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.

Molecular Links Between Heat Stress and DNA Damage Response in Plants
ABSTRACT Climate change poses a major threat to agricultural productivity and, consequently, to global food security. Among the consequences of climate change, heat stress (HS) has emerged as a critical factor limiting crop performance. This has stimulated extensive research over the past decade to elucidate the molecular and physiological mechanisms ...

RAD51 modulates in nasopharyngeal carcinoma cells by regulating Caspase-8-mediated pyroptosis
Objective Radiotherapy is a first-line treatment for nasopharyngeal carcinoma (NPC), but resistance to radiation remains a major clinical challenge. This study aimed to investigate the role of RAD51, a key homologous recombination repair protein, in ...

Translating whole‐genome doubling into precision medicine in cancer
Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)

RAD51 assembly on single-stranded DNAs is an important step in the homology-dependent repair of DNA damage. Here authors reveal a role for the human RAD51 paralogue, SWSAP1, as a regulator of RAD51 assembly, by antagonizing RAD51 remodeller, FIGNL1 AAA +

Integrative multi‐omics analysis delineates a mitochondrial–immune axis governing neoadjuvant chemotherapy response in high‐grade serous ovarian cancer. Immune‐active tumors exhibit enhanced B‐cell infiltration and favorable sensitivity, whereas metabolically rewired tumors display oxidative phosphorylation dependency and resistance.

ABSTRACT Fanconi Anemia (FA) is the most frequent inherited bone marrow failure syndrome. A role for the XRCC2 gene in FA was suspected in 2012 and confirmed in 2016, but only two affected individuals have been described thus far, and no long‐term follow‐up is available.
