    摘要: Provided are methods and means to increase the stability and/or the packaging capacity of recombinant adenoviruses, by overexpression of pIX in an adenoviral packaging cell, by retaining at least a part of the E1B-55K region in the recombinant adenoviral vector or by regulating pIX with a heterologous promoter. The invention further relates to methods and means for the production of such adenoviruses on complementing cell lines, wherein the early region 4 open reading frame 6 (E4-orf6) encoding nucleic acid is present in the adenovirus and wherein the E4-orf6 gene product is compatible with one or more products of the E1 gene products in the complementing cell, such that the adenoviral vector can be efficiently produced by the complementing cell.
