The role of extracellular vesicles in cell–cell crosstalk in cardiotoxicity

The Journal of Physiology, EarlyView.
Abstract figure legend Administration of a pharmacological agent can result in off‐target cardiotoxicity which can be driven by cell–cell crosstalk between healthy and dysfunctional cardiac cells. Extracellular vesicles (EVs) are lipid bilayer structures that can move biological cargo between cells, facilitating cell–cell crosstalk.

Inhibition of topoisomerase 2 catalytic activity impacts the integrity of heterochromatin and repetitive DNA and leads to interlinks between clustered repeats

Nature Communications
DNA replication and transcription generate DNA supercoiling, which can cause topological stress and intertwining of daughter chromatin fibers, posing challenges to the completion of DNA replication and chromosome segregation.

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Topological origins of chromosomal territories [PDF]

, 2017
Using freely jointed polymer model we compare equilibrium properties of crowded polymer chains whose segments are either permeable or not permeable for other segments to pass through.

Human‐derived cardiac‐neural microtissues reveal catecholaminergic polymorphic ventricular tachycardia is also a disease of the sympathetic neuron

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...

Synergistic Effects of IMP‐1700, Ciprofloxacin, and X‐Ray Radiation in Bacteria and Mammalian Cell Lines: Implications for Use in Antimicrobial‐Resistant Bacteria

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
IMP‐1700 enhances the cytotoxic effect on bacteria in combination with either ciprofloxacin (CPX) or X‐ray. In noncancerous and tumor cells, combination treatments markedly reduce viability with radiosensitizing effects. Further studies are needed to clarify the mechanism underlying IMP‐1700s effects on mammalian cells. Created in BioRender. Kjaer, A. (
