摘要:
In one embodiment, this invention provides methods of treating mammalian cancer or hyperproliferative cells, said method comprising contacting said cells with a tumor suppressor protein or tumor suppressor nucleic acid and also contacting said cell with at least one adjunctive anti-cancer agent. The invention also provides for a pharmacological composition comprising a tumor suppressor protein or a tumor suppressor nucleic acid and at least one adjunctive anti-cancer agent, and a kit for the treatment of mammalian cancer or hyperproliferative cells.
摘要:
The present invention provides a method for the treatment of lung cancer through the use of a recombinant gene therapy vector having a transgene encoding interferon. In particular it is noted that interferon when expressed by a recombinant gene therapy vectors possesses properties not associated with exogenously-manufactured interferon proteins. The present disclosure thus provides a method useful in the treatment of lung tumors such as mesothelioma, using a recombinant gene therapy vector having a transgene encoding interferon.
摘要:
A method and pharmaceutical composition for the treatment of cancer using a gene delivery system, such as a viral vector delivery system, comprising a therapeutic gene such as p53 or a retinoblastoma tumor suppressor gene wherein the gene delivery system is formulated in a buffer comprising a delivery-enhancing agent such as ethanol or a detergent.
摘要:
This invention provides a recombinant adenovirus expression vector characterized by the partial or total deletion of the adenoviral protein IX DNA and having a gene encoding a foreign protein or a functional fragment or mutant thereof. Transformed host cells and a method of producing recombinant proteins and gene therapy also are included within the scope of this invention. Thus, for example, the adenoviral vector of this invention can contain a foreign gene for the expression of a protein effective in regulating the cell cycle, such as p53, Rb, or mitosin, or in inducing cell death, such as the conditional suicide gene thymidine kinase. (The latter must be used in conjunction with a thymidine kinase metabolite in order to be effective).

摘要:
This invention provides methods of regulating gene expression. An aptamer is positioned in a nucleic acid molecule along with a sequence encoding a transcriptional regulatory polypeptide. The aptamer disrupts translation of the transcriptional regulatory polypeptide when contacted with an aptamer-binding ligand. Gene expression levels can be either increased or decreased by the disclosed methods, depending on whether the transcriptional regulatory polypeptide is a repressor or activator, and the degree of the effect is dependent upon the dose of the ligand. Nucleic acid molecules, expression cassettes, expression vectors and cells useful in the gene regulation methods are also provided.
摘要:
The present invention provides a method for the treatment of “interferon resistant” tumors (i.e., tumors resistant to treatment with exogenously-administered interferon polypeptide) through the use of a non-replicating agent which induces human cells to express interferon species. In particular it is noted that inducing interferon expression in the patient's body possesses properties not associated with exogenously-produced intravenously-administered interferon proteins. The present invention further provides compositions useful in the treatment of cancer resistant to treatment with exogenous interferon polypeptide, by using a non-replicating agent which induces human cells to express interferon species, e.g., an antigenic, replication-deficient virus optionally carrying an interferon transgene.

摘要:
A method for transducing a pathologic hyperproliferative mammalian cell is provided by this invention. This method requires contacting the cell with a suitable retroviral vector containing a nucleic acid encoding a gene product having a tumor suppressive function. Also provided by this invention is a method for treating a pathology in a subject caused by the absence of, or the presence of a pathologically mutated tumor suppressor gene.
