Betanodavirus Quantification and IFN I-Antagonism Detection Using Luciferase Reporter Systems Based on Fish mx Promoters.
Article in Journal of fish diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Mx genes display strong and quick induction in response to viral infections, which varies according to the viral virulence; furthermore, mx transcription is blocked by several viruses as part of their immune evasion strategies. Therefore, the level and time course of mx induction reflect virus-host interplay. This idea prompted the development of in vitro experimental systems consisting of cells stably expressing luciferase under the control of fish mx promoters. In this study, two RTG-2 cell lines, expressing luciferase under the control of Senegalese sole (Solea senegalensis) mx (ssmx) promoter, and under the control of gilthead sea bream (Sparus aurata) mx2 (saumx2) promoter, have been applied to study betanodavirus-host interaction. Both systems were inoculated with nervous necrosis virus, NNV, isolates belonging to different genotypes. The combination of both systems has been proved to be useful to detect all of them, although each isolate triggered a characteristic profile in each system. In addition, a protocol to estimate the titre of the RGNNV isolate in sea bass (Dicentrarchus labrax) brain has been established, and a clear dose-dependent antagonistic effect of this NNV isolate was recorded. Thus, both cell lines are useful tools to study betanodavirus-host interaction and, therefore, contribute to developing measures to fight viral infections in aquaculture.
