abstract：:Local anesthetic may cause neurotoxicity in developing neurons. In this study, we examined the molecular mechanisms of microRNA-210 (miR-210) in regulating bupivacaine-induced dorsal root ganglia (DRG) neurotoxicity in vitro. Young mouse (P30) DRG explants were cultured in vitro and treated with 5 mM bupivacaine to in...
