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

backgroundCircular RNA (circRNA) exerts a crucial role in the progression of many cancers, including hepatocellular carcinoma (HCC). However, the function of circ_0001955 in HCC progression has been poorly studied.

aimsElucidating the role and molecular mechanism of circ_0001955 in HCC progression.

methodsQuantitative real-time PCR was employed to detect the expression of circ_0001955 and miR-646. Cell counting kit 8 assay, Ethynyl-2-deoxyuridine assay, flow cytometry, transwell assay, and tube formation assay were conducted to measure cell proliferation, metastasis, angiogenesis and apoptosis. Dual-luciferase reporter assay and biotin-labeled RNA pull-down assay were performed to analyze the interactions among circ_0001955, miR-646 and frizzled class receptor 4 (FZD4). Moreover, animal experiments were performed to examine the influence of circ_0001955 on HCC tumor growth in vivo.

resultsCirc_0001955 was a highly expressed circRNA in HCC tissues and cells. Circ_0001955 knockdown inhibited the proliferation, metastasis, angiogenesis, and enhanced the apoptosis of HCC cells. Meanwhile, miR-646 could be sponged by circ_0001955, and its inhibitor could reverse the negative regulation of circ_0001955 knockdown on HCC progression. Further, FZD4 was a target of miR-646, and its overexpression could invert the inhibition effect of miR-646 mimic on HCC progression. Besides, our results also indicated that circ_0001955 promoted FZD4 expression by sponging miR-646. Animal experiment results showed that circ_0001955 silencing restrained HCC tumor growth in vivo.

conclusionOur findings suggested that circ_0001955 might play a positive role in HCC progression via regulating the miR-646/FZD4 axis, indicating that circ_0001955 might be a potential therapeutic target for HCC.
