Estrogen-related Receptor (ERR) and Proliferator-activated Receptor Gamma Coactivator (PGC)/ERR Reporter Stable Cell Lines

The estrogen-related receptor alpha (ERRalpha) and proliferator-activated-receptor-gamma coactivator-1alpha (PGC-1alpha) play major roles in transcriptional control of cellular energy metabolism. In particular ERRs are required for the response to various environmental challenges that require high energy levels by the organism. As central regulators of energy homeostasis, ERRs may also implicate in the etiology of metabolic disorders, such as type 2 diabetes and metabolic syndrome.

Leucine Rich Repeats and Calponin Homology Containing Protein 4 (Lrch4)-deficient Mouse

Leucine rich repeats and calponin homology containing protein 4 (Lrch4) is a gene that encodes a protein predicted to have a C-terminal transmembrane domain, a calponin homology domain, and 5-8 leucine rich repeats (LRRs). We silenced Lrch4 in RAW 264.7 macrophages as well as CD14-MD2-TLR4-HEK293 cells and found that Lrch4 knockdown attenuates responsiveness of cells to LPS and other pathogen-associated molecules. These findings suggest that Lrch4 is a regulator of the innate immune response.

Mouse Strain CAR-KO C3H/HeNCrl, Deletion of Nuclear Xenobiotic Receptor CAR

CAR (nuclear constitutive active receptor) is a member of the nuclear receptor superfamily, and is a key regulator of xenobiotic and endobiotic metabolism. It is primarily responsible for sensing foreign toxic substances and in response up regulating the expression of proteins involved in the detoxification and clearance of these substances from the body. CAR is constitutively active in the absence of a ligand but is regulated by both agonists and inverse agonists.

Novel Genetic Tristetraprolin (TTP) Knock-in Mouse

Tristetraprolin (TTP) is the prototype member of a small family of RNA binding proteins that bind to specific types of AU-rich elements in the 3'UTRs of target mRNAs and promote their rapid turnover. One of the targets destabilized by TTP is Tumor necrosis factor alpha (TNF). TNF has long been a target of anti-inflammatory drug development, in which recombinant protein molecules based on TNF antibodies or TNF receptors have been used to bind directly to TNF and inactivate it.

Immunological Detection of Free Radicals In Animals and In Vitro

Electron Spin Resonance (ESR) is an universal, specific tool for the detection of free radicals in biological systems. Its application to the investigation of free radicals from whole animals, organs, and cells has been made possible by the spin-trapping technique. In a Spin-trapping experiment, a spin trap such as DMPO (5,5-dimetryl-1-pyrroline N-oxide) reacts specifically with one or more types of free radical to form radical-derived nitrone adducts that are much more stable than the original free radicals.

Prevention or Treatment of Viral Infections by Inhibition of the Histone Methyltransferases EZH1/2

Herpes simplex viral infections, including herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), are exceptionally common worldwide. These viruses establish lifelong persistent infections with cycles of lytic reactivation to produce recurrent diseases including oral and genital lesions, herpetic keratitis/blindness, congenital-developmental syndromes, and viral encephalitis. Infection with HSV-2 increases the rate of human immunodeficiency virus (HIV) transmission in coinfected individuals. DNA replication inhibitors are typically used to treat herpesvirus infections.

A Genetic System in Yeast for Functional Identification of Human p53 Mutations

Mutations in the p53 gene are associated with 50% of all cancers and nearly 80% of the p53 mutations are missense changes. We have developed genetic assays based in yeast that can functionally categorize expressed p53 mutant proteins. The combined assays are referred to as the FIP53 system. Because human p53 cDNA can be conveniently cloned in yeast, the FIP53 system provides a rapid and sophisticated system for the functional analysis of p53 mutants. Four categories of mutations have already been identified.

Three-Dimensional Curved Catheter for Right Atrial Appendage Traversal

Available for licensing and commercial development is a three-dimensionally configured curved catheter for safe traversal of the right atrial appendage (RAA). The device is configured to optimize one-way access of the pericardial space through the right atrium and into the RAA reducing the risk of coronary lacerations. Specifically the curved catheter is best described in three segments: a proximal segment, a transitional segment and a distal segment; the transition segment having a clockwise spiral shaped curvature.

Tristetraprolin (TTP) Plasmid Vectors for Human and Mouse TTP

Tristetraprolin (TTP) is involved in the physiological regulation of the secretion of at least two important cytokines, tumor necrosis factor alpha (TNF) and granulocyte-macrophage colony-stimulating factor (GM-CSF). TTP exerts its effects by directly binding to the mRNAs encoding these proteins and destabilizing them, resulting in less secretion. Conversely, TTP deficiency results in an excess of both cytokines, leading to a systemic inflammatory syndrome.

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.
