Expression of miR-31-5p affects growth, migration and invasiveness of papillary thyroid cancer cells.
Article in Endocrine, 2023. 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
purposeIn this study, we evaluated the biological role of miRNA-31-5p in papillary thyroid cancer (PTC).
methodsBy using the real-time PCR, we measured miRNA-31-5p expression levels in 25 PTC tissues and in two human PTC cell lines (K1 and TPC-1). Then, K1 cells were transiently transfected with mirVana inhibitor or mirVana mimic to miRNA-31-5-p. Cell proliferation was determined by MTT and colony formation assays. The in vitro metastatic ability of thyroid cancer cells was evaluated by adhesion, migration and invasion assays. Epithelial mesenchymal transition (EMT) and Hippo pathway related gene and protein levels were evaluated by using the TaqMan™ Gene Expression Assays and western blot analysis, respectively.
resultsWe found a significant increase of miR-31-5-p expression in tumor tissue and in K1 cells harboring the BRAF p.V600E mutation. Knockdown of miR-31-5p determined a reduction of cell proliferation, associated with a significant decrease in cell adhesion, migration and invasion properties. A downregulation of EMT markers and YAP/β-catenin axis was also observed.
conclusionsOur findings suggest that miRNA-31-5p acts as oncogenic miRNA in human thyrocytes and its overexpression may be involved in the BRAF-related tumorigenesis in PTCs, providing new understanding into its pathological role in PTC progression and invasiveness.
