“Ubiquitin-Mediated Proteolysis and Cell Sensitivity to Camptothecin”

Hervé Jacquiau, J.D., Ph.D., M.Sc., D.E.A.

Hervé Jacquiau, Ph.D. co-authored this article discussing Camptothecin (CPT) stabilizes a covalent DNA topoisomerase I (Top1 p)-DNA complex that is converted into irreversible lesions in S-phase and induces cell death. To define cellular processes that recognize and repair CPT-induced lesions, a yeast genetic screen to isolate mutants with enhanced sensitivity to Top1p poisons at 35°C was developed.
