WebThe IRE/IRP System in Systemic Iron Metabolism. Systemic iron metabolism is regulated by hepcidin, a peptide hormone synthesized by liver hepatocytes, which targets ferroportin in … WebSep 6, 2024 · The IRE/IRP system accounts for coordinate post-transcriptional regulation of iron metabolism proteins in cells (Wang and Pantopoulos, 2011; Muckenthaler et al., 2008). In a homeostatic response to iron deficiency, IRPs bind to the IRE within the Slc40a1(+IRE) and ferritin (Fth1 and Ftl1) mRNAs, inhibiting their translation. IRE/IRP ... greatwide texas
