RNA topoisomerase is prevalent in all domains of life and associates with polyribosomes in animals [PDF]
, 2016 DNA Topoisomerases are essential to resolve topological problems during DNA metabolism in all species. However, the prevalence and function of RNA topoisomerases remain uncertain.

Studying DNA Double-Strand Break Repair: An Ever-Growing Toolbox [PDF]
, 2020 To ward off against the catastrophic consequences of persistent DNA double-strand breaks (DSBs), eukaryotic cells have developed a set of complex signaling networks that detect these DNA lesions, orchestrate cell cycle checkpoints and ultimately lead to ...

Advanced Science, EarlyView.Homoisoflavanone (HIF), a bioactive compound isolated from Polygonatum kingianum, selectively suppresses colorectal cancer progression by inducing DNA damage‐mediated mitochondrial apoptosis and parthanatos‐like cell death. HIF triggers mitochondrial dysfunction, including depolarized membrane potential, elevated ROS, and ATP depletion, while impairing

MRE11 function in response to topoisomerase poisons is independent of its function in double-strand break repair in Saccharomyces cerevisiae. [PDF]
PLoS ONE, 2010 Camptothecin (CPT) and etoposide (ETP) trap topoisomerase-DNA covalent intermediates, resulting in formation of DNA damage that can be cytotoxic if unrepaired.

Advanced Science, EarlyView.A mechanically tunable ECM platform is created by integrating dECM–alginate matrices with in‐bath tumor printing. The mechanically tunable ECM environment drives tumors to acquire hypoxia, mechanotransduction signaling, metastatic traits, and drug‐resistant phenotypes that collectively promote malignant transformation.

In Vitro Action of Flavonoids in the Canine Malignant Histiocytic Cell Line DH82
Molecules, 2013 Cancer is commonly diagnosed in dogs over the age of 10 and is a leading cause of death due to the lack of effective drugs. Flavonoids possess antioxidant, anti-inflammatory and anticarcinogenic properties and have been studied as chemopreventive agents ...

Transcription facilitated genome-wide recruitment of topoisomerase I and DNA gyrase. [PDF]
PLoS Genetics, 2017 Movement of the transcription machinery along a template alters DNA topology resulting in the accumulation of supercoils in DNA. The positive supercoils generated ahead of transcribing RNA polymerase (RNAP) and the negative supercoils accumulating behind

Reconstitution of recombination-associated DNA synthesis with human proteins. [PDF]
, 2013 The repair of DNA breaks by homologous recombination is a high-fidelity process, necessary for the maintenance of genome integrity. Thus, DNA synthesis associated with recombinational repair must be largely error-free.
