Efficacy of a new oncolytic adenovirus armed with IL-13 against oral carcinoma models.
Article in OncoTargets and therapy, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe efficacy of traditional therapies for oral carcinoma (OC) is limited. Oncolytic adenovirus, a novel strategy of cancer therapy, shows potential use in OC treatment. However, its clinical application is limited by pre-existing neutralizing antibodies. Thus, this study aimed to examine the efficacy of a new modified adenovirus against OC in vitro and in vivo. MATERIALS AND
methodsA multiple modified adenovirus (MMAD) armed with IL-13 (MMAD-IL-13) was constructed, and its effect on Cal-27 cells was examined. The potency of MMAD-IL-13 was examined in vitro and in vivo. For in vitro experiment, CCK-8 kit was used to determine the IC50 of MMAD-IL-3 in OC cell lines. For in vivo experiment, Cal-27 xenograft models were used to determine the antitumor effect of MMAD-IL-13. Apoptosis was measured in Cal-27 cells by Western blotting assay. Immunity response was detected in Cal-27 xenograft models 7 days after intratumoral injection with MMAD-IL-13. The potency of MMAD and MMAD-IL-13 was compared in Cal-27 peripheral blood mononuclear cells (PBMCs) models.
resultsMMAD-IL-13 was successfully constructed; the harvested virus could be replicated and they overexpressed human IL-13 in Cal-27 cells. Compared with MMAD, MMAD-IL-13 showed enhanced antitumor effect in vitro by inducing apoptosis and reducing percentage of M2 macrophages in tumor environment in vivo. MMAD-IL-13 also showed potent antitumor effect in Cal-27, SCC-4, and Tca8113 cells in vitro and in Cal-27 xenograft models in vivo. However, MMAD-IL13 did not harm normal human oral epithelial cells in vitro and exhibited no effect on body weight in Cal-27 xenograft models. In Cal-27 PBMC models, MMAD-IL-13 showed stronger antitumor effect than MMAD.
conclusionA new oncolytic adenovirus carrying the human IL-13 gene was constructed. This virus effectively led to remission of tumor development and death of OC cells in vivo and in vitro, showing its potential as a clinical cancer therapy.
