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

Measles virus (MV) lacking expression of C protein (C(KO)) is a potent activator of the double-stranded RNA (dsRNA)-dependent protein kinase (PKR), whereas the isogenic parental virus expressing C protein is not. Here, we demonstrate that significant amounts of dsRNA accumulate during C(KO) mutant infection but not following parental virus infection. dsRNA accumulated during late stages of infection and localized with virus replication sites containing N and P proteins. PKR autophosphorylation and stress granule formation correlated with the timing of dsRNA appearance. Phospho-PKR localized to dsRNA-containing structures as revealed by immunofluorescence. Production of dsRNA was sensitive to cycloheximide but resistant to actinomycin D, suggesting that dsRNA is a viral product. Quantitative PCR (qPCR) analyses revealed reduced viral RNA synthesis and a steepened transcription gradient in C(KO) virus-infected cells compared to those in parental virus-infected cells. The observed alterations were further reflected in lower viral protein expression levels and reduced C(KO) virus infectious yield. RNA deep sequencing confirmed the viral RNA expression profile differences seen by qPCR between C(KO) mutant and parental viruses. After one subsequent passage of the C(KO) virus, defective interfering RNA (DI-RNA) with a duplex structure was obtained that was not seen with the parental virus. We conclude that in the absence of C protein, the amount of PKR activator RNA, including DI-RNA, is increased, thereby triggering innate immune responses leading to impaired MV growth.
