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

Snail transcription factor induces epithelial-mesenchymal transition (EMT) in which the epithelial cells downregulate cell-cell adhesion genes such as E-Cadherin and upregulate mesenchymal genes such as vimentin, leading to increased invasion and migration. Very little is known about the role of Snail in cellular adhesion to the extracellular matrix. We hypothesized that Snail will lead to decreased cellular adhesion to fibronectin and collagen I matrix through integrin regulation, concomitant with increased cell migration. Androgen-independent C4-2 cells, an aggressive subline of androgen-dependent LNCaP cells, exhibited decreased cell adhesion and increased cell migration on fibronectin and collagen I as compared to LNCaP cells, which was reversed by Snail knock down in C4-2 cells. ARCaP and LNCaP prostate cancer cells stably transfected with Snail displayed decreased adhesion and increased cell migration on fibronectin and collagen I as compared to control Neo-transfected cells, which was reversed by Snail knockdown. Flow cytometry analysis revealed a decrease in a5, a2 and b1 integrin expression in ARCaP Snail-transfected cells that was reversed in Snail knock down cells. We also observed an increase in ERK phosphorylation in ARCaP Snail-transfected cells as compared to control ARCaP-Neo cells, and inhibition of the MAPK pathway with UO126 inhibitor in ARCaP Snail-transfected cells abrogated Snail-mediated decrease in cell adhesion and reinduced a5, a2 and b1 integrin expression. Collectively, these studies define a new role for Snail transcription factor in cell adhesion to the ECM, which may be mediated by MAPK signaling, and may be crucial for cell detachment and subsequent metastasis.
