    摘要: This invention provides a genetically tractable in situ non-human animal model for hepatocellular carcinoma. The model is useful, inter alia, in understanding the molecular mechanisms of liver cancer, in understanding the genetic alterations (e.g., in oncogenes and tumor suppressor genes) that lead to chemoresistance or poor prognosis, and in identifying and evaluating new therapies against hepatocellular carcinomas. The liver cancer model of this invention is made by altering hepatocytes to increase oncogene expression, to reduce tumor suppressor gene expression or both, preferably by inducible, reversible, and/or tissue specific expression of double-stranded RNA molecules that interfere with the expression of a target gene, and by transplanting the resulting hepatocytes into a recipient non-human animal. The invention further provides a method to treat cancer involving cooperative interactions between a tumor cell senescence program and the innate immune system.

    摘要: Provided is a single construct combining a sequence encoding an RNAi molecule, a sequence encoding a reporter, and a target sequence specific for the RNAi molecule. The construct can be used to determine the potency of the encoded RNAi molecule in a direct and unbiased way. These results can be used to inform the design of potent RNAi molecules of various types and can be extended to several other applications, including: (1) generation of tiled libraries comprising every possible RNAi molecule-encoding sequence for a given gene target; (2) large-scale parallel validation of RNAi molecules targeting many genes to generate validated RNAi molecule-encoding libraries; (3) experimental comparison of design algorithms and strategies; and (4) investigation of RNAi biology in target site mutagenesis assays by screening pools containing single nucleotide changes in target sites and/or in the RNAi molecule to identify the most relevant sequence characteristics of potent RNAi-target site predictions.
