Loss of heterozygosity (LOH) of chromosomal regions is crucial in tumor progression. In this study we assessed the potential of the Affymetrix GeneChip HuSNP mapping assay for detecting genome-wide LOH in prostate tumors. We analyzed two human prostate cell lines, P69SV40Tag (P69) and its tumorigenic subline, M12, and 11 prostate cancer cases. The Ml 2 cells showed LOH in chromosomes 3p12.1-p22.I, 1lq22.1-q24.2, 19p13.12, and 19ql 3,42. All of the prostate cases with informative single-nucleotide polymorphism (SNP) markers showed LOH in lpi31.2, 10ql1.21, 12p13,1, 16q23.1-q23.2, 17p13.3, 17q21,31, and 21q21.2. Additionally, a high percentage of cases showed LOH at 6p25,1-p25.3 (75%), 8p22-p23.2, and 10q22.1 (70% Several tumor suppressor genes (TSGs) have been mapped in these loci. These results demonstrate that the HuSNP mapping assay can serve as an alternative to comparative genomic hybridization for assessing genome-wide LOH and can identify chromosomal regions harboring candidate TSGs implicated in prostate cancer.
