Abstract

Circadian rhythms may significantly influence gut microbiota and cancer progression.

  • disruptions can lead to imbalances in gut microbiota, known as .
  • Changes in gut microbiota may alter the (TME) and promote cancer growth.
  • Disrupted circadian rhythms could modify the diversity and functions of gut microbiota, affecting metabolites like short-chain fatty acids.
  • These metabolic changes may influence immune cell behavior and tumor cell metabolism in the TME.
  • Therapeutic strategies targeting the circadian-microbiome connection include chronotherapy and probiotic use.
  • More research is needed to clarify how circadian rhythms and gut microbiota interact, and to create personalized treatments for cancer.
