摘要:
The present invention encompasses improved methods and materials for the delivering of antisense, triplex, and/or ribozyme oligonucleotides intracellularly, and RNA polymerase III-based constructs termed 'oligonucleotide generators' to accomplish the delivery of oligonucleotides. Also encompassed by the present invention are methods for screening oligonucleotide sequences that are candidates for triplex formation.
摘要:
Oligomers which inhibit expression of a collagen gene are described. It is believed that each oligomer, when introduced into a cell, forms a transcription-inhibiting complex composed of the oligomer and the collagen-gene promoter region. The oligomer, preferably a phosphorothioate deoxyoligonucleotide or a ribonucleotide, preferably binds in the antiparallel orientation to the polypurine strand of a polypurine-polypyrimidine region of the promoter region of a mammalian α1(I) collagen gene.

Methods for modulating the expression of genes are disclosed comprising selecting a portion RNA coded by the gene, said RNA portion having subportions forming a secondary structure, and contacting the RNA with oligonucleotide or oligonucleotide analog which can bind with at least one said subportions of the RNA. In accordance with the preferred embodiments, oligonucleotides or oligonucleotide analogs are designed to bind to RNA secondary structures which are of significance to the expression of the gene coding for said RNA. In accordance with a preferred embodiment, methods of treatment of human immunodeficiency virus are similarly disclosed wherein the oligonucleotides or oligonucleotide analogs are targeted at the TAR, CAR or gag-pol elements of HIV.
摘要:
The present invention relates to methods and compsitions for the treatment and diagnosis of cardivascular disease, including, but not limited to, atherosclerosis, ischemia/reperfusion, hypertension, restenosis, and arterial inflammation. Specifically, the present invention identifies and describes genes which are differentially expressed in cardiovascular disease states, relative to their expression in normal, or non-cardiovascular disease states, and/or in response to manipulations relevant to cardiovascular disease. Further, the present invention identifies and describes genes via the ability of their gene products to interact with gene products involved in cardiovascular disease. Still further, the present invention provides methods for the identification and therapeutic use of compounds as treatments of cardiovascular disease. Moreover, the present invention provides methods for the diagnostic monitoring of patients undergoing clinical evaluation for the treatment of cardiovascular disease, and for monitoring the efficacy of compounds in clinical trials. Additionally, the present invention describes methods for the diagnostic evaluation and prognosis of various cardiovascular diseases, and for the identification of subjects exhibiting a predisposition to such conditions.
摘要:
A strategy for suppressing expression of one allele of an endogenous gene is provided comprising providing suppression effectors such as antigens nucleic acids able to bind to polymorphisms within or adjacent to a gene such that one allele of a gene is exclusively or preferentially suppressed and if required a replacement gene can be introduced. The invention has the advantage that the same suppression strategy when directed to polymorphisms could be used to suppress, in principle, many mutations in a gene. This is particularly relevant when large numbers of mutations within a single gene cause disease pathology.

摘要:
Novel peptide nucleic acids and novel linked peptide nucleic acids, form triple stranded structures with nucleic acids. The peptide nucleic acids include ligands such as naturally occurring nucleobases attached to a peptide backbone through a suitable linker. Other nucleobases including C-pyrimidines and iso-pyrimidines can be used as the ligands in Hoogsteen strands to increase binding affinity. Two peptide nucleic acid strands are joined together with a linker to form a bis-peptide nucleic acid. The individual strands of the peptide nucleic acids in the bis compounds can be oriented either parallel or antiparallel to each other.
摘要:
A mutagenic, triplex-forming oligonucleotide and methods for use thereof wherein the oligonucleotide is chemically modified to incorporate a mutagen and forms a triple-stranded nucleic acid molecule with a specific DNA segment of a target DNA molecule. Upon formation of the triplex, the mutagen is brought into proximity with the target molecule and causes a mutation at a specific site therein. The mutation activates, inactivates or alters the activity and function of the target molecule.
