ABSTRACT
BACKGROUND/AIM:
Impaired DNA repair capacity may play a critical role in genome instability and carcinogenesis. However, the impact of DNA ligase 1 (Lig1) genotypes on tumorigenesis remains unclear. This study aimed to investigate the contribution of Lig1 rs20579 genotypes to the risk of developing lung cancer, and review the related literature. MATERIALS ANDMETHODS:
Polymerase chain reaction-restriction fragment length polymorphism analysis was used to determine the genotypes of Lig1 rs20579 and evaluate their association with lung cancer risk among 358 lung cancer cases and 716 age- and sex-matched cancer-free control subjects.RESULTS:
The distribution of GG, AG, and AA genotypes for Lig1 rs20579 was 77.1%, 20.8%, and 2.1% among the controls, and 76.0%, 21.5%, and 2.5% among the lung cancer cases (p for trend=0.8686). There was no significant difference in the distribution of AG and AA genotypes between the two groups (p=0.8257 and 0.8098, respectively). Allelic frequency analysis indicated that individuals carrying the variant A allele for Lig1 rs20579 had a non-significant 1.07-fold higher risk of developing lung cancer than those carrying the wild-type G allele [95% confidence interval (CI)=0.82-1.40, p=0.6639]. Furthermore, no differential distribution of the Lig1 rs20579 genotype was found among non-smokers (p=0.9910) or smokers (p=0.9001).CONCLUSION:
In contrast to Americans, Lig1 rs20579 genotypes do not appear to play a critical role in determining susceptibility to lung cancer among Taiwanese individuals.Palavras-chave
