| Research Abstract |
The administration of Boiogito (BOT) was shown to ameliorate liver injury in the mice fed a cholate (CA)-supplemenetd diet. This effect was associated with a partial restoration of the reduction in liver triglyceride (TG) content. The levels of gene and protein of stearoyl-CoA desaturase-1 (SCD1) were lowered in the mice fed the CA-supplemented diet, which were elevated by BOT administration. These results suggest that the amelioration of CA-induced liver injury by BOT administration may be due to the restoration of reduced synthesis of liver TG through the facilitation of desaturation of saturated fatty acids, which is required in the efficient TG synthesis in liver. Alternatively, the reduction in liver TG levels might be a consequence of the amelioration of CA-induced liver injury by BOT administration. Thus, our lipidomic analysis revealed a novel mechanism involved in the modulation of lipid metabolism by a kampo medicine during bile acid-induced steatohepatitis in the mice.
