Replication of Oncolytic Adenoviruses Expressing miR-1 or miR-26b in Cancer Cells
(A) Analysis of adenovirus DNA copy numbers in A549 cells infected with AdΔ24E3-U6, AdΔ24E3-U6.pri-miR-1, or AdΔ24E3-U6.pri-miR-26b by qPCR for adenovirus packaging signal sequences. Data shown are the means of two independent experiments in duplicate. (B) Dose-response cytotoxicity analysis of AdΔ24E3-U6, AdΔ24E3-U6.pri-miR-1, and AdΔ24E3-U6.pri-miR-26b on A549 cells. Data shown are means of two independent experiments in triplicate. (C) Analysis of mature miR-26b-5p levels in A549 cells 32 h after infection with AdΔ24E3-U6, AdΔ24E3-U6.pri-miR-1, or AdΔ24E3-U6.pri-miR-26b. Data shown are means of three independent experiments in duplicate and are given relative to uninfected cells.
