medicine | enzyme GGTase-I is abundantly expressed in human primary glioma tissues. Inhibition or downregulation of GGTase-I markedly decreases the proliferation of glioma cells and induces their apoptosis, while overexpression of GGTase-I promotes cell growth in vitro. Inactivation of GGTase-I eliminates geranylgeranylation of RhoA and Rac1, prevents them from targeting to the plasma membrane, and inhibits Rac1 activity. Overexpressing wild type or constitutively active Rac1 stimulates glioma cell growth, similar to the effect of GGTase-I overexpression. Overexpressing dominant-negative Rac1 or Rac1 with the prenylation site deleted or mutated abrogates GGTase-I-induced proliferation in glioma cells | Homo sapiens |
