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

Capillary zone electrophoresis-tandem mass spectrometry (CZE-MS/MS) has attracted attention recently for large-scale top-down proteomics that aims to characterize proteoforms in cells at a global scale and with high throughput. In this work, CZE-MS/MS with ultraviolet photodissociation (UVPD) was evaluated for large-scale top-down proteomics for the first time. Roughly, 600 proteoforms and 369 proteins were identified from a zebrafish brain sample via coupling size exclusion chromatography (SEC) fractionation to CZE-UVPD. The dataset represents one of the largest top-down proteomics datasets using UVPD. Single-shot CZE-UVPD identified 227 proteoforms of 139 proteins from one SEC fraction of the zebrafish brain sample. The SEC-CZE-UVPD system identified zebrafish brain proteoforms in a mass range of 3-21 kDa. The UVPD with 213-nm photons produced reasonably good gas-phase fragmentation of proteoforms. For instance, 75% backbone cleavages were observed for Parvalbumin-7 with about 12-kDa molecular weight. The system detected various post-translational modifications (PTMs) from the zebrafish brain sample, including N-terminal acetylation, trimethylation and myristoylation of N-terminal glycine. Two different proteoforms of calmodulin, with either only N-terminal acetylation or both N-terminal acetylation and K115 trimethylation, were identified in the zebrafish brain sample. To our best knowledge, there is no experimental evidence reported in the literature on the two proteoforms of calmodulin in the zebrafish brain.
