MYC occupies the ITGA1 promoter. (a) ChIP assay with an anti-human c-Myc-specific antibody or with a Pol-II antibody was performed in HT29 cells and real-time quantitative PCR (qPCR) amplification products were migrated on gel. Mock immunoprecipitation with mouse anti-IgG was performed as negative control. (b) Enrichment of the ITGA1 promoter region containing the MYC response elements was calculated by PCR quantification relative to the amount of control chromatin without response element for MYC. (c) Enrichment for the CCND1 promoter containing one complete EBOX response element was used as a positive control. Results represent the mean of three independent experiments, with qPCR performed in triplicate. *P<0.05, **P<0.01.
