摘要:
Methods of inhibiting HIV infection by blocking HIV co-receptor RNA expression are provided. Ribozymes which cleave HIV co-receptor RNA and inhibit HIV infection of cells are also provided. Co-receptor targets include fusin and CKR5.
摘要:
GUC and GUA ribozymes which cleave HIV RNA are provided. The ribozymes cleave HIV RNA in vitro and in vivo. When the ribozymes are expressed in cells, they inhibit HIV replication in the cells.
摘要:
An inducible siRNA expression polynucleotide and methods for its use are provided. The expression polynucleotide comprises a bicistronic expression cassette that encodes a repressor and a detectable marker, wherein the repressor controls expression of siRNA expression in the absence of an inducer.
摘要:
The present invention provides a hairpin ribozyme library having a randomized recognition sequence, packaged in a vector and operably linked to a promoter suitable for high level expression in a wide variety of cells. The invention comprises using the library in a variety of selection protocols for identifying, isolating and characterizing known or unknown target RNAs, to reveal the phenotypic effects of such cleavage, and to identify the gene products that produce those phenotypic effects.
摘要:
The present invention relates generally to the synthesis of novel quinolinium salts and derivative compounds. Such salts and compounds are useful for inhibiting the growth of cancer cells.
摘要:
A method of identifying a compound that modulates the activity of a cellular regulator is provided. The method consists of contacting a sample containing a cellular regulator and a nucleic acid element acted on by the cellular regulator with a test compound under conditions that allow replication or expression of the nucleic acid element or a gene or MRNA operatively linked to the nucleic acid element or gene, and an increase or decrease in the amount of replication or expression in the presence of the test compound compared to the absence of the test compound indicates that the compound has cellular regulator modulatory activity. A method of treating a HCV infection is also provided.
摘要:
The present invention provides methods for identifying agents useful for inhibiting cancer cells by binding to various nuclear receptor proteins, or to the genes or RNA encoding such proteins.
摘要:
The present invention provides novel assays for assessing cancerous cell growth. The invention is useful for the identification and validation of oncogenes and tumor suppressors, as well as for the identification and validation of therapeutic compounds for the treatment of cancer.
摘要:
