Regulatory elements for controlling expression of transgenes in angiogenic tissue are provided. One embodiment provides an isolated nucleic acid having at least 80%, 85%, 90%, 95%, 97%, 99% or 100% sequence identity to SEQ ID NO:1, or a fragment thereof that causes expression of a transgene in angiogenic tissue. Vectors containing SEQ ID NO:1 and one or more transgenes are also provided. A preferred vector is an adenovirus vector. The transgene can encode a cytotoxin, pro-apoptotic polypeptide, or a therapeutic polypeptide. SEQ ID NO:1 regulates the expression of the transgene such that the transgene is only expressed in angiogenic tissue including, but not limited to arteries feeding ischemic tissues. Methods of using vectors containing SEQ ID NO:1 are also provided. |
