Basis for the Discrimination of Supercoil Handedness During DNA Cleavage by Human and Bacterial Type II Topoisomerases

, 2023
Type II topoisomerases are essential enzymes that regulate the topological state of DNA. These enzymes function by performing a double-stranded DNA passage reaction, the process of which generates a covalent enzyme-cleaved DNA complex (i.e., cleavage ...

A Bacterial Chromosome Structuring Protein Binds Overtwisted DNA to Stimulate Type II Topoisomerases and Enable DNA Replication

, 2020
When DNA is unwound during replication, it becomes overtwisted and forms positive supercoils in front of the translocating DNA polymerase. Unless removed or dissipated, this superhelical tension can impede replication elongation.

Development and analytical validation of a targeted short‐read next generation sequencing‐based pharmacogenetic panel for comprehensive variant detection

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Genomic profiling of patients for genetic variants that modify the effect of specific medications has many benefits, including the possibility of avoiding toxicities and ensuring an adequate effect of the medication. Our intention was to develop a comprehensive, high‐quality pharmacogenetic test panel for clinical use ...

Abstract 1688: Effect of Gefitinib on the reactions of mammalian type I and type II DNA topoisomerases

, 2010
Developing small molecule inhibitors in anti-cancer drug research is an integral part of clinical oncology. Gefitinib (Iressa) is a promising small molecule inhibitor of epidermal growth factor receptor (EGFR) tyrosine kinase.

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Clonal Hematopoiesis and CAR T Cell Therapy: From Biological Crosstalk to Clinical Implications

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Clonal hematopoiesis (CH) is increasingly recognized as a significant biological phenomenon in aging and cancer, marked by the expansion of hematopoietic stem and progenitor cells harboring somatic mutations in genes associated with myeloid neoplasms.

DNA topology: Topoisomerases keep it simple

, 1997
The ability of type II DNA topoisomerases to perturb the equilibrium distributions of DNA topoisomers is a consequence of their ability to hydrolyse ATP.

3-O-Methylfunicone, a Selective Inhibitor of Mammalian Y-Family DNA Polymerases from an Australian Sea Salt Fungal Strain

Marine Drugs, 2009
We isolated a pol inhibitor from the cultured mycelia extract of a fungal strain isolated from natural salt from a sea salt pan in Australia, which was identified as 3-O-methylfunicone by spectroscopic analyses.

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.
