High and low chromosomal instability phenotypes in stage II and III colorectal cancers

Analysis of specimens from consecutive stage II and stage III colorectal cancer (CRC) patients with high or low chromosomal instability (CIN) phenotype. CIN-high CRC showed poorer outcome than CIN-low CRC. Results provide insight into molecular biomarkers to distinguish between the CIN phenotypes.

A new classification of chromosome instability (CIN) phynotype, CIN-high and CIN-low (validation dataset)

(Submitter supplied) Samples were taken from colorectal cancers in surgically resected specimens in 33 colorectal cancer patients. The expression profiles were determined using Affymetrix Human Genome U133 Plus 2.0 arrays. Comparison between the sample groups allow to identify a set of discriminating genes that can be used for molecular markers for CIN phynotype

Chromosome copy number and LOH analysis of colorectal carcinoma specimens

(Submitter supplied) Structural changes of chromosomes play important roles in the carcinogenesis of colorectal carcinoma (CRC). Here, by using SNP-typing arrays, we have tried to screen for recurrent chromosome copy number changes and loss-of-heterozygosity in the genome of colorectal carcinoma. Genomic DNA was isolated from tumor and paired normal tissues of CRC (n=94), and was hybridized to Affymetrix Mapping 50K Xba 240 arrays. more...

SNP arrays in matched colorectal cancer and normal colonic mucosa.

(Submitter supplied) We analyzed, by last-generation high-resolution SNP arrays, colorectal adenocarcinoma samples and matched normal colonic tissues in order to determine the number of tumor-associated copy number abnormalities (CNAs) and copy neutral-loss of heterozygosity (CN-LOH) regions per patient and to identify possible recurring genomic abnormalities.
