hnRNPA1 impedes snakehead vesiculovirus replication via competitively disrupting viral phosphoprotein-nucleoprotein interaction and degrading viral phosphoprotein.

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
Heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1) plays an important role in regulating the replication of many viruses. However, it remains elusive whether and how hnRNPA1 regulates fish virus replication. In this study, the effects of twelve hnRNPs on the replication of snakehead vesiculovirus (SHVV) were screened. Three hnRNPs, one of which was hnRNPA1, were identified as anti-SHVV factors. Further verification showed that knockdown of hnRNPA1 promoted, while overexpression of hnRNPA1 inhibited, SHVV replication. SHVV infection reduced the expression level of hnRNPA1 and induced the nucleocytoplasmic shuttling of hnRNPA1. Besides, we found that hnRNPA1 interacted with the viral phosphoprotein (P) via its glycine-rich domain, but not with the viral nucleoprotein (N) or large protein (L). The hnRNPA1-P interaction competitively disrupted the viral P-N interaction. Moreover, we found that overexpression of hnRNPA1 enhanced the polyubiquitination of the P protein and degraded it through proteasomal and lysosomal pathways. This study will help understanding the function of hnRNPA1 in the replication of single-stranded negative-sense RNA viruses and providing a novel antiviral target against fish rhabdoviruses.
