Abstract
Pancreatic cancer (PanC) is one of the most lethal solid malignancies, and metastatic PanC is often present at the time of diagnosis. Although several high- and low-penetrance genes have been implicated in PanC, their roles in carcinogenesis remain only partially elucidated. Because the nuclear factor erythroid2-related factor2 (NRF2) signaling pathway is involved in human cancers, we hypothesize that genetic variants in NRF2 pathway genes are associated with PanC risk. To test this hypothesis, we assessed associations between 31 583 common single nucleotide polymorphisms (SNP) in 164 NRF2-related genes and PanC risk using three published genome-wide association study (GWAS) datasets, which included 8474 cases and 6944 controls of European descent. We also carried out expression quantitative trait loci (eQTL) analysis to assess the genotype-phenotype correlation of the identified significant SNP using publicly available data in the 1000 Genomes Project. We found that three novel SNP (ie, rs3124761, rs17458086 and rs1630747) were significantly associated with PanC risk (P = 5.17 × 10-7 , 5.61 × 10-4 and 5.52 × 10-4 , respectively). Combined analysis using the number of unfavorable genotypes (NUG) of these three SNP suggested that carriers of two to three NUG had an increased risk of PanC (P < 0.0001), compared with those carrying zero to one NUG. Furthermore, eQTL analysis showed that both rs3124761 T and rs17458086 C alleles were associated with increased mRNA expression levels of SLC2A6 and SLC2A13, respectively (P < 0.05). In conclusion, genetic variants in NRF2 pathway genes could play a role in susceptibility to PanC, and further functional exploration of the underlying molecular mechanisms is warranted.

Kyle Walsh
Dr. Walsh is Associate Professor of Neurosurgery and Pathology, Director of the Division of Neuro-epidemiology, and a Senior Fellow in the Duke Center for the Study of Aging and Human Development. He leads Duke’s Neuro-epidemiology Lab, which integrates bench science with statistical methods to study the neurobiology of glial senescence and gliomagenesis. This research interrogates human genomic and epigenomic profiles to identify both heritable and modifiable factors that contribute to neurologic and physical decline, applying these approaches to studying the shared neurobiology of cognition, glial senescence, and gliomagenesis. The lab has a long history studying telomere maintenance in pre-malignant cells and its role in the development of cancer, most notably glioblastoma.
