  • Publication number: 20020061862
    Abstract: The invention provides a pharmaceutical composition comprising as an active ingredient a pharmaceutical agent comprising a DNA sequence that codes for a protein which possesses the biological activity of inducible nitrogen monoxide synthase (iNOS) and eukaryotic regulation elements, wherein the eukaryotic regulation elements result in the expression of said DNA sequence in eukaryotic cells, and a pharmaceutically acceptable carrier. The pharmaceutical agent can be complexed to liposomes.

  • Patent number: 6103230
    Abstract: The present invention provides a method of promoting the closure of a wound in a patient. This method involves transferring exogenous iNOS to the region of the wound whereby a product of iNOS is produced in the region of the wound to promote the closure of the wound. The present invention also provides a method of transplanting a graft into a patient, which method involves transferring a vector comprising an iNOS expression cassette to cells associated with the graft and surgically incorporating the graft tissue into the patient. Upon expression of iNOS within the patient, a product of iNOS is produced in the region of the graft to attenuate vasculopathy in the region of the graft.
