Expression of the transferrin receptor in human anterior pituitary adenomas is confined to gonadotrophinomas

Abstract

These findings may reflect a special requirement for iron by gonadotrophin secreting cells in comparison to other pituitary cell types and this could underlie the reasons why in the normal pituitary these cells are especially susceptible to malfunction in iron overload syndromes such as genetic haemochromatosis and beta-thalassaemia.
