Effect of oleuropein on viability of proliferating and differentiated 3T3-L1 cells. Cells were cultured in appropriate medium at 37 °C in a humidified 5 % CO₂, in the absence or presence of oleuropein (Oleu—0, 1, 10, 100, 200 and 400 μM) and in the presence or absence of catalase (CAT; 100 units/ml)
