Negative Regulation of Semaphorin-3A Expression in Peripheral Blood Mononuclear Cells Using MicroRNA-497-5p.
Article in Iranian journal of medical sciences, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundSemaphorin-3A (Sema3A), as a secreted semaphorin, is an immune modulator molecule participating in the pathogenesis of autoimmune diseases. MicroRNAs (miRNAs) modulate the target-gene expression at the post-transcriptional level. It has been proposed that miRNAs may be crucial to the modulation of the function of semaphorins. Previous findings have proven that miR-497-5p is upregulated and Sema3A is downregulated in some autoimmune disorders. Thus, we aimed to examine the presence of any correlation between Sema3A and miR-497-5p in peripheral blood mononuclear cells (PBMCs).
methodsPBMCs were cultured and transfected with miR-497-5p mimic using the X-tremeGENE™ reagent. The expression level of Sema3A was assessed after 48 hours in supernatants and cells via the enzyme-linked immunosorbent assay and quantitative real-time polymerase chain reaction, respectively. Cell viability was evaluated using the methylthiazol tetrazolium assay. All the experiments were done in triplicate, and the statistical analyses were performed with SPSS, version 20. P values equal to or less than 0.05 were considered significant.
resultsWe observed downregulation of the Sema3A gene (P=0.0001) and its secretion (P=0.032) in the PBMCs through miR-497-5p transfection. Moreover, transfection with miR-497-5p mimic and downregulation of Sema3A did not affect the viability of the PBMCs (P=0.061).
conclusionBased on the obtained results, we suggest that miR-497-5p has a high suppressive effect on Sema3A expression and both Sema3A and miR-497-5p can be considered critical targets for further studies on future therapeutic attempts for the treatment of autoimmune diseases such as multiple sclerosis and rheumatoid arthritis.
