title: Identification of chromosomal structural alterations in human ovarian carcinoma cells using combined GTG-banding and repetitive fluorescence in situ hybridization (FISH).
abstract: In order to identify chromosomal structural alterations in the ovarian carcinoma cell line MLS/P, fluorescence in situ hybridization with centromeric probes for chromosomes 1, 8, 9, 13/21, 14/22, 15, 17, and X and whole chromosome painting probes for chromosomes 1, 3, 4, 5, 7, 8, 9, 10, 12, 13, 14, 17, 19, 22, and X were performed subsequent to GTG-banding. This combined approach identified 14 of the 18 clonal structurally rearranged chromosomes, with the X chromosome involved in three aberrations. In contrast, only eight of the 14 rearrangements were identifiable by G-banding alone. These results indicate that the combined G-banding and FISH approach can significantly improve the cytogenetic analysis of human neoplasia.
