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

Recent studies demonstrate the functions of long non-coding RNAs (lncRNAs) in mediating gene expression at the transcriptional or translational level. Our previous study identified a Sirt1 antisense (AS) lncRNA transcribed from the Sirt1 AS strand. However, its role and regulatory mechanism is still unknown in myogenesis. Here, functional analyses showed that Sirt1 AS lncRNA overexpression promoted myoblast proliferation, but inhibited differentiation. Mechanistically, Sirt1 AS lncRNA was found to activate its sense gene, Sirt1. The luciferase assay provided evidences that Sirt1 AS lncRNA interacted with Sirt1 3' UTR and rescued Sirt1 transcriptional suppression by competing with miR-34a. In addition, RNA stability assay showed that Sirt1 AS lncRNA prolonged Sirt1 mRNA half-life from 2 to 10 h. Ribonuclease protection assay further indicated that it fully bound to Sirt1 mRNA in the myoblast cytoplasm. Moreover, Sirt1 AS overexpression led to less mouse weight than the control because of less lean mass and greater levels of Sirt1, whereas the fat mass and levels of miR-34a were not altered. Based on the findings, a novel regulatory mechanism was found that Sirt1 AS lncRNA preferably interacted with Sirt1 mRNA forming RNA duplex to promote Sirt1 translation by competing with miR-34a, inhibiting muscle formation.
