Abstract

The precise mechanisms of blood pressure (BP) regulation are not fully elucidated, and understanding BP regulation is crucial for managing hypertension and improving outcomes for cardiovascular disease. In this issue of the JCI, Wang et al. identified the transcription factor PR domain–containing protein 16 (PRDM16) as a regulator of both vascular smooth muscle cell contraction and the circadian response to BP control. PRDM16 directly transcriptionally controlled the expression of the adrenergic receptor α 1d and several clock genes crucial for BP circadian regulation. These findings identify a mechanism of how molecular pathways govern circadian BP variation, highlighting PRDM16 as a potential target for hypertension.
