“…In addition to early findings that isoprenoids may inhibit posttranslational protein prenylation (Crowell et al, 1991;Ren et al, 1997), reported effects include induction of G 0 /G 1 cell cycle arrest (Yu et al, 1995;Miquel et al, 1998;Clark et al, 2002;Elegbede et al, 2003), increased apoptosis (Haug et al, 1994;Mills et al, 1995;Reddy et al, 1997;Stayrook et al, 1997;Ariazi et al, 1999;Rioja et al, 2000;Burke et al, 2002;Clark et al, 2002;Elegbede et al, 2003;Xu et al, 2004), transient G 2 /M phase arrest (Shi and Gould, 2002;Rajesh and Howard, 2003), inhibition of cholesterol biosynthesis (Ren and Gould, 1994;Peffley and Gayen, 2003), inhibition of angiogenesis (Loutrari et al, 2004), and increased sensitization to radiation and anticancer drugs (Samaila et al, 2004).…”
