Circadian governance of cardiac growth
WebApr 19, 2024 · Circadian clocks are intracellular molecular mechanisms that allow the cell to anticipate the time of day. We have previously reported that the intact rat heart expresses the major components of the circadian clock, of which its rhythmic expression in vivo is consistent with the operation of a fully functional clock mechanism. The present study … WebAug 21, 2024 · Background. In the last 50 years, dozens of clinical studies showed that dosing time-of-day can impact the efficacy and safety of many different types of medical treatments [1, 2].We know from multi-tissue studies in mice [] and humans [] that thousands of rhythmically expressed genes encode known drug targets.Circadian medicine aims to …

WebFeb 16, 2024 · Circadian clocks regulate numerous biological processes, at whole body, organ, and cellular levels. This includes both hormone secretion and target tissue sensitivity. Although growth hormone (GH) secretion is time-of-day-dependent (increased pulse amplitude during the sleep period), little is known regarding whether circadian clocks … Webfluctuations in both heart rate and blood pressure are abolished.23 However, these mice exhibit disruption of normal sleep/wake and fasting/feeding cycles, thus hindering dissociation of contributions from cell-auton-omous clocks versus behaviors.23,24 Cell-type–specific modulation of circadian clock components has proven to be very insightful.
WebFeb 16, 2024 · Numerous cardiovascular parameters are under circadian influence. Heart rate and blood pressure both fluctuate over a 24 h period (Degaute et al., 1991). Human studies designed to eliminate environmental and/or behavioral influences highlight circadian governance of key cardiovascular parameters (Scheer et al., 2010; Shea et al., 2011).
