A review of the role of caveolin-1 in APAP-induced liver injury.

BACKGROUND:Acetaminophen is commonly used as an antipyretic and analgesic agent. Excessive APAP can induce liver toxicity, known as APAP induced liver injury (ALI). The metabolism and pathogenesis of APAP have been extensively studied in recent years, and many cellular processes such as autophagy, mitochondrial oxidative stress, mitochondrial dysfunction and liver regeneration have been identified to be involved in the pathogenesis of ALI. Caveolin-1 (CAV-1) as a scaffold protein has also been shown to be involved in the development of various diseases, especially liver disease and tumorigenesis. The role of CAV-1 in the development of liver disease and the association between them remains a challenging and uncharted territory. SUMMARY:In this review, we briefly explore the potential therapeutic effects of CAV-1 on APAP induced ALI through autophagy, oxidative stress, and lipid metabolism. Further research to better understand the mechanisms by which CAV-1 regulates liver injury will not only enhance our understanding of this important cellular process, but also help develop new therapies for human disease by targeting CAV-1 targets. KEY MESSAGES:This review briefly summarizes the potential protective mechanisms of CAV-1 against liver injury caused by APAP.
