Excess dietary iron in tumor tissues was also associated with significant changes (generally, increases; p ≤ 0.05) in proteins involved in modulating cell protein integrity (HSPA5, HSPA9, ITGB1, PSMA4, DPP7, and PEPD), cell mobility and growth (CAPZB), and immunologic factors (FCGBP). This evidence concerns the gene CAPZB and neoplasm.
