Cardiac Atrial Circadian Rhythms in PERIOD2::LUCIFERASE and per1:luc Mice: Amplitude and Phase Responses to Glucocorticoid Signaling and Medium Treatment
Figure 6
Timing of the first peak in the bioluminescence rhythm in cultures of left and right atrium of PER2LUC mice.
The phases for individual cultures and mean ± SEM are shown. The phase is plotted as Zeitgeber time (ZT), based on the preceding light-dark cycle, where ZT0 = lights on and ZT12 = lights off.
