TOR Facilitates the Targeting of the 19S Proteasome Subcomplex To Enhance Transcription Complex Assembly at the Promoters of the Ribosomal Protein Genes.
Article in Molecular and cellular biology, 2018. 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
TOR (target of rapamycin) has been previously implicated in transcriptional stimulation of the ribosomal protein (RP) genes via enhanced recruitment of NuA4 (nucleosome acetyltransferase of H4) to the promoters. However, it is not clearly understood how TOR enhances NuA4 recruitment to the promoters of the RP genes. Here we show that TOR facilitates the recruitment of the 19S proteasome subcomplex to the activator to enhance the targeting of NuA4 to the promoters of the RP genes. NuA4, in turn, promotes the recruitment of TFIID (transcription factor IID, composed of TATA box-binding protein [TBP] and a set of TBP-associated factors [TAFs]) and RNA polymerase II to the promoters of the RP genes to enhance transcriptional initiation. Therefore, our results demonstrate that TOR facilitates the recruitment of the 19S proteasome subcomplex to the promoters of the RP genes to promote the targeting of NuA4 for enhanced preinitiation complex (PIC) formation and consequently transcriptional initiation, hence illuminating TOR regulation of RP gene activation. Further, our results reveal that TOR differentially regulates PIC formation (and hence transcription) at the non-RP genes, thus demonstrating a complex regulation of gene activation by TOR.
