DEX inhibits PTX-induced apoptosis in ovarian cancer SKOV-3 cells. SKOV-3 cells were either left untreated (Con) or treated with PTX (50 nM) in the absence or presence of DEX (0.1 μM), which was added 24 h prior to PTX treatment. Twenty-four hours after the addition of PTX, apoptosis rate was measured by PI-staining and then analyzed by FCM. *: p < 0.01 vs. control; *#: p < 0.01 vs. PTX treated cells. Con: control; PTX: paclitaxel; DEX: dexamethasone.
