摘要

Background: The sensitivity of non-S-phase cells to Top1-targeting drugs has been under-explored. Results: Quiescent Top2β-deficient cells are specifically hypersensitive to Top1-targeting drugs. Conclusion: Top2α deficiency promotes camptothecin-induced apoptosis as a result of RNA polymerase II depletion and p53 accumulation. Significance: This study has identified Top2α as a novel determinant for camptothecin sensitivity.
