Moderate iron deficiency and high dietary iron intake differentially alter hepatic lipid metabolism and adipose tissue lipid handling in mice

These findings demonstrate that moderate iron deficiency and high iron intake disrupt hepatic lipid metabolism via different pathways: FeD primarily through systemic adaptations leading to post-translational constraints on iron-dependent enzymes, whereas FeH acts through direct transcriptional activation of hepatic <i>de novo</i> lipogenesis, potentially involving hepcidin-mediated cross-talk. The study underscores the critical importance of iron homeostasis in preventing dyslipidemia and hepatic steatosis and provides mechanistic insights that could inform dietary recommendations for populations at risk of metabolic disorders.
