Title Detection of aberrant DNA methylation in colorectal carcinoma samples compared to normal human colon
Organism Homo sapiens
Experiment type Methylation profiling by genome tiling array
Genome variation profiling by genome tiling array
Summary To globally define methylation-’prone’ and -’protected’ CpG islands in colorectal carcinoma we analyzed the methylation status of 23,000 CpG islands of the human genome in ten coleorectal carcinoma samples as well as normal colon using our previously described methyl-CpG immunoprecipitation (MCIp) technique (Gebhard et al. 2006; Schilling and Rehli 2007). This method enriches for highly CpG methylated DNA that can be directly applied to fluorescent labeling and oligonucleotide microarray hybridization without an additional amplification step.

Keywords: MCIp-on-Chip; comparative genomic hybridization
 
Overall design CpG-methylated genomic DNA was enriched using methyl-CpG immunoprecipitation (MCIp). On each microarray, the enriched material from colorectal carcinoma samples was compared to the enriched material from normal colon to identify aberrantly methylated regions.
