Effects of propofol on mammalian central and peripheral circadian clocks [post]

2019 unpublished
Circadian rhythm has a significant correlation with the occurrence and development of many diseases. Studies have shown that the anesthetic agent propofol can alter the rhythms of body temperature and activity in rats. Methods U2OS cells and ex vivo liver tissue were treated with different concentration of propofol, followed by recording the oscillation of the circadian clock. And two month-old mice were exposed to propofol (10mg/kg and 20mg/kg) or vehicle, detecting the expression of the clock

Treatment with 10 mg/kg propofol significantly increased the expression of D-box binding PAR BZIP transcription factor (Dbp) and clock circadian regulator
