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

The transcriptional coactivator paralogues p300 and CBP contain acetyltransferase domains (HAT) and catalyze the lysine acetylation of histones and other proteins as an important aspect of their functions. Prior studies revealed that the basic leucine zipper domain (b-ZIP) of transcription factor ATF-2 (also called CRE-BP1) can interact with the CBP HAT domain. In this study, we have examined the ATF-2 b-ZIP interaction with the p300 HAT domain and shown that p300 HAT autoacetylation can enhance the binding affinity. Pull-down assays revealed that hyperacetylated p300 HAT is more efficiently retained by immobilized ATF-2 b-ZIP than hypoacetylated p300 HAT. Loop deleted p300 HAT lacking autoacetylation was retained about as well as hyperacetylated p300 HAT, suggesting that the loop and ATF-2 compete for p300 HAT binding. While ATF-2 b-ZIP is a weak inhibitor of hypoacetylated p300 HAT acetylation of a histone H4 peptide, hyperacetylated p300 HAT is much more potently inhibited by ATF-2 b-ZIP. Moreover, we showed that ATF-2 b-ZIP could serve as an acetyltransferase substrate for p300 HAT. Using mass spectrometry, two p300 HAT lysine acetylation sites were mapped in ATF-2 b-ZIP. Immunoprecipitation-Western blot analysis with anti-acetyl-lysine antibody revealed that ATF-2 can undergo reversible acetylation in vivo. Mutational analysis of the two ATF-2 b-ZIP acetylation sites revealed their potential contributions to ATF-2-mediated transcriptional activation. Taken together, these studies suggest multiple roles for protein acetylation in the regulation of transcription by p300/CBP and ATF-2.
