Nicotine 203-211 protein kinase C alpha Homo sapiens 72-75 16450214-1 2006 PURPOSE: The aim of the study is to identify specific protein kinase C (PKC) isoforms involvement in K(+) transport mediated at altered blood-brain barrier (BBB) response to stroke conditions with prior nicotine exposure, which provides ways to intervene pharmacologically in PKC-mediated molecular pathways that could lead to effective treatment for smoking stroke patients. Nicotine 203-211 protein kinase C alpha Homo sapiens 276-279 16450214-2 2006 METHODS: Changes in PKC isoform levels were studied in the cytosolic and membrane fractions of bovine brain microvessel endothelial cells subjected to stroke conditions as well as nicotine/cotinine exposure. Nicotine 180-188 protein kinase C alpha Homo sapiens 20-23 16450214-4 2006 RESULTS: Membrane-bound PKCalpha, PKCbetaI, and PKCepsilon levels were increased after 6 h hypoxia/aglycemia, and this was attenuated by 24-h nicotine/cotinine exposure. Nicotine 142-150 protein kinase C alpha Homo sapiens 24-32 12421819-6 2003 Nicotine induces activation of PKC alpha and the MAPKs ERK1 and ERK2, which are physiological Bcl2 kinases. Nicotine 0-8 protein kinase C alpha Homo sapiens 31-40 16846598-0 2006 Nicotine-induced upregulation of human neuronal nicotinic alpha7-receptors is potentiated by modulation of cAMP and PKC in SH-EP1-halpha7 cells. Nicotine 0-8 protein kinase C alpha Homo sapiens 116-119 16846598-5 2006 Down-regulation of protein kinase C (PKC) with a phorbol ester abolishes the nicotine-induced upregulation of alpha7-nicotinic receptors. Nicotine 77-85 protein kinase C alpha Homo sapiens 37-40 16846598-6 2006 Furthermore, overexpression of PKCalpha in SH-EP1-halpha7 cells results in potentiation of nicotine-evoked upregulation indicating that PKC has a role in regulation of alpha7-nicotinic receptor number. Nicotine 91-99 protein kinase C alpha Homo sapiens 31-39 16846598-6 2006 Furthermore, overexpression of PKCalpha in SH-EP1-halpha7 cells results in potentiation of nicotine-evoked upregulation indicating that PKC has a role in regulation of alpha7-nicotinic receptor number. Nicotine 91-99 protein kinase C alpha Homo sapiens 31-34 16846598-8 2006 Taken together this study provides evidence that nicotine induces accumulation of cAMP and that the upregulation mechanisms of alpha7-nicotinic receptors are potentiated both by cAMP and PKC.
