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

backgroundGastroesophageal reflux is a risk factor for esophageal adenocarcinoma, and bile acid and its farnesoid X receptor (FXR) have been implicated in esophageal tumorigenesis. The authors investigated the role of FXR expression and activity in esophageal cancer initiation and growth.

methodsFXR expression in esophageal adenocarcinoma tissues was assessed by immunohistochemistry. Knockdown of FXR expression in esophageal cancer cells in vitro and in nude mice xenografts was suppressed by FXR small hairpin RNA (shRNA) and guggulsterone (a natural FXR inhibitor). Esophageal cancer cells were treated with bile acids to demonstrate their effects on growth-promoting genes.

resultsFXR was expressed in 48 of 59 esophageal adenocarcinoma tissues (81.3%), and this overexpression was associated with higher tumor grade, larger tumor size, and lymph node metastasis; however, was inversely associated with retinoic acid receptor-β2 (RAR-β2 ) expression. Knockdown of FXR expression suppressed tumor cell growth in vitro and in nude mouse xenografts. Guggulsterone reduced the viability of esophageal cancer cells in a time-dependent and dose-dependent manner, whereas this effect was diminished after knockdown of FXR expression. Guggulsterone induced apoptosis through activation of caspase-8, caspase-9, and caspase-3 in tumor cells. FXR mediated bile acid-induced alterations of gene expression, eg, RAR-β2 and cyclooxygenase-2 (COX-2).

conclusionsInhibition of FXR by FXR shRNA or guggulsterone suppressed tumor cell viability and induced apoptosis in vitro, and it reduced tumor formation and growth in nude mouse xenografts. FXR also mediated bile acid-induced alterations of cell growth-related genes in esophageal cancer cells.
