چکیده انگلیسی
Piezo1 is a mechanosensitive cation channel that is activated by shear stress in endothelial cells (ECs). It has been shown to mediate shear-induced EC responses, including increased calcium influx, and vascular functions, such as vascular tone and blood pressure. Yoda1, a selective Piezo1 activator, has been shown to mimic shear-induced responses in ECs. Since shear-induced calcium influx causes Akt and ERK1/2 activation in ECs, we examined the effects of Yoda1 and the role of Piezo1 on their activation. Here, we show that Yoda1 robustly activates Akt and ERK1/2 in ECs. Additionally, the Piezo1 antagonists, gadolinium and ruthenium red, but not GsMTx4, effectively blocks Yoda1-induced Akt activation. Our results suggest that Yoda1-induced Akt and ERK1/2 activation is not dependent on Piezo1.
