ABSTRACT
Objective To investigate the expression of 14-3-3ε protein in the bladder urothelial carcinoma (BUC) and to explore its association with the clinicopathologic features.Methods The bladder urothelial carcinoma samples were divided into three groupsnormal control group of 10 cases,low-grade malignant BUC group of 25cases (includes 5 cases of papilloma,10 cases of PUNLMP and 10 cases of low grade non-invasive papillary urothelial carcinoma),high-grade malignant BUC group of 21 cases (includes 11 cases of high-grade non invasive papillary urothelial carcinoma and 10cases of infiltrating carcinoma).The expression and location of 14-3-3ε in three groups were detected by immunohistochemical EnVision and the relationship with clinicopathologic parameters was analyzed.Results 14-3-3ε expression was observed in the cytoplasm of the cell.The expression of 14-3-3ε in normal control group was 90 % (9/10),low-grade malignant BUC group was 72.0 % (18/25),high grade malignant BUC group was 14.3 % (3/21).It correlated with histological grading but had not showed correlation with other clinicopathologic parameters.There was significant difference in 14-3-3ε expression between the high grade malignant BUC group and the low-grade malignant BUC group,the high grade malignant BUC group and norml control group (all P < 0.05).Conclusions 14-3-3ε plays an important role in carcinogenesis of BUC.It may be a biomarker for early diagnosis and classification of BUC and shows promise for clinic application.
