    Description: The nucleus accumbens is a key mediator of cocaine reward, but the distinct roles of the two subpopulations of nucleus accumbens projection neurons, those expressing dopamine D1 versus D2 receptors, are poorly understood. We show that deletion of TrkB, the brain-derived neurotrophic factor (BDNF) receptor, selectively from D1+ or D2+ neurons oppositely affects cocaine reward. Because loss of TrkB in D2+ neurons increases their neuronal excitability, we next used optogenetic tools to control selectively the firing rate of D1+ and D2+ nucleus accumbens neurons and studied consequent effects on cocaine reward. Activation of D2+ neurons, mimicking the loss of TrkB, suppresses cocaine reward, with opposite effects induced by activation of D1+ neurons. These results provide insight into the molecular control of D1+ and D2+ neuronal activity as well as the circuit-level contribution of these cell types to cocaine reward.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3011229/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3011229/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lobo, Mary Kay -- Covington, Herbert E 3rd -- Chaudhury, Dipesh -- Friedman, Allyson K -- Sun, HaoSheng -- Damez-Werno, Diane -- Dietz, David M -- Zaman, Samir -- Koo, Ja Wook -- Kennedy, Pamela J -- Mouzon, Ezekiell -- Mogri, Murtaza -- Neve, Rachael L -- Deisseroth, Karl -- Han, Ming-Hu -- Nestler, Eric J -- P01 DA008227/DA/NIDA NIH HHS/ -- P01 DA008227-20/DA/NIDA NIH HHS/ -- R01 DA007359/DA/NIDA NIH HHS/ -- R01 DA007359-22/DA/NIDA NIH HHS/ -- R01 DA014133/DA/NIDA NIH HHS/ -- R01 DA014133-10/DA/NIDA NIH HHS/ -- R01 DA014133-11/DA/NIDA NIH HHS/ -- R01 DA014133-12/DA/NIDA NIH HHS/ -- R01 MH051399/MH/NIMH NIH HHS/ -- R01 MH051399-19/MH/NIMH NIH HHS/ -- R01 MH051399-20/MH/NIMH NIH HHS/ -- T32 DA007135-26A2/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 15;330(6002):385-90. doi: 10.1126/science.1188472.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fishberg Department of Neuroscience, Mount Sinai School of Medicine, New York, NY 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20947769" target="_blank"〉PubMed〈/a〉

    Description: Cocaine-induced alterations in gene expression cause changes in neuronal morphology and behavior that may underlie cocaine addiction. In mice, we identified an essential role for histone 3 lysine 9 (H3K9) dimethylation and the lysine dimethyltransferase G9a in cocaine-induced structural and behavioral plasticity. Repeated cocaine administration reduced global levels of H3K9 dimethylation in the nucleus accumbens. This reduction in histone methylation was mediated through the repression of G9a in this brain region, which was regulated by the cocaine-induced transcription factor DeltaFosB. Using conditional mutagenesis and viral-mediated gene transfer, we found that G9a down-regulation increased the dendritic spine plasticity of nucleus accumbens neurons and enhanced the preference for cocaine, thereby establishing a crucial role for histone methylation in the long-term actions of cocaine.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2820240/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2820240/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maze, Ian -- Covington, Herbert E 3rd -- Dietz, David M -- LaPlant, Quincey -- Renthal, William -- Russo, Scott J -- Mechanic, Max -- Mouzon, Ezekiell -- Neve, Rachael L -- Haggarty, Stephen J -- Ren, Yanhua -- Sampath, Srihari C -- Hurd, Yasmin L -- Greengard, Paul -- Tarakhovsky, Alexander -- Schaefer, Anne -- Nestler, Eric J -- P01 DA008227/DA/NIDA NIH HHS/ -- P01 DA008227-120001/DA/NIDA NIH HHS/ -- P01 DA008227-129001/DA/NIDA NIH HHS/ -- P01 DA008227-13/DA/NIDA NIH HHS/ -- P01 DA008227-14/DA/NIDA NIH HHS/ -- P01 DA008227-15/DA/NIDA NIH HHS/ -- P01 DA008227-16/DA/NIDA NIH HHS/ -- P01 DA008227-170003/DA/NIDA NIH HHS/ -- P01 DA008227-180003/DA/NIDA NIH HHS/ -- P01 DA010044/DA/NIDA NIH HHS/ -- P01 DA010044-14/DA/NIDA NIH HHS/ -- P01 DA010044-140005/DA/NIDA NIH HHS/ -- P01 DA010044-149002/DA/NIDA NIH HHS/ -- P01 DA010044-14S1/DA/NIDA NIH HHS/ -- P01 DA010044-14S10005/DA/NIDA NIH HHS/ -- P01 DA010044-14S19002/DA/NIDA NIH HHS/ -- P01 DA010044-15/DA/NIDA NIH HHS/ -- P01 DA010044-150005/DA/NIDA NIH HHS/ -- P01 DA010044-159002/DA/NIDA NIH HHS/ -- P01 DA08227/DA/NIDA NIH HHS/ -- P0110044/PHS HHS/ -- R01 DA007359/DA/NIDA NIH HHS/ -- R01 DA007359-02/DA/NIDA NIH HHS/ -- R01 DA007359-17/DA/NIDA NIH HHS/ -- R01 DA007359-18/DA/NIDA NIH HHS/ -- R01 DA007359-19/DA/NIDA NIH HHS/ -- R01 DA007359-20/DA/NIDA NIH HHS/ -- R01 DA007359-21/DA/NIDA NIH HHS/ -- R01 DA007359-22/DA/NIDA NIH HHS/ -- R01 DA014133/DA/NIDA NIH HHS/ -- R01 DA07359/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 8;327(5962):213-6. doi: 10.1126/science.1179438.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fishberg Department of Neuroscience, Mount Sinai School of Medicine, New York, NY, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20056891" target="_blank"〉PubMed〈/a〉

    Description: Brain-derived neurotrophic factor (BDNF) is a key positive regulator of neural plasticity, promoting, for example, the actions of stimulant drugs of abuse such as cocaine. We discovered a surprising opposite role for BDNF in countering responses to chronic morphine exposure. The suppression of BDNF in the ventral tegmental area (VTA) enhanced the ability of morphine to increase dopamine (DA) neuron excitability and promote reward. In contrast, optical stimulation of VTA DA terminals in nucleus accumbens (NAc) completely reversed the suppressive effect of BDNF on morphine reward. Furthermore, we identified numerous genes in the NAc, a major target region of VTA DA neurons, whose regulation by BDNF in the context of chronic morphine exposure mediated this counteractive function. These findings provide insight into the molecular basis of morphine-induced neuroadaptations in the brain's reward circuitry.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3547365/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3547365/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koo, Ja Wook -- Mazei-Robison, Michelle S -- Chaudhury, Dipesh -- Juarez, Barbara -- LaPlant, Quincey -- Ferguson, Deveroux -- Feng, Jian -- Sun, Haosheng -- Scobie, Kimberly N -- Damez-Werno, Diane -- Crumiller, Marshall -- Ohnishi, Yoshinori N -- Ohnishi, Yoko H -- Mouzon, Ezekiell -- Dietz, David M -- Lobo, Mary Kay -- Neve, Rachael L -- Russo, Scott J -- Han, Ming-Hu -- Nestler, Eric J -- K99 MH094405/MH/NIMH NIH HHS/ -- P01 DA008227/DA/NIDA NIH HHS/ -- R01 DA014133/DA/NIDA NIH HHS/ -- R01 MH092306/MH/NIMH NIH HHS/ -- T32 MH087004/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2012 Oct 5;338(6103):124-8. doi: 10.1126/science.1222265.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fishberg Department of Neuroscience and Friedman Brain Institute, Mount Sinai School of Medicine, New York, NY 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23042896" target="_blank"〉PubMed〈/a〉

    Description: Typical therapies try to reverse pathogenic mechanisms. Here, we describe treatment effects achieved by enhancing depression-causing mechanisms in ventral tegmental area (VTA) dopamine (DA) neurons. In a social defeat stress model of depression, depressed (susceptible) mice display hyperactivity of VTA DA neurons, caused by an up-regulated hyperpolarization-activated current (I(h)). Mice resilient to social defeat stress, however, exhibit stable normal firing of these neurons. Unexpectedly, resilient mice had an even larger I(h), which was observed in parallel with increased potassium (K(+)) channel currents. Experimentally further enhancing Ih or optogenetically increasing the hyperactivity of VTA DA neurons in susceptible mice completely reversed depression-related behaviors, an antidepressant effect achieved through resilience-like, projection-specific homeostatic plasticity. These results indicate a potential therapeutic path of promoting natural resilience for depression treatment.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4334447/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4334447/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Friedman, Allyson K -- Walsh, Jessica J -- Juarez, Barbara -- Ku, Stacy M -- Chaudhury, Dipesh -- Wang, Jing -- Li, Xianting -- Dietz, David M -- Pan, Nina -- Vialou, Vincent F -- Neve, Rachael L -- Yue, Zhenyu -- Han, Ming-Hu -- F31 MH095425/MH/NIMH NIH HHS/ -- F32 MH096464/MH/NIMH NIH HHS/ -- R01 MH092306/MH/NIMH NIH HHS/ -- R01 NS060123/NS/NINDS NIH HHS/ -- T32 MH 087004/MH/NIMH NIH HHS/ -- T32 MH020016/MH/NIMH NIH HHS/ -- T32 MH087004/MH/NIMH NIH HHS/ -- T32 MH096678/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2014 Apr 18;344(6181):313-9. doi: 10.1126/science.1249240.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology and Systems Therapeutics, Icahn School of Medicine at Mount Sinai, New York, NY 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24744379" target="_blank"〉PubMed〈/a〉

    Description: 〈p〉Neuroadaptations in the nucleus accumbens (NAc) underlie cue-induced cocaine craving that intensifies ("incubates") during abstinence and is believed to contribute to persistent relapse vulnerability. Changes in gene expression often govern perpetual behavioral abnormalities, but epigenetic plasticity during prolonged abstinence from drug exposure is poorly understood. We examined how E3 ubiquitin ligase TRIM3 dysregulates chromatin remodeler INO80 to mediate cocaine craving during prolonged abstinence. We found that INO80 expression increased in the NAc on abstinence day 30 (AD30) but not on AD1 following cocaine self-administration. Furthermore, TRIM3, which mediates degradation of INO80, was reduced on AD30, along with TRIM3-INO80 interaction. Viral-mediated gene transfer of INO80 or TRIM3 governed cocaine craving during prolonged abstinence. Lastly, chromatin immunoprecipitation followed by massively parallel DNA sequencing identified INO80-mediated transcriptional regulation of predicted pathways associated with cocaine plasticity. Together, these results demonstrate a novel ubiquitin-proteasomal-epigenetic mechanism by which TRIM3-INO80 mediates cocaine craving during prolonged abstinence.〈/p〉

    Description: Many of the long-term effects of cocaine on the brain’s reward circuitry have been shown to be mediated by alterations in gene expression. Several chromatin modifications, including histone acetylation and methylation, have been implicated in this regulation, but the effect of other histone modifications remains poorly understood.
