Effects and mechanism of miR-133a on invasion and migration of lung cancer cells.
Article in American journal of translational research, 2022. 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
objectivesTo study the role of miR-133a expression in the invasion, proliferation, migration, and apoptosis of lung cancer cells and its mechanism.
methodsmiR-133a expression levels in human normal lung epithelial cells (BEAS-2B), H441 cell lines and NSCLC tissues were detected by qPCR. The influence of miR-133a mimics on the migration, proliferation and invasion of H441 cells was examined by CCK-8 assay, transwell migration assay, and invasion assay, respectively. Expression of MMP-9 and LASP1 in H441 cellstreated by miR-133a mimics was determined by western blot. Pearson's test was conducted to study the association of miR-133a expression with clinical characteristics of NSCLC patients. The targeted regulation of miR-133a on LASP1 gene expression was detected by the luciferase reporter gene assay.
resultsmiR-133a expression was decreased in H441 cells in contrast to that in BEAS-2B cells (P<0.05). Compared with para-carcinoma tissues, miR-133a levels were markedly down-regulated in NSCLC tissues. miR-133a overexpression inhibited the invasion, proliferation, and migration ability of H441 cells and promoted cell apoptosis (all P<0.05). MMP-9 expression levels were also reduced in the miR-133a mimic group. Moreover, miR-133a expression levels were correlated with tumor size and TNM stage. miR-133a overexpression decreased the expression of LASP1, which is the targeted gene of miR-133a.
conclusionsmiR-133a overexpression can reduce the invasion, proliferation, migration, and matrix metalloproteinase expression of NSCLC cells and promote cell apoptosis. This may be correlated to targeted down-regulation of LASP1 expression.
