1. Via interference with XRCC1/PARP1-mediated base excision repair.

2. we showed that CHK2-dependent phosphorylation of PARP1 not only regulates its cellular localization but also promotes its catalytic activity and its interaction with XRCC1. These findings indicate that CHK2 exerts a multifaceted impact on PARP1 in response to oxidative stress to facilitate DNA repair and to maintain cell survival.

3. Study shows that polymorphisms in the genes coding for the DNA damage repair enzymes - OGG1 Ser326Cys (rs1052133) and XRCC1 Arg399Gln (rs25487) - may be associated with poor sperm parameters and male infertility.

4. Data suggest that phosphorylation of T358 and T367 and p38 signaling are important for proper regulation of XRCC1 recruitment to DNA damage.

5. our study therefore identified a pathway in which DNA damage-induced poly(ADP-ribosyl)ation (PARylation) promotes SUMOylation of XRCC1, which leads to more efficient recruitment of POLB to complete base excision repair

6. Increased lung cancer risk was revealed in workers-carriers of homozygous minor genotype of genes OGG1] Ser326Cys (OR - 4.67, p = 0.007), APE1 Asp148Glu (OR = 1.82, p = 0.063) and XRCC1 Gln399Arg (OR = 2.86, p = 0.026).

7. Low XRCC1 rs25487 AA is associated with breast Cancer.

8. restriction fragment length polymorphism (RFLP) method was used for evaluating of XPD (-751), XRCC4 (-1394 and a variable number of tandem repeats in intron 3), and XRCC1 (-399) genes.We did not observe any noteworthy discrepancy in patients in the SH, CH, CAH, and NE groups in terms of XRCC1 (-399)

9. A statistically significant association between methylenetetrahydrofolate reductase (MTHFR) 677T/T, thymidylate synthase (TS) 5'-untranslated region (UTR) 3RG, TS 3'-UTR -6 bp/-6 bp, XRCC1 399G/G genotypes and short survival was found in patients receiving best supportive care (BSC)by multivariate analysis

10. The methylation status of XRCC1 (methylated at T0) and hOGG1 (unmethylated at T0) remained unchanged in the three sampling times. In conclusion, this study showed modulations of hOGG1 and XRCC1 expression especially 1 day after elective surgery in patients undergoing PROP and ISO anaesthesia

11. The TP53 codon 72 Arg allele and XRCC1 codon 399 Gln allele are likely to have a protective effect against lung adenocarcinoma, especially in individuals older than 50 years of age. XRCC1 and TP53 genotyping might be a useful low-cost tool for evaluating individual lung cancer risk.

12. Polymorphic variants of XRCC1 Arg399Gln and XPD Lys751Gln are not associated with the risk of gastric cancer in the Kashmiri population.

13. The effects of chronic smoking on oral mucosa led to the methylation of genes MRE11A PMS2, XRCC1 and MLH3, but resulted in a reduction of gene expression of MRE11A and PMS2, which showed >/=50% methylation. These results provide evidence that smoking cause methylation and reduced expression of repair genes.

14. T-77C and Arg399Gln polymorphisms of the XRCC1 gene, as well as the 186C>T and Val158Met polymorphisms of the COMT gene, increased the risk of lung cancer in non-smoking women.

15. XRCC1 Arg194Trp, Arg280His, and Arg399Gln did not affect overall survival after platinum-based chemotherapy in ovarian cancer patients. However, disease status could affect the relationship between Arg399Gln and overall survival in these patients

16. results suggested an increased risk for Non-Hodgkin Lymphoma regarding the XRCC1 Arg194Trp polymorphism in a Romania population, while XRCC1 Arg399Gln polymorphism is not associated with Non-Hodgkin Lymphoma.

17. Our present case-control study has shown that tryptophan allele (R/W-W/W genotype) in XRCC1A (Arg194Trp) gene significantly increased the risk of breast cancer 1.44-fold..the present case-control study did not reveal any significant association of XRCC3 (Thr241Met) polymorphism with the risk of breast cancer in females from NE region of India

18. The C allele of rs861539 and T allele of rs1799782 Interaction between rs1799782 and obesity and haplotype T- C were all associated with increased papillary thyroid cancer risk.

19. We confirmed that Arg399Gln polymorphism of XRCC1 gene is a potential predictor for susceptibility to NPC, especially for Asians

20. Review/Meta-analysis: XRCC1 Arg399Gln polymorphism might be associated with genetic susceptibility to systemic lupus erythematosus in Asians and Caucasians.

Mouse (Murine) X-Ray Repair Complementing Defective Repair in Chinese Hamster Cells 1 (XRCC1) Interaktionspartner

1. Unrepaired single strand DNA breaks (SSBs) activate DNA damage response and increase the expression of inflammatory cytokines through NF-kappaB signalling. Pressure overload-induced heart failure is more severe in the mice lacking XRCC1, an essential protein for SSB repair.

2. Interaction with phosphorylated XRCC1 is a requirement for significant APTX recruitment to cellular DNA damage and enzymatic activity in cell extracts.

3. this review focuses on the role of the oxidized form of XRCC1 in protection against extreme oxidative stress

4. Repair independent of the well documented XRCC1-PNKP interaction was studied. XRCC1 can mediate repair of strand breaks without PNKP binding.

5. data establish the importance of XRCC1 protein complexes for normal neurological function and identify PARP1 as a therapeutic target in DNA strand break repair-defective disease

6. We have characterized the nuclear localization signal (NLS) of XRCC1 structurally using X-ray crystallography and functionally using fluorescence imaging.

7. Its allelic loss results in increased brain damage and reduced recovery from ischemic stroke.

8. Data indicate that maternal folate depletion during pregnancy and high-fat feeding from weaning altered gene expression of Ogg1, Neil1, Mutyh and Xrcc1 in the brain of adult offspring.

9. In cells with DNA base damage, PAR serves to recruit XRCC1 that in turn binds and recruits pol beta, the primary DNA polymerase of the base excision repair pathway.

10. Lig4 and XRCC1 double-deficient cells switch as efficiently as Lig4-deficient cells, clearly indicating that XRCC1 is dispensable for A-EJ in CH12F3 cells during class switch recombination

11. findings firmly demonstrate that XRCC1 is not a requisite factor for A-EJ of chromosomal DSBs and raise the possibility that DNA ligase 1 (Lig1) may contribute more to A-EJ than previously considered

12. Data support a role for XRCC1 in microhomology-mediated joining, and imply that AID-induced single-strand breaks in Igh variable and switch regions become substrates simultaneously for BER and mutagenesis pathways.

13. Results indicates that XRCC1 haploinsufficiency has little effect on chronological longevity and many key biological markers of aging, but may adversely affect normal animal development or increase disease susceptibility to a relevant genotoxic exposure.

14. data reveal that the critical biological role of Lig3 is to maintain mtDNA integrity and not Xrcc1-dependent DNA repair

15. results establish a role for Lig3 in mitochondria, but distinguish it from its interacting protein Xrcc1
