Conventional ChIP and RT-PCR analysis of selected C/EBPδ ChIP-chip target genes. a. C/EBPδ ChIP-chip target gene promoters. C/EBPδ target gene promoters are shown with gene-specific primers (→) and computer predicted C/EBP consensus sites (▶) Gene-specific human primer pairs are presented in Table 2. b. Conventional ChIP assays. Whole cell lysates were isolated from MCF-12A cells transfected with pCDNA3.1-hC/EBPδ-v5 and growth arrested by contact inhibition. Conventional ChIP assays performed with anti-v5 and IgG (negative control) antibodies. Input lane is derived from direct PCR amplification of genomic DNA. c. C/EBPδ target gene expression: RT-PCR analysis. Total RNA was isolated from MCF-12A cells transfected with pCDNA3.1-hC/EBPδ-v5 and cultured under exponentially growing (GR) or contact inhibition conditions. Total RNA was reverse transcribed and PCR amplified using gene-specific primers. No RT = PCR amplification of RNA samples without RT. GAPDH was used as a non-C/EBPδ inducible RNA expression control.
