摘要:
A method for delivering an isolated polynucleotide to the interior of a cell in a vertebrate, comprising the interstitial introduction of an isolated polynucleotide into a tissue of the vertebrate where the polynucleotide is taken up by the cells of the tissue and exerts a therapeutic effect on the vertebrate. The method can be used to deliver a therapeutic polypeptide to the cells of the vertebrate, to provide an immune response upon in vivo translation of the polynucleotide, to deliver antisense polynucleotides, to deliver receptors to the cells of the vertebrate, or to provide transitory gene therapy.

摘要:
A gene that encodes an inhibitor of CDK4 has been discovered and its genomic nucleotide sequence has been identified. Susceptibility to certain cancers has been shown to be causatively related to the deletion of, or polymorphisms in, the CDK4I gene. The invention is therefore directed to the gene (CDK4I), the inhibitor protein, as well as therapeutic and diagnostic methods which utilize both the CDK4I gene and the CDK4I protein.

摘要:
The invention provides a method for diagnosis of, and determining a prognosis for, cancer causatively associated with derangements of chromosome 9p21. Underlying the invention is the discovery that such derangements have their genesis in deletions occurring centromeric to STS 3.21, most often including breakpoints in exon 8 and/or between exons 4 and 5 of the gene which codes for methylthioadenosine phosphorylase. As the cancer and tumor development advance, deletions in 9p21 progress centromerically from the genesis point toward the gene encoding p16. Thus, the method of the invention is performed by determining whether (a) portions of the 9p21 region including and telomeric to STS 3.21 are deleted; and (b) portions of the 9p21 region centromeric to STS 3.21 are deleted; wherein a positive finding in step (a) and a negative finding in step(b) are indicative of a cancer in an early stage of tumor development and a positive finding in step (b) is indicative of a cancer in an advanced stage of tumor development.
摘要:
The invention is directed to a method for treating both the early and late phases of allergic asthma by introducing naked polynucleotides which operatively encode for the asthma-initiating antigen into the host. The antigen-encoding polynucleotides are administered to host tissues which contain a high concentration of antigen presenting cells (e.g., skin and mucosa) relative to other host tissues. Expression of the asthma-initiating antigen encoding polynucleotides of the invention inside of antigen presenting cells (without substantial secretion therefrom) induces antigen tolerance while suppressing IgE antibody formation in the early phase of the disease, and also suppresses cytokine-mediated eosinophil accumulation in the late phase of the disease. Devices and compositions for use in the methods of the invention are also described.

The invention is directed to methods for introducing biologically active peptides into a host by administration of polynucleotides which operatively encode for the peptide of interest. In a preferred embodiment of the invention, a mammal is desensitized to an antigen, in particular an allergen, through administration to the mammal of polynucleotides which operatively encode the antigen. The antigen-encoding polynucleotides are administered to host tissues which have a high concentration of antigen presenting cells in them relative to other host tissues. The method is particularly useful in treating allergies because the allergen-encoding polynucleotides of the invention to induce tolerance while suppressing IgE antibody formation. Devices and compositions for use in the methods of the invention are also described.
摘要:
Combinations of polymerization, non-competitive hybridization and assay techniques is disclosed. In one aspect of the method, one member of a regular or anchored primer pair is modified to include a coupling agent capable of forming a tight bond (resistant to uncoupling in an alkaline denaturing environment) with a reactant. Competitive PCR is performed and the PCR products are coupled via the coupling agent to a reactant on the surface of a solid phase support. The bond between the reactant and the solid phase support in this and all embodiments is also resistant to uncoupling in an alkaline denaturing environment. In another aspect of the method, a primer is tightly coupled to the bound reactant and a polymerization of the competitor and target nucleic acids is performed on the solid phase. A third embodiment uses at least three primers, one of which is internal to the PCR templates and is bound to the solid phase support on which the entire PCR takes place. In the first two embodiments, sense strands are completely removed from solution with the bound antisense strands of the PCR products. Hybridization with sequence-specific probes is then performed in the absence of competition for binding by the sense strands. Sense strand removal and hybridization is optional in the third embodiment, where the bound three-primer PCR products can be detected by a detectible signal. Quantification of the target template may preferably be achieved in all embodiments by an enzyme-linked immunosorbent assay (ELISA), using ELISA data analysis software and standard curves.
