Recent research involving mice has shown that molecular circadian clocks in the brain and muscle tissues work together to maintain muscle health, emphasizing the negative impacts of circadian disruptions on aging. The study suggests that both brain and muscle clocks must function harmoniously to prevent muscle aging, with eating patterns also playing a critical role in regulating these clocks.
A recent study in mice has revealed that molecular circadian clocks in the brain and muscle tissue work together to maintain muscle health and daily function. This research could offer crucial insights into how disruptions in circadian rhythms contribute to health problems related to aging and may suggest ways to preserve muscle function as people grow older.
A circadian molecular clock network is crucial for daily physiology and maintaining health. It’s thought that this network – which extends throughout all cells in the body – is hierarchically organized and coordinated by the brain’s suprachiasmatic nucleus , which receives daily light cues and synchronizes independent circadian clocks throughout the body.However, peripheral tissue clocks can also autonomously receive and respond to specific external cues.
The authors also show that time-restricted feeding during the active dark phase could partially replace the function of the central clock in the brain and enhance the overall autonomy of the muscle clock, underscoring the importance of eating patterns on molecular clock interactions.
