High-resolution mapping of mammalian genes by in situ hybridization to free chromatin.

Investigation of TEL/AML1 and BCR/ABL Fusion Genes in Patients Affected by Acute Lymphoblastic Leukaemia Using Interphase in situ Hybridization

MINIREVIEW / MINISYNTHÈSE Current status and the future of fluorescence in situ hybridization (FISH) in plant genome research

Fluorescence in situ hybridization (FISH), which allows direct mapping of DNA sequences on chromosomes, has become the most important technique in plant molecular cytogenetics research. Repetitive DNA sequence can generate unique FISH patterns on individual chromosomes for karyotyping and phylogenetic analysis. FISH on meiotic pachytene chromosomes coupled with digital imaging systems has becom...

Intermingling of Chromosome Territories in Interphase Suggests Role in Translocations and Transcription-Dependent Associations

After mitosis, mammalian chromosomes partially decondense to occupy distinct territories in the cell nucleus. Current models propose that territories are separated by an interchromatin domain, rich in soluble nuclear machinery, where only rare interchromosomal interactions can occur via extended chromatin loops. In contrast, recent evidence for chromatin mobility and high frequency of chromosom...

Sensitive, high-resolution chromatin and chromosome mapping in situ: presence and orientation of two closely integrated copies of EBV in a lymphoma line.

Here we describe development and application of highly sensitive fluorescence methodology for localization of single-copy sequences in interphase nuclei and metaphase chromosomes by nonisotopic in situ hybridization. Application of this methodology to the investigation of Epstein-Barr virus integration in the Namalwa lymphoma cell line has revealed two EBV genomes closely integrated at the know...
