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

Glioblastoma remains among the most devastating cancers with a median survival of less than 15 months and virtually no survival beyond five years. Currently, the treatment of glioma includes surgery, radiation therapy, chemotherapy, and comprehensive treatment. Intrinsic or acquired resistance to TMZ, is one of the greatest obstacles in successful GB treatment, and is thought to be influenced by a variety of mechanisms. The EZH2 gene, which is expressed in various solid tumors, can regulate gene transcription and promote the generation and progression of tumors. Our aim was to investigate the relationship between EZH2 and multidrug-resistance of human glioblastoma cells. In this study, we established TMZ-resistant U251 and U87 clones (U251/TMZ and U87/TMZ cells), which expressed high level of EZH2. Using RNA interference, we demonstrated that the downregulation of Ezh2 expression in U251/TMZ and U87/TMZ cells resulted in apoptosis and a cell cycle arrest in the G1/S phase. Furthermore, the reduced expression of Ezh2 altered the MDR, MRP and BCRP mRNA and protein levels. These findings suggest that EZH2 plays an important part in the development of multidrug resistance and may represent a novel therapeutic target for multidrug-resistant glioblastoma.
