Allelic Loss and Microsatellite Instability in Prostate Cancers in Japan
A series of 25 primary prostate cancers in Japanese were screened for loss of heterozygosity and microsatellite instability using twelve microsatellite markers containing APC, DCC, TP53, BRCA1, and BRCA2. Frequent loss of heterozygosity was observed for D8S201 (48%), LPL (48%), and DCC (26%). In con...

Zusammenfassung: | A series of 25 primary prostate cancers in Japanese were screened for loss of heterozygosity and microsatellite instability using twelve microsatellite markers containing APC, DCC, TP53, BRCA1, and BRCA2. Frequent loss of heterozygosity was observed for D8S201 (48%), LPL (48%), and DCC (26%). In contrast, the incidence did not exceed 15% at BRCA1 and BRCA2 loci. Microsatellite instability was observed in 28% of stage B, C, and D cancers. These data suggest that microsatellite instability and loss of unidentified genes on chromosome 8p may be involved in carcinogenesis of the prostate; however, BRCA1 and BRCA2 may not be largely involved in the development of prostate cancer in the Japanese population. |
