Subject:
aluminum; capillary electrophoresis; endocytosis; humans; hydrodynamics; ions; iron; light scattering; pH; toxicity; transferrin
Abstract:
... Human transferrin (Tf) very tightly binds two ferric ions to deliver iron to cells. Fe(III)₂Tf (Fe₂Tf) binds to the Tf receptor (TfR) at pH 7.4; however, iron-free Tf (apoTf) does not. Iron uptake is facilitated by endocytosis of the Fe₂Tf-TfR complex. Tf can also bind aluminum ions, which cause toxic effects and are associated with many diseases. Since Al(III)₂Tf (Al₂Tf) does not bind to TfR, the ...

Abstract:
... Selenium-containing thioredoxin reductase (TrxR) is an important target of cancer therapy. Many useful anticancer agents including bis-alkylating agents, cisplatin, and arsenic trioxide are known to interact with the selenocysteine dipeptide in the carboxy terminal region of thioredoxin reductase and inactivate its ability to reduce thioredoxin. Some investigators have postulated that the inactiva ...
