Patents by Inventor Johannes Ekkehart Zuber

Johannes Ekkehart Zuber has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20150283101
    Abstract: Provided is a mosaic mouse model for use in determining the potency of an shRNA in vivo for reducing survival of cancer cells of chemotherapy-resistant leukemia. The syngeneic mouse recipient is transplanted with tet-on competent leukemia cells carrying a bicistronic nucleic acid construct comprising a promoter operably linked to a fusion gene associated with chemotherapy-resistant leukemia, and a sequence encoding a reverse tet-transactivator protein, such that both coding sequences are co-expressed from the promoter. Also provided are methods of treating soft tissue cancers.

  • Publication number: 20150057164
    Abstract: 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.
