Abstract
Peroxisomes play a role in lipid metabolism and regulation of reactive oxygen species, but its role in development and progression of non-small cell lung cancer (NSCLC) is not well understood. Here, we investigated the associations between 9708 single-nucleotide polymorphisms (SNPs) in 113 genes in the peroxisome-related pathways and survival of NSCLC patients from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) and the Harvard Lung Cancer Susceptibility (HLCS) study. In 1185 NSCLC patients from the PLCO trial, we found that 213 SNPs were significantly associated with NSCLC overall survival (OS) (p ≤ 0.05, Bayesian false discovery probability [BFDP] ≤ 0.80), of which eight SNPs were validated in the HLCS data set. In a multivariate Cox proportional hazards regression model, two independent SNPs (rs9384742 DDO and rs9825224 PEX5L) were significantly associated with NSCLC survival (hazards ratios [HR] of 1.17 with 95% CI [confidence interval] of 1.06-1.28 and 0.86 with 95% CI of 0.77-0.96, respectively). Patients with one or two protective genotypes had a significantly higher OS (HR: 0.787 [95% CI: 0.620-0.998] and 0.691 [95% CI: 0.543-0.879], respectively). Further expression quantitative trait loci analysis using whole blood and lung tissue showed that the minor allele of rs9384742 DDO was significantly associated with decreased messenger RNA (mRNA) expression levels and that DDO expression was also decreased in NSCLC tumor tissue. Additionally, high PEX5L expression levels were significantly associated with lower survival of NSCLC. Our data suggest that variants in these peroxisome-related genes may influence gene regulation and are potential predictors of NSCLC OS, once validated by additional studies.

Dr. Glass completed medical residency in Anatomic Pathology at the Brigham and Women’s Hospital/Harvard Medical School followed by fellowships in Cardiothoracic Pathology also at Brigham and Women’s Hospital/Harvard Medical School and Pulmonary/Cardiac Transplant Pathology at the University of Texas Southwestern Medical Center. Dr. Glass initially trained as a vascular surgeon with a focus on endovascular/interventional procedures through the 0+5 Integrated Vascular Surgery Program at the University of Rochester Medical Center from 2007-2011. As a recipient of the NIH National Lung Blood Institute T32 Ruth Kirschstein National Service Research Award, she completed a Ph.D with a concentration in Genomics and Epigenetics in 2014. Dr. Glass serves as P.I. of multiple NIH grants, including U54 and SBIR.
As a thoracic surgical pathologist, Dr. Glass diagnoses complex heart transplant rejection and thoracic malignancies. She works closely with the Duke Thoracic Oncology Group, DCI Center for Cancer Immunotherapy, Duke Division of Cardiovascular Medicine and Cardiothoracic Surgery and Pratt School of Biomedical Engineering.
Dr. Glass is the recipient of the Society of Cardiovascular Pathology (SCVP) Young Investigator’s Award, the William von Liebig Vascular Biology Research Fellowship at the Harvard Institutes of Medicine, the Duke Pathology Salvatore V. Pizzo Faculty Research Mentor Award, the Duke Department of Pathology Early Career Research Achievement Award and is author of over 85 publications (including book chapters in the recent W.H.O. Classification Tumours of the Lung, Pleura, Thymus and Heart) and 50 national presentations in cardiovascular disease, thoracic malignancies, surgery and machine learning.
In addition to her clinical and research activities, Dr. Glass serves on the Executive/National Committees for the Society of Cardiovascular Pathology, College of American Pathology Artificial Intelligence Committee and the Duke School of Medicine Executive Admissions Committee.
