MicroRNA-9 enhances chemotherapy sensitivity of glioma to TMZ by suppressing TOPO II via the NF-κB signaling pathway.
Article in Oncology letters, 2019. 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
Glioma is the most common primary tumor of the central nervous system (CNS) that develops chemotherapy resistance. The microRNA (miRNA) miR-9 is a tissue-specific miRNA of the CNS that may serve a key role in the modulation of chemotherapy sensitivity. The aim of the present study was to investigate the effect of miR-9 on glioma chemotherapy sensitivity by altering the expression of miR-9 in U251 glioma cells by viral transfection and subsequently treating with gradient concentrations of temozolomide (TMZ). Cell viability, apoptosis and the cell cycle were examined, and drug resistance genes were analyzed by western blotting. The role of nuclear factor κB (NF-κB) in this regulation was also examined. The results revealed that the susceptibility of glioma cells to TMZ was enhanced by miR-9 overexpression. When miR-9 and TMZ were applied together, the apoptotic rate and percentage of cells arrested at the G2/M stage were significantly higher compared with either treatment alone. Topoisomerase II expression was suppressed by miR-9 via the NF-κB signaling pathway, which may be responsible for the sensitization. The results of the present study suggested that miR-9 may be a potential target for glioma chemotherapy.
