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

Dysregulation of long non-coding RNAs (lncRNAs) plays a fundamental role in the development and progression of osteoarthritis (OA), but the potential functions of lncRNAs in OA were not fully clarified. In the present work, we want to clarify the underlying functions and mechanisms of MIR22HG in OA. qRT-PCR was employed to detect the mRNA expression of MIR22HG, miR-9-3p, and ADAMTS5, while the protein expressions were measured using Western blot. The cell proliferation was examined through CCK8, while apoptosis was used in flow cytometry. Luciferase reporter assay and RNA immunoprecipitation (RIP) assays were undertaken to investigate the binding relationship among MIR22HG, ADAMTS5, and miR-9-3p. MIR22HG was significantly overexpressed in OA cartilages, OA chondrocytes and IL-1β-induced chondrocytes. Functionally, MIR22HG knockdown promoted cell proliferation, suppressed apoptosis, and contributed to downregulation of MMP13 and ADAMTS5 and upregulation of COL2A1 and ACAN in IL-1β-stimulated chondrocytes. Mechanistically, bioinformatic analysis indicated that MIR22HG may serve as a sponge for miR-9-3p and ADAMTS5 may be a potential targeted gene for miR-9-3p, which were subsequently verified through a dual-luciferase reporter assay. Moreover, rescue experiments showed that MIR22HG participated in the regulation of chondrocytes proliferation, apoptosis, and degradation of extracellular matrix via miR-9-3p/ADAMTS5 pathway. In conclusion, our findings illuminated that inhibition of MIR22HG ameliorated IL-1β-induced apoptosis and ECM degradation of human chondrocytes through miR-9-3p/ADAMTS5 pathway, which may provide a potentially promising target for OA treatment.
