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

Different mechanisms of transcriptional activation may be required for distinct classes of promoters and cellular conditions. The Epstein-Barr virus (EBV)-encoded transcriptional activator Zta recruits the general transcription factors IID (TFIID) and IIA (TFIIA) to promoter DNA and induces a TATA box-binding protein (TBP)-associated factor-dependent footprint downstream of the transcriptional initiation site. In this study, we investigated the functional significance of TFIID-TFIIA (D-A complex) recruitment by Zta. Alanine substitution mutations in the Zta activation domain which eliminate the ability of Zta to stimulate the D-A complex were examined. These Zta mutants were defective in the ability to activate transcription from an EBV-derived promoter (BHLF1) but activated a highly responsive synthetic promoter (Z7E4T). Both the number of activator binding sites and the core promoter region contribute to the requirement for D-A complex recruitment. These functionally distinct core promoters had significant differences in affinity for TBP and TFIID binding. The D-A complex-recruiting activity of Zta was found to be important for promoter selection in the presence of a competitor template. Conditions which limit TFIID binding to the TATA element or compromise the ability of TFIIA to bind TBP required activator stimulation of the D-A complex. These results indicate that D-A complex recruitment is one of at least two activation pathways utilized by Zta and is the essential pathway for a subset of promoters and conditions which limit TFIID binding to the TATA element.
