MTOR and cancer: Fig. 4B indicates the control OVCAR-3 cells (Fig. 4B1) and the OVCAR-3 cells treated with aPC (Fig. 4B2). The cancer cell migration was inhibited by PD 98059 an ERK inhibitor (Fig. 4B3), UO126 an MEK-1/2 kinase inhibitor (Fig. 4B4) and GGTI-298 an inhibitor of Rho GTPases (Fig. 4B5), whereas the migration was unaffected by FTI-277 an inhibitor of farnesyl transferase (Fig. 4B6) and rapamycin a raptor-mTor complex inhibitor (data not shown). The number of cells migrating outside the droplets, in five experiments, is presented in Fig. 4C.
