After receptor-mediated uptake, asialoglycoproteins are routed to lysosomes, while transferrin is returned to the medium as apotransferrin. This sorting process was analyzed using 3,3'-diaminobenzidine (DAB) cytochemistry, followed by Percoll density gradient cell fractionation. A conjugate of asialoorosomucoid (ASOR) and horseradish peroxidase (HRP) was used as a ligand for the asialoglycoprot...
Asialoglycoproteins are taken up by the rat liver for degradation; rat polymeric IgA is taken up via a separate receptor, secretory component (SC), for quantitative delivery to bile. There is negligible uptake of these ligands by the converse receptor, and only a low level of missorting of ligands to opposite destinations. The two pathways are not cross-inhibitable and operate independently (Sc...
The Kupffer cell receptor for glycoproteins has been reported to have a role in clearance of galactose- and fucose-terminated glycoproteins from circulation. Although the gene and a cDNA encoding the receptor have been described, there has been little study of the receptor protein. To address some questions about possible ligands and functions for this receptor, fragments representing portions ...
Anti-sense oligodeoxynucleotides (ODNs) hold great promise for correcting the biosynthesis of clinically relevant proteins. The potential of ODNs for modulating liver-specific genes might be increased by preventing untimely elimination and by improving the local bioavailability of ODNs in the target tissue. In the present study we have assessed whether the local ODN concentration can be enhance...
In this study, we evaluated the effect of blood components (whole blood and serum) on asialoglycoprotein receptor-mediated in vivo gene transfer. The hepatic transfection activity of galactosylated lipoplex preincubated with serum was approximately 10 times higher than that without incubation after intraportal injection in mice. However, preincubation with whole blood significantly reduced hepa...
We used lactoperoxidase-mediated iodination to investigate the lumenal polypeptide composition of rat hepatocyte endosomes. A chemical conjugate of asialoorosomucoid and lactoperoxidase that binds specifically to hepatocyte asialoglycoprotein receptors was perfused through isolated rat livers at 16 "C in the presence of mannan, resulting in the accumulation of ligand in early endosomes. Endosom...
