Abstract:
To explore the methods of inducing apoptosis in human bladder cancer multidrug resistance cells. Methods: Expression of Fas antigen was detected with immunocytochemistry on BIU-87/ADM cells, and the effect of anti-APO-1 antibody was examined with in situ DNA terminal deoxynucleotydyl transferase assay (TDT),phase-contrast and electron microscope techniques. Results: We found that Fas antigen was highly expressed on BIU-87/ADM cell surface, and after treatment with anti-APO-1 antibody, survival rate of BIU-87/ADM cells was decreased, apoptotic morphological changes and TDT positive cells were found. Conclusion: These results suggested that anti-APO-1 antibody could induce apoptosis of BIU-87/ADM cells by combining Fas antigen.
