  • Patent number: 6469142
    Abstract: In accordance with the present invention, there are provided nucleic acids encoding human NMDA receptor protein subunits and the proteins encoded thereby. The NMDA receptor subunits of the invention comprise components of NMDA receptors that have cation-selective channels and bind glutamate and NMDA. In one aspect of the invention, the nucleic acids encode NMDAR1 and NMDAR2 subunits of human NMDA receptors. In a preferred embodiment, the invention nucleic acids encode NMDAR1, NMDAR2A, NMDAR2B, NMDAR2C and NMDAR2D subunits of human NMDA receptors. In addition to being useful for the production of NMDA receptor subunit proteins, these nucleic acids are also useful as probes, thus enabling those skilled in the art, without undue experimentation, to identify and isolate related human receptor subunits.

  • Patent number: 6384018
    Abstract: Genes encoding Mycobacterium tuberculosis (M.tb) proteins were cloned into eukaryotic expression vectors to express the encoded proteins in mammalian muscle cells in vivo. Animals were immunized by injection of these DNA constructs, termed polynucleotide vaccines or PNV, into their muscles. Immune antisera was produced against M.tb antigens. Specific T-cell responses were detected in spleen cells of vaccinated mice and the profile of cytokine secretion in response to antigen 85 was indicative of a Th1 type of helper T-cell response (i.e., high IL-2 and IFN-&ggr;). Protective efficacy of an M.tb DNA vaccine was demonstrated in mice after challenge with M.bovis BCG, as measured by a reduction in mycobacterial multiplication in the spleens and lungs of M.tb DNA-vaccinated mice compared to control DNA-vaccinated mice or primary infection in naive mice.

  • Patent number: 6383768
    Abstract: This is a method for reproducing in vitro the RNA-dependent RNA polymerase activity associated with hepatitis C virus. The method is characterized in that sequences contained in NS5B are used in the reaction mixture. The terminal nucleotidyl transferase activity, a further property of the NS5B protein, can also be reproduced using this method. The method takes advantage of the fact that the NS5B protein, either purified to apparent homogeneity or present in extracts of overproducing organisms, can catalyze the addition of ribonucleotides to the 3′-termini of exogenous or endogenous RNA molecules. The invention also relates to a composition of matter that comprises sequences contained in NS5B, and to the use of these compositions for the set up of an enzymatic test capable of selecting, for therapeutic purposes, compounds that inhibit the enzymatic activity associated with NS5B.

  • Patent number: 6375929
    Abstract: The present invention relates to methods of gene therapy for inhibiting angiogenesis associated with solid tumor growth, tumor metastasis, inflammation, psoriasis, rheumatoid arthritis, hemangiomas, diabetic retinopathy, angiofibromas, and macular degeneration Gene therapy methodology is disclosed for inhibition of primary tumor growth and metastasis by gene transfer of a nucleotide sequence encoding a soluble form of a VEGF tyrosine kinase receptor to a mammalian host. The transferred nucleotide sequence transcribes mRNA and a soluble receptor protein which binds to VEGF in extracellular regions adjacent to the primary tumor and vascular endothelial cells. Formation of a sVEGF-R/VEGF complex will prevent binding of VEGF to the KDR and FLT-1 tyrosine kinase receptors, antagonizing transduction of the normal intracellular signals associated with vascular endothelial cell-induced tumor angiogenesis.

  • Patent number: 6372425
    Abstract: A process of purifying target molecules is described that involves the selection of ligands based on identifying, in real time, association and dissociation constants with a given target molecule; using this information to select at least one ligand that exhibit predetermined association and dissociation constants with a given target molecule; anchoring a quantity of ligand to an activated solid support; contacting a quantity of target molecules with the anchored ligand(s); removing low affinity target molecules from anchored ligand and eluting particularly pure target molecules.

  • Patent number: 6372183
    Abstract: Automated measurement apparatus and methods for automated drug screening procedures are provided. The apparatus is capable of initiating and measuring rapid or transient events, such as cell receptor and/or ion channel activity. In particular, the apparatus is capable of aligning with predetermined positions, one or more samples contained in a multi-well container, initiating the reaction with reagent addition and measuring a resultant attribute for a period of time. The apparatus can substantially continuously measure and record data corresponding to the measured attribute before, during and after initiation of the reaction so that a time course of the rapid or transient event may be determined. After the reaction(s) are complete in one or more wells of the multi-well container, the apparatus can align one or more different wells to be assayed with the predetermined position and repeat the cycle until a predetermined number of wells are assayed.

  • Patent number: 6369208
    Abstract: A method is provided for making synthetic capped RNAs. These compounds serve as substrates for the virally encoded endonuclease associated with influenza virus. We are able to assay for this unique and specific viral activity of cleavage of a capped RNA in vitro. Therefore, screening of inhibitors of this activity is possible. In addition, short non-extendible (due to their length or because of the modification of the 3′-end of the oligo, i.e. 3′-dA) RNAs are potent inhibitors of the cleavage of capped RNAs by influenza endonuclease. Finally, these compounds may be used to investigate viral and cellular mechanisms of transcription/translation or mRNA maturation.
