Topoisomerase II and tubulin inhibitors both induce the formation of apoptotic topoisomerase I cleavage complexes.
Topoisomerase I (Top1) is a ubiquitous enzyme that removes DNA supercoiling generated during transcription and replication. Top1 can be trapped on DNA as cleavage complexes by the anticancer drugs referred to as Top1 inhibitors as well as by alterations of the DNA structure. We reported recently that Top1 cleavage complexes (Top1cc) are trapped during apoptosis induced by arsenic trioxide and s...
متن کاملTopoisomerase Inhibitors and Types of Them
Objective: In this paper, we have introduced topoisomerase inhibitors, mechanism of action and types of them. DNA topoisomerases are ubiquitous enzymes that catalyze essential enzymes to solve the topological problems accompanying key nuclear processes such as DNA replication, transcription, repair and chromatin assembly by introducing temporary single or double strand breaks in the DNA. Result...

متن کاملTopoisomerase I Inhibitors.
Topoisomerase I inhibitors are a new class of anticancer agents with a mechanism of action aimed at interrupting DNA replication in cancer cells, the result of which is cell death. Most if not all Topoisomerase I inhibitors are derivatives of the plant extract camptothecin. Irinotecan (CPT-11), a semi-synthetic derivative of camptothecin, is approved in the United States for the treatment of co...
متن کاملTopoisomerase 1 cleavage complexes and tumorigenesis
Germline mutations in SPRTN cause Ruijs–Aalfs syndrome (RJALS), a disorder characterized by genome instability, progeria and early onset hepatocellular carcinoma. Spartan, the protein encoded by SPRTN, is a nuclear metalloprotease that is involved in the repair of DNA–protein crosslinks (DPCs). Although Sprtn hypomorphic mice recapitulate key progeroid phenotypes of RJALS, whether this model ex...
