title: Cytogenetic analysis of BC2, a new human hepatoma cell line, by fluorescent in situ hybridization.
abstract: Cytogenetic analysis of a new human hepatoma cell line BC2 was performed with conventional cytogenetic techniques and fluorescent in situ hybridization. Numerical and structural abnormalities were observed by conventional cytogenetics for chromosomes 1, 2, 4, 7, 8, 9, 10, 11, 15, 17 and 20. Chromosome painting allowed to specify the translocation of chromosome 1, and to characterize 3 markers from chromosome 8 and one marker from 9, which were unrecognizable by conventional techniques. Comparison of chromosome 1 abnormalities with those reported in the literature for other human hepatoma cell lines showed that structural abnormalities of chromosome 1 were present in different regions of this chromosome. A review of the literature was done, and the results discussed, suggesting that alterations of chromosome 1 may be important in hepatocarcinogenesis.
