DHTKD1 and neoplasm: Consistent with our in vitro results, tumor sections from both directly treated tumors (lower flanks) as well as untreated tumors (upper flanks) in the Ad.5-TCTV-treated group showed increased staining for MDA-7/IL-24, adenovirus E1A, and Luciferase and the increase in MDA-7/IL-24 and adenovirus E1A was equivalent to that observed in tumor sections from Ad.5-CTV-infected tumors (Figure 7A).
