    • The present invention features methods and compositions for preventing, reducing, or treating hypoxia and,pathological disorders involving abnormal angiogenesis. Thus, the present invention is useful for treating, reducing, or preventing ischernic conditions (characterized by a reduced blood flow or reduced angiogenesis, e.g., a myocardial infarct) and hypervascular conditions (characterized by excessive angiogenesis, e.g., cancer). Where an increase in angiogenesis is desired, the mammal being treated for an ischernic condition is provided with Related Transcriptional Enhancer Factor-1 (RTEF-1; as a recombinant polypeptide or as an expression vector) sufficient to increase expression of VEGF, FGFR, or COX-2. This results in a concomitant increase in angiogenesis. Conversely, a mammal being treated for a hypervascular condition is administered a composition that reduces the levels of RTEF-1, thereby reducing the expression of VEGF, FGFR, or COX-2, which results in a decrease in angiogenesis. Also disclosed are screening methods that make use of RTEF-1 for the identification of novel therapeutics for the treatment, prevention, or reduction of pathological disorders involving hypoxia or abnormal angiogenesis, namely, ischernic or hypervascular conditions.
    • 本发明的特征在于用于预防,减少或治疗缺氧和涉及异常血管生成的病理学病症的方法和组合物。 因此,本发明可用于治疗,减轻或预防血液循环状况(以血流量减少或血管生成减少,例如心肌梗塞为特征)和血管过度状况(以过度血管生成如癌症为特征)。 当需要增加血管生成时,为肌肉病症治疗的哺乳动物提供足以增加VEGF,FGFR或VEGF的表达的相关转录增强因子-1(RTEF-1;作为重组多肽或表达载体) COX-2。 这导致血管生成的伴随增加。 相反地​​,正在治疗血管过多病症的哺乳动物施用降低RTEF-1水平的组合物,由此降低VEGF,FGFR或COX-2的表达,这导致血管生成的降低。 还公开了使用RTEF-1来筛选用于治疗,预防或减少涉及缺氧或异常血管生成的病理学病症(即,ischernic或hypervascular病症)的新型治疗剂的筛选方法。
