    摘要: 본 발명은 (a) 동물세포에서 작동가능한 프로모터 및 (b) 상기 프로모터에 작동적으로 결합된(operatively linked to) 서열목록 제1서열의 E1 코딩 변형 유전자 서열을 포함하는 발현 컨스트럭트가 지놈 DNA에 도입된 세포주에 관한 것이다. 본 발명에 따르면, 본 발명의 세포주는 복제 가능 아데노바이러스(RCA)의 생산 가능성이 낮은, 신규한 아데노바이러스 생산 세포주이다. 본 발명의 아데노바이러스 생산 세포주는 종래 아데노바이러스 생산 세포주와 비교하여 상동재조합(homologous recombination)으로 인한 RCA의 생성 가능성이 낮으며, 이로 인해, 아데노바이러스를 이용한 유전자치료 시 필요한 바이러스의 양을 조절할 수 있고, 아데노바이러스의 과잉생산으로 인한 조직손상 및 독성작용을 저지할 수 있다. 또한, 종래 아데노바이러스 생산 세포주인 HEK293 세포와 비교하여 우수한 아데노바이러스 생산능을 나타내어, 시간- 및 비용- 경제적인 복제 불능 아데노바이러스를 생산할 수 있다. 따라서 본 발명의 세포주는 복제 불능 아데노바이러스를 효율적으로 생산하고 유전자 치료시 안전한 유효량의 아데노바이러스를 제공할 수 있다.

    摘要: The instant invention has developed viral vectors encoding a mutant bacterial cytosine deaminase (bCD) gene, which have a higher affinity for cytosine than wild type bCD (bCDwt) The purpose of the present invention was to evaluate cytotoxicity in vitro and therapeutic efficacy in vivo of these vectors in combination with the prodrug 5-FC and ionizing radiation against human glioma The present study demonstrates that infection with the viral vector expressing the mutant cytosine deaminase gene resulted in increased 5-FC-med?ated cell killing, compared with vectors expressing the wild-type gene Furthermore, a significant increase in cytotoxicity following infection with viral vector expressing the mutant cytosine deaminase gene and radiation treatment of glioma cells in vitro was demonstrated as compared to infection with viral vector expressing the wild-type gene Animal studies showed significant inhibition of subcutaneous or intracranial tumor growth of D54MG glioma xenografts by the combination of AdbCD-D314A/5-FC with ionizing radiation as compared with either agent alone, and with AdbCDwt/5-FC plus radiation

    摘要: A method for providing an adenovirus from a serotype which does not grow efficiently in a desired cell line with the ability to grow in that cell line is described. The method involves replacing the left and right termini of the adenovirus with the corresponding termini from an adenovirus which grow efficiently in the desired cell line. At a minimum, the left terminus spans the (5') inverted terminal repeat, the left terminus spans the E4 region and the (3') inverted terminal repeat. The resulting chimeric adenovirus contains the internal regions spanning the genes encoding the penton, hexon and fiber from the serotype which does not grow efficiently in the desired cell. Also provided are vectors constructed from novel simian adenovirus sequences and proteins, host cells containing same, and uses thereof.

    摘要: The present invention addresses the need to improve the yield of adenovirus when grown in cell culture systems. In particular, it has been demonstrated that for adenovirus, the use of infection temperatures lower than 37°C in a cell culture system results in improved yields of adenovirus. In addition, it has been demonstrated that when host cells are grow in a bioreactor, initiating adenovirus infection by diluting the host cells with fresh media and adenovirus results in improved yield of adenovirus. Methods of adenoviral production and purification using infection temperatures less than 37°C are disclosed. Methods of adenoviral production and purification wherein the host cells are grown in a bioreactor and adenovirus infection is initiated by diluting the host cells with fresh media and adenovirus are also disclosed.
