Loss of heterozygosity on chromosome 1q in human breast cancer.
Cytogenetic markers involving the long arm of chromosome 1 are the most frequently observed karyotypic changes seen in breast cancer. Based on cytogenetic data, we have used polymorphic DNA markers to search for allelic losses at this chromosome region among 48 breast carcinomas. For SPTA1, allelic losses were seen in 6 of 26 (23%) informative carcinomas, while 3 of 13 (23%) and 5 of 19 (26%) i...
متن کاملLoss of maternal alleles on chromosome arm 11p in hepatoblastoma.
Hepatoblastoma is the most common primary malignant liver tumor in children, yet little is known about molecular genetic changes in these tumors. Previous studies report loss of heterozygosity on chromosome arm 11p in some hepatoblastomas. We used the polymerase chain reaction to amplify multiple microsatellites on chromosome arm 11p to assess loss of heterozygosity in 18 hepatoblastomas. Loss ...
متن کاملFrequent loss of heterozygosity on chromosome 14q in neuroblastoma.
Using 29 polymorphic DNA markers which detect allelic deletion of genes at specific loci on 19 different chromosomes, we analyzed 14 neuroblastomas for possible loss of chromosomal heterozygosity. The incidence of loss of heterozygosity was high at the D14S1 locus on chromosome 14q, being detected in six of 12 patients (50%). In spite of the cytogenetic finding suggesting high frequency of chro...
متن کاملLoss of heterozygosity on chromosome 11 q in breast cancer.
AIMS Chromosome 11q23 seems to be a site of frequent mutation in cancer. It also contains loci such as ataxia telangiectasia with possible importance in the pathogenesis of breast tumours. The short arm of chromosome 11 has been studied extensively in breast cancer, but the long arm, in particular the distal part, has been studied less frequently. Cytogenetic analysis has shown possible involve...
متن کاملLoss of heterozygosity of the BRCA1 and other loci on chromosome 17q in human prostate cancer.
A putative tumor suppressor gene, the BRCA1 gene, on chromosome 17q21 has recently been identified and shown to be mutated in breast and ovarian cancers. We have undertaken the present study to explore the possible involvement of the BRCA1 and/or other potential genes on chromosome 17q in prostate cancer. Twenty-three patients were screened by PCR for loss of heterozygosity at five microsatelli...
