    摘要: The present invention provides a method of identifying a gene product. The method comprises providing a multiplicity of cells comprising a first gene product. Preferably, the first gene product is produced in the multiplicity of cells by expressing a first exogenous nucleic acid sequence encoding the first gene product. A library of second nucleic acid sequences encoding second gene products is then introduced into the multiplicity of cells. The second nucleic acid sequences are expressed in the multiplicity of cells to produce the second gene products such that the first gene product and at least one of the second gene products contact. The method further comprises causing a complex to form between the first gene product, an affinity molecule that binds the first gene product, and at least one of the second gene products, and subsequently retrieving the complex. At least one second gene product of the complex then is identified.

    摘要: The present invention provides a method of modulating neovascularization in an animal. The method comprises administering to the animal two or more nucleic acid sequences, each nucleic acid sequence encoding at least one angiogenesis-modulation factor that acts upon a different angiogenic process, such that the nucleic acid sequences are expressed to produce the angiogenesis-modulation factors to modulate neovascularization in the animal. Modulating neovascularization includes the induction of neovascularization or, in the alternative, the inhibition or reduction of neovascularization.

    摘要: The present invention provides a method of modulating the persistence of expression of a transgene in an at least E4&Dgr; adenoviral vector in a cell. In one embodiment, the method comprises contacting the cell with an at least E4&Dgr; adenoviral vector comprising (i) a transgene and (ii) a gene encoding a trans-acting factor, which is not from the E4 region of an adenovirus and which modulates the persistence of expression of the transgene. In another embodiment, the method comprises contacting the cell simultaneously or sequentially with (i) an at least E4&Dgr; adenoviral vector comprising a transgene and (ii) a viral vector comprising a gene encoding a trans-acting factor, which is not from the E4 region of an adenovirus and which modulates the persistence of expression of the transgene. In addition, the present invention provides a recombinant at least E4&Dgr; adenoviral vector for use in the method and a composition comprising the vector and a carrier therefor. Also provided by the present invention is a system for modulation of a recombinant at least E4&Dgr; adenoviral vector for use in the method and a composition comprising the system and a carrier therefor.

    摘要: A method of enriching a solution of an adenovirus comprising applying a mixed solution comprising an adenovirus and at least one undesired type of biomolecule to an anion exchange chromatography resin containing a binding moiety selected from the group consisting of dimethylaminopropyl, dimethylaminobutyl, dimethylaminoisobutyl, and dimethylaminopentyl and eluting the adenovirus from the chromatography resin. Also provided is a method of purifying an adenovirus from adenovirus-infected cells comprising lysing such cells, applying the lysate to a single chromatography resin, eluting the adenovirus from the chromatography resin, and collecting a fraction containing adenovirus that is substantially as pure as triple CsCl density gradient-purified adenovirus. The present method further provides a method of accurately quantifying the number of adenoviral particles in a solution of adenovirus comprising applying to and eluting from an anion exchange chromatography resin a sample solution of adenovirus, comparing the absorbance of the sample solution of adenovirus and the absorbance of a standard solution of adenovirus, and quantifying the number of adenoviral particles in the sample solution.

    摘要: The present invention provides a chimeric adenovirus fiber protein, which differs from the wild-type coat protein by the introduction of a nonnative amino acid sequence in a conformationally-restrained manner. Such a chimeric adenovirus fiber protein according to the invention is able to direct entry into cells of a vector comprising the chimeric fiber protein that is more efficient than entry into cells of a vector that is identical except for comprising a wild-type adenovirus fiber protein rather than the chimeric adenovirus fiber protein. The nonnative amino acid sequences encodes a peptide motif that comprises an epitope for an antibody, or a ligand for a cell surface receptor, that can be employed in cell targeting. The present invention also pertains to vectors comprising such a chimeric adenovirus fiber protein, and to methods of using such vectors.
