Abstract

Circadian rhythms, which are ~24 h cycles, play a significant role in health and disease.

  • Disruption of circadian rhythms may contribute to the progression of cancers and aging-related declines in function.
  • Small molecules identified can modulate core circadian clock proteins and pathways, presenting potential therapeutic strategies.
  • Clock-modulating compounds have been shown to impact tumor metabolism, cell growth, and effectiveness of cancer treatments.
  • Strengthening circadian function in aging models may improve metabolic health and potentially increase longevity.
  • Challenges include managing off-target effects and understanding the complex regulation of circadian clocks.
