▶Variation in PAH‐related DNA adduct levels among non‐smokers: The role of multiple genetic polymorphisms and nucleotide excision repair phenotypeAssociationN=111Arash Etemadi et al.(2013)· International Journal of Cancer
This study examined PAH-related DNA adduct levels in 111 female never-smokers from Iran, evaluating 21 SNPs in 14 xenobiotic metabolism genes and 12 SNPs in 8 DNA repair genes. DNA adduct levels were significantly lower with NAT2 slow alleles (β=-0.24, p=0.01) and ERCC5 non-risk genotype (β=0.16, p=0.04), but higher with MPO risk alleles (β=0.21, p=0.01). The combination of phase I genes and measured NER capacity explained 17% more variation in adduct levels than environmental exposure alone (r²=0.24 vs 0.07), demonstrating the importance of genetic polymorphisms in PAH metabolism and DNA repair capacity.
About ERCC1
The product of this gene functions in the nucleotide excision repair pathway, and is required for the repair of DNA lesions such as those induced by UV light or formed by electrophilic compounds including cisplatin. The encoded protein forms a heterodimer with the XPF endonuclease (also known as ERCC4), and the heterodimeric endonuclease catalyzes the 5' incision in the process of excising the DNA lesion. The heterodimeric endonuclease is also involved in recombinational DNA repair and in the repair of inter-strand crosslinks. Mutations in this gene result in cerebrooculofacioskeletal syndrome, and polymorphisms that alter expression of this gene may play a role in carcinogenesis. Multiple transcript variants encoding different isoforms have been found for this gene. The last exon of this gene overlaps with the CD3e molecule, epsilon associated protein gene on the opposite strand. [provided by RefSeq, Oct 2009]
