Comparison of the inward rectifier K⁺ current (I_K1) and transient outward K⁺ currents (I_to) from both WT and M₃Tg mice with or without myocardial I/R. (A) Raw traces of I_K1 recorded from WT and M₃Tg mice. (B) The averaged current density-voltage (I-V) relationships of I_K1. (C) Raw traces of I_to recorded from WT and M₃Tg mice. (D) In the average I-V relationships of I_to, there were no differences among the four groups. I-V curves, mean from at least eight cells for each condition. (E) Raw traces of I_Ca,L recorded from WT and M₃Tg mice. (F) In the average I-V relationships of I_Ca,L, there were no significant differences between the four groups. I-V curves, mean from at least eight cells for each condition. The average data were presented as mean ± SEM.
