Reduction of infectious bursal disease virus replication in cultured cells by proteasome inhibitors.
Article in Virus genes, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Infectious bursal disease virus (IBDV) is the etiological agent of a highly contagious disease in chickens. In a recent report, proteasome inhibitor MG132 has been shown to completely inhibit IBDV-induced apoptosis. This raises the possibility that the ubiquitin-proteasome pathway may be used by the virus to promote viral replication. In this study, we examined the interplay between IBDV replication and the ubiquitin-proteasome pathway in cultured cells. Treatment of DF-1 cells with the proteasome inhibitors MG132 or lactacystin significantly decreased virus release in the supernatant and prevented virus-induced cytopathic effect. Inhibition of the ubiquitin-proteasome pathway did reduce markedly viral RNA transcription and protein translation but not affect virus internalization. We also demonstrated that IBDV activates caspase pathway via triggering the efflux of cytochrome c in mitochondria into cytosol of infected cells. This activity was dose-dependently reduced by proteasome inhibitor treatment. Taken together, our data suggest that proteasome inhibitor reduces IBDV replication through inhibition of viral RNA transcription and protein synthesis, and thus preventing IBDV-induced apoptosis.
