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

backgroundStromal cells, including cancer-associated myofibroblasts (CAMs), are recognised to be determinants of cancer progression, but the mechanisms remain uncertain. The chemokine-like protein, chemerin, is upregulated in oesophageal squamous cancer (OSC) CAMs compared with adjacent tissue myofibroblasts (ATMs). In this study, we hypothesised that chemerin stimulates OSC cell invasion.

methodsExpression of the chemerin receptor, ChemR23, in OSC was examined by immunohistochemistry. The invasion of OSC cells was studied using Boyden chambers and organotypic assays, and the role of chemerin was explored using siRNA, immunoneutralisation and a ChemR23 receptor antagonist. Matrix metalloproteinases (MMPs) were detected by western blot, enzyme assays or immunohistochemistry.

resultsImmunohistochemistry indicated expression of the putative chemerin receptor ChemR23 in OSC. It was also expressed in the OSC cell line, OE21. Chemerin stimulated OE21 cell migration and invasion in Boyden chambers. Conditioned medium (CM) from OSC CAMs also stimulated OE21 cell invasion and this was inhibited by chemerin immunoneutralisation, the ChemR23 antagonist CCX832, and by pretreatment of CAMs with chemerin siRNA. In organotypic cultures of OE21 cells on Matrigel seeded with either CAMs or ATMs, there was increased OE21 cell invasion by CAMs that was again inhibited by CCX832. Chemerin increased MMP-1, MMP-2 and MMP-3 abundance, and activity in OE21 cell media, and this was decreased by inhibiting protein kinase C and p44/42 MAPK kinase but not PI-3 kinase.

conclusionsThe data indicate that OSC myofibroblasts release chemerin that stimulates OSC cell invasion. Treatments directed at inhibiting chemerin-ChemR23 interactions might be therapeutically useful in delaying progression in OSC.
