Comparison of the inverse agonist activities of olmesartan and losartan against stretch-induced ERK activation. HEK293-AT1 cells were stimulated by mechanical stretch, and the activation of extracellular signal-regulated protein kinase (ERKs) was determined. The inhibitory effect of 10−7 M olmesartan on stretch-induced ERK activation was much stronger than that of 10−7 M losartan. *P<0.01 vs. that of losartan. AT1, angiotensin II type 1.
