Abstract：
BACKGROUND:Farnesyltransferase inhibitor R115777 (Tipifamib, Zarnestra) is active in breast cancer, but its efficacy in drug combinations has not been extensively investigated. MATERIALS AND METHODS:The activity of R115777 and paclitaxel, alone and in combination, was studied in the human breast cancer cell lines, BT-474 (overexpressed HER2/neu) and MDA-MB-231 (low HER2/neu), with cell viability and biomarkers for farnesylation (HDJ-2, Rho B), tumor growth (Raf/MEK/ERK), survival (PI3K/Akt) and angiogenesis (VEGF, FGF-2, MMP-1, MMP-2, MMP-9) as the endpoints. RESULTS:The drug combination resulted in additive cytotoxicity. R115777 +/- paclitaxel inhibited HDJ-2 farnesylation, up-regulated RhoB, transiently lowered (P)ERK/ERK and (P)Akt/Akt, reduced Raf-1 and MEK and inhibited secretion of VEGF and MMP-1. CONCLUSION:The effect of R115777 on prenylation biomarkers is consistent with its mechanism of action. The drug interfered with tumor growth, survival and angiogenesis pathways in breast cancer models with low or overexpressed HER2/neu receptor. The combination of R115777 with paclitaxel might offer clinical advantage over monotherapies.
