Nicotine 72-80 mitogen activated protein kinase 3 Rattus norvegicus 105-146 21742048-2 2011 In the present study, we demonstrated that nNOS expression enhances the nicotine-triggered activation of extracellular signal-regulated kinase 1/2 (ERK1/2) in nNOS-transfected PC12 (NPC12) cells. Nicotine 72-80 mitogen activated protein kinase 3 Rattus norvegicus 148-154 21742048-3 2011 Treatment with nicotine increased the phosphorylation level of ERK1/2 in the NPC12 cells as compared with that in control PC12 cells. Nicotine 15-23 mitogen activated protein kinase 3 Rattus norvegicus 63-69 21742048-5 2011 The nicotine-induced ERK1/2 phosphorylation in PC12 cells was observed by their pretreatment with a NO donor. Nicotine 4-12 mitogen activated protein kinase 3 Rattus norvegicus 21-27 21742048-6 2011 Moreover, the enhancement of nicotine-induced ERK1/2 phosphorylation in the NPC12 cells was regulated by intracellular glutathione levels, but not by the soluble guanylate cyclase-cGMP-protein kinase G signaling. Nicotine 29-37 mitogen activated protein kinase 3 Rattus norvegicus 46-52 21742048-8 2011 Taken together, these findings suggest that nicotine modulates NO-dependent redox condition; the resulting calcium influx, would increase ERK1/2 phosphorylation in nNOS expressing cells. Nicotine 44-52 mitogen activated protein kinase 3 Rattus norvegicus 138-144 21742048-9 2011 Blockade of NO pathway may be selective target to reduce ERK1/2 phosphorylation via attenuation of the nicotine responses in the CNS.
