Most of these deep viscous oils in loujia - kenxi region show no sign of biodegradation effects based on n - alkane and acyclic isoprenoid distributions 罗家-垦西稠油大部分样品饱和烃中正构烷烃分布十分完整，不具有生物降解特征。

Gfp - oscam61 was transported into the nucleoplasm upon a block in isoprenoid biosynthesis by mevinolin treatment of tobacco cells . these results indicate that the prenylated oscam61 molecules are mainly membrane - associated while its unprenylated counterparts are transported into the nucleoplasm . thus , oscam61 may play functions in coordinating ca2 + signaling with isoprenoid metabolism 用抑制异戊烯合成途径的mevinolin处理转化了gfp - oscam61的烟草细胞，原来定位于膜上的gfp - oscam61则进入细胞核，说明异戊烯化的oscam61结合在膜上而它的非异戊烯化形式存在于细胞核质中，因此， oscam61同时受钙信号和异戊烯代谢的调控，并可能在钙信号传递和异戊烯代谢的协调过程中发挥功能。
