To explore glutamine family amino acid metabolism of eight liver cell types in rat liver regeneration, eight kinds of rat regenerating liver cells were isolated by using the combination of Percoll density gradient centrifugation and immunomagnetic bead methods, then Rat Genome 230 2.0 Array was used to detect the expression profiles of the genes associated with metabolism of glutamine family amino acid in rat liver regeneration and finally how these genes involved in activities of eight regenerating liver cell types were analysed by the methods of bioinformatics and systems biology. The results showed that in the priming stage of liver regeneration, hepatic stellate cells and sinusoidal endothelial cells transformed proline and glutamine into glutamate; hepatocytes, hepatic stellate cells, sinusoidal endothelial cells and dendritic cells catabolized glutamate to 2-oxoglutarate or succinate; hepatic stellate cells and sinusoidal endothelial cells catalysed glutamate into glutamyl-tRNA for protein synthesis; urea cycle, which degraded from arginine, was enhanced in biliary epithelia cells, sinusoidal endothelial cells and dendritic cells; synthesis of polyamines from arginine was enhanced in biliary epithelia cells, sinusoidal endothelial cells, Kupffer cells and dendritic cells; the content of NO was increased in sinusoidal endothelial cells and dendritic cells; degradation of proline was enhanced in hepatocytes and biliary epithelia cells. In the progress stage, biliary epithelia cells converted glutamine into GMP and glucosamine 6-phosphate; oval cells converted glutamine into glucosamine 6-phosphate; hepatic stellate cells converted glutamine into NAD; the content of NO, which degraded from arginine, was increased in biliary epithelia cells, oval cells, pit cells and dendritic cells. In the termination stage, oval cells converted proline into glutamate; glutamate degradation, which degraded from arginine, was enhanced in hepatocytes and dendritic cells; the content of NO was increased in oval cells, sinusoidal endothelial cells, pit cells and dendritic cells. The synthesis of creatine phosphate was enhanced in hepatocytes, biliary epithelia cells, pit cells and dendritic cells in both progress and termination stages. In summary, glutamine family amino acid metabolism has some differences in liver regeneration in different liver cells.
