Regulation of hepatic hepcidin expression by transferrin receptor-2
Hereditary hemochromatosis (HH) is a common inherited disorder. Iron overload results in damage to specific organs including the liver, heart, and pancreas resulting in cirrhosis of the liver, liver cancer, diabetes, cardiomyopathy. Iron also accumulates in joints causing arthritis. The liver is the major iron-sensing organ and controls iron homeostasis in the body. Mutations in transferrin receptor 2 (TfR2), HFE and hemojuvelin (HJV) lead to HH. TfR2 is hypothesized to sense iron in the body. The role that TfR2 plays in sensing iron remains controversial. The association between TfR2 and HFE is still debated. TfR2 also associates with HJV in vitro. We propose to determine the mechanisms by…
