摘要： A method for producing recombinant adeno-associated virus in the absence of contaminating helper virus or wild-type virus involves culturing a mammalian host cell containing an rAd/AAV hybrid virus, an AAV rep sequence and an AAV cap sequence under the control of regulatory sequences directing expression thereof. The rAd/AAV hybrid virus contains a rAAV construct to be packaged into an AAV virion in a backbone containing the adenoviral sequences necessary to express E1a and E1b gene products and to permit replication of the hybrid virus. The method of the invention permits replication of the hybrid virus and production of rAAV virion in this host cell in the absence of a helper virus and obviates a subsequent purification step to purify rAAV from contaminating virus.

摘要： Canavan disease, an autosomal recessive leukodystrophy, is caused by deficiency of aspartoacylase and accumulation of N-acetylaspartic acid in brain. Human aspartoacylase (ASP) cDNA spanning 1,435 bp has been cloned and expressed in E. coli. A base change, a854>c, has been found in 85% of the 34 Canavan alleles tested so far, which results in a missense glu285>ala mutation that is predicted to be part of the catalytic domain of aspartoacylase. Several additional mutations have also been identified. The invention therefore provides nucleic acid sequences, genes, polypeptides, antibodies, vectors containing the gene, host cells transformed with vectors containing the gene, animal models for the disease, methods for expressing the polypeptide, genetic screening methods and kits, diagnostic methods and kits, methods of treating Canavan disease and methods of genetic therapy for the disease.
摘要翻译：卡纳万病是常染色体隐性遗传性白血病，是由天冬氨酸酶缺乏引起的脑中N-乙酰天冬氨酸积累引起的。跨越1,435bp的人天冬酰胺酶（ASP）cDNA已被克隆并在大肠杆菌中表达。在迄今为止测试的34只卡纳万等位基因中，85％的基因变异已经发现，这导致了预测为天冬酰胺酶催化结构域的一部分的错义glu285> ala突变。还鉴定了另外几个突变。因此，本发明提供核酸序列，基因，多肽，抗体，含有该基因的载体，用含该基因的载体转化的宿主细胞，用于该疾病的动物模型，表达多肽的方法，遗传筛选方法和试剂盒，诊断方法和试剂盒治疗卡万那病的方法和疾病遗传治疗方法。

摘要： A method for enhancing the efficiency of transduction of a recombinant AAV into a target cell is provided. The target cell is infected with a recombinant adeno-associated virus comprising a selected transgene under the control of regulatory sequences. The infected cell is contacted with an agent which facilitates the conversion of single stranded recombinant virus to its double stranded form. When this conversion occurs in the target cell, enhanced transduction of the recombinant virus into said target cell results. The agent can be a helper virus providing a gene which facilitates the conversion, or an agent to which the infected cell is exposed, which facilitates the conversion. In a similar manner, a novel recombinant AAV is provided which contains the facilitating gene and the transgene. The methods may be performed ex vivo or in vivo.
