Abstract
DNA aberrations in human hepatocellular carcinoma (HCC) were studied by two-dimensional DNA electrophoresis analysis. Five intensified and 60 dwindling spots were detected recurrently in the two-dimensional profile which showed about 3000 restriction DNA fragments as distinctive spots. We assigned these aberrant spots to chromosomes, using the chromosome-assigned two-dimensional profile. Four of the five intensified, and 53 of the 60 dwindling spots were given chromosome assignments. Intensified spots were assigned to chromosomes 5, 6, 9 through 12, 16 and 18. Among the dwindling spots, the highest incidence of aberrations was found on chromosome 16, followed by 9 through 12 and chromosome 2. No aberrations were detected in chromosomes 7, 21, 22 or Y.
