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

Molecular studies of human noroviruses (NoV) have been hampered by the lack of a permissive cell culture system. We have developed a sensitive and reliable mammalian cell-based assay for the human NoV GII.4 strain RNA-dependent RNA polymerase (RdRp). The assay is based on the finding that RNAs synthesized by transiently expressed RdRp can stimulate retinoic acid-inducible gene I (RIG-I)-dependent reporter luciferase production via the beta interferon promoter. Comparable activities were observed for the murine norovirus (MNV) RdRp. RdRps with mutations at divalent metal ion binding residues did not activate RIG-I signaling. Furthermore, both NoV and MNV RdRp activities were stimulated by the coexpression of their respective VPg proteins, while mutations in the putative site of nucleotide linkage on VPg abolished most of their stimulatory effects. Sequencing of the RNAs linked to VPg revealed that the cellular trans-Golgi network protein 2 (TGOLN2) mRNA was the template for VPg-primed RNA synthesis. Small interfering RNA knockdown of RNase L abolished the enhancement of signaling that occurred in the presence of VPg. Finally, the coexpression of each of the other NoV proteins revealed that p48 (also known as NS1-2) and VP1 enhanced and that VP2 reduced the RdRp activity. The assay should be useful for the dissection of the requirements for NoV RNA synthesis as well as the identification of inhibitors of the NoV RdRp.
