  • Publication number: 20190048401
    Abstract: This invention provides for compositions for use in real time nucleic acid detection processes. Such real time nucleic acid detection processes are carried out with energy transfer elements attached to nucleic acid primers, nucleotides, nucleic acid probes or nucleic acid binding agents. Real time nucleic acid detection allows for the qualitative or quantitative detection or determination of single-stranded or double-stranded nucleic acids of interest in a sample. Other processes are provided by this invention including processes for removing a portion of a homopolymeric sequence, e.g., poly A sequence or tail, from an analyte or library of analytes. Compositions useful in carrying out such removal processes are also described and provided. Paneling and multiplex analyses of more than one nucleic acid analyte using one sample are also provided.

  • Publication number: 20170071950
    Abstract: The present invention identifies compounds that disrupt the interaction between anthrax proteins and LRP5/6 receptors, resulting in a reduction in anthrax toxicity. The compounds act to disrupt the intracellular transport of toxin complexes into a target cell. The present invention also provides methods for testing the effect of compounds on Wnt activity, through the use of in vitro experiments involving cells that have in at least one gene mutation involved in the Wnt pathway.

  • Patent number: 9052324
    Abstract: The present invention relates to the field of therapeutic methods to screen for compounds on the basis of their ability to influence Wnt activity. The screening process is applied to both a physical library of a series of compounds and a virtual library of compounds that affect Wnt activity. In one aspect, the virtual screening process could be carried out where a permutational library of small peptides is substituted for the small organic molecules. The inventive methods may be used to empirically test for effects on Wnt activity and may also be applied to any pair of proteins involved in protein-protein interactions.

  • Patent number: 8969339
    Abstract: The present disclosure is directed to methods of identifying a compound that binds to or interacts with a protein receptor involved in bone formation. Specifically, the disclosure is directed to methods of identifying a compound that regulates a Wnt pathway in a cell by binding to or interacting with cavities in proteins such as LRP5, LRP 6 and/or frizzled receptor and interfering with receptor binding to other proteins in a Wnt pathway. The present disclosure is further directed to methods and compositions that comprise an identified compound for treating or preventing a disease in a mammal in which Wnt pathway suppression plays a role.

  • Patent number: 8846893
    Abstract: The present invention provides an array of compositions useful for effecting and/or exhibiting changes in biological functioning and processing within cells and in biological systems containing such cells. In effect, these compositions combine chemical modifications and/or ligand additions with biological functions. The chemical modifications and/or ligand additions provide additional characteristics to the compositions without interfering substantially with their biological function. Such additional characteristics include nuclease resistance, targeting specific cells or specific cell receptors localizing to specific sites within cells and augmenting interactions between the compositions and target cells of interest as well as decreasing such interactions when desired. Also provided by the present invention are processes and kits.
