  • Chitosan-based non-viral methods for transfecting gut cells in vivo
    Patent number: 9404088
    Abstract: The present invention provides chitosan-based nanoparticles that can protect nucleic acids and deliver the same into gut mucosal cells. Compositions and methods for the expression of therapeutic nucleic acids in cells of the gut mucosa are provided. Compositions and methods for delivering therapeutic proteins systemically from cells of the gut mucosa are also provided.
    Type: Grant

  • CANCER TREATMENT BY METABOLIC MODULATIONS
    Publication number: 20090041740
    Abstract: The invention provides compositions and methods for inhibiting the growth or proliferation of hyperproliferative cells or inducing regression of hyperproliferative cells. More specifically, the invention provides compositions and methods for stimulating glycogen accumulation in target cells (e.g., hyperproliferative cells) in order to increase glycogen to a level that is toxic to the target cell.
