Effects on voltage dependence of activation and inactivation. (A) Voltage-clamp protocol and representative current tracing for the onset of inactivation. (B) Effect of low-dose As2O3 on the time period of onset of inactivation following treatment for 24 h. (C) Voltage-clamp protocol and representative current tracing for recovery from inactivation. (D) Effect of low-dose As2O3 on the recovery from inactivation following treatment for 24 h. Data are presented as the mean ± standard error of the mean (n=6). *P<0.05 or **P<0.01 vs. control group. As2O3, arsenic trioxide; VC, voltage-clamp.
