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

objectivesOur study aimed to explore the effects of quercetin on glioma stem cells in patients with brain tumors.

methodsHuman glioblastoma cell line, U373MG, or glioma stem cell lines, were treated with quercetin. Cell viability was determined by using the cell counting kit 8 assays. Cell apoptosis was determined by using the Annexin- V reagent. Western blotting and qPCR were used to detect the protein and mRNA levels of cyclindependent kinase inhibitor 2A (p16INK4a). Chromatin immunoprecipitation analysis was used to determine the enrichment of H3K27me3 on the p16-INK4 locus with or without quercetin.

resultsTreatment with quercetin inhibited cell viability and induced cell apoptosis in U373MG cells. Moreover, treatment with quercetin inhibited the cell viability of four glioma stem cell lines (G3, G10, G15, and G17) from brain tumor samples at high concentrations while having no obvious effects for the other two glioma stem cell lines (G9 and G21). Treatment with quercetin increased the mRNA and protein levels of p16- INK4 in glioma stem cell lines. The study of the underlying mechanism revealed that treatment with quercetin reduced H3K27me3 (an epigenetic modification to the DNA packaging protein histone H3) levels at the p16-INK4 locus.

conclusionsIn conclusion, quercetin inhibits glioma cell growth by activating p16-INK4 gene expression through epigenetic regulation.
