The soluble
receptor for advanced glycation end-products (sRAGE) is shown to mitigate pro-inflammatory effects triggered by
ligation of RAGE with N(ε)-
carboxymethyl-lysine (CML)-AGE or other
ligands. We examined the associations among host, lifestyle, and genetic determinants of CML-AGE or sRAGE and risk of
pancreatic cancer in the prospective ATBC Study. We obtained baseline exposure information, data on serological and genetic
biomarkers from 141 patients with
pancreatic cancer and 141 subcohort controls. Stepwise linear and logistic regression models were used for data analysis. Multiple linear regression analyses showed that CML-AGE concentrations were independently inversely correlated with the minor allele of rs640742 of DDOST, physical activity, alcohol consumption, diastolic blood pressure (BP), and positively correlated with heart rate, serum sRAGE and HDL concentrations (P < 0.05). sRAGE concentrations were independently inversely correlated with the 82Ser allele of rs2070600 of RAGE, age, body mass index, heart rate, and serum HDL; and positively correlated with serum CML-AGE,
sucrose consumption, and diastolic BP (P < 0.05). The minor allele of rs1035786 of RAGE was associated with reduced risk of
pancreatic cancer (any T compared with CC: multivariate OR = 0.61, 95% CI: 0.38-0.98). We identified host metabolic profile, lifestyle and genetic factors that explained approximately 50% of variability of CML-AGE or sRAGE in Finnish men smokers. The association between RAGE SNPs and
pancreatic cancer risk warrants further investigation.
