Mimetic peptides having anti-angiogenic and anti-tumorigenic properties and methods of their use for treating cancer, ocular diseases, such as age-related macular degeneration, and other-angiogenesis-dependent diseases are disclosed. More particularly, an isolated peptide comprising the amino acid sequence LRRFSTAPFAFIDINDVINF, which exhibits anti-angiogenic activity in endothelial cell proliferation, migration, adhesion, and tube formation assays, anti-migratory activity in human breast cancer cells in vitro, anti-angiogenic and anti-tumorigenic activity in vivo in breast cancer xenograft models, and age-related macular degeneration models is disclosed. The isolate peptide also exhibits anti-lymphangiogenic and directly anti-tumorigenic properties.
本发明公开了具有抗血管生成和抗肿瘤特性的模拟肽及其用于治疗癌症、眼部疾病(如老年性黄斑变性)和其他依赖血管生成的疾病的方法。更具体地说,公开了一种由
氨基酸序列 LRRFSTAPFAFIDINDVINF 组成的分离肽,它在内皮细胞增殖、迁移、粘附和管形成试验中表现出抗血管生成活性,在体外人乳腺癌细胞中表现出抗迁移活性,在体内乳腺癌异种移植模型和老年性黄斑变性模型中表现出抗血管生成和抗肿瘤活性。分离肽还具有抗淋巴管生成和直接抗肿瘤的特性。
