E-cadherin expression in the tongue epithelium of streptozotocin-induced diabetic rats: an exploratory study.

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
objectiveLittle was found on the association between diabetes and its effect on epithelial intercellular adhesion. However, no study reported the association between hyperglycemia and E-cadherin-mediated cell adhesion in tongue epithelium. This study aimed to explore the potential impacts of hyperglycemia on the epithelial E-cadherin expression in the tongue's epithelial tissue in streptozotocin (STZ)-induced diabetic rats. MATERIAL AND
methodsTwelve male Wistar albino rats were randomly allocated into control and STZ-induced diabetic groups. At the 5-week post-STZ injection, rats were euthanized, and the tongues were harvested and preserved in formalin. Epithelial thickness was assessed using hematoxylin and eosin (H&E) staining, while immunohistochemistry (IHC) was employed to analyze the expression of E-cadherin. Statistical analysis was performed using unpaired t-tests and two-proportion Z-tests, with a significance level determined at p < 0.05.
resultsThe results showed a significant reduction in epithelial thickness in the dorsal tongue of STZ-diabetic rats compared to the control group (p = 0.0173). Additionally, E-cadherin expression in the dorsal tongue epithelium was markedly weaker in the diabetic group than in the control (p < 0.0001).
conclusionsThis exploratory study is the first to report that hyperglycemia reduces E-cadherin expression in the dorsal tongue epithelium, possibly contributing to oral epithelial alterations observed in diabetes. These findings not only highlight the potential diagnostic value of E-cadherin as a biomarker for oral complications in diabetic patients but also provide a foundation for future translational and clinical studies exploring therapeutic interventions targeting epithelial integrity in diabetes.
