Telomerase Inhibition and Chemosensitization of Prostate Cancer Cells

Abstract

We hypothesize that telomerase inhibition (telomere shortening) can sensitize human tumor cells to existing anticancer drugs. During the period of the grant we made the following findings-: 1) 2'-methoxy ethyl oligonucleotides inhibit - -telomerase in prostate cancer cells, cause telomeres to shorten, and cause cell- proliferation to decrease; -2) Cell proliferation in culture is -more pronounced when cells are grown under conditions that mimic tumor growth; 3) Cell proliferation is dramatically reduced in a xenograft model using LNCAP cells, and 4) We did not observe significant synergy with standard chemotherapy agents. The ability of relatively short-term treatments with telomerase inhibitors to slow tumor growth in vivo suggests that telomerase inhibitors are a reasonable approach to prostate cancer therapy.
