Genome-wide identification of binding sites for Kaposi's sarcoma-associated herpesvirus lytic switch protein, RTA.
Article in Virology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 47 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
Kaposi's sarcoma-associated herpesvirus (KSHV) replication and transcription activator (RTA) encoded by ORF50 is a lytic switch protein for viral reactivation from latency. The expression of RTA activates the expression of downstream viral genes, and is necessary for triggering the full viral lytic program. Using chromatin immunoprecipitation assay coupled with a KSHV whole-genome tiling microarray (ChIP-on-chip) approach, we identified a set of 19 RTA binding sites in the KSHV genome in a KSHV-infected cell line BCBL-1. These binding sites are located in the regions of promoters, introns, or exons of KSHV genes including ORF8, ORFK4.1, ORFK5, PAN, ORF16, ORF29, ORF45, ORF50, ORFK8, ORFK10.1, ORF59, ORFK12, ORF71/72, ORFK14/ORF74, and ORFK15, the two origins of lytic replication OriLyt-L and OriLyt-R, and the microRNA cluster. We confirmed these RTA binding sites by ChIP and quantitative real-time PCR. We further mapped the RTA binding site in the first intron of the ORFK15 gene, and determined that it is RTA-responsive. The ORFK15 RTA binding sequence TTCCAGGAA TTCCTGGAA consists of a palindromic structure of two tandem repeats, of which each itself is also an imperfect inverted repeat. Reporter assay and electrophoretic mobility shift assay confirmed the binding of the RTA protein to this sequence in vitro. Sequence alignment with other RTA binding sites identified the RTA consensus binding motif as TTCCAGGAT(N)(0-16)TTCCTGGGA. Interestingly, most of the identified RTA binding sites contain only half or part of this RTA binding motif. These results suggest the complexity of RTA binding in vivo, and the involvement of other cellular or viral transcription factors during RTA transactivation of target genes.
