TI - Detection of CDKN2 deletions in tumor cell lines and primary glioma by interphase
fluorescence in situ hybridization.
PG - 984-8
AB - Deletions of chromosomal band 9p21 have been detected in various tumor types
including melanoma, glioma, lung cancer, mesothelioma, and bladder cancer.
Recently, the CDKN2 gene (p16INK4A, MTS I, CDK41) has been proposed as a
candidate tumor suppressor gene because it is frequently deleted in cell lines
derived from multiple tumor types. We performed fluorescence in situ
hybridization (FISH) with interphase cells using yeast artificial chromosome
clones and a cosmid contig of the CDKN2 region. In 10 cell lines (4 glioma, 2
melanoma, 2 non-small cell lung cancer, 2 bladder cancer) with 9p alterations
detected by molecular or cytogenetic analysis, interphase FISH with the CDKN2
cosmid contig detected all 9p deletions previously identified by molecular
analysis. Using this probe, FISH analysis of primary glioblastoma tumors revealed
homozygous deletions of the CDKN2 region in 6 of 9 tumors (67%) whereas a yeast
artificial chromosome probe containing the interferon type I (IFN) gene cluster
was deleted in only 4 cases (44%). Thus, it is likely that the CDKN2 region is
the target of 9p deletions in gliomas. Interphase FISH will play an important
role in defining the clinical significance of 9p deletions in primary tumors
because it is especially applicable to clinical samples which may be contaminated
by normal cells.
