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 multiforme (GBM) is the most common malignant glioma, which has high proliferative rate and an extremely invasive phenotype. Major limitations in the effective treatment of malignant gliomas are the proliferation and infiltration into the surrounding brain tissue. Although studies have shown that various stimuli promote glioma cell proliferation and invasion, the underlying mechanisms remain largely unknown. Glioma cells secrete significant amount of glutamate into surrounding tissue and intracellular signaling is thought to be initiated upon glutamate-induced modulation of the ion channels in GBM cells. The objective of the study was to investigate the effect of activation of NMDA (N-methyl-D-aspartate) receptors of glutamate on gelatinase subfamily MMPs and on proliferation of glioma cells. U251MG and U87MG cell lines were maintained in Dulbecco's Modified Eagle's Medium. Proliferation assay was investigated by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, a yellow tetrazole (MTT) assay. Matrix metalloproteinase (MMP)-2 and MMP-9 activity was investigated by gelatin zymography assay. We demonstrate that activated NMDA receptors (NMDAR) increased the activity of MMP-2 only in U251MG glioma cells at concentrations of 100 and 200 μM and increased the proliferation of both U87MG and U251MG glioma cells at concentrations of 50, 100, 150 and 200 μM. Inhibition of NMDAR using MK-801, a non-competitive antagonist of the NMDAR, significantly inhibited the effect of activation of NMDAR on MMP-2 activity and on proliferation. We conclude that NMDA receptor activation has role in activity of MMP-2 and proliferation of glioma cells.
