Functional analysis of the UL24 protein of suid herpesvirus 1.
Article in Virus genes, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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 UL24 homologous genes are conserved in alphaherpesviruses. However, the proximity of the UL24 gene and the UL23 gene encoding for thymidine kinase (TK) in the genome of suid herpesvirus 1 (SuHV-1) makes it difficult to mutate UL24 without affecting the expression of the TK gene, and thus functional studies of the UL24 gene have lagged behind. In this study, CRISPR/Cas9 and homologous recombination were adopted to generate UL24 and TK mutant viruses. Deletion of either the UL24 or the TK gene resulted in significantly reduced SuHV-1 replication and spread capacity in Vero cells. However, UL24-deleted virus still maintained a certain degree of lethality in mice, while TK-deleted viruses completely lost their lethality in mice. Similarly, neurovirulence of UL24-deleted virus in mice was not significantly affected compared to parental virus. In comparison, infection with the TK-deleted viruses resulted in significantly reduced neurovirulence and complete loss of lethality. In addition, and for the first time, viral UL24 protein was found to be expressed late during SuHV-1 infection; enhanced green fluorescence protein (eGFP) labeled UL24 protein was shown to be localized in the nucleus via heterologous expression. In conclusion, the UL24 gene of SuHV-1 encodes a nuclear-localized viral protein and acts as a minor virulence-associated factor compared to the TK gene.
