Effects of Cu-Zn superoxide dismutase (SOD) on si-SCN2A vector transfection induced resting membrane electric potential. (A and B) Downregulated transcript and protein expression levels in SCN2A following transfection with the si-SCN2A vector, respectively. (C) No significant signals were observed in the si-SCN2A vector groups by immunofluorescence compared with the other groups. (D) Cu-Zn SOD concentration among the control, empty vector and si-SCN2A vector groups. Different letters (a or b) show significant differences among the groups (P<0.05). (E) Resting membrane electric potential detected by single-cell patch clamp showed a repeated discharge caused by si-SCN2A while the overexpression of Cu-Zn SOD prevents the repeated discharge.
