Characterization of post-translational modifications on lysine 9 of histone H3 variants in mouse testis using matrix-assisted laser desorption/ionization in-source decay.
Article in Rapid communications in mass spectrometry : RCM, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
rationalePost-translational modifications (PTMs) of histones result in changes to transcriptional activities and chromatin remodeling. Lysine 9 of histone H3 (H3K9) is subject to PTMs, such as methylation and acetylation, which influence histone activity during spermatogenesis. Characterization strategies for studying PTMs on H3K9 have been developed to provide epigenetic and proteomic information. Proteomic analysis has been used to limited success to study PTMs on H3K9; however, a comprehensive analytical approach is required to elucidate global patterns of PTMs of H3 variants during spermatogenesis.
methodsIntact H3 variants in mouse testis were separated by high-performance liquid chromatography on a reversed-phase column with an ion-pairing reagent. Modifications to H3K9 were identified via top-down analysis using matrix-assisted laser desorption/ionization in source decay (MALDI-ISD).
resultsMono-, di-, and tri-methylations were identified at H3K9 in mouse testis and epididymis. These modifications were also observed in testis-specific histone H3 (H3t). Specifically, tri-methylation was more abundant on H3tK9 than on K9 of other H3 variants.
conclusionsWe introduce a method for rapid, simple, and comprehensive characterization of PTMs on the N-termini of H3 variants using MALDI-ISD. This approach provides novel and useful information, including K9 modifications on H3t, which would benefit epigenetic and proteomic research. © 2016 The Authors.
