Downregulation of desmoglein 2 promotes EMT progression in gallbladder cancer.
Article in Histology and histopathology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo explore the correlation between the expression level of Desmoglein 2 (DSG2) and the epithelial-mesenchymal transition (EMT) progression in gallbladder cancer (GBC).
method106 GBC tissue specimens and corresponding clinical information were collected to make a tissue microarray. Immunohistochemical method was used to test the expression level of DSG2 in GBC tissues. DSG2 was knocked down in the GBC cell line GBC-SD to detect the change of its invasion and metastasis ability. Then RT-qPCR and Western Blot were applied on the DSG2-knocked down GBC-SD cells to detect the expression level change of genes associated with EMT.
resultThe high expression rate of DSG2 was significantly correlated with the N, M and TNM staging of patients (P<0.05). Survival analysis identified that GBC patients with high DSG2 expression level had significantly better survival (P<0.05). To further investigate the potential mechanism of DSG2 on regulating GBC tumor progression, we used knockdown DSG2 on GBC-SD cell lines. The results showed that GBC-SD cell lines with DSG2 knockdown showed a promotion of cell invasion and metastatic ability. The mRNA levels of EMT-related genes E-Cadherin, Snail, Twist, ZEB1, and β-catenin, which is a key protein in the Wnt signaling pathway, were also significantly altered. Besides, protein levels of E-cadherin and Snail showed consistent results.
conclusionThe downregulation of DSG2 in gallbladder cancer is hypothesized to be associated with the invasion and metastasis progression of gallbladder cancer cells by regulating EMT-related pathways. Its expression level can be a novel biomarker for gallbladder cancer, providing new perspectives for diagnosis and treatment strategies.
