    • A linear double-stranded RNA molecule, which comprises two or more consecutively or convergently linked short interfering RNAs (siRNAs) each reducing the expression of one of different target genes, and a recombinant expression vector comprising double-stranded DNA sequence expressing the linear double-stranded RNA molecule are provided. The linear double-stranded RNA molecule or the recombinant expression vector is useful for a method of reducing expression of target genes in a cell, the method comprising introducing the linear double-stranded RNA molecule or the recombinant expression vector into the cell, whereby the encoded siRNAs target different genes and reduce expression of the target genes. It was also proved that effective gene silencing activity can be induced when each siRNA unit within the linear double-stranded RNA molecule has 18 to 24 nucleotides and, additionally, the gene silencing activity is not affected by inverted orientation of an siRNA.
    • 线性双链RNA分子,其包含两个或更多个连续或趋向连接的短干扰RNA(siRNA),每个短干扰RNA减少一个不同靶基因的表达;以及重组表达载体,其包含表达线性双链RNA的双链DNA序列, 提供了双链RNA分子。 线性双链RNA分子或重组表达载体可用于减少细胞中靶基因表达的方法,该方法包括将线性双链RNA分子或重组表达载体引入细胞,由此编码 siRNA靶向不同的基因并减少靶基因的表达。 还证明当线性双链RNA分子内的每个siRNA单元具有18至24个核苷酸时,可以诱导有效的基因沉默活性,此外,基因沉默活性不受siRNA反向取向的影响。

    • The present invention provides a novel angiogenesis inhibitor, LK68 whose amino acid sequence is identical with the human apolipoprotein (a) kringle domains IV36, IV37 and V38, a cDNA sequence encoding the LK68, a recombinant expression vector comprising the cDNA, a recombinant microorganism transformed with the recombinant expression vector and a novel use of the LK68 as an anticancer agent and a method for treating angiogenesis-mediated disease. LK68, LK6, LK7 and LK8 exhibit inhibitory activities on the cultured endothelial cell proliferation as well as on the endothelial cell migration. LK68 and its single kringles also inhibit the normal development of capillaries in the chick embryo chorioallantoic membrane (CAM). It was also showed that systemic administration of LK68 causes the inhibition of primary tumor growth, which is correlated with a suppression of tumor-induced angiogenesis. Accordingly, LK68 protein, its single kringles or their functional equivalents may be applied for the development of a potent anti-cancer agent, which is highly effective for angiogenesis-mediated diseases covering cancer, rheumatoid arthritis, psoriasis, ocular angiogenic disease, etc.
    • 本发明提供了一种新型的血管生成抑制剂LK68,其氨基酸序列与人载脂蛋白(a)三环结构域IV36,IV37和V38相同,编码LK68的cDNA序列,包含cDNA的重组表达载体,转化的重组微生物 用重组表达载体和LK68作为抗癌剂的新用途和治疗血管生成介导的疾病的方法。 LK68,LK6,LK7和LK8表现出对培养的内皮细胞增殖以及内皮细胞迁移的抑制活性。 LK68及其单克隆也抑制鸡胚绒毛尿囊膜(CAM)毛细血管的正常发育。 还表明,LK68的全身给药导致原发性肿瘤生长的抑制,其与抑制肿瘤诱导的血管发生相关。 因此,LK68蛋白,其单克隆或其功能等同物可用于开发有效的抗癌剂,其对于涵盖癌症,类风湿性关节炎,牛皮癣,眼血管生成疾病等的血管生成介导的疾病是非常有效的。
