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

purposeTo investigate the influence of the histone deacetylase inhibitor valproic acid (VPA) on SMAD4 expression and invasive ability of prostate cancer cell lines.

methodsDU145 and PC3 cell lines were treated with 0, 2, and 5 mMol/l of VPA; invasion of DU145 and PC3 cells were then examined by transwell assay. Immunohistochemistry and Western blot were used to examine SMAD4 protein expression in DU145 and PC3 cells.

resultsCompared with controls, VPA significantly suppressed invasiveness in both PC3 and DU145 cells in a dose-dependent way (P < 0.05). VPA also inhibited AKT protein (which was regarded as an effective indicator here), and meanwhile, SMAD4 expression was down-regulated after VPA treatment in a dose-dependent manner in both DU145 (P < 0.05) and PC3 (P < 0.01) cells.

conclusionsValproic acid could suppress invasiveness of prostate cancer cell lines PC3 and Du145, possibly through multiple pathways other than the SAMD4 pathway. This implies that VPA treatment combined with other SMAD4 enhancers could form a basis for a novel prostate cancer treatment.
