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

backgroundThe dysfunction of osteoblasts has been identified as a pivotal contributor to bone erosion in rheumatoid arthritis (RA). Emerging evidence shows long non-coding RNAs (lncRNAs) as important regulators in various pathological processes, including RA. However, the specific regulatory mechanisms of lncRNAs in osteoblast dysfunction of RA remain poorly understood and worth further investigation.

methodsCollagen induced arthritis (CIA) rat model was established, tarsal tissue was isolated for sequencing of lncRNAs. The differentially expressed lncRNA was screened and verified in vivo and in vitro. The target microRNA of lncRNA and the target protein of microRNA were predicted by bioinformatics analysis and validated. The biology function of the lncRNA and microRNA was further investigated by knockdown or overexpression experiment in murine osteoblastic cell MC3T3-E1.

resultsLncRNA MIAT was highly expressed in tarsal tissue and serum of CIA rat as well as TNF-α-induced osteoblasts, and its high expression was negatively correlated with the expression of bone formation marker osteocalcin. Functionally, knockdown of lncRNA MIAT promoted the proliferation and mineralization of osteoblasts. Mechanistically, lncRNA MIAT directly bound to let-7i-5p and exerted a negative regulatory influence on its expression. CKIP-1 was a target of let-7i-5p. Overexpression of let-7i-5p promoted osteoblast proliferation and mineralization by targeting CKIP-1.

conclusionsTaken together, this study demonstrated that lncRNA MIAT was involved in the regulation of osteoblast proliferation and mineralization through the lncRNA MIAT/let-7i-5p/CKIP-1 axis in RA.
