Effect of various metabolic inhibitors on the agglutination of rat ascites tumor cells mediated by concanavalin A and Ricinus communis agglutinin was studied using a quantitative assay method for agglutination in which turbidity of cell suspension is measured. Cell agglutination was inhibited by low
The vascularization of intracerebral transplantation tumors of the two rat glioma clones RG2 and F98 was studied in various stages of progressive tumor growth by use of biotinylated Ricinus communis agglutinin I (B-RCA I) in avidin-biotin-peroxidase complex (ABC)-histochemistry. The tumors were
Allomyrina dichotoma lectin (allo A) with a specificity to beta-D-galactose was used to fractionate human alpha-fetoprotein (AFP) by affinity electrophoresis. AFP from cord sera and serum of a patient with fulminant hepatitis showed single bands with a high affinity for allo A. Some patients with
The binding of Ricinus communis lectins to HeLa cells, Sarcoma 180 ascites tumor cells and human erythrocytes was studied in detail. Scatchard plots of binding of 125I-lectins to these cells gave biphasic lines except for HeLa cells at 0 degree C. The association constants of lectins for the three
Ricinus communis agglutinin I (RCA I), a galactose-binding lectin from castor beans, binds to endothelial cells at sites of plasma leakage, but little is known about the amount and functional consequences of binding to tumor endothelial cells. We addressed this issue by examining the effects of RCA
In this study, a liquid-phase separation platform consisting of tandem lectin affinity chromatography was introduced for the selective capturing of sub-glycoproteomics that are affected in cancers, e.g. breast cancer. The platform is comprised of three monolithic columns with surface immobilised
Using Ricinus communis agglutinin I (RCA-I) affinity crossed-line immunoelectrophoresis, alpha-fetoprotein (AFP) subfractions were studied in sera from patients with primary hepatic cancer (PHC), hepatic metastasis of gastric cancer (HMGC), yolk sac tumor (YST), acute or chronic hepatitis or hepatic
Rapidly developing tumours at hypocotyls of Ricinus communis, induced by Agrobacterium tumefaciens strain C58, were characterized by strong differentiation of vascular bundles and their functional connection to the host bundles. The stem/tumour interface showed increased xylem, with numerous vessels
Tumour necrosis factor-alpha (TNF-alpha) is one of the most prominent inflammatory mediators playing a central role in starting off the inflammatory reactions of the innate immune system. We identified a TNF-alpha-inhibitory activity in the saliva and salivary gland extract (SGE) from partially fed
Medicinal plant-based therapies can be important for treatment of cancer owing to high efficiency, low cost and minimal side effects. Here, we report the anti-cancer efficacy of Ricinus communis L. fruit extract (RCFE) using estrogen positive MCF-7 and highly aggressive, triple negative MDA-MB-231
The effects of the sequential application of specific glycosidases on surfaces of living mammalian cells were studied with respect to their ability to bind the beta-galactoside-specific lectin, Ricinus communis agglutinin (RCA). Sialidase and beta-galactosidases from different sources were tested
Ricinus communis agglutinin I(RCAI) receptors in 25 cases of hepatocellular carcinoma and 6 cases of intrahepatic cholangiocellular carcinoma were immunohistochemically localized by avidin-biotin-peroxidase complex (ABC) method. In the meantime, RCAI receptors in normal and cirrhotic liver tissues
