Figure 2From: Combining the receptor tyrosine kinase inhibitor AEE788 and the mammalian target of rapamycin (mTOR) inhibitor RAD001 strongly inhibits adhesion and growth of renal cell carcinoma cells Adhesion of RCC cells to HUVEC. A498, Caki-1 or KTC-26 cells were treated with 1 μM AEE788 or 1 nM RAD001, applied alone or in combination. After a 1 h pre-incubation, tumor cells were added at a density of 0.5 × 106 cells/well to HUVEC monolayers for 60 min. Non-adherent tumor cells were washed off in each sample, the remaining cells were fixed and counted in five different fields (5 × 0.25 mm2) using a phase contrast microscope. Mean values were calculated from five counts. Mean adhesion capacity is depicted as adherent cells/mm2. One representative of six experiments is shown. * indicates significant difference to controls (p < 0.05).Back to article page
