Potential protective effects of zinc in iron overload

zinc–iron transporter. Though studies have shown that zinc treatment increases expression of DMT1 (4), it is unlikely to account for the decreased iron content in the cells treated with zinc–iron observed by Formigari et al. as any regulation of DMT1 would effect both metals. It wouldbemorelikelythattheremayhavebeencompeti-

Acute inhibition of iron absorption by zinc - ScienceDirect

May 01, 2007  The mechanisms involved in the interaction between zinc and iron are not fully understood. It has been proposed that zinc and iron compete for a shared absorptive pathway. This negative interaction could be explained by a competitive binding to the divalent metal transporter 1 (DMT1), a proton-coupled transporter of a variety of divalent metals
