    • The invention is directed to novel combinations of liver specific enhancers and promoter elements for achieving persistent transgene expression in the liver. The liver specific enhancer elements may be derived from either the human serum albumin, prothrombin, alpha -1microglobulin or aldolase genes in single copies or in multimerized form linked to elements derived from the cytomegalovirus intermediate early (CMV), alpha -1-antitrypsin or albumin promoters. In a preferred embodiment of the invention, an adenoviral vector comprising a liver specific enhancer/promoter combination operably linked to a transgene is administered to recipient cells. In other embodiments of the invention, adeno-associated viral vectors, retroviral vectors, lentiviral vectors or a plasmid comprising the liver specific enhancer/promoter combination linked to a transgene is administered to recipient cells. Also within the scope of the invention are promoter elements derived from the human prothrombin gene and the beta -fibrinogen gene.
    • 本发明涉及用于实现肝脏中持续转基因表达的肝特异性增强子和启动子元件的新型组合。 肝脏特异性增强子元件可以衍生自与来自巨细胞病毒中间体早期(CMV),α-1-抗胰蛋白酶或白蛋白的元件连接的单拷贝或多聚体形式的人血清白蛋白,凝血酶原,α-1微球蛋白或醛缩酶基因 促销员。 在本发明的优选实施方案中,向受体细胞施用包含可操作地连接到转基因的肝特异性增强子/启动子组合的腺病毒载体。 在本发明的其它实施方案中,将腺相关病毒载体,逆转录病毒载体,慢病毒载体或包含与转基因连接的肝特异性增强子/启动子组合的质粒施用于受体细胞。 也在本发明范围内的是源自人凝血酶原基因和β-纤维蛋白原基因的启动子元件。

    • The present invention provides methods and materials for the production of helper-dependent adenovirus, such as PAV, at high titers. In one embodiment, the invention comprises methods for producing high titers of helper-dependent adenovirus comprising co-transfecting a cell permissive for production of adenovirus with: a) a helper-dependent adenoviral vector comprising inverted terminal repeats (ITRs) and packaging sequence derived from a first adenoviral serotype, and a transgene of interest flanked by said ITRs; and b) a chimeric, packaging-deficient helper adenovirus which contains adenoviral genes derived from the first adenoviral serotype, packaging sequence derived from a second adenoviral serotype, and ITRs derived from either the first or second adenoviral serotypes; and collecting virions produced thereby.
    • 本发明提供了用于以高滴度生产辅助性依赖性腺病毒如PAV的方法和材料。 在一个实施方案中,本发明包括用于产生高滴度的辅助性依赖性腺病毒的方法,包括共转染允许产生腺病毒的细胞的细胞:a)包含反向末端重复序列(ITR)的辅助依赖性腺病毒载体和源自 第一种腺病毒血清型,以及所述ITR侧翼的转基因; 和b)嵌合的包装缺陷型辅助性腺病毒,其包含衍生自第一腺病毒血清型的腺病毒基因,源自第二种腺病毒血清型的包装序列和源自第一或第二种腺病毒血清型的ITR; 并收集由此产生的病毒粒子。
