Stories about: iron deficiency

Naturally-occurring molecule in tree leaves could treat anemia, other iron disorders

“Without iron, life itself wouldn’t be feasible,” says Barry Paw, MD, PhD. “Iron transport is very important because of the role it plays in oxygen transport in blood, in key metabolic processes and in DNA replication.”

Although iron is crucial to many aspects of health, it needs the help of the body’s iron-transporting proteins. Which is why new findings reported in Science could impact a whole slew of iron disorders, ranging from iron-deficiency anemia to iron-overload liver disease. The team has discovered that a small molecule found naturally in Japanese cypress tree leaves, hinokitiol, can transport iron to overcome iron disorders in animals.

The multi-institutional research team is from the University of Illinois, Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, Brigham and Women’s Hospital and Northeastern University. Paw, co-senior author on the new paper and a physician at Dana-Farber/Boston Children’s, and members of his lab demonstrated that hinokitiol can successfully reverse iron deficiency and iron overload in zebrafish disease models.

“Amazingly, we observed in zebrafish that hinokitiol can bind and transport iron inside or out of cell membranes to where it is needed most,” says Paw.

This gives hinokitiol big therapeutic potential.
