In our previous work (Alexandrov et al., 1996) was reported that the rat sarcoma cells induced by SR-RSV express two tumor associated antigens (TAA). The one TAA has a molecular weight of 52 kD and is detected by the help of a monoclonal antibody 2C2 only on the outer side of the plasma membrane of
Lectin binding patterns in ten mouse malignant fibrous histiocytoma (MFH)-like sarcomas containing eosinophilic globule (EG) cells and in granular metrial gland (GMG) cells of mouse placenta were stained with nine lectins (Con A, LCA, WGA, DBA, SBA, e-PHA, PNA, RCA-I and UEA-I) by an
Selective interplay between proteins and carbohydrates of cellular glycoconjugates offers the potential to mediate physiologically important biorecognition and biosignaling, relevant to metastasis formation. Biotinylated neoglycoproteins were therefore employed as tools to detect endogenous sugar
The potential for encoding information in carbohydrate (CHO) structures has long been recognized. Selective CHO-binding proteins known as lectins and the biological events they mediate are well known. However, many lectins were originally discovered for biological activities other than saccharide
Acute (hepatitis) and chronic (cirrhosis) liver injuries were experimentally induced in BALB/c-mice by administration of D-galactosamine and carbon tetrachloride, respectively. In both experimental liver diseases the incidence of hepatic tumor colonization of sarcoma L-1 was significantly reduced as
Oval cells appear and expand in the liver when hepatocyte proliferation is compromised. Many different markers have been attributed to these cells, but their nature still remains obscure. This study is a detailed gene expression analysis aimed at revealing their identity and repopulating in vivo
The extent of lectin binding by three human melanoma (LOX, FEMX-1 and SESX) and two sarcoma lines (MHMX and OHSX) was related to their potential for experimental metastasis formation in athymic nude mice. The Helix pomatia agglutinin (HPA), which recognises the N-acetyl-D-galactosamine ligand,
Nicotinamide methyltransferase (Nmd CH3transferase) activity increased in the liver of mice after i.p. transplantation of Ehrlich ascites tumor (ascitic form), but not in the liver of mice with acute inflammation induced by the i.p. administration of D-galactosamine, and it rather showed a decrease
Tumor necrosis can be induced in transplanted mouse methylcholanthrene-induced sarcoma by a tumor necrosis factor in the serum of mice infected with bacillus Calmette-Guérin and given bacterial endotoxin. Sera from normal mice, endotoxin-treated mice, and mice infected with bacillus Calmette-Guérin
