Abstract:
Objective To study the correlation of NF-?B expression with the grade, the stage, the recurrence, the metastasis and PKC expression of bladder transitional cell carcinoma. Methods The expression of NF-?B and PKC was examined with SP immunohistochemical method in 54 cases of paraffin-embedded bladder transitional cell carcinomas tissues and 13 cases of normal bladder tissues. Results The positive expression rate of NF-?B P65 and PKC in bladder transitional cell carcinomas was 88 9% and 81 5% respectively. The expression rate of NF-?B decreased along with pathological grade and clinical stage increased, while its expression increased along with the rate of recurrence and metastasis elevated. There was a positive relationship between NF-?B and PKC expressions. Conclussion NF-?B may play a role at early stage of bladder transitional cell carcinoma. It probably serves as an index to evaluate the malignant extent and progression of bladder transitional cell carcinoma. PKC probably takes part in the activation process of NF-?B.
