Abstract:
The expression of survivin, a member of inhibitor of apoptosis (IAP) family, was examined in bladder transitional cell cancer (BTCC) tissue and adjacent normal tissues to examine its clinical implication in the development of BTCC. Thirty specimens of bladder cancer were detected for the expression of survivin by using immunohistochemistry and real-time quantitative reverse transcription polymerase chain reaction (RT-QPCR) in BTCC tissue and adjacent normal tissues. Our results showed that the positive rate of survivin immunostaining specimen were 0 and 60% (18/30) in the adjacent normal tissues, bladder cancer, respectively. The - △△ CT value of survivin in bladder cancer tissue was 10.2829 (9.0034-11.5624) times that in the adjacent normal tissues. The expressions of survivin were correlated with the pathological grades of tumor and clinical stages. It is concluded that there was only weak expression of survivin mRNA in the adjacent normal tissues, but the expression of survivin mRNA in bladder cancer tissue was much higher than that in the adjacent normal tissues and the expression of survivin was correlated with pathological grades and clinical stages of tumor.
