My research interests are in the general area of iron biochemistry and are part of a major international effort to understand the role of iron in health and disease. Iron is an
element where you “Can’t
live without it but you can’t live with too much of it”. It is an essential element for
most forms of life but at the same time presents a danger to the cell
if it is not tightly regulated. To reduce the
threat posed by iron, living organisms sequester iron with transferrin, a plasma
transport protein which carries
iron in the circulation from the gut to the bone marrow and other
tissues for the synthesis of hemoglobin and
other iron containing proteins. The iron
loaded transferrin delivers its content of iron by endocytosis
after interaction with its receptor on the cell membrane.
Once inside the cell, iron is released and stored in ferritin, the major
iron storage protein in the human body. By
binding iron tightly, transferrin helps to avoid the
formation of free radicals reactions catalyzed by iron.
These reactions are implicated in the formation of various
cancers, arteriosclerosis, arthritis, and liver and heart diseases. Transferrin is also the target of chelation
therapy used to treat individuals with diseases of iron overload such
as “Thalassemia” and “Hemochromatosis”,
the most common genetic disorder in this country, affecting 1 out of
200 individuals. The uptake and
release of iron by transferrin and ferritin is a key
cellular process occurring during the normal course of iron
metabolism. These proteins are important
for the human health as body levels and forms of iron must be appropriately
maintained.
