PPAR Gamma Activators: Off-Target Against Glioma Cell Migration and Brain Invasion
Figure 2
The PPARγ inactive Δ 2-troglitazone (Δ2-TRO) inhibits glioma cell
migration. The glioma cell
migration assay (Boyden chamber; QCM-FN Migration Assay, Chemicon, Temecula, Calif, USA) was performed as described recently [9]. Briefly, F98 rat
glioma cells, pretreated with the test compound or solvent for 24 hours, were
transferred into each Boyden chamber. After 24 hours of incubation, cells which
migrated through the fibronectin-coated
chamber membranes (8 micron pore diameter) were quantified according to
the manufacturer’s protocol. Experiments were repeated 3 times (). (** = ; *** = ; -test). Right panel: representative
microphotographs of F98 glioma cells which migrated though the
fibronectin-coated chamber membranes after treatment with Δ2-TRO (20 M) or solvent only.
