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

Nonalcoholic fatty liver disease (NAFLD) is one of the most prevalent chronic liver disorders that is featured by the extensive deposition of fat in the hepatocytes. Current treatments are very limited due to its unclear pathogenesis. Here, we investigated the function of circ_0057558 and miR-206 in NAFLD. High-fat diet (HFD) feeding mouse was used as an in vivo NAFLD model and long-chain-free fatty acid (FFA)-treated liver cells were used as an in vitro NAFLD model. qRT-PCR was used to measure levels of miR-206, ROCK1 mRNA, and circ_0057558, while Western blotting was employed to determine protein levels of ROCK1, p-AMPK, AMPK, and lipogenesis-related proteins. Immunohistochemistry were performed to examine ROCK1 level. Oil-Red O staining was used to assess the lipid deposition in cells. ELISA was performed to examine secreted triglyceride (TG) level. Dual-luciferase assay was used to validate interactions of miR-206/ROCK1 and circ_0057558/miR-206. RNA immunoprecipitation was employed to confirm the binding of circ_0057558 with miR-206. Circ_0057558 was elevated while miR-206 was reduced in both in vivo and in vitro NAFLD models. miR-206 directly bound with ROCK1 3'-UTR and suppressed lipogenesis and TG secretion through targeting ROCK1/AMPK signaling. Circ_0057558 directly interacted with miR-206 to disinhibit ROCK1/AMPK signaling. Knockdown of circ_0057558 or overexpression of miR-206 inhibited lipogenesis, TG secretion and expression of lipogenesis-related proteins. ROCK1 knockdown reversed the effects of circ_0057558 overexpression. Injection of miR-206 mimics significantly ameliorated NAFLD progression in vivo. Circ_0057558 acts as a miR-206 sponge to de-repress the ROCK1/AMPK signaling and facilitates lipogenesis and TG secretion, which greatly contributes to NAFLD development and progression.
