Abstract: The invention describes methods for inhibiting angiogenesis in a tissue by administering an antagonist that specifically binds to a proteolyzed or denatured laminin with substantially greater affinity than to the native form of laminin. Methods utilizing such antagonists for therapeutic treatment of tumor growth, tumor metastasis or of restenosis also are described, as are methods to use such antagonists as diagnostic markers of angiogenesis in normal or diseased tissues both in vivo and ex vivo.

Abstract: The present invention relates to the inhibition of melanogenesis with para-aminobenzoic acid (PABA) and its use in treating melanotic cancer.

Abstract: The present invention describes methods for inhibition angiogenesis in tissues using organic peptidomimetic &agr;v&bgr;3 antagonists, and particularly for inhibiting angiogenesis in inflamed tissues and in tumor tissues and metastases using therapeutic compositions containing &agr;v&bgr;3 antagonists. The antagonists are organic compounds having a basic group and an acidic group spaced from one another by a distance in the range of about 10 Angstroms to about 100 Angstroms, as described in detail herein.

Abstract: The present invention describes methods for inhibition of angiogenesis in tissues using vitronectin &agr;v&bgr;3 antagonists, and particularly for inhibiting angiogenesis in inflamed tissues and in tumor tissues and metastases using therapeutic compositions containing &agr;v&bgr;3 antagonists.

Abstract: The present invention provides methods and compositions for inhibiting angiogenesis, tumor growth and treating disease states using a peptide that contains a specific amino acid sequence of matrix metalloproteinase 2 (MMP-2). In one embodiment, the invention provides a peptide, which comprises the amino acid sequence Ile-Phe-Ala-Gly-Asp-Lys-Phe-Trp-Arg, preferably flanked by cysteine residues at the amino and carboxy termini. Additionally, the invention provides compositions for inhibiting angiogenesis or tumor growth or for treating disease states comprising organic and non-peptidic mimetics based on the above amino acid sequence as well as optimized sequences flanking the region of MMP-2 within which the sequence lies. Also provided are methods for detecting angiogenesis, tumorous tissue, metastases, and tumor invasion into a tissue by contacting a composition of the invention with a tissue and methods for screening compositions of the invention.
