MEK-1 dependency of VEGF-induced proliferation.
MM.1S cells were starved for 3 hours in RPMI 1640 with 5% FBS. Cells were incubated with 100 or 1000 ng/mL VEGF165 with or without PD98059 (25μM) or BIM (2μM). For the last 9 hours of 72-hour cultures, 0.5μCi [3H] thymidine was added, and radioactivity incorporated into DNA was determined by scintillation counting (Wallac Trilux Betaplate scintillation counter) of automatically harvested cells (Tomec Harvester 96 Mach III).
