MicroRNA miR-509 Regulates ERK1/2, the Vimentin Network, and Focal Adhesions by Targeting Plk1.
Article in Scientific reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
Polo-like kinase 1 (Plk1) has been implicated in mitosis, cytokinesis, and proliferation. The mechanisms that regulate Plk1 expression remain to be elucidated. It is reported that miR-100 targets Plk1 in certain cancer cells. Here, treatment with miR-100 did not affect Plk1 protein expression in human airway smooth muscle cells. In contrast, treatment with miR-509 inhibited the expression of Plk1 in airway smooth muscle cells. Exposure to miR-509 inhibitor enhanced Plk1 expression in cells. Introduction of miR-509 reduced luciferase activity of a Plk1 3'UTR reporter. Mutation of miR-509 targeting sequence in Plk1 3'UTR resisted the reduction of the luciferase activity. Furthermore, miR-509 inhibited the PDGF-induced phosphorylation of MEK1/2 and ERK1/2, and cell proliferation without affecting the expression of c-Abl, a tyrosine kinase implicated in cell proliferation. Moreover, we unexpectedly found that vimentin filaments contacted paxillin-positive focal adhesions. miR-509 exposure inhibited vimentin phosphorylation at Ser-56, vimentin network reorganization, focal adhesion formation, and cell migration. The effects of miR-509 on ERK1/2 and vimentin were diminished in RNAi-resistant Plk1 expressing cells treated with miR-509. Taken together, these findings unveil previously unknown mechanisms that miR-509 regulates ERK1/2 and proliferation by targeting Plk1. miR-509 controls vimentin cytoskeleton reorganization, focal adhesion assembly, and cell migration through Plk1.
