Molecular network of miR-1343 regulates the pluripotency of porcine pluripotent stem cells via repressing OTX2 expression.
Article in RNA biology, 2019. 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
Porcine OTX2 was found to be highly activated in porcine iPS cells (piPSCs) that were reported by different laboratories worldwide. To reveal the regulatory function of OTX2 in porcine reprogrammed cells, we screened porcine miRNA-seq databases and found two miRNAs, miR-1343 and miR-545, that could specifically bind to 3'UTR of OTX2 and suppress endogenous OTX2 expression in piPSCs. Knockdown of OTX2 by miR-1343 and miR-545 could significantly increase the expression of SOX2 and ESRRB, but did not alter the expressions of OCT4 and KLF4, and improve the pluripotency of piPSCs. The promoter-based assays showed that OTX2 potentially bound to the promoter region of SOX2 and ESRRB and suppressed their expression. On the other hand, SOX2 could interact with OTX2 promoter. Ectopic expression of SOX2 could significantly decrease OTX2 promoter activity, showing that there is a negative feedback loop between SOX2 and OTX2. Additionally, SOX2 and ESRRB significantly stimulated miR-1343 expression in piPSCs, but OTX2 down regulated the expression of miR-1343 in either direct or indirect manners. In summary, this study demonstrates that there is a regulatory network mediated by miR-1343, in which downregulation of OTX2 by miR-1343 can elevate the expression of pluripotent genes that were then sustain the pluripotency of piPSCs.
