Antitumor efficacy of viruses on Huh-7 tumor xenografts in nude mice. (A) Ad.SPDD-HCCS1 and Ad.SPDD-HCCS1HA suppress the growth of Huh-7 tumors in vivo. The tumor volumes (mean+SD, n = 6) were measured and estimated every four days. (B) The ratios of surviving mice during the observation period in groups treated with different adenoviruses. (C) H&E staining and immunohistochemical staining of tumor sections using anti-hexon and anti-HA tag antibodies. Representative images are shown at 400 × magnification for the different samples Scale bar = 100 μm. (*: P < 0.05).
