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

backgroundRheumatoid arthritis (RA) is a chronic autoimmune disease of articular joint damage and elevated synovial hyperplasia. Abnormal proliferation, invasion inflammatory response of rheumatoid fibroblast-like synoviocytes (RA-FLS) play a critical role in RA progression. Mesenchymal stem cell (MSC)-derived exosomal circular RNAs are promising therapeutic manner for disease treatment. This work aimed to decipher the role of exosomal circFBXW7 in RA.

methodsThe expression of circFBXW7, miR-216a-3p, and HDAC4 were detected in clinical RA samples. The RA rat model was established. Isolation and identification of exosomes from MSCs was conducted. The effects of exosomal circFBXW7 on RA was evaluated by qPCR, CCK-8, transwell assays, flow cytometry, Western blotting, ELISA, and immunohistochemical assay. Interaction between miR-216a-3p and circFBXW7 or HDAC4 was determined by luciferase reporter gene assay and RNA pulldown.

resultsExosomal circFBXW7 treatment suppressed proliferation, migration and inflammatory response of RA-FLSs and damage of RA model. CircFBXW7 could directly sponge miR-216a-3p to upregulate the expression of HDAC4. Inhibition of HDAC4 or upregulation of miR-216a-3p abolished the therapeutic function of exosomal circFBXW7. Our data demonstrated that circFBXW7 and HDAC4 were decreased, and miR-216a-3p was elevated in clinical RA sample compared with healthy samples.

conclusionWe concluded that MSC-derived exosomal circFBXW7 suppressed proliferation, migration and inflammatory response of RA-FLSs and damage of RA rats via sponging miR-216a-3p and release the activation of HDAC4. These findings may provide a novel therapeutic target for RA.
