a Three days after infection with AdLTR₂EF1α-vec, the cell viability was measured by MTT assay. Values represent mean ± SD (n = 5). b Cells were infected with AdLTR₂EF1α-EGFP at MOI of 1000. The viral replication was monitored under the fluorescence microscope at 12, 24 and 48 h after infection. c Hybrid vector mediated IL-24 transcriptional expression in KB cells by real time RT-PCR analysis. Values represent mean ± SD (n = 3). d Hybrid vector mediated IL-24 transcriptional expression in HaCaT cells. Values represent mean ± SD (n = 3). e The IL-24 protein levels in the culture medium of all samples were determined by ELISA. A significant increase compared with the control is denoted by “***”(P < 0.001). Values represent mean ± SD (n = 3)
