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

backgroundThe aims of this study were to detect the level of histone crotonylation in prostate cancer (PCa) tissues, analyze the correlations between its level and clinical stage and grade, and explore the effects of bromodomain-containing protein 4 (BRD4) inhibitors and sodium crotonate on the histone crotonylation in PCa cell lines and on the functions of PCa cells.

methodsPCa tissues from 72 patients and adjacent tissues from 7 patients were collected, and immunohistochemistry was used to measure the level of histone crotonylation. Three human PCa cell lines, PC-3, LNCaP, and C42B, were selected and treated with IC50 value of I-BET762, I-BET726, and CPI-203, respectively. Next, short hairpin RNA (shRNA) transient knockdown was used to inhibit BRD4 expression. Histone crotonylation level and the expression of acetylase were determined by Western blotting. Finally, cell proliferation, migration, and invasion were measured with Cell Counting Kit-8 assay, scratch test, and Transwell test respectively.

resultsThe level of histone crotonylation in PCa tissue was higher than that in adjacent tissues, and histone lysine crotonylation (Kcr) increased with the increasing malignancy of PCa. Treatments with I-BET762, I-BET726, and CPI-203 could inhibit the proliferation, migration, and invasion of PCa cell lines including PC-3, LNCaP, and C42B, and could also regulate the histone crotonylation and androgen receptor signaling pathways via the regulation of BRD4 expression.

conclusionsPCa is closely related to histone crotonylation. Inhibition of BRD4 expression can inhibit the proliferation, migration, and invasion of PCa cells.
