1 Topotecan-triggered degradation of topoisomerase I is p53-dependent and impacts cell survival. Topotecan tumor protein p53 Homo sapiens
2 Treatment of p53 wild-type cells with pifithrin-alpha, an inhibitor of the trans-activating activity of p53, caused reversal of the phenotype, making wild-type cells more sensitive to topotecan. Topotecan tumor protein p53 Homo sapiens
3 Treatment of p53 wild-type cells with pifithrin-alpha, an inhibitor of the trans-activating activity of p53, caused reversal of the phenotype, making wild-type cells more sensitive to topotecan. Topotecan tumor protein p53 Homo sapiens
4 U138 cells (p53 mutated) were significantly more sensitive to topotecan than U87 cells (p53 wild-type). Topotecan tumor protein p53 Homo sapiens
5 The data suggests that p53 causes resistance of cells to topo I inhibitors due to stimulation of topotecan-triggered topo I degradation which may impact topotecan-based cancer therapy. Topotecan tumor protein p53 Homo sapiens
6 The data suggests that p53 causes resistance of cells to topo I inhibitors due to stimulation of topotecan-triggered topo I degradation which may impact topotecan-based cancer therapy. Topotecan tumor protein p53 Homo sapiens
