Artemisinin Derivatives Target Topoisomerase 1 and Cause DNA Damage in Silico and in Vitro

Frontiers in Pharmacology, 2017
DNA topoisomerases 1 and 2 are enzymes that maintain DNA topology and play important essential genome functions, including DNA replication and transcription.

New Insights into the Geometry and Topology of DNA Replication Intermediates

Biology
The regulation of superhelical stress, mediated by the combined action of topoisomerases and fork rotation, is crucial for DNA replication. The conformational changes during DNA replication are still experimentally challenging, mainly due to the rapid ...

MYC modulates TOP2A diffusion to promote substrate detection and activity

Nature Communications
Topoisomerases alleviate DNA supercoiling by cleaving and resealing DNA strands. Previously, we showed that the oncoprotein MYC recruits and stimulates topoisomerases to remove DNA entanglements generated by oncogenic transcription.

Condensin and topoisomerases cooperate to relieve topological stress at stalled replication forks

Nature Communications
Resolving complex topological structures at replication forks is essential for faithful DNA replication, yet the underlying mechanisms remain poorly understood.

Kinetoplast DNA: A Promising Drug Target for Treatment of Leishmaniasis

Journal of Mazandaran University of Medical Sciences, 2020
Leishmaniasis is a vector-borne zoonotic disease caused by various species of the genus Leishmania, (trypanosomatidae family) that is transmitted by phlebotomine sandflies.

Role of Supercoiling and Topoisomerases in DNA Knotting

DNA
DNA knots are deleterious for living cells if not removed. Several theoretical and simulation approaches address the question of how topoisomerases select the intermolecular passages that preferentially lead to unknotting rather than to the knotting of ...
