Fig. 4. ZNF276 regulates CYP1B1 promoter transcriptional activity.

Fig. 4

A The mRNA levels of the 15 genes with relative high fold change were verified by RT-qPCR. B The effect of ZNF276 knockdown on the mRNA expression of CYP1B1. C Western blot analysis of the effect of ZNF276 overexpression and knockdown on CYP1B1 expression. D Dual-luciferase reporter gene assay showing ZNF276 overexpression promoted luciferase activity of CYP1B1 promoter. E Dual-luciferase reporter gene assay showing inhibition of ZNF276 decreased luciferase activity of CYP1B1 promoter. F Construction of truncated fragments of ZNF276 for investigating the binding site of ZNF276 on CYP1B1 promoter. G Dual-luciferase reporter gene assay measuring the CYP1B1 promoter luciferase activity driven by different truncated fragment of ZNF276. H Construction of truncated fragments of CYP1B1 promoter for investigating the ZNF276 binding site. I Dual-luciferase reporter gene assay measuring the truncated CYP1B1 promoter luciferase activity in ZNF276 overexpressing and control cells. J ChIP-PCR assay demonstrated a direct binding of ZNF276 at the CYP1B1 promoter. *p < 0.05; **p < 0.01; ***p < 0.001.
