Expression of Human Cytomegalovirus IE1 Leads to Accumulation of Mono-SUMOylated PML That Is Protected from Degradation by Herpes Simplex Virus 1 ICP0.

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 countermeasure the host cellular intrinsic defense, cytomegalovirus (CMV) and herpes simplex viruses (HSV) have evolved the ability to disperse nuclear domain 10 (ND10, aka PML body). However, mechanisms underlying their action on ND10 differ. HSV infection produces ICP0, which degrades the ND10-forming protein PML. Human CMV (HCMV) infection expresses IE1 that deSUMOylates PML to result in dispersion of ND10. It has been demonstrated that HSV ICP0 degraded only the SUMOylated PML, so we hypothesized that HCMV IE1 can protect PML from degradation by ICP0. HCMV IE1-expressing cell lines (U-251 MG-IE1 and HELF-IE1) were used for infection of HSV-1 or transfection of ICP0-expressing plasmid. Multilabeling by immunocytochemistry assay and protein examination by Western blot assay were performed to determine the resultant fate of PML caused by ICP0 in the presence or absence of HCMV IE1. Here, we report that deSUMOylation of human PML (hPML) by HCMV IE1 was incomplete, as mono-SUMOylated PML remained in the IE1-expressing cells, which is consistent with the report by E. M. Schilling, M. Scherer, N. Reuter, J. Schweininger, et al. (J Virol 91:e02049-16, 2017, https://doi.org/10.1128/JVI.02049-16). As expected, we found that IE1 protected PML from degradation by ICP0 or HSV-1 infection. An
