Figure 6. Knockdown of KCNIP1 downregulates transient outward currents in atrial myocytes.

Figure 6

(a) Transient outward current (Ito) was obtained by a family of depolarization steps from −80 mV, and was measured as the 4-aminopyridine (4-AP)-sensitive peak current (10 mM). (left upper) Voltage protocol. Right panel shows the representative recordings of 4-AP sensitive currents of the control (CTL) and KCNIP1 knockdown (KCNIP1 KD) atrial myocytes, respectively. (left lower) Efficiency of knockdown represented by decreased KCHIP1 protein level. (b) Representative current density–voltage relationships of 4-AP sensitive currents in CTL and KCNIP1 KD atrial myocytes. N=3 experiments for each group. Error bars, s.d. Full-length blots are presented in Supplementary Fig. 7.
