Student Scholar Symposium Abstracts and Posters
Field cancerization is formally defined as the presence of molecular alterations in structurally normal tissues adjacent to tumors. Currently, the etiology of prostate field cancerization is still unknown. We hypothesize that exosomes (vesicles excreted by cells that may contain protein, lipids, or RNA) are released by tumors and are endocytosed by adjacent normal cells converting them into abnormal cells, thereby aiding cancer progression. The following biomarkers have been associated with field cancerization: MIC-1, PDGF-A, FASN, and EGR-1, while markers for exosomes are CD-9, CD-63, and PSMA. To test this hypothesis, exosomes were isolated from human prostate cancer cell models LNCaP …
