    Abstract

    Using chromosome painting, a study of chromosomal abnormalities was performed in six gastric carcinoma cell lines (SNU-484, 601, 620, 638, 668, 719) from Korean patients. Each carcinoma cell line had unique modal karyotypic characteristics and showed a variable number of numerical and structural clonal cytogenetic aberrations. SNU-484, SNU-620, and SNU-668 had near-triploidy; SNU-601, SNU-638, and SNU-719 had near-diploidy. The origins of the marker chromosomes of these cell lines were identified by fluorescence in situ hybridization with constructed painting probes. In all of six cell lines, rearrangement of chromosome 17 resulting in partial deletion of 17p (and/or partial duplication of 17q) was found. The most frequent marker was a partial gain of chromosome 7 with the breakpoints on 7q22 and 7q31. The nonrandom rearrangements of chromosomes were also determined on 1q32, 5q11- q22, 8q, 14q22, 14q34, and 15q15; suggesting that they may be the candidate regions for the isolation of the genes related to gastric cancer.
