1 · What the graph read from it

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.

2 · The registry

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

Dengue virus (DENV) utilizes host factors throughout its life cycle. In this study, we identified RNA helicase A (RHA), a member of the DEAD/H helicase family, as an important host factor of DENV. In response to DENV2 infection, nuclear RHA protein was partially redistributed into the cytoplasm. The short interfering RNA-mediated knockdown of RHA significantly reduced the amounts of infectious viral particles in various cells. The RHA knockdown reduced the multistep viral growth of DENV2 and Japanese encephalitis virus but not Zika virus. Further study showed that the absence of RHA resulted in a reduction of both viral RNA and protein levels, and the data obtained from the reporter replicon assay indicated that RHA does not directly promote viral protein synthesis. RHA bound to the DENV RNA and associated with three nonstructural proteins, including NS1, NS2B3, and NS4B. Further study showed that different domains of RHA mediated its interaction with these viral proteins. The expression of RHA or RHA-K417R mutant protein lacking ATPase/helicase activity in RHA-knockdown cells successfully restored DENV2 replication levels, suggesting that the helicase activity of RHA is dispensable for its proviral effect. Overall, our work reveals that RHA is an important factor of DENV and might serve as a target for antiviral agents.
