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

The effects of valproic acid (VPA) on the viability, apoptosis, and invasiveness of two glioma cells (A172 and T98G) and the underlying mechanisms were studied. VPA induced cytotoxicity and apoptosis, and suppressed the invasiveness of both cells. VPA increased the activity of matrix metalloproteinase-2 (MMP-2) and MMP-9 in A172 cells, but decreased it in T98G cells. siRNA blockade of reversion-inducing cysteine-rich protein with Kazal motifs (RECK) expression partially reversed VPA-mediated effects in T98G cells, but had no effect on A172 cells. VPA increased the expression of phospho-JNK1 and phospho-ERK1/2 in A172 cells, but decreased it in T98G cells. Inhibition of JNK1 and/or ERK1/2 partially reversed the VPA effects in A172 cells. In conclusion, the effects of VPA (loss of viability, increased apoptosis, and decreased invasiveness) are, at least partly, mediated through the RECK-MMPs pathway in T98G cells and the mitogen-activated protein kinase pathways in A172 cells. The action of VPA seems to be cell type-specific in glioma cells.
