Representational difference analysis (RDA) of a human glioblastoma xenograft resulted in the isolation of five tumour-associated homozygously deleted DNA fragments, all originating from chromosome 9, region p21. Subsequent analysis of a series of ten glioblastomas using the newly isolated RDA fragme

โฆ Synopsis
Thirty-nine recombinants isolated from a Y chromosome-specific library were deletion mapped. Seven deletion intervals were defined by hybridization of probes to DNA of eight individuals with aberrant Y chromosomes. Extreme cytogenetic limits of the deletion intervals were determined by in situ hybridization of one probe per deletion interval. Five intervals, with a total of twenty-five probes, were allocated to the longarm euchromatic region. The probes described will be useful for characterization of aberrant Y chromosomes, in searching for expressed sequences on the Y chromosome, and for further study of the evolutionary relationship between the Y chromosome and other chromosomes.
