Overexpression of EMT-related transcription factors SNAI1 and ZEB1 is associated with more aggressive clinicopathological features of pancreatic cancer.

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.
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
BACKGROUND/
objectivesPancreatic ductal adenocarcinoma (PDAC) is one of the most fatal malignancies due to its aggressive nature and resistance to therapy. The epithelial-mesenchymal transition (EMT) drives cancer progression, regulated by transcription factors (TFs) such as SNAI1, SNAI2, ZEB1, ZEB2, and TWIST. This study evaluates EMT-TF expression in PDAC and its clinical relevance.
methodsPDAC tissues from 45 patients were analyzed using qRT-PCR and Western blot. Clinical features and survival outcomes were statistically examined for correlations with EMT-TF levels.
resultsmRNA levels of SNAI1 (16.4-fold, p = 0.02), SNAI2 (21.8-fold, p = 0.028), ZEB1 (17.2-fold, p = 0.037) were significantly elevated in PDAC tissues compared to healthy controls. TWIST showed 3.75-fold increase in PDAC tissue; however, this elevation was not significant (p = 0.124). Corresponding protein-level increases were observed for Snail1/Slug and Zeb1. High SNAI1 expression correlated with peripancreatic invasion (p = 0.026) while ZEB1 overexpression was significantly associated with shorter survival (15.2 vs. 33.3 months, p = 0.037) and remained an independent prognostic factor in multivariate analysis. ZEB2 mRNA was reduced, however, protein levels were elevated. TWIST mRNA overexpression was not reflected at the protein level.
conclusionsOverexpression of EMT transcription factors SNAI1 and ZEB1 reflect more aggressive histopathological patterns of PDAC. The strong correlation of SNAI1 expression with the expression of other EMT-TFs highlights its' role in peripancreatic invasion, as well as impact on overall survival and may serve as an argument defining the leading role of SNAI1 in this context.
