Abstract
1. 1. Twenty perchloric acid-soluble glycoprotein fractions (PASFs) were separated from carcinomatous and non-carcinomatous regions of the livers of 5 patients with primary hepatocellular carcinoma (HCC) and 5 patients with a complication of HCC and hepatocirrhosis (HC). 2. 2. In autoradiography using 125,I-labelled Vicia unijuga lectin (VUA) and 125I-labelled Arachis hypogaea anti-T lectin as probes, 10 PASFs from carcinomatous regions of the livers of 10 patients gave 1 Vgu glycoprotein with T activity and/or 1–4 Vgu glycoproteins, respectively, and among 10 PASFs from non-carcinomatous regions of the livers of 10 patients, 7 PASFs gave no glycoproteins, respectively. li ]3. These results show that a Vgu glycoprotein with T activity and Vgu glycoproteins occur in HCC and in a complication of HCC and HC as oncofetal antigens.
