Hepatitis C Virus Induces the Ubiquitin-Editing Enzyme A20 via Depletion of the Transcription Factor Upstream Stimulatory Factor 1 To Support Its Replication.
Article in mBio, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Tumor necrosis factor alpha-induced protein 3 (TNFAIP3), also known as A20, is a ubiquitin-editing enzyme capable of ubiquitination or deubiquitination of its target proteins. In this study, we show that hepatitis C virus (HCV) infection could induce the expression of A20 via the activation of the A20 promoter. The induction of A20 by HCV coincided with the loss of upstream stimulatory factor 1 (USF-1), a transcription factor known to suppress the A20 promoter. The role of USF-1 in the regulation of the A20 promoter in HCV-infected cells was confirmed by the chromatin immunoprecipitation (ChIP) assay, and its depletion was apparently mediated by proteasomes, as USF-1 could be stabilized by the proteasome inhibitor MG132 to suppress the A20 expression. As the overexpression of A20 enhanced the replication of HCV and the silencing of A20 had the opposite effect, A20 is a positive regulator of HCV replication. Our further studies indicated that A20 enhanced the activity of the HCV internal ribosome entry site (IRES). In conclusion, our results demonstrated that HCV could induce the expression of A20 via the depletion of USF-1 to enhance its replication. Our study provided important information for further understanding the interaction between HCV and its host cells.
