title: Application of CARD-ISH for Assessment of Numerical Chromosome Aberrations in Interphase Nuclei of Human Tumor Cells.
abstract: In this study based on the study of a centromeric DNA probe specific for chromosome 8 the authors standardized a method for the enzymatic detection of specific chromosome copy numbers on interphase nuclei from tumor tissue samples. Since the in situ hybridization (ISH) of chromosome 8 specific probe was revealed with a catalyzed reporter deposition (CARD), which allows a high amplification of the hybridization signal, the method was designated as CARD-ISH. This method has been standardized on interphase nuclei isolated from clinical samples of pituitary adenomas, as well as on human normal lymphocytes. On the same samples, they also evaluated chromosome 8 copy number distribution by FISH. Comparison between CARD-ISH and FISH results showed no significant differences between the two methods, proposing CARD-ISH as a reliable alternative to FISH for chromosome numerical aberration assessment in laboratories that do not have specific facilities for epifluorescence microscopy or cytogenetics and that need a long-term storage of slides that had been used for diagnostic purposes.
