Abstract excerpt

Glioblastomas are widely characterised by the mutation of the p53 gene and p53 disruption sensitizes glioblastoma cells to DNA topoisomerase I (TOPO I) inhibitor-mediated apoptosis. We investigated the effects of combined treatments with the DNA topoisomerase I inhibitor Topotecan and the poly(ADPR)polymerase-1 inhibitor NU1025 in D54(p53wt) and U251(p53mut) glioblastoma cell lines. Analysis of cell growth and...
