Expression of exogenous polynucleotide sequences cardiac muscle of a mammal
First Claim
1. A method of delivering a desired physiologically active protein, polypeptide or peptide to a mammal, comprising:
- injecting into the cardiac muscle of the mammal a non-infectious, non-integrating DNA sequence encoding said protein, polypeptide or peptide operably linked to a promoter,wherein said DNA sequence is free from association with transfection-facilitating proteins, viral particles, liposomal formulations,, charged lipids and calcium phosphate precipitating agents, whereby said DNA sequence is expressed.

Abstract
The present invention provides a method for delivering a pharmaceutical polypeptide to the interior of a cardiac cell of a vertebrate in vivo, comprising the step of introducing a preparation comprising a pharmaceutically acceptable injectable carrier and naked polynucleotide operatively coding for the polypeptide into the interstitial space of the heart, whereby the naked polynucleotide is taken up into the interior of the cell and has a pharmacological effect on the vertebrate. In a preferred embodiment wherein the polynucleotide encodes polypeptide immunologically foreign to the vertebrate, the delivery method preferably comprises delivering an immunosuppressive agent to the vertebrate to limit immune responses directed to the polypeptide.

23. A method of delivering firefly luceriferase to the interior of a cardiac muscle cell of a rat, comprising injecting into heart of said rat a DNA plasmid constructed of sequence encoding said firefly luceriferase operably linked to a RSV promoter in an amount sufficient for said firefly luceriferase to be detected inside said cardiac muscle cell, wherein said plasmid is free from association with transfection-facilitating viral capsid proteins, liposomes, cationic lipids, and calcium phosphate precipitating agents.
