However, recent advances have unveiled a broader role for circadian clocks across various tissues, including skeletal muscle. Within this context, the investigation of circadian clocks within the skeletal muscle milieu has emerged as a frontier of scientific inquiry. These intrinsic timekeeping mechanisms exhibit multifaceted regulatory capacities beyond mere temporal synchronization. This episode delves into the implications of “circadian clocks” operating within skeletal muscle tissue, with the esteemed Prof. Karyn Esser as this week’s guest. Her pioneering work has been instrumental in understanding the interplay between circadian rhythmicity and muscular physiology.
