Research Abstract |
Blood pressure shows a circadian variation, and many patients with cardiovascular diseases show disturbance in blood pressure circadian rhythm. We found that clock protein DEC1 binds and represses the E-boxes in the promoter of Atp1b1 gene, which encodes the beta subunit of Na/K-ATPase, whereas CLOCK activates these E-boxes. Consequently, the Atp1b1 mRNA and protein levels in the cardiovascular system showed circadian rhythms. Dec1-deficient mice showed decreased blood pressure, whereas clock-mutant mice showed increased blood pressure, as Na/K-ATPase is essential for the control of blood pressure. These findings revealed for the first time the molecular mechanism involved in blood pressure circadian rhythm.
