A, effect of YM-58483 on KCl-induced calcium response (n = 15 neurons). Left, representative 60 mm KCl-induced calcium responses; right, summary of the effect of YM-58483. B, representative TG-induced calcium responses recorded in neurons pretreated with mibefradil (Mib), nimodipine (Nim) or ω-conotoxin MVIIC (CTX). C, summary of the effects of mibefradil (n = 50 neurons), nimodipine (n = 45 neurons) and ω-conotoxin MVIIC (n = 32 neurons) on TG-induced SOCE. Values represent mean ± SEM; *P < 0.05, compared with control by Student's t test.
