Abstract:
Objective To study clusterin expression in bladder cancer cell line EJ and its antiapoptosis mechanism. Methods The expression of clusterin in EJ cells was detected by means of immunocytochemical staining and its effect on apoptosis studied by 3′TUNEL method. Results Clusterin expressed clearly in EJ cells.Likewise,when a small dose of clusterin was added,clusterin was stained strongly in the cytoplasm of the EJ cells and MMC induced apoptosis of the EJ cells was markedly inhibited. Conclusions Clusterin can penetrate the cell membrane getting into the cell cytoplasm and there in the cytoplasm the antiapoptosis effect is evoked.By detecting the clusterin expression,recurrence and multidrug resistance of a bladder cancer may be evaluated.It is hopeful that the use of clusterin antibody in the treatment of bladder cancer might be feasible.
