Up-regulation of Cav3.1 expression in SH-SY5Y cells induced by lidocaine hydrochloride.
Artificial Cells, Nanomedicine, and Biotechnology 2018 January 13
BACKGROUND: Neurotoxicity induced by the local anaesthetics has aroused concern. A previous study has shown that an overload of intracellular calcium was involved in the neurotoxic effect. Cav3.1 is one of the low-voltage-activated (LVA) calcium channels which play a key point to regulate the intracellular calcium ion level. This study aimed to investigate the changes of the Cav3.1 expression in the SH-SY5Y cells treated with lidocaine hydrochloride.
METHODS: The SH-SY5Y cells were treated with different concentrations of lidocaine hydrochloride(1 mM, 5 mM and 10 mM, namely L1 group, L5 group and L10 group) and different exposure times (1 h,12 h and 24 h), respectively. Cell viability, Cav3.1 protein and mRNA expression were detected.
RESULTS: The results showed that cell viability decreased and Cav3.1 mRNA and protein expression increased with the concentration (from 1 mM to 10 mM) of the lidocaine hydrochloride and exposure time (from 1 h to 24 h) to the SH-SY5Y cell line increased.
CONCLUSION: Those data showed that lidocaine hydrochloride induced SH-SY5Y cell toxicity and up-regulated Cav3.1mRNA and protein expression.
