摘要
To develop new treatments for beta-thalassemia, it is essential to identify the genes involved in the relevant pathophysiological processes. Iron metabolism in thalassemia mice being investigated, focusing on the expression of a gene called hepcidin (Hamp), which is expressed in the liver and whose product (Hamp) is secreted into the bloodstream. In mice, iron overload leads to overexpression of Hamp, while Hamp-knockout mice suffer from hemochromatosis. The aim of this study is to investigate Hamp in the mouse model of beta-thalassemia and to address the potential gene transfer of Hamp to prevent abnormal iron absorption.
