The mechanism of sevoflurane affecting ovarian cancer cell proliferation and migration by regulating RNA methylase TRDMT1 to activate the β-catenin pathway.

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
objectiveSevoflurane (Sevo), a commonly used inhalant anesthetic clinically, is associated with a worsened cancer prognosis, and we investigated its effect on RNA methylase tRNA aspartic acid methyltransferase 1 (TRDMT1) expression and ovarian cancer (OC) cell malignant phenotypes.
methodsHuman OC cells (OVCAR3/SKOV3) were pretreated with 3.6% Sevo and cultured under normal conditions for 48 h, with their viability assessed. After 2-h Sevo treatment or interference plasmid transfections to down-regulate TRDMT1/adenomatous polyposis coli (APC), changes in TRDMT1, APC and β-catenin expression, cell proliferative activity, cycle, apoptosis, migration, invasion, and 5-methylcytosine (m5C) methylation potential modification sites were evaluated. Additionally, APC mRNA m5C methylation level and stability, the binding of APC mRNA with TRDMT1, the binding intensity of APC and β-catenin, and β-catenin nuclear translocation were detected Lastly, Cyclin D1, cellular-myelocytomatosis viral oncogene (C-myc) and β-catenin protein levels, and ki67-positive rate were assessed.
resultsSevo treatment boosted cell cycle, proliferation, migration and invasion, suppressed apoptosis and APC expression, and up-regulated C-myc, β-catenin, TRDMT1 and Cyclin D1 levels. Silencing TRDMT1 or β-catenin partially averted Sevo-mediated promotion effects on cell malignant biological behaviors. Lowly-expressed APC annulled the effect of silencing TRDMT1 and promoted cell malignant behaviors. Sevo enhanced APC mRNA m5C modification and degradation and activated the APC/β-catenin pathway by increasing TRDMT1, thus encouraging OC growth in vivo.
conclusionsSevo stimulated APC m5C modification and curbed its expression by up-regulating TRDMT1, which in turn activated the β-catenin pathway to stimulate OC cell cycle, invasion, proliferation, and migration and to suppress apoptosis.
