Project description:In order to investigate the chromosomal alterations (gains or losses) of tumor tissuees developed in TH-MYCN mice, a neuroblastoma model, we carried out array comparative genomic hybridization. We investigated whether chromosomal alterations occured in the tumor tissues developed in the abdomen of TH-MYCN hemizygote mice.
Project description:It has been already reported that there are undifferentiated/proliferating neuroblasts in the postnatal sympathetic ganglia in TH-MYCN mice, a neuroblastoma model. We established suitable spheroid culture condition that selectively isolates undifferentiated neuroblasts from superior mesenteric ganligon (SMG) of TH-MYCN mice. In order to investigate the chromosomal alterations (gains or losses) of spheres derived from TH-MYCN mice, we carried out array comparative genomic hybridization. We investigated whether chromosomal alterations occured during early neuroblastoma tumorigenesis in TH-MYCN mice.
Project description:Somatic copy number alterations of 17 paired tumor and metastasis tissue samples were measured by Agilent array-based comparative genomic hybridization (CGH). Seven colon adenocarcinomas with paired liver metastasis and 10 liver carcinoma with metastasis to the lymph node, adrenal gland or lung were analyzed.
Project description:In this study, 19 tumor samples from patients with renal cell carcinoma (RCC)-end-stage renal disease (ESRD) were analyzed by array comparative genomic hybridization (array CGH) using the Agilent Whole Human Genome 4× Array.
Project description:In this study, eighty tumor samples from 63 patients with renal cell carcinoma (RCC)-end-stage renal disease (ESRD) were analyzed by array comparative genomic hybridization (array CGH) using the Agilent Whole Human Genome 4×44K Oligo Micro Array.
Project description:Copy number alteration (CNA) is a good signpost to identify cancer related genes. CNAs were analyzed using the Agilent 400K array comparative genomic hybridization (aCGH) in fresh-frozen tumor and matched normal tissues from 30 gastric cancer patients.
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.
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.
