Unlike IDA rats without HF, in Dahl salt-sensitive HF rats, it was found that intestinal expression of important genes for intestinal iron absorption such as duodenal cytochrome b (Dcyt-b), divalent metal transporter 1 (DMT-1) and ferroprotein was not upregulated in spite of reduced hepcidin expression [114]. Here, HAMP is linked to hydrops fetalis.
