    Abstract: 實驗利用初代肝細胞培養模式,分別添加Butaprost 0.01、0.1、1μM,再以Phenobarbital (PB)0.05mM誘發CYP 2B1表現,觀察Butaprost對CYP 2B1表現的影響。以Western Blot分析後發現Butaprost在1μM時對PB誘發CYP 2B1有最強的抑制效果,這個結果與之前PGE2處理細胞的結果是一致的。之後利用Northern Blot分析,也得到相同的結果。綜合以上的結果推測PGE2可能透過EP2 receptor來調控CYP 2B1的表現。另外實驗以PKA的抑制劑H-89 7.5μM處理初代肝細胞,然後以Western Blot分析發現PGE2對CYP 2B1的抑制效果會因PKA抑制劑的添加有逆轉現象。這個結果建議,PGE2影響CYP 2B1的表現可能是透過PKA的路徑。
