Abstract
Objective:To investigate expressions of Fra-1 in laryngeal squamous cell carcinoma. Method:Using immunohistochemical method and RT-PCR detecting 47 cases of laryngeal squamous carcinoma tissues and 21 cases of para-carcinoma tissues with the level of protein and mRNA, we analyzed the relationship of the genes expression and clinical parameters. Result:The level of protein positive expression of Fra-1 genes in laryngeal squamous cancer tissue were higher than adiacent tissues (P<0.05). The expression of Fra-1 protein in laryngeal squamous cancer tissue were significant correlation with the clinical stages, lymph metastasis, smoking. They had no significant correlation with the pathological grade, age, anatomic zonation. The mRNA level expression of Fra-1 genes in laryngeal squamous cancer tissue were higher than adjacent tissues (P<0.01). The expression of Fra-1 gene in the mRNA level was correlated with pathologic stage, clinical stage, lymph metastasis, and smoking, but wasn't correlated with age and anatomic zonation. Conclusion:In laryngeal squamous cell carcinoma, the expression of Fra-1 gene are overexpressed. Fra-1 may play a role in the occurrence and development of the laryngeal cancer.
