Dallegrave, E <a href=nolvadex.lol>tamoxifen ovarian cancer</a> Using cell lines derived from IGF IR independent mammary tumors from MTB IGFIR mice, it was demonstrated that PDGFRО± and to a lesser extent PDGFRОІ was important for cell migration and invasion as RNAi knockdown of PDGFRО± alone or PDGFRО± and PDGFRОІ in combination, significantly decreased tumor cell migration in Boyden chamber assays and suppressed cell migration in scratch wound assays
