Imbalances of chromosome 17 in medulloblastomas determined by comparative genomic hybridisation and fluorescence in situ hybridisation.
AIMS To investigate the status of chromosome 17 in a series of medulloblastomas using comparative genomic hybridisation (CGH) and fluorescence in situ hybridisation (FISH). METHODS Frozen tissue and formalin fixed, paraffin was embedded tissue from 27 medulloblastomas were analysed by CGH and FISH, respectively. CGH ratio profiles for chromosome 17 were compared with the results of FISH, for ...
متن کاملA non-isotopic in situ hybridisation study of the chromosomal origin of 15 supernumerary marker chromosomes in man.
Fifteen patients presenting with mosaic or non-mosaic karyotypes containing a distamycin-DAPI negative de novo or familial supernumerary marker chromosome were studied with non-isotopic in situ hybridisation using a library of alphoid centromere specific and satellite II/III probes. The in situ hybridisation studies showed that seven markers were derived from satellited autosomes (three chromos...
متن کاملIdentification and characterisation of a small marker chromosome using non-isotopic in situ hybridisation with X and Y specific probes.
A 13 year old male with mild mental retardation, obesity, and poor secondary sexual differentiation was found to have a 46,X,+,mar karyotype. In situ hybridisation with X and Y specific probes proved the marker to be composed of Y centromeric and short arm material.
متن کاملFeasibility of in situ hybridisation with chromosome specific DNA probes on paraffin wax embedded tissue.
The feasibility was studied of in situ hybridisation using chromosome specific DNA probes on paraffin wax embedded normal and malignant tissues from different organs. Both isolated nuclei and 5 microns sections were used in in situ hybridisation experiments with biotinylated repetitive DNA probes specific for the centromeric regions of chromosomes 1 and 17. The hybridisation results were visual...
متن کاملChromosome in situ suppression hybridisation in human male meiosis.
Chromosome in situ suppression hybridisation with biotinylated whole chromosome libraries permits the unequivocable identification of specific human somatic chromosomes in numerous situations. We have now used this so called 'chromosome painting' technique in meiotically dividing cells, isolated from human testicular biopsy. It is shown that the method allows identification of target homologues...
