RAD51C-XRCC3 complex regulates FANCM-mediated R-loop resolution to safeguard genome integrity. (PubMed, Sci Adv)

The CX3 complex-mediated R-loop resolution is independent of its fork maintenance function. Collectively, we demonstrate a previously unidentified role of the CX3 complex in preventing R-loop-induced genome instability by regulating FANCM-mediated R-loop resolution.

Integrated case-control and in silico analysis of DNA double-strand break repair gene variants (RAD51, XRCC2, XRCC3, XRCC4, and LIG4) for ovarian cancer susceptibility. (PubMed, Gene)

Overall, RAD51 and LIG4 polymorphisms may contribute to OC susceptibility in South Indian women. Larger, multi-center studies are warranted to validate these findings and explore their potential as predictive biomarkers for OC.

Single Nucleotide Polymorphisms as Biomarkers of Response to Neoadjuvant Chemoradiotherapy in Rectal Cancer: A Systematic Review. (PubMed, Cancers (Basel))

Although XRCC1 and MTHFR polymorphisms have been extensively studied, their predictive utility remains inconclusive. Future research should prioritize large, multicenter prospective studies with standardized treatment and outcome definitions, and consider polygenic risk models or integrated multi-omic approaches.

Cryo-electron microscopy visualization of RAD51 filament assembly and end-capping by XRCC3-RAD51C-RAD51D-XRCC2. (PubMed, Science)

The RAD51B complex promotes dynamic adenosine triphosphate hydrolysis-dependent assembly of RAD51 filaments, whereas the XRCC3 complex stably caps the 5'-termini of RAD51 filaments to promote homologous pairing, as visualized by cryo-electron microscopy. Highly conserved across evolution, these complexes reveal insights into RAD51 filament formation and capping during DNA repair and replication fork stabilization.

A comprehensive compilation of data on the association between XRCC3 polymorphisms and thyroid cancer susceptibility. (PubMed, BMC Endocr Disord)

XRCC3 rs1799794 polymorphism is associated with increased thyroid cancer risk, particularly under recessive genetic models. The rs1799796 variant may confer a protective effect in Asian populations, whereas rs861539 shows no significant association. These results highlight population-specific genetic effects and underscore the importance of considering ethnicity in genetic association studies. Further large, well-designed investigations are warranted to confirm these findings and to explore potential gene-environment interactions.

Genetic Variants Associated with Breast Cancer Are Detected by Whole-Exome Sequencing in Vietnamese Patients. (PubMed, Diagnostics (Basel))

This is the first WES study to identify BC-associated genetic variants in Vietnamese patients, providing a comprehensive database of BC susceptibility gene variants. We suggest using WES as a tool to identify genetic variants in BC patients for risk prediction and treatment guidance.

Expression analysis of C-FOS and XRCC3 Thr241Met polymorphism in gastric cancer. (PubMed, Cell Mol Biol (Noisy-le-grand))

We present in our findings that molecular profiling coupled with demographic profiling is highly relevant in risk assessment and early detection techniques in gastric cancer. The study contributes to the further comprehension of the molecular pathogenesis of gastric carcinogenesis and suggests C-FOS and XRCC3 as possible clinical and epidemiological markers.
