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.

Cellular regulators of infectious agents and methods of use

The invention provides substantially pure tumor suppressor nucleic acid molecules and tumor suppressor polypeptides. The invention also provides hairpin ribozymes and antibodies selective for these tumor suppressor molecules. Also provided are methods of detecting a neoplastic cell in a sample using detectable agents specific for the tumor suppressor nucleic acids and polypeptides.

Tumor suppressor molecules and methods of use

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.

Gene functional analysis and discovery using randomized or target-specific ribozyme gene vector libraries

This invention provides ribozymes useful to treat or prevent Hepatitis C Virus (&ldquo;HCV&rdquo;) infection or disease in an organism or subject, as well as methods of treating an HCV infection or disease. Reagents such as vectors, host cells, DNA molecules coding for these ribozymes usefull in methods of treatment and prevention of HCV infection or disease are also provided.

Hepatitis C Virus ribozymes

This invention provides ribozymes useful to treat or prevent Hepatitis C Virus ('HCV') infection or disease in an organism or subject, as well as methods of treating an HCV infection or disease. Reagents such as vectors, host cells, DNA molecules coding for these ribozymes useful in methods of treatment and prevention of HCV infection or disease are also provided.
