1Center for Molecular Metabolism, Nanjing University of Science and Technology, Nanjing, China.
Circadian rhythms regulate nutrient metabolism and are linked to obesity. Bile acids, influenced by feeding cycles and circadian disruption, play a key role in metabolic health.
Area of Science:
- Chronobiology
- Metabolic Science
- Gastroenterology
Background:
- Circadian rhythms synchronize cellular processes with daily cycles, impacting nutrient metabolism.
- Bile acids are crucial for nutrient absorption and energy regulation, closely tied to metabolic disorders.
- Disruptions in circadian rhythms are increasingly linked to obesity and metabolic dysfunction.
Purpose of the Study:
- To review the interplay between circadian rhythms and bile acid metabolism.
- To explore the implications for metabolic diseases like obesity.
- To discuss future research directions and therapeutic potential.
Main Methods:
- Literature review and synthesis of current research on circadian rhythms, bile acids, and metabolism.
- Analysis of how feeding-fasting cycles and disruptions affect bile acid homeostasis.
- Examination of the role of gut microbiome in this interaction.
Main Results:
- Circadian rhythms regulate bile acid pool size, composition, and signaling.
- Disruptions (e.g., shift work, diet) alter bile acid metabolism, increasing obesity risk.
- Factors like diet, alcohol, and genetic mutations can desynchronize circadian rhythms and affect bile acids.
Conclusions:
- Circadian rhythms and bile acid metabolism are intricately linked, influencing energy balance and metabolic health.
- Understanding this connection is vital for addressing obesity and metabolic disorders.
- Maintaining bile acid homeostasis through circadian-aligned strategies may offer therapeutic benefits.

Circadian Rhythms and Gene Regulation
Factors Affecting Drug Biotransformation: Biological
Species differences: Variations in enzyme systems across species can cause disparities in drug metabolism. For instance, humans may metabolize certain drugs faster than rodents, altering therapeutic effects.
Strain differences: Genetic variations within a species can result in differing enzyme activity, impacting drug response and toxicity. For example, some mouse strains may...
Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...
Hepatic Drug Excretion: Enterohepatic Cycling
Post-release drugs and metabolites can be reabsorbed into the body from the intestine. For conjugated metabolites like glucuronides, reabsorption requires enzymatic hydrolysis by intestinal microflora. This...

Liver Physiology
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
