Abstract

Ferritin heavy chain 1 (FTH1) is an ubiquitous and highly conserved protein which plays a major role in iron homeostasis. The expression of FTH1 was specifically enhanced under various condition of endoplasmic reticulum (ER) stresses drugs such as Brefeldin A (BFA), DTT (Dithiothreitol), calcium ionophore A23187 and tunicamycin. We firstly report here that ER-stress induces up-regulated expression of FTH1 in FRTL-5 culture thyrocytes.
