Long non-coding RNA MEG3 regulates the progress of osteoarthritis by regulating the miR-34a/Klotho axis.
Article in Annals of translational medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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.
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
Background: Osteoarthritis (OA) is one of the most common chronic diseases today, and its prevalence and incidence are expected to increase as life expectancy increases. By investigating the inhibition of long non-coding RNA maternally expressed gene 3 (lncRNA MEG3) in OA, we hope to provide some new insights into the treatment of osteoarthritis. Methods: By constructing an osteoarthritis model, the knee joint tissue of the model was observed using hematoxylin and eosin staining (HE) and computed tomography (CT). Detection of miR-34a and Klotho expression by fluorescent quantitative polymerase chain reaction (PCR) and Western blot. The lncRNA MEG3 overexpression vector was constructed and transfected into C28/I2 cells. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was used to detect the results of lncRNA MEG3 and miR-34a expression in each group of cells, and Western blot was used to detect the results of Klotho, recombinant fibroblast growth factor 23 (FGF23), B-cell lymphoma-2 (Bcl-2), BCL2-associated X (Bax), Transforming growth factor beta 1 (TGF-β1), cysteinyl aspartate specific proteinase 3 (Caspase3) and cysteinyl aspartate specific proteinase 8 (Caspase8) protein expression. Results: Compared with the control group, HE and CT results showed significant pathological changes in the knee joint of the osteoarthritis model mice. and Klotho expression was significantly decreased and miR-34a expression was significantly increased in the model group (P<0.05). Compared with those in the control group, the expression levels of lncRNA MEG3, Klotho, FGF23, and Bcl-2 decreased significantly and the expression levels of microRNA-34a (miR-34a), Bax, TGF-β1, Caspase 3, and Caspase 8 increased sharply (P<0.05) in the lipopolysaccharides (LPS) group. Meanwhile, lncRNA MEG3 overexpression upregulated the expression of miR-34a, Bax, TGF-β1, Caspase3 and Caspase8, and downregulated the expression of Klotho, FGF23 and Bcl-2. Conclusions: lncRNA MEG3 regulated the expression of FGF23, Bcl-2, Bax, TGF-β1, Caspase 3, and Caspase 8 by regulating the miR-34a/Klotho axis, thereby affecting the progress of OA.
