the present study , was an attempt to develop galactosylated albumin nanoparticles of simvastatin for treatment of hypercholesterolemia. by developing the galactosylated nanoparticulated delivery the required action of drug at the target site at liver can be provided. the advantage of targeting helps to reduce the systemic side effects which may be occur due to the distribution of the drug to t...
in the present study, an attempt was made to develop galactosylated albumin nanoparticles of cimetidine for treatment of acetaminophen induced hepatotoxicity. by developing the galactosylated nanoparticulated delivery of cimetidine the required action of drug at the target site i.e at liver can be provided. the advantage of targeting helps to reduce the systemic side effects which may be occur ...
The binding of rat hepatocytes to flat polyacrylamide surfaces containing galactose is sugar-specific, requires Ca+2, and occurs only above a critical concentration of sugar in the substratum [Weigel et al., 1979, J. Biol. Chem., 254, 10,830). Binding is completely inhibited by asialo-orosomucoid but not by orosomucoid or asialo-agalacto-orosomucoid, suggesting that cell binding is mediated by ...
The human asialoglycoprotein receptor was isolated via immune precipitation from hepatoma Hep G2 cells following incubation with [32P]Pi. Analysis on sodium dodecyl sulphate/polyacrylamide-gel electrophoresis revealed incorporation of 32P into both the 46 000 Da mature form of the receptor as well as the 40 000 Da precursor. The incorporated 32P was associated with phosphoserine. The degree of ...
Biotin regulation of asialoglycoprotein receptor expression and insulin receptor activity has been established in two human hepatoblastoma cell lines, Hep G2 and HuH-7. Second messenger cGMP mimics the effect of biotin on asialoglycoprotein receptor expression at the translational level. Metabolic labeling and subsequent immunoprecipitation indicate that the loss of insulin receptor activity du...
Glycosylation of biopharmaceuticals can mediate cell specific delivery by targeting carbohydrate receptors. Additionally, glycosylation can improve the physico-chemical (drug-like) properties of peptide based drug candidates. The main purpose of this study was to examine if glycosylation of the peptide enkephalin could facilitate its binding to the carbohydrate receptor, asialoglycoprotein. Fir...
The influence of cell density on expression of the asialoglycoprotein receptor system in primary cultures of rat hepatocytes was evaluated by measuring the level of the receptor specific mRNA. When the hepatocytes are cultured at high cellular density and are not in a proliferative condition, the transcript molecules of the receptor appear increased about 50% with respect to the low plating den...
