The lectin binding characteristics of spontaneous and phenobarbitone induced hepatic lesions in C3H/He mice.
The surface membrane glycoprotein patterns of spontaneous hepatic nodules, phenobarbitone induced nodules and hepatocellular carcinoma were studied in the C3H mouse using lectin histochemistry. The lectin binding patterns of hepatocellular carcinoma cells were markedly different to those of non-tumour cells and similar to the pattern in chemically induced hepatocellular carcinomas. This supports the hypothesis that changes in surface glycoprotein are a consistent feature associated with malignancy. Similar changes in the distribution of lectin binding sites were also seen in the phenobarbitone induced eosinophilic nodules and in a proportion of spontaneous basophilic nodules. Two populations of early basophilic nodules were identified on the basis of their lectin binding patterns, and this may indicate a link between one nodular type and carcinoma.
