A pooled analysis of host factors that affect nucleotide excision repair in humans
Original language description
Nucleotide excision repair (NER) is crucial for repairing bulky lesions and crosslinks in DNA caused by exogenous and endogenous genotoxins. The number of studies that have considered DNA repair as a biomarker is limited, and therefore one of the primary objectives of the European COST Action hCOMET (CA15132) was to assemble and analyze a pooled database of studies with data on NER activity. The database comprised 738 individuals, gathered from 5 laboratories that ran population studies using the comet-based in vitro DNA repair assay. NER activity data in peripheral blood mononuclear cells (PBMCs) were normalized and correlated with various host-related factors, including sex, age, body mass index (BMI), and smoking habits. This multifaceted analysis uncovered significantly higher NER activity in female participants compared to males (1.08 +- 0.74 vs. 0.92 +- 0.71; P = 0.002). Higher NER activity was seen in older subjects (> 30 years), and the effect of age was most pronounced in the oldest females, particularly those over 70 years (P = 0.001). Females with a normal BMI (< 25 kg/m2) exhibited the highest levels of NER, whereas the lowest NER was observed in overweight males (BMI >= 25 kg/m2). No independent effect of smoking was found. After stratification by sex and BMI, higher NER was observed in smoking males (P = 0.017). The biological implication of higher or lower repair capacity remains unclear; the inclusion of DNA repair as a biomarker in molecular epidemiological trials should elucidate the link between health and disease status.
