Effect of different concentrations of BK on Akt and Erk1/2 phosphorylation in RPE cells. a Akt phosphorylation levels increased most significantly after 1 min of BK stimulation. b Erk1/2 phosphorylation levels increased most significantly after 5 min of BK stimulation. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001 versus with 0 nM BK
