  • Publication number: 20150011612
    Abstract: The present invention is based on the in vivo demonstration that RSV can be inhibited through intranasal administration of iRNA agents as well as by parenteral administration of such agents. Further, it is shown that effective viral reduction can be achieved with more than one virus being treated concurrently. Based on these findings, the present invention provides general and specific compositions and methods that are useful in reducing RSV mRNA levels, RSV protein levels and viral titers in a subject, e.g., a mammal, such as a human. These findings can be applied to other respiratory viruses.

  • Publication number: 20140073668
    Abstract: The present invention relates to the NQBS class of molecules. It is based, at least in part, on the discovery that a representative group of compounds have been observed to inhibit nuclear translocation of NF-?B subunits. Without being bound by any particular theory, this inhibition of nuclear translocation may be mediated by either (i) binding of the NQBS or related compound to the C-terminus of the RHD, which specifically mediates the nuclear internalization; or (ii) NQBS-mediated stabilization of the dimer/I?B complex, disallowing dissociation of the active NF-?B monomers, and thus, inhibiting the generation of the subunits necessary to enter the nucleus. The NQBS class of molecules, and related molecules, may be used in therapeutic applications where inhibition of NF-?B translocation is beneficial, including but not limited to the treatment of cancer, autoimmune disorders, and inflammatory states.

    Abstract: The present invention is based on the development of a dual promoter system (preferably a RNA pol I-pol II system) for the efficient intracellular synthesis of viral RNA. The resultant minimal plasmid-based system may be used to synthesize any RNA virus, preferably viruses with a negative single stranded RNA genome. The viral product of the system is produced when the plasmids of the system are introduced into a suitable host cell. One application of the system is production of attenuated, reassortant influenza viruses for use as antigens in vaccines. The reassortant viruses generated by cotransfection of plasmids may comprise genes encoding the surface glycoproteins hemagglutinin and neuramimidase from an influenza virus currently infecting the population and the internal genes from an attenuated influenza virus. An advantageous property of the present invention is its versatility; the system may be quickly and easily adapted to synthesize an attenuated version of any RNA virus.

  • Patent number: 6620597
    Abstract: A method for generating and amplifying closed circular DNA having a specific sequence in vitro in a cell-free system is disclosed. Prior to the invention of this method, closed circular DNA could only be amplified in vivo in appropriate host cells. The essence of the method is the inclusion of a thermostable DNA ligase in a PCR reaction. This procedure is referred to as ligation-during-amplification (LDA), in which the fully extended DNA strands are ligated by the DNA ligase and used as templates for subsequent amplification. Closed circular DNA having a specific sequence can be selectively amplified exponentially by the use of two sequence-specific primers in the LDA reaction. In addition, one or more site-specific mutations can be introduced into a closed circular DNA by the use of one or more mutagenic primers in the LDA reaction. Various thermostable DNA polymerases and thermostable ligases can be used for LDA amplification.

  • Patent number: 6589732
    Abstract: The present invention is directed to isolated transducing phages, methods of isolating transducing phages, and methods of using transducing phages including, for instance, transferring at least one nucleic acid fragment from a donor microbe to a recipient microbe, and producing a secondary metabolite from a microbe. The transducing phages typically have a broad host range, and transduce microbes in the Order Actinomycetales, in particular in the Family Streptomycetaceae, including Streptomyces coelicolor, Streptomyces lividans, Streptomyces venezuelae, Streptomyces avermitilis, and Saccharopolyspora erythraea. The transducing phages can be specialized transducing phages or generalized transducing phages.

  • Patent number: 6544507
    Abstract: A viral DNA construct, and virus encoded thereby, is provided having one or more tumor specific transcription factor binding sites in place of one or more wild type transcription factor binding sites operatively positioned in the promoter region which controls expression of early genes responsible for viral nucleic acid replication. Preferred constructs place the tumor specific transcription factor binding sites in operative relation to DNA polymerase, DNA terminal protein and/or DNA binding protein. Compositions and constructs contained therein are provided, particularly for use in therapy. Methods of treating patients for neoplasms are also provided.

  • Patent number: 6500611
    Abstract: An innovative detection system for detecting small numbers of target analytes is disclosed. This system provides a novel method for attaching multiple copies of reporter groups to a single site on an analyte of interest. This system preferably comprises a virus capsid enclosing multiple detectable reporter groups, and a linking molecule which is capable of linking the capsid to the analyte of interest.

  • Publication number: 20020155532
    Abstract: The gene of human acidic fibroblast growth factor 155 (haFGF 155) has been obtained by chemical synthesis. The nucleotide sequence of haFGF 155 gene has been deduced on the basis of haFGF 155 amino acid sequence as described in the literature. The amino acid sequence of the synthesized haFGF 155 does not differ from those described in the literature. The nucleotide sequence of haFGF gene differs from those described previously. For chemical synthesis of haFGF 155 gene, codons were used which are the ones most often used by E. coli in highly expressed E. coli proteins. A plasmid with haFGF 155 (phaFGF 155) gene was obtained and was used to transform E. coli. Production of haFGF 154 protein was achieved by cultivation of the producer strain under conditions which slow down the lytic development of lambda phage. The haFGF 154 protein accumulated in culture medium in a soluble condition as a result of the producer strain cells lysis by the lambda phage.

  • Publication number: 20020132347
    Abstract: a method is provided for detecting a presence of HIV virus in a sample comprising: taking a culture of recombinant cells which (a) are capable of cell division, (b) express CD4 receptor and one or more additional cell surface receptors necessary to allow the HIV virus to infect, (c) enable the HIV virus to replicate and infect the noninfected cells in the cell culture, and (d) comprise a reporter sequence introduced into the recombinant cells comprising a reporter gene whose expression is regulated by a protein specific to HIV viruses which is expressed from a genome of an HIV virus upon infection of the recombinant cell by the HIV virus; contacting the cell culture with a sample to be analyzed for the presence of HIV virus in the sample; and detecting a change in a level of expression of the reporter gene in cells in the recombinant cell culture.
