Poly(ADP-ribosylation) of a DNA topoisomerase [PDF]
, 1983 journal articleA DNA topoisomerase activity, copurifying with poly(ADP-ribose) synthetase from calf thymus, >95% inhibited if extensive poly(ADP-ribosylation) is allowed to occur.

The FEBS Journal, EarlyView.Chromosomal DNA double‐strand breaks (DSBs) are repaired by homologous recombination and nonhomologous end joining (NHEJ). Recent work has additionally established theta‐mediated end‐joining (TMEJ) as a mechanism for DSB joining. Cells lacking NHEJ and TMEJ can repair DSBs in a homology‐dependent manner.

TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics
The FEBS Journal, EarlyView.This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...

Ploidy‐dependent modulation of DNA replication kinetics in Xenopus
The FEBS Journal, EarlyView.Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not

Mathematical models characterising the kinetics and dynamics of topotecan to account for drug resistance mechanisms [PDF]
This thesis describes the use of mathematical modelling in studying the kinetics and dynamics of the anti-cancer agent topotecan (TPT), a semi-synthetic derivative of the natural extract camptothecin (CPT), which has been found to act as an inhibitor ...

Internal Medicine Journal, EarlyView.Abstract Background and Aims Systemic sclerosis (scleroderma; SSc) patients can develop pulmonary arterial hypertension (PAH), which is a leading cause of death. We sought to evaluate severity, therapeutic strategy and survival of SSc‐PAH in the Australian Scleroderma Cohort Study (ASCS).

Journal of Fish Diseases, EarlyView.ABSTRACT Monitoring antimicrobial resistance (AMR) in fish pathogens is essential for supporting sustainable aquaculture. In this study, susceptibility testing and genome sequencing were used to characterize the AMR profile of seven Flavobacterium psychrophilum originating from Danish rainbow trout farms (2019–2022).

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.

Antibiotic‐mediated immune modulation in periodontitis
Periodontology 2000, EarlyView.Abstract Periodontitis is a chronic inflammatory disease affecting the supporting structures of the teeth. Although initiated by dysbiotic microbial communities, its progression is largely driven by the host's uncontrolled inflammatory response. While antibiotics have conventionally been employed in periodontitis therapy for their antimicrobial ...
