Global Proteomic Profiling in Chronic Iron-Exposed Fallopian Tube Secretory Epithelial Cells

We previously published (Oncogenesis, Rockfield et al., 2019) that chronic iron exposure (with ferric ammonium citrate, FAC) in immortalized fallopian tube secretory epithelial cells resulted in increased growth and migratory propensity. Our focused analyses identified a subset of oncogenic markers, including EVI1 (amplified at 3q26.2 in high grade serous epithelial ovarian tumors), that were altered following long term iron treatment. Herein, we have extended these studies to global proteomics analyses via a mass spectrometry (MS)-based approach.
