The p5 promoter region of the adeno-associated virus type 2 (AAV-2) rep gene has been described as essential for Rep-mediated site-specific integration (RMSSI) of plasmid sequences in human chromosome 19. We report here that insertion of a full-length or minimal p5 element between the viral inverted terminal repeats does not significantly increase RMSSI of a recombinant AAV (rAAV) vector after infection of growth-arrested or proliferating human cells. This result suggests that the p5 element may not improve RMSSI of rAAV vectors in vivo.
腺相关病毒2型(AAV-2)rep基因的p5启动子区域已被描述为Rep介导的质粒序列在人染色体19中位点特异性整合(RMSSI)所必需的。我们在此报告,在生长停滞或增殖的人细胞感染后,在病毒反向末端重复序列之间插入全长或最小p5元件不会显著增加重组腺相关病毒(rAAV)载体的RMSSI。这一结果表明,p5元件可能无法在体内改善rAAV载体的RMSSI。
