Loss of chromosome 8p sequences in human breast carcinoma cell lines.
Journal Article
Cytogenetic and molecular analyses of human breast cancer cells have identified consistent losses of specific chromosomal regions in these tumors, suggesting that such regions harbor tumor suppressor genes whose homozygous loss or inactivation directly contributes to tumorigenesis. To date, deletions of chromosome 8 sequences have been described infrequently and only in low percentages of breast carcinomas. We report the identification of a new DNA marker on chromosome 8p that is deleted in 6 (75%) of 8 breast carcinoma cell lines and in 1 primary breast carcinoma examined. No deletion of this marker was detected in any normal or nonbreast carcinoma cell lines analyzed. Southern blot and fluorescence in situ hybridization studies indicate that this clone maps to chromosome 8 between bands p12 and p21. These observations suggest that a new gene, whose loss or inactivation may foster breast carcinoma tumorigenesis, may reside in this chromosome 8p region.
