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

purposeAltered expression and/or function of ribosomal RNA (rRNA)-binding proteins CUGBP2/CELF2 might influence post-transcriptional regulation of the HO-1- and COX-2-mediated cytoprotective pathways and represents an important therapeutic target. The aim of this study was to assess the effects of CUGBP2-mediated post-transcriptional regulation of COX-2 and HO-1 in pancreatic cancer cells in regard of response to gemcitabine (GEM) treatment.

methodsExpression of CUGBP2, COX-2, and HO-1 was evaluated using qRT-PCR and Western blot methods. Cell viability after treatment with GEM and/or curcumin and siCUGBP2 was evaluated using MTT and crystal violet tests. RNA immunoprecipitation analysis was used to confirm COX-2 and HO-1 post-transcriptional regulation by CUGBP2 protein.

resultsCUGBP2 expression at the messenger RNA (mRNA) level was 2.2-fold lower (p = 0.007), but HO-1 and COX-2 expression was increased 6.9- (p = 0.023) and 2.3- (p = 0.046) fold in pancreatic cancer tissues. The median survival of patients with low CUGBP2 expression from the lowest tercile was 13.8 months. The median survival of patients in terciles of middle and high CUGBP2 expression levels was 21.9 month (p = 0.123). Induction of CUGBP2 expression by curcumin resulted in the downregulation of HO-1 and COX-2 and strongly sensitized tumor cells to GEM treatment. However, CUGBP2 silencing upregulated HO-1 and COX-2 protein expression and had a high effect on cells viability.

conclusionDecreased activity of CUGBP2 could be associated with high chemoresistance and early dissemination of pancreatic cancer through the HO-1- and COX-2-mediated cytoprotective and carcinogenesis pathways. Curcumin significantly increased the effectiveness of GEM treatment in vitro via the CUGBP2-mediated post-transcriptional regulation pathway.
