DEK蛋白在膀胱尿路上皮癌癌组织和尿液中的表达及临床意义
Expression of DEK Protein in the Tissue and Voided Urine of Patients with Bladder Urothelial Carcinoma and Its Clinical Significance
摘要
Abstract
Objective To detect the presence of DEK protein in the tissue and voided urine of patients with bladder urothelial carcinoma ,and an⁃alyze the relationship between DEK protein and clinical pathological classification of bladder cancer. Methods The expression of DEK protein was examined by immunohistochemistry in 48 bladder cancer tissues and 18 adjacent normal tissues(control group). The presence of DEK protein in voided urine was analyzed by western blot in 28 bladder cancer patients and 6 healthy individuals(control group). Results The positive ex⁃pression of DEK protein in bladder tumor tissues(73%)is higher than in adjacent normal tissues(33%,P<0.05). The expression of DEK in su⁃perficial bladder cancer(86%)was found higher than invasive bladder cancer(55%)with significant differences(P<0.05). The expression of DEK in urine samples of bladder cancer patients(0.834)was found higher than control group(0.242,P<0.05);Compared with the DEK expres⁃sion of control group,the sensitivity of diagnosis of bladder cancer with voided urine could be 82.1%. Conclusion DEK protein positive ex⁃pressed in tissues and voided urine of patients with bladder urothelial carcinoma. The expression was correlated with pathological classification of bladder cancer. The positive rate of DEK expression in early stage of tumor tissues is higher than late stage. The presence of DEK protein in tissues and voided urine can be considered as a suitable biomarker for bladder cancer potentially.关键词
