Fig. 2From: Oncolytic therapy with vaccinia virus carrying IL-24 for hepatocellular carcinomaThe expression of VG9-IL-24 mediated IL-24 in vitro. A RT-PCR analyzed transcription of exogenous IL-24 genes in SMMC-7721 cells after treatment with PBS, VG9-IL-24, and VG9-EGFP. B The expression of exogenous IL-24 protein was analyzed by ELISA. Each bar represents the mean ± SD (n = 3). **P < 0.01Back to article page
