LncRNA LINC00520 Predicts Poor Prognosis and Promotes Progression of Lung Cancer by Inhibiting MiR-3175 Expression.
Article in Cancer management and research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeThe aim of this study was to study the roles and potential mechanism of LINC00520 in the progression of lung cancer.
methodsThe expression of LINC00520 and miR-3175 in lung cancer tissues and cells was detected by qRT-PCR. The relationship between LINC00520 level and disease stage was also calculated. Kaplan-Meier survival curve was drawn to observe the survival difference between high and low expression patients. Lipofectamine 2000 was used to transfect siLINC00520, miR-3175 inhibitor and their controls in lung cancer cells. CCK8 and colony formation assay were processed for cell proliferation. Transwell assay was undertaken for migration and invasion of lung cancer cells. MiRDB predicts the combination of LINC00520 and miR-3175. Luciferase and RNA pulldown assay were applied to verify the binding site. Correlation analysis of miR-3175 and LINC00520 expression in lung cancer tissues was shown.
resultsLINC00520 was highly expressed in lung cancer tissues and cells. Patients at III+IV stage were always with higher LINC00520 level than patients at I+II stage. Patients with high expression of lncRNA LINC00520 have short survival time (hazard ratio=1.7). Knockdown of LINC00520 inhibited proliferation, invasion and migration of lung cancer cells. LINC00520 targeted and negatively regulated miR-3175 (r=-0.528; P<0.001). MiR-3175 inhibitor rescued the effect of si-LINC00520 on lung cancer progression.
conclusionLncRNA LINC00520 could predict poor prognosis and promote progression of lung cancer by inhibiting miR-3175 expression.
