Mouse models of gallstone disease.

Area of Science:

• Hepatology and Gastroenterology
• Genetics and Genomics
• Animal Models in Disease Research

Background:

• Gallstone disease is a prevalent global health issue.
• Understanding the complex pathophysiology of gallstones is crucial for effective treatment.
• Mouse models offer a powerful platform for investigating gallstone formation.

Purpose of the Study:

• To summarize the establishment and utility of mouse models in gallstone research.
• To review the contribution of mouse models to genetic studies of gallstone disease.
• To highlight recent advances in understanding gallstone pathophysiology through mouse experiments.

Main Methods:

• Genomic strategies and phenotypic studies in mice.
• Creation of knockout or transgene mouse models for specific genes.
• Physical-chemical, genetic, and molecular biological analyses of gallstones in mice.

Main Results:

• Identification of multiple Lith genes, facilitating the discovery of human LITH genes.
• Elucidation of complex pathophysiological mechanisms involving interactions of five primary defects in cholesterol gallstone formation.
• Proposal of a new concept: hepatic hypersecretion of biliary cholesterol induced by Lith genes, insulin resistance, and environmental factors.

Conclusions:

• Mouse models are indispensable for understanding gallstone pathogenesis.
• Genetic and molecular insights from mouse studies enhance our comprehension of cholesterol gallstone disease in humans.
• Mouse models provide a foundation for discovering human LITH genes and understanding disease mechanisms.
