[Effect of phosphoinositide 4-phosphate on invasion and migration of human glioma U87 cells].
Article in Zhongguo dang dai er ke za zhi = Chinese journal of contemporary pediatrics, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the effect of phosphoinositide 4-phosphate (PI4P) on human glioma U87 cells and the mechanism of action of PI4P in the development of human glioma through the overexpression or silencing of PI4P in human glioma U87 cells, and to provide a new target for basic research and clinical treatment of glioma.
methodsLV-Helper1, LV-Helper2, pWPXLd-PI4P, and pLL3.7-shPI4P were used to package pWPXLd-PI4P and pLL3.7-shPI4P lentiviruses. The U87-GFP (PI4P-overexpression control group), U87-GFP-PI4P (PI4P-overexpression experimental group), U87-Scramble (PI4P-silencing control group), and U87-shPI4P (PI4P-silencing experimental group) cell lines were established. Wound-healing assay and Transwell assay were used to evaluate cell migration and invasion, and Western blot was used to measure the expression of PI4P in each group.
resultsWestern blot detected the expression of exogenous PI4P in the U87-GFP-PI4P cell line, and the U87-shPI4P cell line showed reduced expression of PI4P compared with the U87-Scramble cell line in the control group. The U87-GFP-PI4P cell line with PI4P overexpression had a significantly stronger ability of migration than the U87-GFP cell line in the control group (P<0.01); the U87-shPI4P cell line with PI4P silencing had a reduced ability of migration than the U87-Scramble cell line in the control group (P<0.01). The U87 cell line with PI4P overexpression had a significantly stronger invasion ability than the control group (P<0.05); after PI4P silencing, the experimental group showed a significant reduction in invasion ability compared with the control group (P<0.05).
conclusionsIn human glioma U87 cells, PI4P can promote the invasion and migration of glioma cells and may become a new target in the basic research and clinical treatment of glioma.
