PG - 17-28 LID - 10.1016/j.canlet.2010.11.003 [doi] AB - The impact of the mTOR inhibitor RAD001 combined with the EGFr/VEGFr tyrosine kinase inhibitor AEE788 on prostate tumor cell growth, adhesion and migration was analyzed in vitro. The RAD001-AEE788 combination profoundly reduced tumor-endothelium and tumor-matrix contacts, suppressing cell growth and cell cycle progression. The underlying molecular mode of action depended on the cell phenotype, since cell cycle proteins, integrin subtype expression and integrin dependent signaling were altered in a different manner in PC-3 and DU-145 versus LNCaP prostate cancer cells. Simultaneous targeting of mTOR and VEGFr/EGFr related pathways may offer a novel therapeutic strategy for prostate cancer treatment. CI - Copyright (c) 2010 Elsevier Ireland Ltd. All rights reserved.
