Several somatic genetic alterations have been described in colorectal carcinoma (CRC). Recurrent chromosomal deletions have suggested the presence of tumor suppressor genes (TSG) specifically involved in colorectal carcinogenesis. For one of them, two non-overlapping regions have been proposed on th

Abstract
Loss of the short arm of chromosome 8 is a common event in prostatic neoplasms. Previous studies indicate that there may be up to three separate tumor suppressor genes on chromosome arm 8p, based on patterns of allelic loss. The responsible gene or genes have yet to be identified. In the present study, we used laserβcapture microdissection of primary human prostate tumors and 17 microsatellite markers across chromosome band 8p21 to determine a minimal deletion interval. From an initial set of 120 cases, three tumors contained overlapping interstitial deletions on chromosome band 8p21. The three cases define an internally consistent minimal candidate tumor suppressor gene interval of approximately two megabases. Published 2002 WileyβLiss, Inc.

One of the most frequent genetic abnormalities in prostate cancer is loss of the complete or part of the short arm of chromosome 8, indicating the localization of one or more tumor suppressor genes on this chromosomal arm. Using allelotyping, a frequently deleted region in prostate cancer in a genet
Chromosome 9p has been reported to be a critical region of loss in various cancers. Our present study was designed to determine the frequency of deletions at different loci of chromosome 9p in microdissected samples of normal prostatic epithelium and carcinoma from the same patients. For this purpos
Chromosome 6 has been shown to contain at band q27 a minimal region of deletion associated with epithelial ovarian cancers and AF6, a gene disrupted in acute myeloid leukemia with t(6;l l)(q27;q23). Using rapid amplification of cDNA ends by polymerase chain reaction, the breakpoint in AF6 was confir
Loss of heterozygosity (LOH) on 3p is frequent in human renal cell carcinomas, lung cancers, and breast cancers. To define the region(s) on 3p that harbor presumptive tumor suppressor gene(s) for breast cancer, we examined 196 primary breast tumors for their patterns of LOH at 22 microsatellite mark
