Chromosome Deletion Patterns in Prostate Cancer
Various nonrandom chromosomal aberrations have been identified in prostate carcinoma. These aberrations include deletions of several chromosome regions, particularly the chromosome 8 short arm. Large-scale numerical aberrations, reflected in aberrant DNA ploidy, are also found in a minority of cases. However, it is unclear whetherprostate carcinomas contain aberrations of certain chromosome reg...
متن کاملanalysis of candidate genes has proposed the role of y chromosome in human prostate cancer
background prostate cancer is a serious genetic disease known as the first widespread cancer in men, yet the molecular changes required for the cancer progression is not fully understood. availability of high-throughput gene expression data has led to the development of various computational methods for the identification of critical genes involved in the cancer. methods in this paper, we show ...
متن کاملHuman colorectal cancer: high frequency of deletions at chromosome 1p35.
Cytogenetic analyses of human colon cancer cells have revealed a high frequency of chromosome 1p deletions among other chromosomal abnormalities. In order to find out whether these chromosomal alterations are manifestations of loss of genetic material, we surveyed DNA of 62 primary tumors, 7 metastases, and matching peripheral blood cells with a panel of polymorphic DNA probes that detect diffe...
متن کاملHomozygous deletion and frequent allelic loss of chromosome 8p22 loci in human prostate cancer.
Allelic loss studies have been instrumental in identifying tumor suppressor gene loci in a variety of cancers. In this study we analyzed prostate cancer specimens from 52 patients for allelic loss using 8 polymorphic probes for the short arm of chromosome 8. Overall, 32 of 51 (63%) informative tumors showed loss of at least one locus on chromosome 8p. The most frequently deleted region is obser...
متن کاملPrevalence of Human Cytomegalovirus Infection in Iranian Prostate Cancer Patients
Background and Aim: Human cytomegalovirus (HCMV) has the potential for oncogenicity and has been associated with many malignancies, including prostate cancer. This study aimed to investigate the genomic prevalence of HCMV in prostate cancer tumors. Materials and Methods: In this case-control study, 31 patients with prostate cancer were enrolled along with 31 patients with benign prostate cance...
