How balance of cell oxidation affects the body's internal clock

Circadian oscillations in the redox state of peroxiredoxin are conserved in both prokaryotes and eukaryotes.

• Biological clocks in living organisms align with environmental cycles of light, temperature, and food availability.
• Redox oscillations are identified as a non-transcriptional mechanism contributing to timekeeping alongside classical models.
• Evidence suggests potential interactions between the circadian clock and the cell's redox status.
• The relationship between the classical transcription-translation feedback loop and redox oscillation remains unclear.
