Covalent modification of cytosine nucleotides within the genome encode essential epigenetic information, with methylation (5meC) and hydroxymethylation (5hmC) having received most attention.

UV irradiation induces two major types of pyrimidine dimers, CPDs and 6–4PPs. Whereas 6–4PPs efficiently induce cell‐cycle arrest, CPDs do not and frequently persist into S phase. As a result, DSBs can arise in the presence of unrepaired CPDs after 6–4PPs have been repaired, increasing the risk of genomic instability.

Mechanisms of Thrombocytosis in Iron‐Deficiency Anemia
ABSTRACT Iron‐deficiency anemia is frequently accompanied by reactive thrombocytosis, yet the mechanisms underlying this association remain incompletely understood. Beyond impaired erythropoiesis, iron availability has emerged as an active regulator of hematopoietic lineage decisions.

The epigenetic landscape of skeletal muscle in response to exercise and aging
Epigenetic mechanisms regulate gene expression in response to exercise and aging, thereby supporting skeletal muscle plasticity. Acute exercise induces chromatin remodeling through histone modifications and DNA methylation, promoting the expression of exercise‐responsive genes.

Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis
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.

Periodontal Medicine Rewired: Mechanisms Linking Periodontitis to Systemic Diseases
This review reorganizes decades of research in periodontal medicine into a multi‐dimensional framework, illustrating how periodontitis influences systemic health through at least seven interconnected mechanisms. ABSTRACT Periodontitis is now recognized not merely as a localized oral condition but as a systemic disease linked to over 70 communicable and

The modification and recognition of 5‐methylcytosine (m5C) are involved in the initiation and progression of various tumor types. However, the precise role and potential mechanism of Y‐box‐binding protein 1 (YBX1) in esophageal squamous cell carcinoma ...

Osteoporosis and Periodontitis: Two‐Way Epidemiological and Mechanistic Evidence
This review investigates the main mechanistic pathways connecting local periodontitis to systemic osteoporosis. Seven interconnected mechanisms are identified. ABSTRACT Osteoporosis and periodontitis are highly prevalent, chronic inflammatory diseases that constitute a major global health burden.
