Fig. 5From: Effect of bradykinin on TGF-β1-induced retinal pigment epithelial cell proliferation and extracellular matrix secretionEffect of 100 nM BK on Akt and Erk1/2 phosphorylation in RPE cells during different periods. a Western blotting results for Akt and Erk1/2 phosphorylation during different periods. b Akt phosphorylation levels increased most significantly after 1 min of BK stimulation. c/d Erk1/2 phosphorylation levels increased most significantly after 5 min of BK stimulation. *P < 0.05, ** P < 0.01, **** P < 0.0001 versus with 0 minBack to article page
