Abstract
To investigate the biological effect of cerivastatin on glioblastoma cells, we exposed them to various concentrations of cerivastatin. Cerivastatin exhibited dual effects on glioblastoma cells in a dose-dependent manner. Immunofluorescence microscopy showed disruption of actin stress fibers and focal adhesion plaques even at nanomolar concentrations. Matrigel assay demonstrated marked inhibition of glioblastoma cell invasion. Immunoblot analysis using a phosphospecific antibody against focal adhesion kinase (FAK) showed that inhibition of migration was associated with the down-regulation of tyrosine phosphorylation of FAK. Our data suggest that cerivastatin may be beneficial for combination therapy with conventional anti-cancer drugs by inhibiting the invasion of glioblastoma.
