Antinociceptive effects of macrophage-derived extracellular vesicles by carrying microRNA-216a.
Article in American journal of translational research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Cancer-induced bone pain (CIBP) represents the pain induced by bone metastases from malignancies. The role of extracellular vesicles (Evs) has been underscored in bone metastasis. However, the function of Evs, especially these derived from M2 macrophages (M2φ-Evs) in CIBP is unclear. Therefore, this investigation aimed to probe the possible antinociceptive effect of M2φ-Evs in CIBP and the underlying mechanism of action. Using the C57bl/6 mice, a CIBP animal model was established by the administration of Walker 256 mammary gland carcinoma cells, followed by M2φ-Evs administration. It was found that CIBP mice treated with M2φ-Evs had significantly reduced nociception and serum inflammatory factors. Microarray sequencing revealed that microRNA-216a (miR-216a) was the most upregulated miRNA in Evs-treated mouse spinal cord tissues. Subsequent bioinformatics, GSEA and KEGG enrichment analyses demonstrated that HMGB1 and TLR4-NF-κB pathway were the downstream effectors of miR-216a and were both downregulated in spinal cord tissues of CIBP mice treated with M2φ-Evs. Rescue experiments displayed that after we reduced miR-216a expression in M2φ-Evs, the antinociceptive effect of M2φ-Evs on CIBP mice was inhibited, and the HMGB1 expression and the TLR4-NF-κB signaling were significantly activated. Together, M2φ-Evs relieve CIBP by carrying miR-216a, which was elicited through the HMGB1/TLR4-NF-κB axis.
