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

rationaleMisregulation of angiotensin II (Ang II) actions can lead to atherosclerosis and hypertension. Evaluating transcriptomic responses to Ang II in vascular smooth muscle cells (VSMCs) is important to understand the gene networks regulated by Ang II, which might uncover previously unidentified mechanisms and new therapeutic targets.

objectiveTo identify all transcripts, including novel protein-coding and long noncoding RNAs, differentially expressed in response to Ang II in rat VSMCs using transcriptome and epigenome profiling. METHODS AND

resultsDe novo assembly of transcripts from RNA-sequencing revealed novel protein-coding and long noncoding RNAs (lncRNAs). The majority of the genomic loci of these novel transcripts are enriched for histone H3 lysine-4-trimethylation and histone H3 lysine-36-trimethylation, 2 chromatin modifications found at actively transcribed regions, providing further evidence that these are bonafide transcripts. Analysis of transcript abundance identified all protein-coding and lncRNAs regulated by Ang II. We further discovered that an Ang II-regulated lncRNA functions as the host transcript for miR-221 and miR-222, 2 microRNAs implicated in cell proliferation. Additionally, small interfering RNA-mediated knockdown of Lnc-Ang362 reduced proliferation of VSMCs.

conclusionsThese data provide novel insights into the epigenomic and transcriptomic effects of Ang II in VSMCs. They provide the first identification of Ang II-regulated lncRNAs, which suggests functional roles for these lncRNAs in mediating cellular responses to Ang II. Furthermore, we identify an Ang II-regulated lncRNA that is responsible for the production of 2 microRNAs implicated in VSMC proliferation. These newly identified noncoding transcripts could be exploited as novel therapeutic targets for Ang II-associated cardiovascular diseases.
