miR-18a Inhibitor Suppresses Leukemia Cell Proliferation by Upregulation of PTEN Expression.
Article in Medical science monitor : international medical journal of experimental and clinical research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
BACKGROUND Leukemia is common in aging adults and has very high mortality worldwide. The present study was designed to investigate the therapeutic efficacy of miR-18a inhibitor against WEHI-3 and THP-1 leukemia cells. MATERIAL AND METHODS The changes in miR-18a inhibitor-transfected WEHI-3 and THP-1 cell proliferative potential was measured by use of the Cell Counting Kit-8 assay. Apoptotic changes were analyzed by electron microscopy, and evaluation of PI3K, AKT, mTOR, and PTEN expression was assessed by RT-qPCR assay. RESULTS Transfection of miR-18a inhibitor significantly (P<0.05) suppressed the proliferative potential of WEHI-3 and THP-1 cells. The WEHI-3 cells showed the presence of characteristic apoptotic bodies on transfection with miR-18a inhibitor at 48 h. Flow cytometry showed that miR-18a inhibitor transfection significantly (P<0.05) increased the WEHI-3 cell percentage in G1 phase. The transfection of miR-18a inhibitor significantly (P<0.05) promoted apoptosis in WEHI-3 cells. In WEHI-3 cells, miR-18a inhibitor transfection markedly suppressed the expression of PI3K, AKT, and mTOR mRNA. The expression of PTEN mRNA was significantly (P<0.05) upregulated by miR-18a inhibitor transfection in WEHI-3 cells. CONCLUSIONS The present study investigated the therapeutic efficacy of miR-18a inhibitor against WEHI-3 and THP1 leukemia cells. The study demonstrated that miR-18a inhibitor suppressed the proliferative potential of WEHI-3 and THP1 cells and activated apoptotic process through upregulation of PTEN mRNA expression. Therefore, miR-18a inhibitor can be of therapeutic importance for the treatment of leukemia.
