Abstract:
Endometrial carcinoma (EC) defines a heterogeneous group of neoplastic diseases originating from the transformation of endometrial cells that constitute the internal lining of the uterus. To date several molecular targets have been analysed to describe the natural course of the disease, claudins being among these. Claudins are the main components of tight junctions (TJs), and their main functions are ascribed to the compartmentalization of tissues and cell-cell communication by means of intracellular ions diffusion: these features are typical of epithelial cells. Their overexpression, mis-localization or loss contribute to the malignancy of EC cells. This review collected all available data regarding the expression, regulation and claudin-related signaling pathways to provide a comprehensive view on the influence of claudin in EC progression. Further, the translational potential of claudin differential expression was explored, indicating that their role in personalized medicine could also contribute to EC therapy besides their employment for diagnosis and prognosis.
Insights
Claudins, key proteins in endometrial carcinoma (EC), influence disease progression. Understanding their expression and signaling pathways offers potential for EC diagnosis, prognosis, and personalized therapy.
Area of Science:
- Oncology
- Cell Biology
- Molecular Biology
Background:
- Endometrial carcinoma (EC) is a heterogeneous uterine cancer.
- Claudins are crucial tight junction proteins in epithelial cells.
- Aberrant claudin expression is linked to EC malignancy.
Purpose of the Study:
- To comprehensively review claudin expression, regulation, and signaling in EC.
- To explore the translational potential of claudins in EC management.
Main Methods:
- Systematic literature review of claudin research in EC.
- Analysis of claudin expression, localization, and pathway involvement.
- Evaluation of claudins for diagnostic, prognostic, and therapeutic applications.
Main Results:
- Claudin alterations (overexpression, mis-localization, loss) are implicated in EC progression.
- Specific claudin patterns correlate with EC malignancy.
- Claudin signaling pathways are actively involved in EC pathogenesis.
Conclusions:
- Claudins are significant molecular targets in endometrial carcinoma.
- Differential claudin expression holds promise for EC diagnosis and prognosis.
