DNA Topoisomerases and Their Poisoning by Anticancer and Antibacterial Drugs [PDF]

, 2010
DNA topoisomerases are the targets of important anticancer and antibacterial drugs. Camptothecins and novel noncamptothecins in clinical development (indenoisoquinolines and ARC-111) target eukaryotic type IB topoisomerases (Top1), whereas human type IIA

Unveiling the Taxonomic Diversity and Unprecedented Biosynthetic Treasure of the Phylum Myxococcota

Advanced Science, EarlyView.
Natural products remain vital sources of therapeutics, and the phylum Myxococcota constitutes an especially rich reservoir for them. Based on decades of microbiological efforts, we present 154 new Myxococcota genomes and revise taxonomy quadrupling the number of families and genera.

Epigenetic Reactivation of TNFRSF19 Suppresses Mitophagy and Sensitizes Triple‐Negative Breast Cancer to Doxorubicin

Advanced Science, EarlyView.
TNFRSF19 is an epigenetically silenced regulator of mitophagy in triple‐negative breast cancer. TNFRSF19 deficiency activates the TGFBR1–SMAD3–PINK1 axis to promote mitophagy and confer doxorubicin resistance, whereas decitabine‐mediated restoration of TNFRSF19 suppresses mitophagy and enhances doxorubicin sensitivity, revealing a targetable epigenetic–

Application of a novel microtitre plate-based assay for the discovery of new inhibitors of DNA gyrase and DNA topoisomerase VI.

PLoS ONE, 2013
DNA topoisomerases are highly exploited targets for antimicrobial drugs. The spread of antibiotic resistance represents a significant threat to public health and necessitates the discovery of inhibitors that target topoisomerases in novel ways.

A role for topoisomerase II alpha in chromosome damage in human cell lines [PDF]

, 2010
Human response to ionising radiation (IR) shows a wide variation. This is most clearly seen in the radiation-response of cells as measured by frequencies of chromosomal aberrations.

Structural insights into the DNA topoisomerase II of the African swine fever virus

Nature Communications
Type II topoisomerases are ubiquitous enzymes that play a pivotal role in modulating the topological configuration of double-stranded DNA. These topoisomerases are required for DNA metabolism and have been extensively studied in both prokaryotic and ...

Structural insights into the gating of DNA passage by the topoisomerase II DNA-gate

Nature Communications, 2018
Type II DNA topoisomerases (Top2s) direct the passage of one DNA duplex through another, which is important for resolving DNA entanglements. Here the authors combine X-ray crystallography and MD simulations and present the structure of the human Top2 DNA-

Integrating One Health to Mitigate the Emergence and Spread of Antimicrobial Resistance in Livestock and Aquaculture

Animal Research and One Health, EarlyView.
Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...

Can DNA Topoisomerases Be Ribonucleases? [PDF]

Cell, 1997
DNA topoisomerases catalyze changes in the linkage of DNA strands through a concerted mechanism of DNA strand cleavage and ligation reactions (for review, seeWang 1996xWang, J.C. Annu. Rev. Biochem. 1996; 65: 635–692Crossref | PubMedSee all ReferencesWang 1996).
