    Identification of a thyroid hormone receptor that is pituitary-specific (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-04-07
    Description: Three cellular homologs of the v-erbA oncogene were previously identified in the rat; two of them encode high affinity receptors for the thyroid hormone triiodothyronine (T3). A rat complementary DNA clone encoding a T3 receptor form of the ErbA protein, called r-ErbA beta-2, was isolated. The r-ErbA beta-2 protein differs at its amino terminus from the previously described rat protein encoded by c-erbA beta and referred to as r-ErbA beta-1. Unlike the other members of the c-erbA proto-oncogene family, which have a wide tissue distribution, r-erbA beta-2 appears to be expressed only in the anterior pituitary gland. In addition, thyroid hormone downregulates r-erbA beta-2 messenger RNA but not r-erbA beta-1 messenger RNA in a pituitary tumor-derived cell line. The presence of a pituitary-specific form of the thyroid hormone receptor that may be selectively regulated by thyroid hormone could be important for the differential regulation of gene expression by T3 in the pituitary gland.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hodin, R A -- Lazar, M A -- Wintman, B I -- Darling, D S -- Koenig, R J -- Larsen, P R -- Moore, D D -- Chin, W W -- New York, N.Y. -- Science. 1989 Apr 7;244(4900):76-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Brigham and Women's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2539642" target="_blank"〉PubMed〈/a〉

    Cloning and expression of a rat brain GABA transporter (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-09-14
    Description: A complementary DNA clone (designated GAT-1) encoding a transporter for the neurotransmitter gamma-aminobutyric acid (GABA) has been isolated from rat brain, and its functional properties have been examined in Xenopus oocytes. Oocytes injected with GAT-1 synthetic messenger RNA accumulated [3H]GABA to levels above control values. The transporter encoded by GAT-1 has a high affinity for GABA, is sodium-and chloride-dependent, and is pharmacologically similar to neuronal GABA transporters. The GAT-1 protein shares antigenic determinants with a native rat brain GABA transporter. The nucleotide sequence of GAT-1 predicts a protein of 599 amino acids with a molecular weight of 67 kilodaltons. Hydropathy analysis of the deduced protein suggests multiple transmembrane regions, a feature shared by several cloned transporters; however, database searches indicate that GAT-1 is not homologous to any previously identified proteins. Therefore, GAT-1 appears to be a member of a previously uncharacterized family of transport molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guastella, J -- Nelson, N -- Nelson, H -- Czyzyk, L -- Keynan, S -- Miedel, M C -- Davidson, N -- Lester, H A -- Kanner, B I -- GM 10991/GM/NIGMS NIH HHS/ -- GM 29836/GM/NIGMS NIH HHS/ -- NS 16708/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1990 Sep 14;249(4974):1303-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1975955" target="_blank"〉PubMed〈/a〉

    Inactivation of TNF signaling by rationally designed dominant-negative TNF variants (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-09-27
    Description: Tumor necrosis factor (TNF) is a key regulator of inflammatory responses and has been implicated in many pathological conditions. We used structure-based design to engineer variant TNF proteins that rapidly form heterotrimers with native TNF to give complexes that neither bind to nor stimulate signaling through TNF receptors. Thus, TNF is inactivated by sequestration. Dominant-negative TNFs represent a possible approach to anti-inflammatory biotherapeutics, and experiments in animal models show that the strategy can attenuate TNF-mediated pathology. Similar rational design could be used to engineer inhibitors of additional TNF superfamily cytokines as well as other multimeric ligands.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Steed, Paul M -- Tansey, Malu G -- Zalevsky, Jonathan -- Zhukovsky, Eugene A -- Desjarlais, John R -- Szymkowski, David E -- Abbott, Christina -- Carmichael, David -- Chan, Cheryl -- Cherry, Lisa -- Cheung, Peter -- Chirino, Arthur J -- Chung, Hyo H -- Doberstein, Stephen K -- Eivazi, Araz -- Filikov, Anton V -- Gao, Sarah X -- Hubert, Rene S -- Hwang, Marian -- Hyun, Linus -- Kashi, Sandhya -- Kim, Alice -- Kim, Esther -- Kung, James -- Martinez, Sabrina P -- Muchhal, Umesh S -- Nguyen, Duc-Hanh T -- O'Brien, Christopher -- O'Keefe, Donald -- Singer, Karen -- Vafa, Omid -- Vielmetter, Jost -- Yoder, Sean C -- Dahiyat, Bassil I -- New York, N.Y. -- Science. 2003 Sep 26;301(5641):1895-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Xencor, 111 West Lemon Avenue, Monrovia, CA 91016, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14512626" target="_blank"〉PubMed〈/a〉

    Insulin-like growth factors: a role in growth hormone negative feedback and body weight regulation via brain (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-04-01
    Description: Intracerebroventricular administration of ILA's, a preparation enriched in insulin-like growth factors, caused a marked decrease in growth hormone secretory episodes and in body weight associated with reduced food intake over 24 hours. Central injection of insulin and bovine serum albumin had no such effects. These findings suggest that insulin-like growth factors play a role in growth hormone negative feedback and body weight regulation at the level of the central nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tannenbaum, G S -- Guyda, H J -- Posner, B I -- New York, N.Y. -- Science. 1983 Apr 1;220(4592):77-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6338593" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)

    Publication Date: 1980-03-07
    Description: Specific binding sites for blood-borne insulin were determined to be selectively localized on axons and axon terminals in the external median eminence and the hypothalamic arcuate nucleus by means of quantitative fine structural radioautography. This localization suggests that discrete populations of hypothalamic nerve terminals are potential targets for the direct effects of insulin and that insulin may act through synaptic mechanisms to influence hypothalamic circuits regulating energy balance and hypophyseal function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van Houten, M -- Posner, B I -- Kopriwa, B M -- Brawer, J R -- New York, N.Y. -- Science. 1980 Mar 7;207(4435):1081-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6986652" target="_blank"〉PubMed〈/a〉

    Protein kinase activity closely associated with a reconstituted calcium-activated potassium channel (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-08-02
    Description: Modulation of the activity of potassium and other ion channels is an essential feature of nervous system function. The open probability of a large conductance Ca(2+)-activated K+ channel from rat brain, incorporated into planar lipid bilayers, is increased by the addition of adenosine triphosphate (ATP) to the cytoplasmic side of the channel. This modulation takes place without the addition of protein kinase, requires Mg2+, and is mimicked by an ATP analog that serves as a substrate for protein kinases but not by a nonhydrolyzable ATP analog. Addition of protein phosphatase 1 reverses the modulation by MgATP. Thus, there may be an endogenous protein kinase activity firmly associated with this K+ channel. Some ion channels may exist in a complex that contains regulatory protein kinases and phosphatases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chung, S K -- Reinhart, P H -- Martin, B L -- Brautigan, D -- Levitan, I B -- DK31374/DK/NIDDK NIH HHS/ -- NS17910/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1991 Aug 2;253(5019):560-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate Department of Biochemistry, Brandeis University, Waltham, MA 02254.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1857986" target="_blank"〉PubMed〈/a〉

    Dopamine neurons modulate neural encoding and expression of depression-related behaviour (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-12-14
    Description: Major depression is characterized by diverse debilitating symptoms that include hopelessness and anhedonia. Dopamine neurons involved in reward and motivation are among many neural populations that have been hypothesized to be relevant, and certain antidepressant treatments, including medications and brain stimulation therapies, can influence the complex dopamine system. Until now it has not been possible to test this hypothesis directly, even in animal models, as existing therapeutic interventions are unable to specifically target dopamine neurons. Here we investigated directly the causal contributions of defined dopamine neurons to multidimensional depression-like phenotypes induced by chronic mild stress, by integrating behavioural, pharmacological, optogenetic and electrophysiological methods in freely moving rodents. We found that bidirectional control (inhibition or excitation) of specified midbrain dopamine neurons immediately and bidirectionally modulates (induces or relieves) multiple independent depression symptoms caused by chronic stress. By probing the circuit implementation of these effects, we observed that optogenetic recruitment of these dopamine neurons potently alters the neural encoding of depression-related behaviours in the downstream nucleus accumbens of freely moving rodents, suggesting that processes affecting depression symptoms may involve alterations in the neural encoding of action in limbic circuitry.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4160519/" 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/PMC4160519/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tye, Kay M -- Mirzabekov, Julie J -- Warden, Melissa R -- Ferenczi, Emily A -- Tsai, Hsing-Chen -- Finkelstein, Joel -- Kim, Sung-Yon -- Adhikari, Avishek -- Thompson, Kimberly R -- Andalman, Aaron S -- Gunaydin, Lisa A -- Witten, Ilana B -- Deisseroth, Karl -- DP2 DA035149/DA/NIDA NIH HHS/ -- F32 MH880102/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2013 Jan 24;493(7433):537-41. doi: 10.1038/nature11740.

    Maternal glucocorticoid hormones influence neurotransmitter phenotypic expression in embryos (1980)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1980-10-31
    Description: Treatment of pregnant rats with reserpine prevented the normal disappearance of catecholamine fluorescence in presumptive neuroblasts of the embryonic gut. These cells normally express the noradrenergic phenotype transiently during embryonic development. The effect of reserpine was reproduced by treating mothers with hydrocortisone acetate. Moreover, the reserpine effect was blocked by treatment with dexamethasone, which inhibits the stress-induced increase in plasma glucocorticoids, and by mitotone, which causes adrenocortical cytolysis. It is concluded that reserpine, through the mediation of maternal glucocorticoid hormones, alters the phenotypic expression of these embryonic neuroblasts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jonakait, G M -- Bohn, M C -- Black, I B -- HD 12108/HD/NICHD NIH HHS/ -- NS 06400/NS/NINDS NIH HHS/ -- NS 10259/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1980 Oct 31;210(4469):551-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7423206" target="_blank"〉PubMed〈/a〉
