Nicotine 32-40 prodynorphin Mus musculus 61-70 27656031-11 2016 Considered together, our findings suggest that activation of the DYN/KOR system and Galphai signaling within the BLA is both necessary and sufficient to produce reinstatement of nicotine preference. Nicotine 178-186 prodynorphin Mus musculus 65-68 27656031-15 2016 Here, we report region-specific engagement of the DYN/KOR system and subsequent activation of inhibitory (Gi-linked) intracellular signaling pathways within the basolateral amygdala during stress-induced reinstatement of nicotine preference. Nicotine 221-229 prodynorphin Mus musculus 50-53 18807250-0 2009 Acute nicotine changes dynorphin and prodynorphin mRNA in the striatum. Nicotine 6-14 prodynorphin Mus musculus 23-32 18937881-0 2009 Prodynorphin gene disruption increases the sensitivity to nicotine self-administration in mice. Nicotine 58-66 prodynorphin Mus musculus 0-12 18937881-2 2009 The aim of the study was to determine the contribution of the endogenous peptides derived from prodynorphin in acute and chronic nicotine responses, mainly those related to its addictive properties. Nicotine 129-137 prodynorphin Mus musculus 95-107 18937881-8 2009 However, a shift to the left in the percentage of acquisition of intravenous nicotine-self administration was observed in prodynorphin KO mice. Nicotine 77-85 prodynorphin Mus musculus 122-134 18937881-11 2009 These findings reveal a specific role of endogenous peptides derived from prodynorphin in nicotine self-administration, probably through the modulation of its aversive effects. Nicotine 90-98 prodynorphin Mus musculus 74-86 18807250-0 2009 Acute nicotine changes dynorphin and prodynorphin mRNA in the striatum. Nicotine 6-14 prodynorphin Mus musculus 37-49 18807250-3 2009 OBJECTIVE: We determined whether administration of a single dose of nicotine alters the biosynthesis of Dyn in the striatum of mice. Nicotine 68-76 prodynorphin Mus musculus 104-107 18807250-4 2009 RESULTS: Nicotine free base, 1 mg/kg, sc, induced a biphasic, protracted increase of striatal Dyn, an initial rise by 1 h, which declined to control levels by 2 h, and a subsequent increase, between 6 and 12 h, lasting over 24 h. At 1 h, the nicotine effect was dose dependent, with doses>or=0.5 mg/kg inducing a response. Nicotine 9-17 prodynorphin Mus musculus 94-97 18807250-7 2009 The glutamate NMDA receptor antagonist MK-801 reversed the nicotine-induced increase of Dyn, while the AMPA antagonist NBQX had a marginal effect. Nicotine 59-67 prodynorphin Mus musculus 88-91 18807250-8 2009 CONCLUSIONS: We interpret our findings to indicate that acute nicotine enhances the synthesis and release of striatal Dyn. Nicotine 62-70 prodynorphin Mus musculus 118-121 18807250-9 2009 We propose that nicotine influences Dyn primarily through dopamine release and that glutamate plays a modulatory role. Nicotine 16-24 prodynorphin Mus musculus 36-39 15542756-0 2004 Alpha 7-type nicotinic acetylcholine receptor and prodynorphin mRNA expression after administration of (-)-nicotine and U-50,488H in beta-amyloid peptide (25-35)-treated mice. Nicotine 103-115 prodynorphin Mus musculus 50-62 18361441-0 2008 Dynorphin and prodynorphin mRNA changes in the striatum during nicotine withdrawal. Nicotine 63-71 prodynorphin Mus musculus 14-26 18361441-3 2008 In this regard, the opioid dynorphin (Dyn) is of interest as it produces aversive states and has been speculated to play a role in the nicotine behavioral syndrome. Nicotine 135-143 prodynorphin Mus musculus 38-41 18361441-4 2008 These studies explore whether Dyn metabolism is altered during withdrawal following chronic administration of nicotine. Nicotine 110-118 prodynorphin Mus musculus 30-33 15542756-3 2004 In the present study, we tested whether (-)-nicotine and U-50,488H prevent delayed-memory impairment induced by beta-amyloid peptide (25-35), and changes of expression of alpha7-type nicotinic acetylcholine receptor mRNA and prodynorphin mRNA. Nicotine 40-52 prodynorphin Mus musculus 225-237
