    Rapid regulation of depression-related behaviours by control of midbrain dopamine neurons (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-12-14
    Description: Ventral tegmental area (VTA) dopamine neurons in the brain's reward circuit have a crucial role in mediating stress responses, including determining susceptibility versus resilience to social-stress-induced behavioural abnormalities. VTA dopamine neurons show two in vivo patterns of firing: low frequency tonic firing and high frequency phasic firing. Phasic firing of the neurons, which is well known to encode reward signals, is upregulated by repeated social-defeat stress, a highly validated mouse model of depression. Surprisingly, this pathophysiological effect is seen in susceptible mice only, with no apparent change in firing rate in resilient individuals. However, direct evidence--in real time--linking dopamine neuron phasic firing in promoting the susceptible (depression-like) phenotype is lacking. Here we took advantage of the temporal precision and cell-type and projection-pathway specificity of optogenetics to show that enhanced phasic firing of these neurons mediates susceptibility to social-defeat stress in freely behaving mice. We show that optogenetic induction of phasic, but not tonic, firing in VTA dopamine neurons of mice undergoing a subthreshold social-defeat paradigm rapidly induced a susceptible phenotype as measured by social avoidance and decreased sucrose preference. Optogenetic phasic stimulation of these neurons also quickly induced a susceptible phenotype in previously resilient mice that had been subjected to repeated social-defeat stress. Furthermore, we show differences in projection-pathway specificity in promoting stress susceptibility: phasic activation of VTA neurons projecting to the nucleus accumbens (NAc), but not to the medial prefrontal cortex (mPFC), induced susceptibility to social-defeat stress. Conversely, optogenetic inhibition of the VTA-NAc projection induced resilience, whereas inhibition of the VTA-mPFC projection promoted susceptibility. Overall, these studies reveal novel firing-pattern- and neural-circuit-specific mechanisms of depression.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3554860/" 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/PMC3554860/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chaudhury, Dipesh -- Walsh, Jessica J -- Friedman, Allyson K -- Juarez, Barbara -- Ku, Stacy M -- Koo, Ja Wook -- Ferguson, Deveroux -- Tsai, Hsing-Chen -- Pomeranz, Lisa -- Christoffel, Daniel J -- Nectow, Alexander R -- Ekstrand, Mats -- Domingos, Ana -- Mazei-Robison, Michelle S -- Mouzon, Ezekiell -- Lobo, Mary Kay -- Neve, Rachael L -- Friedman, Jeffrey M -- Russo, Scott J -- Deisseroth, Karl -- Nestler, Eric J -- Han, Ming-Hu -- F31 MH095425/MH/NIMH NIH HHS/ -- F32 MH096464/MH/NIMH NIH HHS/ -- K99 MH094405/MH/NIMH NIH HHS/ -- R01 MH092306/MH/NIMH NIH HHS/ -- R25 GM064118/GM/NIGMS NIH HHS/ -- T32 MH020016/MH/NIMH NIH HHS/ -- T32 MH087004/MH/NIMH NIH HHS/ -- T32 MH096678/MH/NIMH NIH HHS/ -- England -- Nature. 2013 Jan 24;493(7433):532-6. doi: 10.1038/nature11713.

    beta-catenin mediates stress resilience through Dicer1/microRNA regulation (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-11-11
    Description: beta-catenin is a multi-functional protein that has an important role in the mature central nervous system; its dysfunction has been implicated in several neuropsychiatric disorders, including depression. Here we show that in mice beta-catenin mediates pro-resilient and anxiolytic effects in the nucleus accumbens, a key brain reward region, an effect mediated by D2-type medium spiny neurons. Using genome-wide beta-catenin enrichment mapping, we identify Dicer1-important in small RNA (for example, microRNA) biogenesis--as a beta-catenin target gene that mediates resilience. Small RNA profiling after excising beta-catenin from nucleus accumbens in the context of chronic stress reveals beta-catenin-dependent microRNA regulation associated with resilience. Together, these findings establish beta-catenin as a critical regulator in the development of behavioural resilience, activating a network that includes Dicer1 and downstream microRNAs. We thus present a foundation for the development of novel therapeutic targets to promote stress resilience.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4257892/" 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/PMC4257892/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dias, Caroline -- Feng, Jian -- Sun, Haosheng -- Shao, Ning Yi -- Mazei-Robison, Michelle S -- Damez-Werno, Diane -- Scobie, Kimberly -- Bagot, Rosemary -- LaBonte, Benoit -- Ribeiro, Efrain -- Liu, XiaoChuan -- Kennedy, Pamela -- Vialou, Vincent -- Ferguson, Deveroux -- Pena, Catherine -- Calipari, Erin S -- Koo, Ja Wook -- Mouzon, Ezekiell -- Ghose, Subroto -- Tamminga, Carol -- Neve, Rachael -- Shen, Li -- Nestler, Eric J -- P50 MH096890/MH/NIMH NIH HHS/ -- R00 MH094405/MH/NIMH NIH HHS/ -- England -- Nature. 2014 Dec 4;516(7529):51-5. doi: 10.1038/nature13976.

    An almost ideal demand system for alcoholic beverages in British Columbia (1992)
    Springer
    Empirical economics 17 (1992), S. 401-418

    Topics: Economics
    Notes: Abstract An almost ideal demand system for alcoholic beverages in British Columbia is estimated based on five beverage categories. Estimates of the model unrestricted and restricted to satisfy homogeneity and symmetry are presented. The restrictions are tested: as is common in applied demand analysis a number of rejections are encountered, although within-equation tests tend to support homogeneity. The rejections which are encountered are not mitigated by the inclusion of dynamic elements. The Slutsky matrix is used to examine the concavity of the expenditure function, which is found to be mildly violated. Marshallian and Hicksian own-, cross-price, and income elasticities are calculated and are found to be largely consistent with previous findings, although some noteworthy results are obtained.

    Notes: Abstract A nucleoside triphosphatase (NTPase) activity appeared to be associated with a highly purified nuclear preparation from rat cardiac ventricles. Different nucleoside triphosphates (UTP 〉 GTP 〉 ITP 〉 CTP) supported this enzymic activity, which was stimulated by Mg` but not by Call. The nuclear NTPase activity could be down regulated by endogenous phosphorylation of a 55,000 Mr protein. Maximal phosphorylation of the 55,000 Mr protein occurred in the presence of Mg2+-ATP. Addition of cAMP, cGMP, Ca2+, Ca2+/phospholipid, Ca2+/calmodulin, and catalytic subunit of cAMP-dependent protein kinase was not associated with any further phosphorylation of the 55,000 Mr protein. However, in the presence of Ca2+/calmodulin or the catalytic subunit of the cAMP-dependent protein kinase additional proteins became phosphorylated, but these had no effect on the Mg2+-NTPase activity. These results indicate that a protein with Mr 55,000 may be involved in the regulation the Mg2+-NTPase activity associated with rat cardiac nuclei.

    Notes: Summary The appearance of the mucosal cell layer of the isolated urinary bladder of the toadBufo marinus, has been examined using stereoscopic and conventional transmission electron microscopy. Three cell types can be identified in surface view, these are granular cells, mitochondriarich cells and goblet cells. Cell boundaries between granular cells are clearly defined by membranous folds along their margins. Although no changes are seen in the stereoscopic electron micrographs when the granular cells are made permeable to water by vasopressin, the changes observed on transmission electron micrographs include swelling of cell bodies and nuclei, filling of intercellular channels with water, and the appearance beneath the mucosal cell membrane surface of electron dense granules. Differences between the appearance of the bladder mucosal cells by the two methods of electron microscopical examination are due largely to water loss when the tissue is freeze dried prior to stereoscopic examination.

    Notes: Summary The parenchyma of the normal “resting” human breast was examined by electron microscopy to characterize the cells undergoing mitosis and the mechanism by which the normal tissue architecture is maintained during this process. In this study of 112 mitotic cells, it was found that the mitotic cells were luminally positioned, polarised epithelial cells with no evidence of myoepithelial cell division. Ultrastructurally, the nuclear and cytoplasmic changes were consistent with previous reports of mitosis in other tissues. However, unlike all previous reports, two specific orientations of the nuclear spindle and thus the planes of cytokinesis were observed. In a few cases the spindle formed parallel to the lumen and division resulted in two luminally positioned daughter cells. However, in the majority of mitotic cells the spindle was approximately at right angles to the lumen and this orientation resulted in a luminally and a basally positioned daughter cell. It is proposed that the abnormally positioned basal daughter cell could develop into a myoepithelial cell or undergo deletion (apoptosis). Thus the two orientations of mitosis may explain the mechanism by which the epithelial and myoepithelial cell populations were maintained by a single progenitor cell without disrupting the integrity of the tissue architecture.
