[Expression of special AT-rich sequence-binding protein in bladder urothelial carcinoma and its clinical significance].
OBJECTIVE
To detect the expression of special AT-rich sequence-binding protein (SATB1) in bladder urothelial carcinoma and investigate its correlation to the biological behavior of the carcinoma.


METHODS
The expression of SATB1 mRNA was detected in 34 cases of bladder urothelial carcinoma and 14 normal bladder tissues by RT-PCR, and the protein expression of SATB1 was detected in 68 cases of bladder urothelial carcinoma and 17 normal bladder tissues by immunohistochemistry. The correlation between SATB1 expressions and the biological behavior of the tumor was analyzed.


RESULTS
The expression of SATB1 was significantly higher in bladder urothelial carcinoma tissues than in normal bladder tissues (P<0.05). and the expression of SATB1 in the tumor tissues was correlated to the clinical stage and metastasis of the tumor.


CONCLUSIONS
SATB1 expression can be associated with the development and metastasis of bladder urothelial carcinoma and may potentially serve as an indicator for predicting the prognosis of bladder urothelial carcinoma.
