Methods for producing interfering RNA molecules in mammalian cells are provided. Therapeutic uses for the expressed molecules, including inhibiting expression of HIV, are also provided.
摘要:
The invention provides compositions and methods for selectively reducing the expression of a gene product from a desired target gene, as well as treating diseases caused by expression of the gene. The method involves introducing into the environment of a cell an amount of a double-stranded RNA (dsRNA) such that a sufficient portion of the dsRNA can enter the cytoplasm of the cell to cause a reduction in the expression of the target gene. The dsRNA has a first oligonucleotide sequence that is between 26 and about 30 nucleotides in length and a second oligonucleotide sequence that anneals to the first sequence under biological conditions. In addition, a region of one of the sequences of the dsRNA having a sequence length of from about 19 to about 23 nucleotides is complementary to a nucleotide sequence of the RNA produced from the target gene.

摘要:
The present invention relates to novel short interfering RNA (siRNA) molecules that are multi-targeted. More specifically, the present invention relates to siRNA molecules that target two or more sequences. In one embodiment, multi-targeting siRNA molecules are designed to incorporate features of siRNA molecules and features of micro-RNA (miRNA) molecules. In another embodiment, multi-targeting siRNA molecules are designed so that each strand is directed to separate targets.
摘要:
Double-stranded and single-stranded RNA molecules, and their use in methods for inducing interferon are provided. The interferon induction provides anti-viral and other medically useful effects, such as anti-cancer effects. Also provided are methods for reducing or inhibiting interferon induction exhibited by such molecules, particularly siRNA and shRNA molecules produced in vitro.
摘要:
A method for identifying sites on a target RNA which are accessible to pairing by antisense DNA, ribozymes or DNAzymes. Native or in vitro-synthesized target RNA is incubated with defined ODNs and RNase H, or with a random or semi-random ODN library and RNase H, or with defined ribozymes or DNAzymes, or with a semi-random ribozyme or DNAzyme library, in a cell extract containing endogenous RNA-binding proteins, or in a medium which mimics a cell extract due to presence of one or more RNA-binding proteins. Any antisense ODN, ribozyme or DNAzyme which is complementary to an accessisble site in the target RNA hybridizes to that site and the RNA is cleaved at that site. Reverse transcription can be used to generate a first strand DNA from the RNA cleavage product, and terminal deoxynucleotidyl transferase-dependent polymerase chain reaction (TDPCR) can be used to identify sites on target RNA to which antisense ODNs, ribozymes or DNAzymes have bound and cleavage has occurred.
