MCAF1 and Rta-activated BZLF1 transcription in Epstein-Barr virus.
Article in PloS one, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Epstein-Barr virus (EBV) expresses two transcription factors, Rta and Zta, which are involved in the transcriptional activation of EBV lytic genes. This study sought to elucidate the mechanism by which Rta activates transcription of the Zta-encoding gene, BZLF1, through the ZII element in the gene promoter. In a DNA affinity precipitation assay, ATF2 was found to associate with an Rta-interacting protein, MCAF1, at the ZII element. The interaction between Rta, MCAF1, and ATF2 at the same site in the ZII region was further verified in vivo by chromatin immunoprecipitation assay. The complex appears to be crucial for the activation of BZLF1 transcription, as the overexpression of two ATF2-dominant negative mutants, or the introduction of MCAF1 siRNA into 293T cells, were both found to substantially reduce Rta-mediated transcription levels of BZLF1. Moreover, this study also found that the Rta-MCAF1-ATF2 complex binds to a typical AP-1 binding sequence on the promoter of BMRF2, a key viral gene for EBV infection. Mutation of this sequence decreased Rta-mediated promoter activity significantly. Taken together, these results indicate a critical role for MCAF1 in AP-1-dependent Rta activation of BZLF1 transcription.
