Drug-induced erythrocyte membrane internalization.
In vitro erythrocyte membrane internalization, resulting in the formation of membrane-lined vacuoles, can be quantified by a radioisotopic method. A complex of (37)Co-labeled vitamin B(12) and its plasma protein binders is first adsorbed to the cell surface, and after vacuoles are formed, the noninternalized label is removed by washing and trypsin treatment. The residual radioactivity represent...
متن کاملSulfhydryl groups of the erythrocyte membrane and their relation to glycolysis and drug-induced hemolytic anemia.
Hemolytic anemia caused by oxidative drugs is thought to result from the oxidation of intracellular and membrane sulfhydryl groups of the erythrocyte. This process is more likely to occur in those erythrocytes in which the intracellular mechanism for reduction of disulfides is abnormal (e.g., glucose-6-phosphate dehydrogenase deficiency). If a membrane sulfhydryl group is critical in the pathog...
متن کاملThe anticancer drug cisplatin interacts with the human erythrocyte membrane.
Drugs which exert their effects by interacting with DNA cause structural and functional membrane alterations which may be essential for growth inhibition by these agents. This paper describes the interaction of cisplatin with the human erythrocyte membrane and models constituted by bilayers of dimyristoylphosphatidylethanolamine (DMPE) and diacylphosphatidylserine (DAPS), representative of phos...
متن کاملThe anticancer drug adriamycin interacts with the human erythrocyte membrane.
Adriamycin is an aminoglycosidic anthracycline antibiotic widely used in the treatment of cancer. Increasing reports point to the involvement of cell membranes in its mechanism of action. The interaction of adriamycin with human erythrocytes was investigated in order to determine the membrane binding sites and the resultant structural perturbation. Electron microscopy revealed that red cells in...
متن کاملConstitutive and antibody-induced internalization of prostate-specific membrane antigen.
Prostate-specific membrane antigen (PSMA) is a cell surface glycoprotein expressed predominantly by prostate cancer cells. We have characterized four monoclonal antibodies that bind to the extracellular domain of PSMA (Liu et al., Cancer Res., 57: 3629-3634, 1997). Here we report that viable LNCaP cells internalize these antibodies. Laser scanning confocal microscopy reveals that the internaliz...
