Mitochondrial Problems May Link Night Shift Work’s Disrupted Body Clock to Higher Blood Pressure in Humans and Mice

Abstract

Circadian rhythm disruption from night-shift work is associated with elevated blood pressure in both mice and humans.

  • Simulated night shift work in mice results in increased blood pressure and mitochondrial dysfunction.
  • Circadian gene dysregulation, such as alterations in PER1 and BMAL1, occurs in response to night shift work.
  • In human night shift workers, longer exposure duration correlates with higher systolic and diastolic blood pressure.
  • Dysregulation of circadian and mitochondrial markers is observed alongside increased blood pressure in humans.
  • Mitochondrial dysfunction may be a key mechanism linking circadian disruption to elevated blood pressure.
