  • Patent number: 9770491
    Abstract: Described herein are methods of preventing, arresting progression of or ameliorating vision loss and other conditions associated with retinitis pigmentosa and x-linked retinitis pigmentosa in a subject. The methods include administering to a subject an effective concentration of a composition comprising a recombinant adeno-associated virus (AAV) carrying a nucleic acid sequence encoding a normal retinitis pigmentosa GTPase regulator (RPGR gene), or fragment thereof, under the control of regulatory sequences which express the product of the gene in the photoreceptor cells of the subject, and a pharmaceutically acceptable carrier.

  • Publication number: 20120157513
    Abstract: The present invention is directed to a delivery vector for transferring a small peptide coding sequence to a cell for expression of the small peptide coding sequence within the cell. The delivery vector comprises a secretory signal sequence; a sequence encoding a carrier protein operatively associated with the secretory signal sequence; a sequence encoding a cleavage site operatively associated with the sequence encoding a carrier protein; and a sequence encoding a small peptide operatively associated with the sequence encoding a cleavage site.

  • Patent number: 7838659
    Abstract: Hammerhead ribozymes that target components critical to HSV replication (ICP4, UL20, UL30, and UL54) were synthesized and shown to efficiently cleave target RNA encoding a portion of these components in in vitro assays. Several cloned cell lines stably expressing these ribozymes were established. HSV-mediated plaque formation was dramatically reduced in cells stably transfected with an anti-HSV ribozyme compared to non-transfected cells.
