ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

open access: yesJournal 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

open access: yesPeriodontology 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 ...

Expression of Topoisomerase II Alpha in Canine Colorectal Polyps, Adenomas and Adenocarcinomas

open access: yesVeterinary and Comparative Oncology, EarlyView.
ABSTRACT With the development and increased accessibility of diagnostic methods in veterinary medicine, the possibilities for early detection of proliferative lesions in the canine large intestine have expanded over the past decade. Since in human medicine, topoisomerase II alpha (Topo IIα) is considered a prognostic and predictive marker in various ...

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

open access: yesThe 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.

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

open access: yesThe 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.

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

open access: yesThe 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 ...

Infant Embryonal CNS Tumors: Molecular Insights and Treatment Considerations for Contemporary Pediatric Neuro‐Oncology

open access: yesPediatric Blood &Cancer, Volume 73, Issue 11, November 2026.
ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...
