Figure 2. c-Myc regulates CE recruitment to c-Myc target genes.
(A) HeLa cells transfected with c-Myc siRNA or a non-targeting control for 24 hours were analysed by Western blotting. (B) c-Myc target genes transcript level, normalised to GAPDH, were determined by RT-qPCR in HeLa cells transfected with c-Myc siRNA or non-targeting control for 48-72 hours. Error bars represent standard error of the mean, n≥3. (C) Chromatin immunoprecipitation assay (ChIP) was performed using anti-CE antibody or control, in HeLa cells transfected with c-Myc siRNA or non-targeting control for 24 hours. c-Myc target genes (NCL, FBL and NME1), and GAPDH in ChIPs were analysed by qPCR. CE ChIP signal was expressed as fold enrichment over control ChIP signal. Schematics depict regions of primer amplification relative to the TSS (arrow) and E-box sequence(s) (bold band). Error bars represent standard error of the mean, n≥3. Significance calculated by Student's T-test; * = p≤0.05, ** = p≤0.01, *** = p≤0.001.
