Abstract

PURPOSE: The characterization of all recognizable chromosomal rearrangements was dis- turbed by technical limitation of conventional cytogenetic methods. Recently, the strong usefullness of generation of chromosome specific painting probes in identification of marker chromosomes has proven. This study was intended to analyze the chromosomal aberrations in human ovarian cancer cell line, SNU-8, by G-banding and multiple paintings.
MATERIALS AND METHODS
Human ovarian cancer cell line, SNU-8 was cultured and harvested for cytogenetic analysis. Routine karyotyping was performed. For complete analysis of chromosomal aberrations, human chromosome-specific painting probes were constructed from somatic hybrid cells. The origins of the unidentified marker chromosomes were analyzed by fluorescent in situ hybridization (FISH) with these painting probes.
RESULTS
All chromosome alterations were confirmed by the use of multiple chromosome paintings, which also demonstrated a number of additional alterations. SNU-8 had the karyotype 62-69,XXX, + der(1;10)(q10;p10),der(3;18) (q10;p10)X2,-4,+ 5,+ 7,del(9)(q21)X2,-11,-13,-15,-16,der(17;19)(q10;q10) X2, + 20,-22[cp51].
CONCLUSION
The chromosomal aberrations of SNU-8 cell line was effectively analyzed by FISH with these painting probes, and the approach methods of this study can be applied to cytogenetic analysis of chromosomal aberrations in the other cancers.
