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

Histone posttranslational modifications (PTMs) play an essential role in chromatin biology, as they model chromatin structure and recruit enzymes involved in gene regulation, DNA repair, and chromosome condensation. Such PTMs are mostly localized on histone N-terminal tails where, as single units or in a combinatorial manner, they influence chromatin reader protein binding and fine-tune the abovementioned activities. Mass spectrometry (MS) is currently the most adopted strategy to characterize proteins and protein PTMs. We hereby describe the protocols to identify and quantify histone PTMs and their patterns using either bottom-up or middle-down proteomics. In the bottom-up strategy we obtain 5-20 aa peptides by derivatization with propionylation followed by trypsin digestion. The newly generated N-termini of histone peptides can be further derivatized with light or isotopically heavy propionyl groups to increase chromatographic retention and allow multiplexed analyses. Moreover, we describe how to perform derivatization and trypsin digestion of histones loaded into a gel, which is usually the final step of immunoprecipitation experiments. In the middle-down strategy we obtain intact histone tails of 50-60 aa by digestion with the enzyme GluC. This allows characterization of combinatorial histone PTMs on N-terminal tails.
