Purβ directly binds to the Adcy6 promoter and increases its transcription. (A) Nascent Adcy6 mRNA levels were measured by nuclear run-on RT-qPCR in Purβ-overexpressing hepatocytes (n = 3). (B) ChIP assays showing Purβ occupancy at the promoter of Adcy6 (n = 3). (C) Mouse Adcy6 promoter (−2001 to −1 or −1001 to −1) luciferase reporter plasmids and β-galactosidase reporter plasmids were transiently cotransfected with Purβ expression plasmids into HEK293T cells. Luciferase activity was measured 24 h after transfection and normalized to βGal levels (n = 6). *p < 0.05. **p < 0.01.
