Carcinomas: A Possible Tumor Suppressor Gene at 7q31.1 Loss of Heterozygosity in Human Primary Prostate
نویسندگان
چکیده
We studied loss of heterozygosity (LOH) on human chromosome 7q to determine the location of a putative tumor suppressor gene (TSG) in human primaryprostatecarcinomas.Sampleswere obtainedfrom 16 primary prostate carcinomas surgically removed from patients at The University of Texas M. D. Anderson Cancer Center. Paired normal and tumorDNAswereusedas templatefor PCRamplificationof a set of 14 CA microsatellite repeats on 7q21-qter. Twelve of 16 cases studied had LOH at one or more loci on 7q. Eighty-threepercentLOH (five of six informative cases) was detected with D7S522 at 7q31.1—7q31.2. Percentage of LOH was normally distributed around D7S522. The high incidence of LOH in primary prostate carcinomas suggests that there is a TSG rele vant to the developmentof prostatecancersat 7q31.1—31.2, confirming our previous functional evidence for a TSG at this location. Further research needs to be conducted to establish the identity and function of this putative TSG.

Consistent deletions and loss of heterozygosity (LOH) in polymorphic markers in a determinate chromosomal fragment are known to be indicative of a closely mapping tumor suppressor gene. Deletion of the long arm of chromosome 7 is a frequent trait in many kinds of human primary tumors. We studied LOH of 14 markers on chromosome 7q in order to determine the location of a putative tumor suppressor...

The ST7 gene was cloned and mapped to chromosome 7q31.1-q31.2, a region suspected of containing a tumor suppressor gene involved in a variety of human cancers. Subsequent investigation described the presence of ST7 mutations in human cell lines derived from breast tumors and primary colon carcinoma. Introduction of the ST7 cDNA into a prostate cancer-derived cell line abrogated in vivo tumorige...
متن کاملFrequent loss of heterozygosity at 7q31.1 in primary prostate cancer is associated with tumor aggressiveness and progression.
Cytogenetic analyses have demonstrated that chromosome region 7q22-32 is commonly altered in prostate adenocarcinomas. In addition, in recent fluorescence in situ hybridization studies, we have observed that aneusomy of chromosome 7 is frequent in prostate cancer and is associated with higher tumor grade, advanced pathological stage, and early prostate cancer death. These findings suggest that ...
