Scratch wound migration assays were conducted using stably transfected MCF-7 cells. Confluent monolayers of transfected MCF-7 cells in 24-well plates were serum starved for 24 h to induce quiescence, and were then treated for 1 h with either serum free media, vehicle control, 70 nM UO126 (1,4-diamino-2,3-dicyano-1,4-bis(2-aminophenylthio)butadiene; Abcam, Melbourne, VIC, Australia), or 1.5 nM PF-562271 (N-Methyl-N-[3-[[[2-[2-oxo-1,3-dihydroindol-5-yl)amimo]-5-(trifluoromethyl)pyrimidin-4-yl]amino)pyridine-2-yl)methanesulfonamide; Abcam). Following this, a scratch wound migration assay was performed as previously described (30 (link)).
