Abstract: The present invention is generally drawn to novel isolated therapeutic agents, termed resolvins, generated from the interaction between a dietary omega-3 polyunsaturated fatty acid (PUFA) such as eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA), oxygenases and the analgesic aspirin (ASA). Surprisingly, careful isolation of compounds generated from the combination of components in an appropriate environment provide di- and tri-hydroxy containing derivatives of EPA and DHA containing compounds having unique structural and physiological properties. The present invention therefore provides for many new useful therapeutic di- and tri-hydroxy derivatives of EPA or DHA (resolvins of the E series and D series) that diminish, prevent, or eliminate gastrointestinal conditions, for example, such as colitis. The present invention also provides methods of use, methods of preparation, and packaged pharmaceuticals for use as medicaments for the compounds disclosed throughout the specification.

Abstract: The present invention is directed to methods for the identification and uses of a receptors that interact with anti-inflammatory compounds derived from eicosapentaenoic acid (EPA). The receptors are of the G-protein coupled receptor (GPCR) family, and are useful to screen candidate substances for anti-inflammatory activity, especially substances that are analogs of EPA. Such analogs are termed “resolvins”; and are typically di- and tri-hydroxy EPA analogs. One analog herein denoted Resolvin E1 was identified in humans and prepared by total synthesis. In nanomolar range Resolvin E1 reduces dermal inflammation, peritonitis, dendritic cells (DCs) migration and IL-12 production. Also described herein is a receptor denoted Reso ER1 that interacts with Resolvin E1 to attenuate cytokine induced activation of inflammatory pathways mediated by transcription factor (NF)-kB. Treatment of DCs with small-interfering RNA specific for ResoE1 eliminated the ligand's ability to regulate IL-12.

Abstract: The present invention provides a knockout animal artificially modified to inhibit ?-TTP gene expression. This animal is useful as a tool for understanding mechanisms for the development of familial isolated vitamin E deficiency and other diseases induced by oxidative stress (e.g., arteriosclerosis, diabetes). It is also useful as a tool for developing a therapeutic agent for these diseases.

Abstract: Provided is DNA encoding a squalene epoxidase-promoting factor having a function of controlling the activity of squalene epoxidase, which is the rate-limiting enzyme in the cholesterol biosynthesis.
