1 · What the graph read from it

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.

2 · The registry

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 investigate the protective effect of mefloquine HCl (MQ) against X-ray irradiation-induced DNA damage in lung epithelial cells.

methodsHuman lung epithelial cells (BEAS-2B) were divided into blank control group, irradiation group, and irradiation+MQ treatment group. The effects of MQ on cell proliferation and radiosensitivity after X-ray irradiation were assessed using CCK-8 assay, EdU-488 assay, and colony formation assay. Apoptosis and cell cycle distribution of BEAS-2B cells with different treatments were detected by flow cytometry. The effect of MQ in promoting DNA double-strand break (DSB) repair was observed using immunofluorescence staining and comet assay, and the molecule ar mechanism was explored using Western blotting, qPCR, and luciferase reporter assays.

resultsMQ at 0-10 μmol/L did not significantly affect BEAS-2B cell viability. Compared to the irradiated cells, treatment with 0-10 μmol/L MQ enhanced the cell viability, and the effect was the most conspicuous at 10 μmol/L. MQ treatment obviously promoted proliferation and increased clonogenic survival rate of irradiated BEAS-2B cells while reducing their radiosensitivity, and significantly lowered cell apoptosis rate following the irradiation. Cell cycle analysis revealed that MQ alleviated G2/M phase arrest induced by irradiation, and comet assay and immunofluorescence staining showed reduced comet tail moment and γH2AX foci formation in irradiation+MQ group. Western blotting and qPCR demonstrated that MQ treatment for 48 h significantly increased CtIP promoter activity and upregulated CtIP expressions at both the mRNA and protein levels.

conclusionsMQ promotes DSB repair in BEAS-2B cells by upregulating CtIP expression and may thus alleviate radiation-induced lung epithelial cell injury.
