Neurotoxicity Induced by Bupivacaine via T-Type Calcium Channels in SH-SY5Y Cells
Figure 4
Bupivacaine treatment leads to an increase in cytosolic Ca2+ ([Ca2+]i).
SH-SY5Y cells were either pretreated with the indicated concentrations of NNC 55-0396 dihydrochloride or left untreated prior to 1 mM bupivaine treatment for 24 h. [Ca2+]i levels were measured by Quest Fluo-8 AM ester (mean±SD, n = 6)). A: Representative image of Quest Fluo-8 AM ester flow cytometry analysis. B: [Ca2+]i levels in the different treatment groups. aP<0.05 vs. S group; bP<0.05 vs. S+NNC 100 group; cP<0.05 vs. S+B group; dP<0.05 vs. S+B+NNC 10 group.
