Prooxidant activity of transferrin and lactoferrin
Acceleration of the autoxidation of Fe2+ by apotransferrin or apolactoferrin at acid pH is indicated by the disappearance of Fe2+, the uptake of oxygen, and the binding of iron to transferrin or lactoferrin. The product(s) formed oxidize iodide to an iodinating species and are bactericidal to Escherichia coli. Toxicity to E. coli by FeSO4 (10(-5) M) and human apotransferrin (100 micrograms/ml) ...

Distribution of transferrin, ferritin, and lactoferrin in human tissues.
An immunoperoxidase staining technique was used for detecting three major iron-binding proteins (transferrin, ferritin, and lactoferrin) in routine histological paraffin sections of human tissue. Transferrin was found mainly in hepatocytes, a variety of epithelial and myoepithelial cells, renal tubular cells, and histiocytes. Ferritin was most readily found in histiocytes and liver cells, with ...
متن کاملDistribution of ferritin, transferrin and lactoferrin in breast carcinoma tissue.
An immunoperoxidase staining technique was used for detecting three major iron binding proteins (ferritin, transferrin and lactoferrin) in 40 breast carcinoma cases and six benign breast proliferative lesions. Ferritin staining was detected mainly in connectival stroma and in histiocytes surrounding neoplastic cells. Few and faint ferritin positivities were also detected in neoplastic cells of ...
متن کاملLactoferrin In Vivo and the Comparative Action of Human Transferrin
Purified human lactoferrin was assessed for its influence in vivo in untreated mice and in mice undergoing rebound myelopoiesis after sublethal dosages of Cytoxan. Fully iron-saturated lactoferrin suppressed the numbers of granulocytes and monocytes per femur, the numbers of granulocyte-macrophage progenitor cells (CFU-GM) per femur and spleen. and decreased the cycle status of femoral and sple...
