Biomarker: E-cadherin

Histology type: endometrial carcinoma

Country: China

Region: Tianjin

Study type: retrospective study

Followed up time :

Subgroup 1 name : E-Cadherin Expression Reduced/Lack

Subgroup 1 number: 42

Subgroup 2 name: E-Cadherin Expression Positive

Subgroup 2 number: 40

Conclusion: We found that the hypermethylation of CDH1 promoter, which caused low expression of E-cadherin in endometrial cancer, was associated with not only clinicopathological progress of endometrial cancer but also with the overall 5-year clinical survival rate. The findings provide the potential prognostic target molecule for patients with endomethrial cancer.

Sample type : tissue

Sample method: immunohistochemistry/Methylation-specific PCR (MSP)

Expression pattern : expression(<10%)

Expression elevation: E-cadherin expression was classified as low when 10–90% of cancer cells stained positive, and tumors with <10% E-cadherin positivity were considered Ecadherin negative

Funtion Uniprot: Cadherins are calcium-dependent cell adhesion proteins (PubMed:11976333). They preferentially interact with themselves in a homophilic manner in connecting cells; cadherins may thus contribute to the sorting of heterogeneous cell types. CDH1 is involved in mechanisms regulating cell-cell adhesions, mobility and proliferation of epithelial cells (PubMed:11976333). Has a potent invasive suppressor role. It is a ligand for integrin alpha-E/beta-72 Publications E-Cad/CTF2 promotes non-amyloidogenic degradation of Abeta precursors. Has a strong inhibitory effect on APP C99 and C83 production.1 Publication (Microbial infection) Serves as a receptor for Listeria monocytogenes; internalin A (InlA) binds to this protein and promotes uptake of the bacteria.3 Publications
