The lectin hepatic binding protein has a specific binding capacity for desialylated serum glycoproteins and is limited to hepatocyte membranes. This binding capacity was reduced by approximately 60% in the neoplastic nodules which resulted from exposure of rat livers to N-2-acetylaminofluorene. The binding capacity of the primary hepatocellular carcinomas which resulted from this regimen was re...
Lectins are a class of ubiquitous proteins/glycoproteins that are abundantly found in nature. Lectins have unique carbohydrate binding property and hence have been exploited as drugs against various infectious diseases. We have isolated one such novel lectin from the fruit pulp of Aegle marmelos. The isolated lectin was partially characterised and its effect against Shigella dysenteriae infecti...
The toxic effect of Ricinus lectin RCA I, as estimated by the inhibition of [3H]leucine incorporation, was investigated on chick-embryo fibroblasts at different stages of development. There appeared to be a differential susceptibility of chick-embryo fibroblasts to lectin RCA I. Fibroblasts from 16-day embryos were the most sensitive to its toxic effect in terms of both concentration and time, ...
A novel mammalian lectin activity responsive to monocytic differentiation is described in the human promyelocytic leukemia cell line HL-60. Glycoprotein binding indicates that the lectin recognizes both N-acetylneuraminic acid and galactose-terminating biantennary oligosaccharide structures. Lectin activity is independent of calcium and appears to reside in a Mr 17,000 intracellular membrane pr...
The binding proteins for Sarcophaga lectin and wheat germ agglutinin on the surface of Ehrlich ascites tumor cells were compared. Studies with antibody against the binding protein for Sarcophaga lectin showed that these two binding proteins are different. Since these two lectins are both active in the lectin-dependent macrophage-mediated cytotoxic reaction with Ehrlich ascites tumor cells as ta...
