MiR-25 exerts cardioprotective effect in a rat model of myocardial ischemia-reperfusion injury by targeting high-mobility group box 1.
Article in Journal of the Chinese Medical Association : JCMA, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundWe previously confirmed the targeting of high-mobility group box 1 (HMGB1) by miR-25. This project aims to further investigate whether miR-25 improves myocardial ischemia-reperfusion injury (IRI) in vivo by targeting HMGB1.
methodsA rat model of myocardial IRI was established by the ligation of the left anterior descending coronary artery for 45 minutes followed by 2, 4, or 6 hours reperfusion. The expression of miR-25, HMGB1, and apoptosis-related proteins in the myocardium was determined by quantitative real-time polymerase chain reaction (PCR) and western blotting. The activities of myocardial enzymes and the release of inflammatory cytokines were evaluated by enzyme-linked immunosorbent assay. Evans blue/triphenyltetrazolium chloride double staining was performed to assess infarct size. Myocardial apoptosis was detected by terminal deoxynucleotidyl transferase dUTP nick end labeling staining.
resultsMiR-25 expression was significantly downregulated, while HMGB1 was highly expressed at the mRNA and protein levels in myocardial tissues after induction of the IRI model. MiR-25 agomir administration suppressed the expression of HMGB1 in myocardial tissues. Furthermore, administration of both miR-25 agomir and lentivirus-mediated short hairpin RNA (shRNA) interference targeting HMGB1 sh-HMGB1 resulted in reduced serum myocardial enzyme activities, cytokine secretion, and myocardial apoptosis during myocardial IRI.
conclusionMiR-25 mitigated myocardial IRI-induced damage by targeting HMGB1.
