1. Five perchloric acid-soluble fractions (PASFs) obtained from ascitic fluids of three patients with primary hepatocellular carcinoma (HCC), a patient with liver metastatic carcinoma (LUC) from ureteral carcinoma and human normal serum (NS) were subjected to DEAE-cellulose column chromatography to separate seven glycoprotein fractions, respectively. 2. In this chromatography, two HCC-PASFs gave a Thomsen-Friedenreich (T)-active glycoprotein, respectively. 3. Other HCC-PASF gave a T-active glycoprotein, two blood group N antigen precursor glycoproteins and an N antigen precursor glycoprotein with T activity. 4. LUC-PASF gave two T-active glycoproteins and an N antigen precursor glycoprotein with T activity. 5. NS-PASF did not give these serologically active glycoproteins.

The levels of natural antibody against Thomsen-Friedenreich (TF) antigen in sera of patients with various cancers and infectious diseases were examined by an enzyme-linked immunosorbent assay (ELISA) and compared with those of healthy donors. The levels of antibody against TF antigen in sera of patients with adenocarcinomas such as gastric, pancreatic and colorectal cancers were lower than those of patients with hepatoma, pyelonephritis and pneumonia. These findings may reflect the expression of TF-antigen in adenocarcinoma tissues.

The expression of epithelial mucins and Thomsen-Friedenreich-related antigens in preneoplastic and neoplastic hepatocellular lesions was systematically investigated using an in situ immunohistochemical staining approach. MUC1, MUC2, TF, sialosyl-TF, Tn, sialosyl-Tn, alpha2,3-linked sialic acid, and alpha2,6-linked sialic acid were examined in normal and cirrhotic human liver and in human hepatocellular carcinomas (HCCs) and cholangiocarcinomas. Normal hepatocytes and preneoplastic foci of altered hepatocytes did not express MUC1, MUC2, TF, Tn, s-Tn, or alpha2,6-linked sialic acid. In contrast, HCCs showed positive reactions for MUC1, TF, Tn, s-Tn, and alpha2,6-linked sialic acid. MUC2 was absent in normal biliary epithelial cells, but present in cholangiocarcinomas. The staining of MUC1, or s-Tn and alpha2,6-linked sialic acid in human normal liver tissues and various liver diseases did not change after specific treatments such as periodate oxidation or saponification, indicating that their expression in HCC does not result from incomplete glycosylation or low O-acetylation, respectively. MUC1, TF, Tn, s-Tn, and alpha2,6-linked sialic acid may be useful as indicators of progression of HCC in tissue sections, and perhaps also as targets for diagnostic and therapeutic approaches in vivo.
