Eukaryotic RNA binding protein hnRNPH1 suppresses influenza A virus replication through interaction with virus NS1 protein.

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
The NS1 protein of influenza A virus (IAV) is a multi-functional protein which can antagonize host immune system and facilitate viral replication by interacting with host factors. However, the novel partners in host cells interacting with NS1 need to be fully elucidated. In the current study, we identified hnRNPH1 as a novel binding partner of NS1 to regulate IAV replication. Notably, overexpression of hnRNPH1 decreased IAV multiplication, while knockdown of hnRNPH1 enhanced IAV replication. hnRNPH1 can interact with NS1 to change the intracellular localization and splicing function of NS1, and impact IAV replication through interacting with p53 to regulate cell apoptosis. In addition, the RBD domain of NS1 and the RRM and NLS regions of hnRNPH1 may be the major sites for their interaction. In summary, our studies identified hnRNPH1 as a novel NS1-binding protein and elucidated its regulatory roles in IAV replication, which will provide new insights into the roles of NS1 binding proteins, and give a reference for anti-IAV therapy based on NS1-host interaction.
