[Objective] The aim of the research was to study the expression profile changes of genes involved in lipid metabolism pathway during liver regeneration in mice. [Method] The CCl4 induced mouse model of liver regeneration was established and the total RNA was isolated from liver tissue of mouse. Then the changes of genes involved in lipid metabolism pathway during different stages of liver regeneration were detected through micro-array chip gene technique and their specific functions were also analyzed. [Result] During the process of liver regeneration, the expression level of 98 genes involved in lipid metabolism pathway changed, which were divided into eight groups according to change trend. In the mass, the expression of genes was inhibited in the early stage and up-regulated in the late phase. And the gene expression associated with fatty acid synthesis pathway was mainly up-regulated while the catabolic pathway did not change significantly. Most of genes involved in bile acid synthesis pathway were suppressed before 4.5 d and up-regulated after 4.5 d or 7 d. [Conclusion] During the process of liver regeneration, the genes associated with lipid metabolism are expressed in different trends, and this data should provide a specific range of genes for further studying the regulation effect of lipid metabolism related pathway on liver regeneration.
