DNA topoisomerases play an important role in regulating DNA structure, thus affecting many aspects of chromosome function inside cells. Recent progress in this field raises exciting questions regarding the distinct and critical functions of multiple topoisomerases, and the roles of DNA topoisomerases in the processes of chromosome condensation ...

Topoisomerases and Carcinogenesis: Topoisomerase IIIα and BLM
2011In human cells, Topoisomerase IIIα (Top3α) is the main partner of BLM, the Bloom syndrome (BS) helicase. BS constitutes a genetic and clinical model for recessive cancer predisposition and study of this disease may help to decipher pathways of carcinogenesis in the general population.

AbstractTopoisomerases are nuclear enzymes that play essential roles in DNA replication, transcription, chromosome segregation, and recombination. All cells have two major forms of topoisomerases: the type I enzymes, which make single‐stranded cuts in DNA, and the type II enzymes, which cut and pass double‐stranded DNA.

This chapter discusses single-molecule approaches in the study of topoisomerases. After introducing the problem posed by DNA entanglement, it describes type I and type II topoisomerases, which solve that issue. Single-molecule assays have nailed down the different mechanisms of bacterial and eukaryotic type I topoisomerases.

DNA topoisomerases and topoisomerase inhibitors.
Pathologie-biologie, 1995DNA topoisomerases are ubiquitous nuclear enzymes, essential for several steps of DNA metabolism. They have recently been shown to be specific targets of a number of anticancer agents. In this review are discussed the most recent discoveries in the physiology and the molecular biology of DNA topoisomerases, and the mechanism of interaction with drugs ...
