The chronic effect of PMA on IKs current in HEK 293B cell. (a) The representative IKs current under the PMA (100 nM) treatment. (b) The current–voltage relationship for the tail currents under the PMA (100 nM) treatment. (c) The summary data for the tail currents under the PMA (100 nM) treatment at +40 mV prepulse. (d) The normalized I–V relationship for IKs current. The solid lines represent fits to a Boltzmann function. (e) The representative immunoblot and summary data for the KCNQ1 channel membrane protein under the PMA (100 nM) treatment (**P < 0.01, compared with the control group)
