HUVECs were pretreated with atorvastatin together with medium (black bars), mevalonate (white bars), squalene (grey bars) or GGPP (hatched bars) before IL-1β-stimulation. In the histogram the four bars of the same color represent cells pretreated with increasing doses of atorvastatin (from the left: 0, 1, 5 and 30 µM). Chemokine levels were measured by ELISA for GRO-α, IL-8, MCP-1 (A) and immunostaining for GRO-α (B). * p<0.05, ** p<0.01 and *** p<0.001 from IL-1β-treated control cells without atorvastatin.
