GCG-induced inhibitory effect on tetrodotoxin-resistant Na+ currents in rat dorsal root ganglia (DRG) neurons. (A) Example time courses of tetrodotoxin-resistant Na+ current in the absence (unfilled circles) and presence of 1 μM GCG (filled circles); (B) Representative tetrodotoxin-resistant Na+ currents in rat DRG neurons; (C) The blockade of tetrodotoxin-resistant Na+ currents after treatment with 1 μM GCG for 5 min (n = 6); (D) Concentration-response curve of tetrodotoxin-resistant Na+ currents inhibition by GCG (n = 4).
