A New Target for Angiogenesis and Anti-angiogenesis Therapy

U.S. Provisional Application No. 60/425,018 filed 07 Nov 2002 (DHHS Reference No. E-294-2002/0-US-01).

Proadrenomedullin N-terminal 20 peptide (PAMP) is a 20 amino-acid molecule originating from the post-translational processing of pre-proadrenomedullin. PAMP has heretofore been known as a potent hypotensive and vasodilatory agent. PAMP and adrenomedullin (AM) are the two known bioactive products generated from cleavage of pre-proadrenomedullin. PAMP and AM are known to have vasodilatory and hypotensive activities. AM is also known to have angiogenic activity, whereas no such activity has previously been attributed to PAMP.

The inventors have discovered that, in addition to its hypotensive and vasodilatory effects, PAMP functions as a potent angiogenic factor. When compared to other well-known angiogenic factors such as vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF), PAMP is roughly one million times more potent on a molar basis.

In one aspect, the invention relates to the use of PAMP inhibitors to inhibit angiogenesis in vivo. These methods would be useful, for example, in inhibiting the growth of tumors and in treating other diseases characterized by excessive angiogenesis including psoriasis, diabetic retinopathy, and chronic wounds. In a second aspect, the invention relates to the use of PAMP or PAMP derivatives to promote angiogenesis, for example, in subjects with coronary artery disease or cerebral ischemia.
