摘要

We previously found that gene transduction by adeno-associated virus (AAV) vectors in cell culture can be stimulated over 100-fold by treatment of the target cells with agents that affect DNA metabolism, such as irradiation or topoisomerase inhibitors. Here we show that previous γ-irra- diation increased the transduction rate in mouse liver by up to 900-fold, and the topoisomerase inhibitor etoposide in- creased transduction by about 20-fold. Similar rates of hepatic transduction were obtained by direct injection of the liver or by systemic delivery via tail vein injection.
