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

backgroundVEPH1 is amplified in several cancers including ovarian but its impact on tumour progression is unknown. Previous work has shown that VEPH1 inhibits TGFβ signalling while its Drosophila ortholog increases tissue growth, raising the possibility that VEPH1 could impact tumour growth or progression.

methodsA CRISPR approach was used to disrupt VEPH1 expression in ovarian cancer ES-2 cells, while VEPH1-negative SKOV3 cells were stably transfected with VEPH1 cDNA. The impact of altered VEPH1 expression was assessed using in vitro and in vivo assays and mechanistic studies were performed in vitro.

resultsVEPH1 expression in SKOV3 cells resulted in a reduced tumour growth rate associated with increased necrotic area, and decreased microvessel density and VEGF-A levels relative to tumours formed by mock-transfected cells. VEPH1 expression also decreased VEGFA and IL8 expression in SKOV3 cells and was associated with decreased activated AKT levels. These effects were not observed in ES-2 cells, which bear a BRAF

conclusionsVEPH1 expression in SKOV3 ovarian cancer cells inhibits AKT activation to decrease VEGFA and IL8 expression, which leads to decreased tumour vascularisation and progression.
