Circadian regulation of hepatic detoxification: implications for drug-induced liver injury

Hepatic detoxification capacity exhibits pronounced circadian rhythmicity.

• The expression of drug-metabolizing enzymes and transporters in the liver is regulated by clock-controlled genes that follow a daily rhythm.
• Dysfunction in specific clock-controlled genes can disrupt the timing of liver metabolism and increase susceptibility to certain toxins.
• External factors like light and food can influence the liver's detoxification process by either synchronizing or disrupting its natural rhythms.
• Chronopharmacological principles may offer strategies for preventing drug-induced liver injury by optimizing the timing of drug administration.
