    摘要： The invention provides methods and systems for controlling the expression and, in general, the cellular activity of preselected polynucleic acid molecules. The invention also provides methods and systems for genetically modifying cells and multi-cellular organisms to impart resistance to viruses. The invention further provides methods and systems for genetically modifying cells and multi-cellular organisms so that they diagnostically report viral infection. One aspect of the invention involves rendering target polynucleic nucleic acid molecules as functional templates for at least one template-directed polynucleic acid polymerase so that utilization of the polynucleic acid molecule as a template by the polymerase modulates the activity of the targeted polynucleic acid molecule. Other aspects of the invention of the invention involve rendering selected polynucleic nucleic acid molecules as targets for RNA silencing, whether or not the silencing is polymerase-mediated.

    摘要： This invention provides a method for assaying activities of signal transduction that enables identification of a ligand with a single assay method, thereby simplifying and accelerating the assay method for identifying a ligand of a GPCR with unknown functions. In this method, RNA encoding a GPCR and RNA encoding a chimeric Gqnull subunit constituted by a portion of a G11 or Gq subunit and a portion of a G14, G15, or G16 subunit are transfected together to an oocyte removed from a Xenopus and selected by a conventional technique. After transfection of the RNAs, a ligand candidate substance is added to the oocyte that was cultured for a given period of time, and the activity is then assayed.

    摘要： Abstract of DisclosureThe present invention is directed generally to reduction or inactivation of gene function or gene expression in cells in vitro and in multiorganisms. The invention encompasses methods for mutating cells using a combination of mutagens, particularly wherein at least one mutagen is an insertional mutagen, to achieve homozygous gene mutation or mutation of multiple genes required cumulatively to achieve a phenotype to create knock-outs, knock-downs, and other modifications in the same cell. The invention is also directed to cells (and libraries thereof) and organisms created by the methods of the invention, including those in which at least one of the genes created by insertional mutagenesis is tagged by means of the insertion sequences thereby allowing identification of the mutated gene(s). The invention is also directed to libraries of mutated cells and their uses. The invention is also directed to methods of identifying mutations with methods of the invention, in cells (and libraries thereof) and organisms, by means of the insertional tag.
