Abstract

This document relates to adenovirus vectors and methods and materials related to using adenovirus vectors. For example, viruses, nucleic acid molecules encoding viruses, cell lines containing viral vectors, and methods for using viruses to deliver nucleic acid to cells in vitro or in vivo are provided. Methods and materials for using adenovirus vectors to induce immune responses and to treat cancer also are provided.

Claims

1-6. -6. (canceled)

7. A method for delivering a therapeutic polypeptide to a mammal, wherein said method comprises administering a single cycle replicating adenovirus to said mammal under conditions wherein said single cycle replicating adenovirus infects a cell of said mammal and replicates within said cell, wherein said cell does not produce new infectious virions following infection with said single cycle replicating adenovirus, wherein said single cycle replicating adenovirus comprises an adenovirus polypeptide selected from the group consisting of a fiber protein, a V protein, hexon, penton-base, and pIII, and wherein said single cycle replicating adenovirus lacks at least a portion of a nucleic acid sequence that encodes said adenovirus polypeptide, wherein when said single cycle replicating adenovirus lacks at least a portion of a nucleic acid sequence that encodes said fiber protein, said single cycle replicating adenovirus comprises a fiber protein having wild-type specificity, wherein said single cycle replicating adenovirus comprises a nucleic acid sequence encoding said therapeutic polypeptide.

8. The method of claim 7, wherein said mammal is a human.

9. The method of claim 7, wherein said therapeutic polypeptide is a thymidine kinase, a fusogenic glycoprotein, a tumor suppressor p53, a heat shock protein polypeptide.

10. The method of claim 7, wherein said cell is a tumor cell, a hematopoietic cell, a liver cell, or a gastrointestinal cell.

11. The method of claim 7, wherein said adenovirus polypeptide is a fiber protein, a V protein, hexon, penton-base, or pIII.
