Lidocaine inhibited cell proliferation and cell growth, and enhanced cell apoptosis.
Seven proteins were identified by 2-DE analysis and LC–MS/MS.
Using qRT-PCR, we confirmed that lidocaine up-regulated GNB2 with a 6.4-folds change.
Inhibition the expression of GNB2 by siRNAs attenuated the role of lidocaine.
Neuronal apoptosis was induced by lidocaine and this effect was mediated by GNB2.
