RACK1 inhibits fowl adenovirus serotype 4 replication by targeting the viral protein Hexon for ubiquitin-proteasome degradation.

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
Fowl adenovirus serotype 4 (FAdV-4), the most pathogenic member of the genus Aviadenovirus, within the family Adenoviridae, primarily induces hepatitis-hydropericardium syndrome (HHS), leading to high morbidity and mortality in chickens. The capsid protein Hexon has been established as a core virulence factor of FAdV-4, but the underlying interaction mechanisms between Hexon and the host remain to be fully elucidated. In this study, we identified that the host protein RACK1 endogenously interacts with the Hexon, and that overexpression of RACK1 significantly inhibited FAdV-4 replication, whereas knockdown of RACK1 markedly promoted this process. Mechanistically, the interaction between RACK1 and Hexon promotes the degradation of Hexon via the ubiquitin-proteasome pathway, thus suppressing FAdV-4 replication. Our results further enrich the understanding of the interaction between Hexon and the host and identifies a novel host factor interaction that may inform future strategies for controlling HHS.
