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

Malignant glioma invasion into the surrounding brain tissue is still a major problem for any therapeutical methods. Matrix metalloproteinases (MMPs) have been implicated as important factors in this pathological process. In this study, one of the non-steroidal anti-inflammatory drugs (NSAIDs) indomethacin was employed to investigate the effect of inhibition of cell invasion mediated by MMP-2 and MMP-9 in human malignant glioma cell lines, A172, U87MG, U251MG, and U373MG in vitro. MTT assay was firstly examined to determine non-cytotoxic dose range, then gelatin zymography, matrigel invasion assay, migration assay and MMP-2 activity assay for 24 h exposure in indomethacin were employed to assess the inhibitory effect of indomethacin. MTT assay revealed that dose with 0, 50, and 500 microM/ml were non-cytotoxic. Zymography demonstrated: (a) expression of MMP-2 and MMP-9 activity was downregulated along with elevated dose of indomethacin. (b) MMP-2 activity that changed from pro-MMP-2 to active form of MMP-2 in supernatants of cell lines could not be inhibited by indomethacin. Invasion assay disclosed that the number of invading cells through the matrigel were significantly decreased in a dose dependent manner. Migration assay indicated indomethacin did not affect cells migration. MMP-2 activity assay showed the total and active MMP-2 secretion was suppressed by 500 microM/ml of indomethacin. Our present study is the first report on inhibitive effect of indomethacin mediated by MMP-2 and MMP-9 in invasion assay of glioma cell lines. The current study suggested that non-cytotoxic level of indomethacin was able to reduce the cell invasion of malignant gliomas mediated by MMP-2 and MMP-9, but it did not affected on cell motility. It also lowered down the activity of MMP-2 and MMP-9, and could reduce of MMP-2 secretion of cell lines. Thus, high concentration of indomethacin within non-cytotoxic dose might offer a new therapeutic strategy to impair cell invasion of gliomas.
