Double-stranded RNA induces antiviral transcriptional response through the Dicer-2/Ampk/FoxO axis in an arthropod.

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
Invertebrates mainly rely on sequence-specific RNA interference (RNAi) to resist viral infections. Increasing studies show that double-stranded RNA (dsRNA) can induce sequence-independent protection and that Dicer-2, the key RNAi player that cleaves long dsRNA into small interfering RNA (siRNA), is necessary for this protection. However, how this protection occurs remains unknown. Herein, we report that it is caused by adenosine triphosphate (ATP)-hydrolysis accompanying the dsRNA-cleavage. Dicer-2 helicase domain is ATP-dependent; therefore, the cleavage consumes ATP. ATP depletion activates adenosine monophosphate-activated protein kinase (Ampk) and induces nuclear localization of Fork head box O (FoxO), a key transcriptional factor for dsRNA-induced genes. siRNAs that do not require processing cannot activate the transcriptional response. This study reveals a unique nonspecific antiviral mechanism other than the specific RNAi in shrimp. This mechanism is functionally similar to, but mechanistically different from, the dsRNA-activated antiviral response in vertebrates and suggests an interesting evolution of innate antiviral immunity.
