[Lectin receptors in transitional cell tumors of the bladder].
Binding sites for lectins of peanuts, soya-beans and concanavalin A were identified in the tissues of normal human urinary bladder and its transitional cell tumors (31 patients) using the lectin-peroxidase technique. No binding sites for any of the lectins were found in normal urothelium. Receptors for peanut and soya-bean lectins were observed on the plasma membranes of 20% of tumor cells in transitional cell papillomas. A diffuse distribution of those lectins in tumor cell cytoplasm was interpreted as a tendency to malignant transformation of tumor. There were no concanavalin A receptors in tumor cells.
