PG - 372-7 AB - We performed detailed molecular analyses of a suspected homozygous deletion on chromosome 9q32-q33 in a bladder-cancer cell line (KYBTDS) derived from a superficial papillary transitional cell carcinoma (TCC). We examined 13 sequence-tagged site (STS) markers mapped along 9q32-q33 by polymerase chain reaction (PCR), and used 13 bacterial artificial chromosome (BAC)/bacteriophage P1-derived artificial chromosome (PAC) genomic clone probes representing these STS markers as probes for dual-color fluorescence in situ hybridization (FISH) analyses to define the deleted region cytogenetically and at the molecular level. Southern blotting confirmed the findings. This combination of techniques revealed that the homozygous deletion in the KYBTDS cell line involved less than 1 megabase of DNA, flanked by markers A003P42 and SGC33380. This interval overlaps part of a common region of deletion observed in a number of primary bladder cancers; moreover, the DNA sequence within the 1-Mb segment corresponds to part of a YAC genomic clone that encompasses a putative tumor suppressor gene, DBCCR1.
