Background: The increased risk of gallstone has been reported in patients with ATP-binding cassette (ABC) transporter polymorphism. The half-transporters ABCG5 and ABCG8 mediate the efflux of cholesterol in hepatocytes and the intestine. We investigated whether ceramide plays a role in cholesterol efflux through the ABC transporters. Methods: Six-week-old C57BL/6J mice were assigned to 3 groups. The normal group (n = 5) was fed a normal chow diet, the cholesterol group (n = 10) was fed a lithogenic diet, and the myriocin group (n = 15) was fed the lithogenic diet and myriocin, a specific inhibitor of serine-palmitoyl transferase. After 6 weeks, the ABCG5 and ABCG8 transporters were analyzed. Results: The rate of cholesterol gallstone formation in cholesterol group was also higher than that in normal and myriocin groups (0, 70, and 40%, respectively). ABCG5 and ABCG8 mRNA levels were significantly increased in cholesterol group and less increased in myriocin group, relative to that in normal group (p < 0.05). Conclusions: The inhibition of ceramide biosynthesis by myriocin suppressed gallstone formation and ABCG5/8 mRNA expression. We expect that ceramide's role as a regulator of the ABCG5/8 transporter might be linked to cholesterol gallstone formation.

Quantitative trait locus (QTL) mapping was used to locate genes that determine the difference in cholesterol gallstone disease between the gallstone-susceptible strain C57L/J and the gallstone-resistant strain AKR/J. Gallstone weight was determined in 231 male (AKR × C57L) F1× AKR backcross mice fed a lithogenic diet containing 1% cholesterol, 0.5% cholic acid, and 15% butterfat for 8 wk. Mice having no stones and mice having the largest stones were genotyped at ∼20-cM intervals to find the loci determining cholesterol gallstone formation. The major locus, Lith1, mapped near D2Mit56 and was confirmed by constructing a congenic strain, AK.L- Lith1s. Another locus, Lith2, mapped near D19Mit58 and was also confirmed by constructing a congenic strain AK.L- Lith2s. Other suggestive, but not statistically significant, loci mapped to chromosomes 6, 7, 8, 10, and X. The identification of these Lith genes will elucidate the pathophysiology of cholesterol gallstone formation.

: Cholesterol gallstone disease is a major health problem in Westernized countries and depends on a complex interplay between genetic factors, lifestyle and diet, acting on specific pathogenic mechanisms. Overweigh, obesity, dyslipidemia, insulin resistance and altered cholesterol homeostasis have been linked to increased gallstone occurrence, and several studies point to a number of specific nutrients as risk- or protective factors with respect to gallstone formation in humans. There is a rising interest in the identification of common and modifiable dietetic factors that put the patients at risk of gallstones or that are able to prevent gallstone formation and growth. In particular, dietary models characterized by increased energy intake with highly refined sugars and sweet foods, high fructose intake, low fiber contents, high fat, consumption of fast food and low vitamin C intake increase the risk of gallstone formation. On the other hand, high intake of monounsaturated fats and fiber, olive oil and fish (ω-3 fatty acids) consumption, vegetable protein intake, fruit, coffee, moderate alcohol consumption and vitamin C supplementation exert a protective role. : The effect of some confounding factors (e.g., physical activity) cannot be ruled out, but general recommendations about the multiple beneficial effects of diet on cholesterol gallstones must be kept in mind, in particular in groups at high risk of gallstone formation.
