ICP22 of Herpes Simplex Virus 1 Decreases RNA Polymerase Processivity.
Article in Journal of virology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
To determine the role of ICP22 in transcription, we performed precise nuclear run-on followed by deep sequencing (PRO-seq) and global nuclear run-on with sequencing (GRO-seq) in cells infected with a viral mutant lacking the entire ICP22-encoding α22 (US1/US1.5) gene and a virus derived from this mutant bearing a restored α22 gene. At 3 h postinfection (hpi), the lack of ICP22 reduced RNA polymerase (Pol) promoter proximal pausing (PPP) on the immediate early α4, α0, and α27 genes. Diminished PPP at these sites accompanied increased Pol processivity across the entire herpes simplex virus 1 (HSV-1) genome in GRO-seq assays, resulting in substantial increases in antisense and intergenic transcription. The diminished PPP on α gene promoters at 3 hpi was distinguishable from effects caused by treatment with a viral DNA polymerase inhibitor at this time. The ICP22 mutant had multiple defects at 6 hpi, including lower viral DNA replication, reduced Pol activity on viral genes, and increased Pol activity on cellular genes. The lack of ICP22 also increased PPP release from most cellular genes, while a minority of cellular genes exhibited decreased PPP release. Taken together, these data indicate that ICP22 acts to negatively regulate transcriptional elongation on viral genes in part to limit antisense and intergenic transcription on the highly compact viral genome. This regulatory function directly or indirectly helps to retain Pol activity on the viral genome later in infection.
