| Research Abstract |
We establish paclitaxel-resistant PCa cells (PtxR PC3) and assess the anti-cancer activity of antisense oligonucleotide (ASO) targeting human IGF-IR in vitro and in vivo. We observed dose- and sequence-specific suppression of IGF-IR expression in IGF-1R ASO -treated PtxR PC3 cells in vitro which correlated with decreased proliferation and increased apoptosis. Combination of IGF-1R ASO with paclitaxel showed the drug interactions resulted in synergy in vitro. IGF-1R ASO suppressed PtxR PC3 tumor growth as a combination therapy with paclitaxel in vivo. In conclusion, IGF-IR ASO suppresses growth of PtxR PC3 tumors, synergistically enhancing paclitaxel sensitivity.
