Placental Iron Utilisation in Fetal Growth Restriction: Alterations in Mitochondrial Heme Synthesis and Iron-Sulfur Cluster Assembly Pathways

Veronica B. Botha, Heather C. Murray, Siddharth Acharya, Kirsty G. Pringle, Roger Smith, Joshua J. Fisher

This study investigates iron utilization in placental tissues of fetal growth restriction (FGR) pregnancies, revealing increased iron uptake and prioritization of heme synthesis over iron-sulfur cluster formation.
