Glucose Release Induced by 1,2-Dioctanoyl-sn-Glycerol in Perfused Rat Liver

관류 흰쥐 간에서 1,2-Dioctanoyl-sn-Glycerol에 의한 글루코오스의 유리작용

The effect of diacylglycerol on glucose release was studied by using 1,2-dioctanoyl-sn-glycerol ($diC_8$), a cell permeable diacylglycerol, in perfused rat liver. The glucose release was increased by $diC_8(50\;{\mu}M$), and the effect was depended on calcium ions. The increment of glucose release by $diC_8(50\;{\mu}M$) was inhibited by indomethacin ($50\;{\mu}M$); the amount of glucose release was almost the same with that of control group. Arachidonic acid($200\;{\mu}M$) also increased glucose release and the release was inhibited by indomethacin. There was no synergistic effect on glucose release by the combination of $diC_8(50\;{\mu}M$) and phenylephrine($10\;{\mu}M$).
