WebHowever, an alternative prenylation called geranyl-geranylation was found in N-Ras and K-Ras, but not in H-Ras, when farnesylation is blocked by FTIs [53,70]. This modification is a 20-carbon isoprenoid group transferred by GGTase-I. Geranyl-geranylated Ras is associated with the plasma membrane and active, rendering cancer cells driven by N ... WebSep 6, 2005 · Also, blocking farnesylation of authentic progerin in transiently transfected HeLa, HEK 293, and NIH 3T3 cells with farnesyltransferase inhibitors (FTIs) restored normal nuclear architecture. Last, treatment of both early- and late-passage human HGPS fibroblasts with FTIs resulted in significant reductions in nuclear blebbing. Our results ...
