Telomerase activity, Myc and Bcl-2: possible indicators of effective therapy of prostate cancer with 9-nitrocamptothecin.
2000
In this report, we demonstrate the down-regulation of telomerase activity and c-Myc and Bcl-2 expression during 9-nitrocamptothecin (9NC)-induced regression of human DU145 prostate tumors grown as xenografts in immunodeficient mice. These changes were not observed in tumors generated by DU145-derived cells resistant to 9NC. We suggest that telomerase activity, c-Myc and Bcl-2 can collectively serve as molecular diagnostic indicators of the effectiveness of 9NC during treatment of human prostate tumors.
