Somatic copy number alterations associated with populations and clinical characteristics in ovarian clear cell adenocarcinoma

ABSTRACT: Background: Clinical characteristics of ovarian clear cell adenocarcinoma (CCC) include 1) higher incidence among Japanese, 2) association with endometriosis, 3) poor prognosis in advanced stage, 4) higher incidence of thrombosis as complication. We applied high resolution comparative genomic hybridization (CGH) array to screen somatic copy number alterations (SCNAs) associated with these clinical characteristics. Methods: We conducted a prospective cohort study. DNA obtained from tumors was assayed by array comparative genomic hybridization using Agilent Whole Human Genome 244K.

Somatic copy number alterations associated with populations and clinical characteristics in ovarian clear cell adenocarcinoma

Project description:Background: Clinical characteristics of ovarian clear cell adenocarcinoma (CCC) include 1) higher incidence among Japanese, 2) association with endometriosis, 3) poor prognosis in advanced stage, 4) higher incidence of thrombosis as complication. We applied high resolution comparative genomic hybridization (CGH) array to screen somatic copy number alterations (SCNAs) associated with these clinical characteristics. Methods: We conducted a prospective cohort study. DNA obtained from tumors was assayed by array comparative genomic hybridization using Agilent Whole Human Genome 244K. 117 tumor samples were analyzed by Agilent-G4411B Human Genome CGH Microarray Kit 244A. Log2 Ratio (tumor sample DNA/normal DNA) were compared between Japanese and non-Japanese, between patients with thrombosis and without thrombosis, between patients with endometriosis and without endometriosis, among patients sensitive to, intermediate to and resistant to the chemotherapy, among FIGO stages, between relapsed and not relapsed, between survived and not survived.

Genomic profiling of gastric adenomas by array-based comparative genomic hybridization

Project description:In this study, we investigated CNAs of 20 gastric CIS (Vienna category 4.2) and 20 adenomas, including 7 low-grade adenomas (LGA; Vienna category 3) and 13 high-grade adenomas (HGA; Vienna category 4.1), by 244k oligonucleotide-based array comparative genomic hybridization (array CGH).

Agilent 244K aCGH data for 10 human gastric cancers

Project description:Copy number alteration (CNA) is a good signpost to identify cancer related genes. CNAs were analyzed using the Agilent 244K array comparative genomic hybridization (aCGH) in fresh-frozen tumor and matched normal tissues from 10 gastric cancer patients.

Genomic profiling of chondrosarcoma: chromosomal patterns in central and peripheral tumors (BAC/CGH)

Project description:DNA copy number analysis of 67 fresh frozen chondrosarcoma biopsies using 32k BAC and 244k oligo array CGH. Genomic imbalances, in most tumors affecting large regions of the genome, were found in 90% of the cases. Although rare, recurrent amplifications were found at 8q24.21-q24.22 and 11q22.1-q22.3, and homozygous deletions of loci previously implicated in chondrosarcoma development affected the CDKN2A, EXT1 and EXT2 genes. Keywords: chondrosarcoma, array comparative genomic hybridization

Implication of Nos2 inactivation on genomic changes in Ptch1+/- medulloblastomas (array-CGH)

Project description:The Ptch1+/- strain constitues an established mouse model for the Shh-driven type of medulloblastoma. Combined Ptch1+/- Nos2-/- mice show a two-fold increased incidence for this tumor. Here, the impact of Nos2 inactivation on copy number alterations during medulloblastoma development was investigated by array-based comparative genomic hybridization (arrayCGH) of tumor samples from both genotypes.

Genomic profiles of oxidative stress-induced rat renal cell carcinomas

Project description:Intraperitoneal administration of ferric nitrilotriacetate (Fe-NTA) initiates Fenton reaction in the renal proximal tubules of rodents that ultimately leads to a high incidence of renal cell carcinoma (RCC) after repeated treatment. We performed high-resolution microarray comparative genomic hybridization to identify characteristics in the genomic profiles of oxidative stress-induced rat RCCs. The results revealed extensive large-scale genomic alterations with a preference for deletion.
