High sucrose diet-induced abnormal lipid metabolism in mice is related to the dysbiosis of gut microbiota

Excess sucrose intake induces metabolic syndrome. In human, abnormal lipids metabolism like obesity, hyperlipidemia and fatty liver are induced. However, excess sucrose causes different phenotypes in different species. Based on our previous study, excess sucrose induced fatty liver and hyperlipidemi...

Description
Summary:Excess sucrose intake induces metabolic syndrome. In human, abnormal lipids metabolism like obesity, hyperlipidemia and fatty liver are induced. However, excess sucrose causes different phenotypes in different species. Based on our previous study, excess sucrose induced fatty liver and hyperlipidemia in rats. The phenotypes and mechanism of abnormal lipid metabolism in mice is unclear. We investigated the different phenotypes in 5 strains of mice and the relationship between gut microbiome and abnormal lipid metabolism in C57BL/6N mice. We examined the effect of a high sucrose diet in 5 different strains of mice. Besides, to find out the relationship between gut microbiome and metabolic disorder induced by excess sucrose, C57BL/6N mice were fed with a high sucrose diet with or without antibiotics cocktail. A high sucrose diet induced obesity and fatty liver in inbred mice, whereas did not induce hyperlipidemia in all strains of mice. Moreover, a high sucrose diet changed the composition of gut microbiota in C57BL/6N mice. Antibiotics treatment alleviated the abnormal lipid metabolism induced by high sucrose diet by changing the composition of gut short chain fatty acids. These results indicates that the phenotypes of metabolic syndrome are influenced by genetic factors. Furthermore, the dysbiosis of gut microbiome caused by excess sucrose may contribute to the development of abnormal lipid metabolism via its metabolites.
