Clocking Salt Levels In The Blood: Link Between The Circadian Rhythm And Salt Balance

New research suggests a link between the circadian rhythm and control of sodium (salt) levels in the blood of mice. Specifically, the circadian clock protein Period 1 was found to function downstream of the hormone aldosterone (a known controller of blood sodium levels and thereby blood pressure) to regulate levels of the alpha-subunit of the epithelial sodium channel in the mouse kidney.
