Isolation of Hybridomas Producing Monoclonal Antibodies (MAbs) Inhibitory to Human CYP2J2

The National Institutes of Health announces three specific monoclonal antibodies that strongly inhibit and/or immunoblot the human cytochrome P450 2J2 (CYP2J2).

Cytochrome P450s catalyze the NADPH-dependent oxidation of arachidonic acid to various eicosanoids found in several species. The eicosanoids are biosynthesized in numerous tissues including pancreas, intestine, kidney, heart and lung where they are involved in many different biological activities.

A Tet-Regulated Mouse Model for Cataract

Cataract is the most common cause of blindness worldwide, with an estimated 25 million blind and 119 million visually impaired individuals worldwide. Over 20 million adults in the US alone are currently diagnosed with cataracts making this disease a major health concern. The incidence of cataract increases with age and a number of etiologic factors have been proposed in the pathogenesis of age-related cataract in humans including genetic factors, environmental factors and metabolic and biochemical changes in the crystalline lens.

Regulation of RNA Stability

This invention relates to the discovery that tristetraprolin (TTP) can promote the poly(A)RNase (PARN) mediated deadenylation of polyadenylated substrates containing AU-rich elements (AREs). As one aspect of the invention, the inventors have developed a cell free system that may be used for the purposes of assessing the effects of the various system components or their derivatives (i.e. AREs, PARN, or TTP) on the deadenylation process or the effects of various test agents on the deadenylation process.

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.

Antagonists of Hyaluronan Signaling for Treatment of Airway Diseases

Airway diseases, such as Asthma and Chronic Obstructive Pulmonary Disease (COPD), constitute a major health burden worldwide. It is estimated, for example, that nearly 15.0% of the adult population in the US are affected with such diseases, and the economic cost burden is over $23 billion annually. Unfortunately, the current options for treatment of such diseases are quite limited, consisting only of bronchodilators and inhaled steroids. The need for a novel and more effective class of therapeutics agents is imperative.

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.

Peanut therapeutics and diagnostics to treat severe food allergies

Up to 10% of the US population suffers from food allergies, with more than 40% of those experiencing life-threatening anaphylaxis. Peanut is one of the most common food allergens that give rise to persistent IgE-mediated food allergy. Oral immunotherapy (OIT) is used to reduce sensitivity to an allergen through repeated, small-dose exposure to the allergen. However, only a subset of patients develop a sustained response to the allergen and OIT carries notable side effects. 

A BL21 (ED3) Codon Plus Competent Cell-derived Bacterial Strain for Research Use

This technology includes a bacterial strain derived from BL21 (ED3) CodonPlus Competent Cells containing an expression vector for human POLR2C gene for research purposes. The bacterial strain can be used to produce the full-length human RNA polymerase II subunit, RPB3 protein, which can be in turn isolated and purified.

Developing a Stable Cell as a Screening Tool for Environmental Chemicals

This technology includes a stable cell line (293T2-PGC) which has an intact PGC-1 alpha/ERR-alpha pathway to screen for environmental chemicals. The estrogen-related receptor alpha (ERR-alpha) and proliferator-activated receptor gamma coactivator - 1alpha (PGC-1 alpha) play critical roles in the control of several physiological functions, including the regulation of genes involved in energy homeostasis. However, little is known about the environmental chemicals that could disrupt or modulate this pathway leading to adverse health effects.

p300 KO HEK293T Cell Line for Multiple Research Applications

This technology includes p300 KO HEK293T cells using crispr/cas9 mediated gene editing technology to be used for various research applications. We showed that p300 deficient cells have impaired glycolysis and are hypersensitive to glucose depletion-induced cell death. p300 is one of major transcriptional co-activators that regulates gene transcription as a histone acetyltransferase. Recent studies reveal that it functions as "writer" for a variety of lysine acylations, including acetylation, crotonylation, butryrylation, 2- hydroxyisobutyrylation, and succinylation.
