Treating cardiovascular or renal diseases
This document provides methods and materials for treating cardiovascular and/or renal diseases. For example, AAV9 vectors designed to express natriuretic polypeptides, nucleic acid molecules encoding natriuretic polypeptides, methods for making AAV9 vectors, and methods for using such vectors or molecules to treat cardiovascular and/or renal diseases are provided.
1. A method for improving cardiac function in a mammal with polycystic kidney disease, wherein said method comprises administering an AAV8 vector to said mammal with polycystic kidney disease,
wherein said AAV8 vector comprises a nucleic acid sequence encoding a natriuretic polypeptide, and
wherein cardiac function is improved at least two months following said administration when said AAV8 vector is administered to said mammal with polycystic kidney disease.
2. The method of claim 1 , wherein said mammal is a human.
3. The method of claim 1 , wherein said natriuretic polypeptide is a human BNP polypeptide.
4. The method of claim 1 , wherein said natriuretic polypeptide is a CDNP polypeptide.
5. The method of claim 1 , wherein said natriuretic polypeptide is a B-CDNP polypeptide.
6. The method of claim 1 , wherein said natriuretic polypeptide is a C-CDNP polypeptide.
