Abstract:Background. In addition to show autonomous beating rhythmicity, the physiological functions of the heart present daily periodic oscillations. Notably the ventricular repolarization itself varies throughout the circadian cycle which was mainly related to the periodic expression of K+ channels. However, the involvement of the L-type Ca2+ channel (CaV) 1.2 encoded by Cacna1c gene) in these circadian variations remains elusive. Methods. We used a transgenic mouse model (PCa-luc) that expresses the luciferase repor… Show more
