1 · What the graph read from it

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.

2 · The registry

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

Suppression of lytic viral gene expression is a key aspect of the Epstein-Barr virus (EBV) life cycle to facilitate the establishment of latent infection. Molecular mechanisms regulating transitions between EBV lytic replication and latency are not fully understood. Here, we investigated the impact of viral microRNAs on the EBV lytic cycle. Through functional assays, we found that miR-BHRF1-3 attenuates EBV lytic gene expression following reactivation. To understand the miRNA targets contributing to this activity, we performed Ago PAR-CLIP analysis on EBV-positive, reactivated Burkitt's lymphoma cells and identified multiple miR-BHRF1-3 interactions with viral transcripts. Using luciferase reporter assays, we confirmed a miRNA interaction site within the 3'UTR of BZLF1 which encodes the essential immediate early (IE) transactivator Zta. Comparison of >850 published EBV genomes identified sequence polymorphisms within the miR-BHRF1-3 locus that deleteriously affect miRNA expression and function. Molecular interactions between the homologous viral miRNA, miR-rL1-17, and IE transcripts encoded by rhesus lymphocryptovirus were further identified. Our data demonstrate that regulation of IE gene expression by a BHRF1 miRNA is conserved among lymphocryptoviruses, and further reveal virally-encoded genetic elements that orchestrate viral antigen expression during the lytic cycle.
