Pseudorabies virus infection reshapes the host epitranscriptome by globally suppressing but selectively elevating specific RNA modifications.

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
RNA modifications are ubiquitous in host cells and hold crucial roles in regulating diverse biological processes. Although the m6A modification during viral infections has garnered significant attention, the involvement of other modifications in such infections remains underexplored. This study was aimed to map out the comprehensive RNA modification profiles in porcine kidney PK-15 cells infected with pseudorabies virus (PRV) at various time points. Throughout the PRV infection, we identified a total of 31 distinct RNA modifications, among which 25 were detected in significantly higher abundances. Our findings indicated that PRV infection largely suppressed the overall level of RNA modifications, but interestingly, it elevated specific modifications, namely Am, Cm, Gm, and Um. Upon deeper investigation, we discovered that PRV infection notably diminished the levels of enzymes related to m1A modification. Collectively, this study uncovers the landscapes of RNA modification in PRV infection, paving the way for further explorations into RNA modifications during herpesvirus infections.
