Our genome wide approach by chromatin immunoprecipitation sequencing (ChIP-seq) in human colorectal cancer cells identified a number of physiological targets of SOX9, including ubiquitously expressed cell cycle regulatory genes, such as CCNB1 and CCNB2, CDK1, and TOP2A. These novel high affinity-SOX9 binding peaks precisely overlapped with binding sites for histone-fold NF-Y transcription factor. The gene discussed is CCNB1; the disease is colorectal cancer.
