If the iron-transporting proteins are missing or defective, iron can't cross membranes, resulting in anemia. The researchers tested hinokitiol in mice, rats, zebrafish, and in human cells that were missing iron-transport proteins, and showed that hinokitiol could package iron atoms in a way that facilitated transport across membranes.
