  • Patent number: 9481884
    Abstract: The present invention provides a method of enabling the use of long dsRNA for gene silencing in mammalian cells through bacteria, preferably non-pathogenic or therapeutic strains of bacteria. DNA that encodes long double-strand RNAs are transformed into bacteria and processed in the bacterial cells into a mixture of smaller RNA duplexes and then released into the cytoplasm of the target cells, resulting in modulation of gene expression in the target cells. The methods overcome the incompatibility between long strong dsRNA and mammalian cells by eliminating, or mitigating, the non-specific innate immune response. The eukaryotic cells can be mammalian cells or avian cells. The gene of interest can be a mammalian, avian, bacterial, eukaryotic, or viral gene.

  • Patent number: 9481885
    Abstract: The present invention provides materials and methods related to the discovery that tumor secreted miR-21 and miR-29a can function by binding as ligands to receptors of the Tolllike receptor family, murine TLR7 and human TLR8, in immune cells, triggering a TLR-mediated prometastatic inflammatory response, which leads to tumor growth and metastasis. Thus, by acting as paracrine agonists of TLRs, secreted miRNAs are key regulators of the tumor microenvironment. This mechanism of action of miRNAs is important in the tumor-immune system communication, in tumor growth and spread, and in cancer treatment.

  • Patent number: 9481898
    Abstract: The disclosure provides a process that converts CO2 to higher alcohols (e.g. isobutanol) using electricity as the energy source. This process stores electricity (e.g. from solar energy, nuclear energy, and the like) in liquid fuels that can be used as high octane number gasoline substitutes. Instead of deriving reducing power from photosynthesis, this process derives reducing power from electrically generated mediators, either H2 or formate. H2 can be derived from electrolysis of water. Formate can be generated by electrochemical reduction of CO2. After delivering the reducing power in the cell, formate becomes CO2 and recycles back. Therefore, the biological CO2 fixation process can occur in the dark.

  • Patent number: 9481907
    Abstract: A two-step multiplex amplification reaction includes a first step which truncates the standard initial multiplex amplification round to “boost” the sample copy number by only a 100-1000 fold increase in the target. Following the first step the product is divided into optimized secondary single amplification reactions, each containing one of the primer sets that were used previously in the first or multiplexed booster step. The booster step can occur using an aqueous target nucleic acid or using a solid phase archived nucleic acid. In particular, nucleic acid sequences that uniquely identify E. Coli were identified using the multiplex amplification method.

  • Patent number: 9481908
    Abstract: The invention herein disclosed provides for devices and methods that can detect and control an individual polymer in a mixture is acted upon by another compound, for example, an enzyme, in a nanopore in the absence of requiring a terminating nucleotide. The devices and methods are also used to determine rapidly (˜>50 Hz) the nucleotide base sequence of a polynucleotide under feedback control or using signals generated by the interactions between the polynucleotide and the nanopore. The invention is of particular use in the fields of drug discovery, molecular biology, structural biology, cell biology, molecular switches, molecular circuits, and molecular computational devices, and the manufacture thereof.

  • Patent number: 9481909
    Abstract: The invention relates to a method for simultaneous quantification of human nuclear DNA and human male DNA in a biological sample while also detecting the presence of PCR inhibitors in a single reaction. The multiplex quantification method also provides a ratio of human nuclear and male DNA present in a biological sample. Such sample characterization is useful for achieving efficient and accurate results in downstream molecular techniques such as genotyping.

  • Patent number: 9481910
    Abstract: The present invention provides methods and compositions for the detection of novel BRAF splice variants that mediate resistance to BRAF and/or pan-RAF inhibitors. In particular, the invention provides PCR primer(s) to be used in the disclosed methods of detection. In some embodiments, the compositions and methods of the present invention are used to predict resistance to BRAF and/or pan-RAF inhibitors in a subject suffering from or suspected of having cancer and further provides alternative treatment strategy(ies) for a subject predicted to be resistant to BRAF and/or pan-RAF inhibitors. In a further embodiment, methods and composition for the identification of novel agents useful to overcome resistance to BRAF and/or pan-RAF inhibitors are disclosed. The present invention also provides isolated polynucleotide sequences of novel 5? BRAF splice variant(s) and proteins produced from such polynucleotide sequences as well as cell line(s) that endogenously or exogenously express the splice variant(s).

  • Patent number: 9481911
    Abstract: [Problem] The present invention aims to elucidate a polynucleotide as a novel responsible gene for cancer and aims to thus provide a method for detecting the polynucleotide and a polypeptide encoded by the polynucleotide and a detection kit, a probe set, and a primer set for the detection. The present invention also aims to provide a pharmaceutical composition for treating cancer. [Means for Solution] The method detects a fusion gene composed of a portion of an FGFR3 gene and a portion of a TACC3 gene or a fusion protein encoded by the fusion gene. The primer set, the probe set, or the detection kit comprises a sense primer and a probe set designed from the portion encoding FGFR3 and an antisense primer and a probe set designed from the portion encoding TACC3. Since an inhibitor of the polypeptide exhibits antitumor effect, a pharmaceutical composition for treating cancer which is positive for either the fusion gene or the polypeptide is provided.

  • Patent number: 9481914
    Abstract: The present invention relates to methods for the diagnosis of bacterial vaginosis based on an analysis of a patient sample. For example, patient test samples are analyzed for the presence or absence of one or more lactobacilli and two or more pathogenic organisms. The presence or absence of one or more lactobacilli and two or more pathogenic organisms may be detected using PCR analysis of nucleic acid segments corresponding to each target organism. The quantity of the target organisms can then be used to determine a score which is indicative of a diagnosis of bacterial vaginosis.
