MiR-493-5p inhibits the malignant development of gliomas via suppressing E2F3-mediated dysfunctions of P53 and PI3K/AKT pathways.
Article in Clinical & translational oncology : official publication of the Federation of Spanish Oncology Societies and of the National Cancer Institute of Mexico, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundGliomas is a major challenge of current medical system, and thousands of people are struggling in the pain of this disease worldwide. In the last decade, the functions of miRNAs have been revealed by many studies, and the intervention on miRNA dysfunctions has been thought as a promising way to counter cancer. MiR-493-5p has been identified as a tumor inhibitor to suppress the progressions of several tumors while its role in gliomas remains unknown. Hence, the study investigated the expression levels of miR-493-5p in glioma tissues and cell lines.
methodsCCK-8 assay, transwell assay and flow cytometry assay were used to observe the effects of miR-493-5p on tumor cells. The downstream targets of miR-493-5p were also searched and verified with online databases and dual-luciferase reporter assay. Moreover, the activities of P53 and PI3K/AKT pathways were also explored by western blot to illustrate the regulation mechanism of miR-493-5p on glioma development.
resultsThe results showed that miR-493-5p was significantly downregulated in pathological tissues and glioma cell lines, and the increased miR-493-5p effectively inhibited the malignant behavior and promoted the apoptosis of glioma cells.
conclusionsE2F3 was confirmed as a target of miR-493-5p, and the effects of miR-493-5p on the phenotype of glioma cells could be partly reversed by E2F3. Besides, it was also found that miR-493-5p could effectively suppress the expression of E2F3 and then improve the dysfunctions of the P53 and PI3K/AKT pathways.
