Iron, KDM4D, and MSC Quiescence via Foxo1
2026-08-15
The 2024 study identifies an iron-sensitive KDM4D–PIK3R3–PI3K–Akt–Foxo1 axis that controls whether bone marrow mesenchymal stem cells remain quiescent or become activated. Its findings connect impaired histone demethylation under iron deficiency with defective MSC mobilization and reduced bone mass, while pathway modulation partially reverses the skeletal phenotype.
