Divalent metal transporter-1 (DMT1) is a divalent cation transporter that plays a key role in iron metabolism by mediating ferrous iron uptake across the small intestine. We have previously identified several small molecule inhibitors of iron uptake (4). Using a cell line that stably overexpresses DMT1, we screened the ability of these inhibitors to specifically block this transporter's activit...
Disrupted iron metabolism has been implicated in the pathogenesis of Parkinson's disease (PD), a progressive neurodegenerative disorder that severely affects movement and coordination, yet the molecular mechanisms underlying this association remain unknown. To this end, we performed a transcriptomic meta-analysis of four blood microarrays in PD. We observed a significant downregulation of genes...
BACKGROUND Hepcidin plays a key role in body iron metabolism by preventing the release of iron from macrophages and intestinal cells. Defective hepcidin synthesis causes iron loading, while overproduction results in defective reticuloendothelial iron release and iron absorption. DESIGN AND METHODS We studied a Sardinian family in which microcytic anemia due to defective iron absorption and ut...
The reactivity of the essential element iron necessitates a concerted expression of ferritins, which mediate iron storage in a nonreactive state. Here we have further established the role of the Helicobacter pylori ferritin Pfr in iron metabolism and gastric colonization. Iron stored in Pfr enabled H. pylori to multiply under severe iron starvation and protected the bacteria from acid-amplified...
