    • Methods for determining angiogenesis associated with a disease in a subject include the steps of, in a suitable test sample, determining expression levels of at least one gene selected from junB and ICAM 1. A statistically significant decrease in, or low level of, expression of one or both of the genes indicates the presence of angiogenesis associated with the disease in the subject. Preferably, the test sample includes endothelial cells. The method may further include determining the expression of THBSl and/or IGFBP3. Methods of determining angiogenesis in a subject may also include determining the level of acetylated histone H3 in the promote region of the IGFBP3 gene in a test sample. Pharmaceutical compositions for use in inhibiting angiogenesis include a DNA methyltransf erase inhibitor together with a pharmaceutically acceptable carrier and are in a form suitable for metronomic dosing. They may alternatively or additionally include a component allowing targeting to endothelial cells. Methods of preventing or inhibiting angiogenesis associated with a disease in a subject involve administering a therapeutically effective amount of a DNA methyltransf erase inhibitor. Treatment regimes, microarrays and screening methods are also described.
    • 用于测定与受试者疾病相关的血管生成的方法包括以下步骤:在合适的测试样品中,确定至少一种选自junB和ICAM1的基因的表达水平。统计学上显着的降低或低水平的 基因中的一个或两个表示与受试者中的疾病相关的血管发生的存在。 优选地,测试样品包括内皮细胞。 该方法还可以包括确定THBS1和/或IGFBP3的表达。 确定受试者血管生成的方法还可以包括确定测试样品中IGFBP3基因的促进区中的乙酰化组蛋白H3的水平。 用于抑制血管发生的药物组合物包括DNA甲基转移酶抑制剂和药学上可接受的载体,并且是适合于节律剂剂量的形式。 它们可以或者另外包括允许靶向内皮细胞的成分。 预防或抑制与受试者疾病相关的血管发生的方法包括给予治疗有效量的DNA甲基转移酶抑制剂。 还描述了治疗方案,微阵列和筛选方法。
