Objective:
To investigate the expression of EMS1 and DcR3 in laryngeal carcinoma and analyze the relation of EMS1 and DcR3.
Method:
The expression of EMS1 and DcR3 protein in 41 laryngeal carcinoma fresh samples and 41 para-carcinoma tissues (to cutting margin > 0.5 cm) were measured by flow cytometry, and 15 normal laryngeal mucosa samples were also studied as controls.
Result:
(1) The quantitative and qualitative expression of EMS1 and DcR3 protein in laryngeal carcinoma tissues was obviously higher than those in para-carcinoma and in normal laryngeal mucosa tissues respectively (P < 0.05). There was no significant difference between the expression of para-carcinoma and normal laryngeal mucosa tissues. (2) In laryngeal carcinoma, the expression of EMS1 and DcR3 protein was independent of patients' clinical classification, tumor size, smoking history, patients' age and sex but associated with tumor metastasis, pathological grade and clinical stage. (3) In laryngeal carcinoma, the expression of EMS1 was positively correlated with that of DcR3.
Conclusion:
EMS1 was positively related to DcR3, which might play an important role in the carcinogenesis and development of laryngeal carcinoma by synergic effect.
