Circadian system in mitochondria
Šemíková, Johana ; Bendová, Zdeňka (advisor) ; Moravcová, Radka (referee)
The rhythms of circadian clocks throughout our bodies are not governed only by the light/dark cycle, but in many peripheral tissues circadian clocks are reset based on availability of nutrients and timing of food intake. The circadian system responds to changes in the levels of two metabolites (AMP and NAD+ ) that are central to biochemical reactions involved in energy production, storage, and utilization through the metabolic sensors AMPK and SIRT1. The aim of this review is to summarize mechanisms for energetic metabolism known to date that are connected with the regulation of circadian rhythms and explain their function in maintaining their stability. Last but not least, to show possible dysregulation of these mechanisms and their impact on the circadian system.
