Abstract

The oncogenic role of many of inflammatory genes in prostate cancer (PCa) remains unexplored despite the increasing association of chronic inflammation with PCa initiation, progression, and therapy resistance. The overarching goal of this project was to identify dysregulated inflammatory genes that correlate with PCa progression and seek to understand their molecular mechanisms and the therapeutic potential of targeting them. To achieve this, we utilized cutting-edge integrative (epi) genomic and transcriptomic techniques to identify and characterize inflammatory genes whose deregulation or (epi) genetic alterations correlate with PCa progression. Weighted Gene Co-expression Network Analysis and other multivariate analysis techniques identified IRAK1 as one of the inflammatory signatures found to be overexpressed in over 80% of prostate adenocarcinoma (PRAD) samples. We also explored the diagnostic and prognostic potential of IRAK1 as a biomarker using Kaplan Meier Survival Analysis and AUROC Analysis. DNA methylation analysis showed that IRAK1 is hypomethylated and found to negatively correlate with its overexpression in PRAD patients. We also found some missense and truncated mutations in some patients and reported a high level of IRAK1 gene amplification in castration-resistant and neuroendocrine PCa patients.
