Cancer Therapy: Preclinical DNA Damage Persistence as Determinant of Tumor Sensitivity to the Combination of Topo I Inhibitors and Telomere-Targeting Agents
Purpose: We previously reported that the G-quadruplex (G4) ligand RHPS4 potentiates the antitumor activity of camptothecins both in vitro and in tumor xenografts. The present study aims at investigating the mechanisms involved in this specific drug interaction. Experimental Design: Combination index test was used to evaluate the interaction between G4 ligands and standard or novel Topo I inhibi...

متن کاملApoptosis as a Determinant of Tumor Sensitivity to Topotecan in Human Ovarian Tumors: Predinical in Vitro/in Vivo
In their paper on apoptosis and topotecan sensitivity, Casemi et a!. (1) highlight an important aspect of Topo I’ inhibitor effect on the cancer cell, i.e., its ability to undergo apoptosis following drug-target interaction. The antiproliferative activity of the Topo I inhibitors seems to be different from their apoptotic induction potential. Indeed, this difference may have significant bearing...
