Figure 5: A reduced aspirin cytoplasmatic concentration in MRP4 transfected Hek-293 cells. Percentage of aspirin cytoplasmatic concentration in MRP4 transfected cells (MRP4) after aspirin treatment (5 mM for 24 h) in comparison with those found in control cells (pCDNA 3.1). The results are expressed as mean ± SD of 3 experiments performed.
