Abstract

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.

Claims Analysis

Total Claims: 25
Claim 1
Independent Claim 68 words
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.
Claim 2
Independent Claim 68 words
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.
Claim 3
Dependent Claim 17 words
The method of claim 1, wherein said DNA sequence is further free from any transfection facilitating material.
Claim 4
Dependent Claim 17 words
The method of claim 1 wherein said protein, polypeptide or peptide is immunologically native to said host.
Claim 5
Dependent Claim 17 words
The method of claim 1 wherein said protein, polypeptide or peptide is immunologically foreign to said host.
Claim 6
Dependent Claim 28 words
The method of claim 4 wherein said method additionally comprises administering an immunosuppressive agent to said host to limit immune responses directed to said protein, polypeptide or peptide.
Claim 7
Dependent Claim 18 words
The method of claim 5 wherein said host is immunosuppressed prior to said injection of said DNA sequence.
Claim 8
Dependent Claim 18 words
The method of claim 5 wherein said host is immunosuppressed simultaneous with said injection of said DNA sequence.
Claim 9
Dependent Claim 12 words
The method of claim 5 wherein said immunosuppressive agent is administered intravenously.
Claim 10
Dependent Claim 14 words
The method of claim 5 wherein said immunosuppressive agent is administered to the heart.
Claim 11
Dependent Claim 13 words
The method of claim 1 wherein said promoter is a muscle specific promoter.
Claim 12
Dependent Claim 13 words
The method of claim 1 wherein said promoter is a cardiac specific promoter.
Claim 13
Dependent Claim 23 words
The method of claim 1 wherein said DNA sequence contains a sequence operatively coding for the secretion of said protein, polypeptide or peptide.
Claim 14
Dependent Claim 16 words
The method of claim 1 wherein the production of said protein, polypeptide or peptide is transitory.
Claim 15
Dependent Claim 14 words
The method of claim 1 wherein said protein, polypeptide or peptide is an enzyme.
Claim 16
Dependent Claim 14 words
The method of claim 1 wherein said protein, polypeptide or peptide is a hormone.
Claim 17
Dependent Claim 15 words
The method of claim 1 wherein said protein, polypeptide or peptide is a growth factor.
Claim 18
Dependent Claim 15 words
The method of claim 1 wherein said protein, polypeptide or peptide is a regulatory sequence.
Claim 19
Dependent Claim 14 words
The method of claim 1 wherein said protein, polypeptide or peptide is an immunoregulator.
Claim 20
Dependent Claim 12 words
The method of claim 1 wherein said DNA sequence is injected myocardially.
Claim 21
Dependent Claim 18 words
The method of claim 1 wherein said DNA sequence is injected into the ventricular wall of the heart.
Claim 22
Dependent Claim 17 words
The method of claim 1 wherein said DNA sequence is injected in combination with a chelating agent.
Claim 23
Dependent Claim 11 words
The method of claim 21 wherein said chelating agent is EDTA.
Claim 24
Independent Claim 76 words
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.
Claim 25
Independent Claim 76 words
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.
