology that pertains to the advantages of conjugating therapeutics to Evans Blue thus providing long lasting pharmacokinetic profiles by complexing with albumin. Notably, albumin bound therapeutic- or prodrug-Evans Blue conjugates provide a complex with a total molecular size above 60 kDa thus eliminating the risk for renal clearance. Interestingly, since albumin also crosses the blood-brain barrier and since all circulating Evans Blue is bound to albumin, Evans Blue bound therapeutics or prodrugs can also cross the blood-brain barrier.

Remotely Monitored Mouse Feeding Experimentation Device

How much does a mouse eat per day? If a researcher is conducting dietary studies, the answer is very important. For instance, obesity studies require accurate measures of feeding. Existing automated methods for taking feeding measurements are expensive and use specialized caging that is not compatible with typical vivarium colony racks. As a result, many researchers simply weigh food each day or two to determine how much food the mice ate. This is time-consuming, can be error prone, and provides a low temporal resolution view of feeding.

Capsid-Free AAV Vectors for Gene Delivery and Their Use for Gene Therapy

The invention concerns novel capsid-free AAV vectors that can be used for gene delivery and gene therapy applications. The invention provides for a linear nucleic acid molecule comprising in this order: a first adeno-associated virus (AAV) inverted terminal repeat (ITR), a nucleotide sequence of interest, and a second AAV ITR, wherein said nucleic acid molecule is devoid of AAV capsid protein coding sequences. The said nucleic acid molecule can be applied to a host at repetition without eliciting an immune response.

Reducing Bloodstream Neutrophils as a Treatment for Lung Infection and Inflammation

During lung infection, bloodstream neutrophils (PMNs) responding to infection travel to the airspace lumen. Although successful arrival of microbicidal PMNs to the airspace is essential for host defense against inhaled pathogens, excessive accumulation of PMNs in the lung contributes to the pathogenesis of several prevalent lung disorders, including acute lung injury, bronchiectasis, and COPD. Unfortunately, there is no treatment for controlling PMN accumulation in the lung.

Novel Activators of Pyruvate Kinase for the Treatment of Hemolytic Anemias

This technology includes the development and use of small molecule activators of pyruvate kinase (PK) for the treatment of inherited nonspherocytic hemolytic anemia, including PK deficiency. PK deficiency is caused by an inherited deficiency in an enzyme that reduces the lifespan of red blood cells. More than 150 unique mutations have been identified in the PK gene that lead to decreased activity in this essential enzyme in the glycolytic pathway. The prematurely lysed red blood cells can lead to jaundice, splenomegaly, and a hemolytic anemia.

Combination Therapy of Human Recombinant N-acetylgalactosamine-6-sulfate sulfatase (hrGALNS) and Chaperones for the Treatment of Mucopolysaccharidosis Type IVA

This technology includes the identification and use of a combination therapy consisting of human recombinant N-acetylgalactosamine-6-sulfate sulfatase (hrGALNS) and the pharmacological chaperone compounds Ezetimibe and Pranlukast for the treatment of Mucopolysaccharidosis Type IVA (MPS IVA). MPS IVA is a rare disease caused by mutations in the gene encoding the lysosomal enzyme N-acetylgalactosamine-6-sulfate sulfatase (GALNS). Currently, hematopoietic stem cell transplantation (HSCT) and enzyme replacement therapy (ERT) are available for patients with MPS IVA.
