title: Ganglioside variations in human liver cirrhosis and hepatocellular carcinoma as shown by two-dimensional thin-layer chromatography.
abstract: Gangliosides isolated from 5 cases of normal liver tissues, 11 cases of liver cirrhosis and 5 cases of hepatocellular carcinoma were compared in their concentrations and compositions. Quantitative analysis revealed no significant change of ganglioside levels between normal and cirrhotic liver tissues or hepatocellular carcinoma. There was also no significant difference (p greater than 0.05) between cirrhotic liver tissues and hepatocellular carcinoma. Two dimensional thin-layer chromatography of the total ganglioside preparations of liver tissues from both liver cirrhosis and hepatocellular carcinoma showed proliferation of GM2, GD3, GD1 and at least two unidentified components, named provisionally spots Nos. 1 and 2 in the present report, and loss of GM3. Sialidase treatment and thin-layer chromatography showed the components of these spots to be sialidase-labile monosialogangliosides and distinctly different from GD3 which was described elsewhere.
