ChIP-Seq of Transcriptional Components in Colon carcinoma. Homo sapiens

Discovery of the genome-wide location of proteins using ChIP-Seq has allowed global mapping of the key transcription factors and chromatin regulators that control gene expression programs in various cells. Many DNA-associated processes are targeted for disease therapy. CDK8 is a kinase component of the Mediator co-activator complex and is often over-expressed in colorectal cancer. This study investigates the genome-wide localization of CDK8 in human colorectal cancer cells. Overall design: Genomic DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. ChIP was performed using an antibody against H3K27ac and CDK8 as well as whole-cell extract (WCE) DNA controls.
